Human colon adenocarcinomas express a MUC1-associated novel carbohydrate epitope on core mucin glycans defined by a monoclonal antibody (A10) raised against murine Ehrlich tumor cells. (1/764)

A monoclonal antibody (mAb; A10) raised against murine Ehrlich tumor cell surface carbohydrates was tested for reactivity with human normal and malignant tissues. A10 reacted strongly, with a high proportion of adenocarcinomas arising from colon and other tissues but not with breast carcinomas or other malignant tumors. Normal tissues were virtually A10 unreactive, except for the duct cells from breast and pancreas and some bronchial mucosae. Ultrastructural studies showed mAb A10 immunolabeling of both microvilli and mucin droplets in colon cancer cells but not in normal absorptive or globet cells. A10 reacted strongly with mucin-enriched fractions from colon cancer tissues and HT-29 xenografts but not from normal colon tissues. A10 epitope was carried on MUC1 derived from colon adenocarcinomas and probably on other mucin species, although not on MUC2 molecules. A10 epitope was resistant to exoglycosidases and periodate oxidation but sensitive to the Smith's degradation and beta-elimination, suggesting the involvement of O-linked carbohydrates in nonterminal reducing positions. A mucin-type glycosidic linkage was supported because of the lack of A10 reactivity with HT-29 cells grown with phenyl-N-acetyl-alpha-D-galactosaminide. Deglycosylation studies with trifluoromethanesulfonic acid pointed to the involvement of core mucin glycans in the A10 epitope. This epitope was resistant to protease, O- and N-glycanase treatments carried out on trifluoromethanesulfonic acid-deglycosylated mucins. Inhibition studies with core 1, core 2, core 3, and core 6 suggested the latter [GlcNAcbeta(1-6)GalNAc] as being involved in A10 epitope. Taken together, the present results point to A10 defining a core 6-related epitope on core mucin glycans expressed by colon cancer MUC1 not previously associated with human cancer.  (+info)

Dietary determinants of colorectal proliferation in the normal mucosa of subjects with previous colon adenomas. (2/764)

Dietary determinants of colorectal mucosa proliferation were studied in 69 subjects previously operated for at least two sporadic colon adenomas. Information on recent dietary habits was collected by a validated food frequency questionnaire, and proliferation was measured by [3H]thymidine incorporation in colorectal biopsies by determining the labeling index (LI) and the percentage of LI in the upper part of the crypt, two parameters that are increased in subjects at high risk of colon cancer. The LI was significantly higher in women as compared with men (P = 0.01). Diet showed several associations with colorectal mucosa proliferation: (a) subjects in the highest tertile of fish consumption had a significantly lower LI (P = 0.0013) compared with those in the lower tertiles [5.20 +/- 1.87 versus 6.80 +/- 2.18 (mean +/- SD)]; (b) subjects with a low red meat consumption had lower proliferation in the upper part of the crypt [2.38 +/- 2.10, 5.30 +/- 4.62, and 5.89 +/- 4.82 in the low, middle, and high tertile of consumption, respectively (mean +/- SD); P = 0.0093]; (c) according to estimated nutrient intakes, the LI was lower in subjects reporting a high intake of starch (P = 0.006) and higher in subjects with a low intake of beta-carotene (P = 0.002). The results show that subjects reporting a diet rich in fish, starch, and beta-carotene and low in red meat had lower colorectal mucosa proliferation and a normal pattern of proliferation along the crypt. Given the correlation between colorectal proliferative activity and colon cancer risk, such a dietary pattern might be beneficial for subjects at high risk of colon cancer.  (+info)

Differential expression of a new tumor-associated antigen, TLP, during human colorectal cancer tumorigenesis. (3/764)

Tumour liberated particles (TLP) have been proposed as a potential new serum tumor marker. In particular, a high percentage of patients with early stages of lung cancer scored positive for serum TLP, suggesting its possible role as a marker for early diagnosis of disease. The aim of the present study was to analyze the expression of TLP in the colorectal adenoma-carcinoma sequence in order to determine whether its expression correlates with the various stages of cancer transformation. TLP distribution was assessed by immunohistochemistry in normal, premalignant, and malignant colorectal lesions. Normal colonic mucosa and hyperplastic polyps showed no positive staining, whereas adenomas and adenocarcinomas reacted to anti-TLP serum. The percentage of positive tumor cells increased from adenomas with mild dysplasia to adenomas with severe dysplasia. Moreover, a supranuclear staining pattern was observed mainly in adenomas with mild dysplasia, whereas adenomas with severe dysplasia as well as adenocarcinomas showed a characteristic diffuse staining pattern and a strong staining intensity. Only a few cases of adenocarcinoma were found to be TLP-negative and all were poorly differentiated. Our results suggest that TLP antigen expression may be considered as a marker of epithelial atypia in the colorectal tract and as a potential target for new diagnostic and/or therapeutic approaches to human colorectal cancer.  (+info)

A bile acid-induced apoptosis assay for colon cancer risk and associated quality control studies. (4/764)

Bile acids are important in the etiology of colorectal cancer. Bile acids induce apoptosis in colonic goblet cells at concentrations comparable to those found in fecal water after high-fat meals. Preliminary evidence indicated that cells of the normal-appearing (nontumorous) portion of the colon epithelium of colon cancer patients are more resistant to bile salt-induced apoptosis than are cells from normal individuals. In the present study, 68 patients were examined, and biopsies were taken at 20 cm from the anal verge, cecum, and descending colon. The patients included 17 individuals with a history of colorectal cancer, 37 individuals with adenomas, and 14 individuals who were neoplasia free. The mean bile salt-induced apoptotic index among normal individuals was 57.6 +/- 3.47 (SE), which differed significantly (P < 0.05) from the mean value of 36.41 +/- 3.12 in individuals with a history of colon cancer. The correlation between independent observers was 0.89 (P < 0.001), indicating good interobserver reliability. Components of variance comparing interindividual versus intraindividual sources of variation suggested that site-to-site variability, both between regions of the colon and for adjacent biopsies, was larger than the interpatient variability for individuals with a history of neoplasia. Therefore, there was "patchiness" of the susceptibility of regions of the colon to bile acid-induced apoptosis in individuals with a history of neoplasia (a patchy field effect). There was no obvious correlation of low-apoptotic index regions with regions in which previous neoplasias had been found and removed. On the other hand, for normal, i.e., neoplasia-free, individuals, there was relatively less intraindividual variation compared to interindividual variation. Our assay shows an association between resistance to bile acid-induced apoptosis, measured at 20 cm from the anal verge, and colon cancer risk. Thus, this assay may prove useful as a biomarker of colon cancer risk.  (+info)

Frequent mutation of beta-catenin and APC genes in primary colorectal tumors from patients with hereditary nonpolyposis colorectal cancer. (5/764)

Hereditary nonpolyposis colorectal cancer (HNPCC) is characterized by defective DNA mismatch repair, which results in genetic instability of tumors; however, only a few target genes have been recognized. Our previous study detected a low frequency of APC gene mutation (21%) in colorectal tumors from HNPCC patients, in contrast to a high frequency of APC gene alteration (>70%) in non-HNPCC tumors. Because both beta-catenin and ACP gene mutations have recently been shown to activate the same signaling pathway, we analyzed beta-catenin mutation in HNPCC tumors. A notable frequency of beta-catenin gene mutation (43%, 12 of 28) was found to occur in HNPCC colorectal tumors. Beta-catenin mutations were not detected in tumors with APC mutations. All beta-catenin mutations detected in HNPCC tumors existed within the regulatory domain of beta-catenin. Immunohistochemical staining of tumors with this mutation showed accumulation of beta-catenin protein in nuclei. These and previous data from our laboratory suggest that activation of the beta-catenin-Tcf signaling pathway, through either beta-catenin or APC mutation, contributes to HNPCC colorectal carcinogenesis in approximately 65% of cases.  (+info)

Up-regulation of macrophage wnt gene expression in adenoma-carcinoma progression of human colorectal cancer. (6/764)

Defects in the APC-beta-catenin pathway are common in colon cancer. We investigated whether aberrant regulation of upstream ligands stimulating this pathway occur in colon cancer. Using RNAase protection analysis, six out of eight wnt genes were expressed in 14 matched cases of normal, adenomatous and malignant colorectal tissues. Wnt 2 and wnt 5a were significantly up-regulated in the progression from normal through adenoma to carcinoma. Transcripts for wnts 4, 7b, 10b and 13, but not wnt 2 and wnt 5a were detected in several colorectal cell lines. In situ hybridization demonstrated that wnt 2 and wnt 5a transcripts were mainly in the lamina propria/stroma region with labelling predominantly in macrophages. Immunostaining with CD68 confirmed the wnt-expressing cells as macrophages. These results show a major difference in wnt expression in colon cancer compared to colon adenomas and suggest stromal wnt expression may play a role in tumour progression.  (+info)

A comparison of virtual and conventional colonoscopy for the detection of colorectal polyps. (7/764)

BACKGROUND: Virtual colonoscopy is a new method of imaging the colon in which thin-section, helical computed tomography (CT) is used to generate high-resolution, two-dimensional axial images. Three-dimensional images of the colon simulating those obtained with conventional colonoscopy are then reconstructed off-line. We compared the performance of virtual and conventional colonoscopy for the detection of colorectal polyps. METHODS: We prospectively studied 100 patients at high risk for colorectal neoplasia (60 men and 40 women; mean age, 62 years). We performed virtual colonoscopy immediately before conventional colonoscopy. We inserted a rectal tube and insufflated the colon with air to the maximal level that the patient could tolerate. We administered 1 mg of glucagon intravenously immediately before CT scanning to minimize the degree of smooth-muscle spasm and peristalsis and to reduce the patient's discomfort. RESULTS: The entire colon was clearly seen by virtual colonoscopy in 87 patients and by conventional colonoscopy in 89. Fifty-one patients had normal findings on conventional colonoscopy. In the other 49, we identified a total of 115 polyps and 3 carcinomas. Virtual colonoscopy identified all 3 cancers, 20 of 22 polyps that were 10 mm or more in diameter (91 percent), 33 of 40 that were 6 to 9 mm (82 percent), and 29 of 53 that were 5 mm or smaller (55 percent). There were 19 false positive findings of polyps and no false positive findings of cancer. Of the 69 adenomatous polyps, 46 of the 51 that were 6 mm or more in diameter (90 percent) and 12 of the 18 that were 5 mm or smaller (67 percent) were correctly identified by virtual colonoscopy. Although discomfort was not specifically recorded, none of the patients requested that virtual colonoscopy be stopped because of discomfort or pain. CONCLUSIONS: In a group of patients at high risk for colorectal neoplasia, virtual and conventional colonoscopy had similar efficacy for the detection of polyps that were 6 mm or more in diameter.  (+info)

Patterns of proliferative changes in crypts bordering colonic tumors: zonal histology and cell cycle marker expression. (8/764)

Proliferative crypt changes have been noted in mucosa bordering colonic carcinomas, but their biological significance is disputed. We anticipated that zonal patterning of histological changes and cell cycle marker expression would provide clues to the pathogenesis of these border changes. 81 specimens were examined including carcinomas, adenomatours polyps, adenomas with early carcinoma, flat adenomas and aberrant crypt foci. The spatial distribution and frequency of micro-architectural features, and mucosal thickness were determined in a border domain of 150 300 sequential crypts/specimen. Immunocytochemical expression of Ki67 and p53 antigens in crypts also was semi-quantitatively examined. We found that in 100% of carcinomas two histologically abnormal zones (Proximate and Middle) separated tumor from normal mucosa. Differences in the feature frequency between zones were statistically significant (p<0.05). Both zones showed mild increases in crypt cell expression of Ki67, with a statistically significant relationship to zonal patterning (p<0.005). Weak expression of p53 only appeared in rare cells. Crypt elongation with mucosal thickening (1.9x normal, p<0.001) in the Proximate and Middle zones distinguished carcinomas from border changes in all benign lesions, except flat adenomas. Since this change occurs in all cases of carcinoma, there is no correlation with tumor stage or grade. Also in carcinomas, elaborate complexes of attached crypts (connected crypt structures) were characteristic of the Middle zone, so that proximate zone was always architecturally simpler. We conclude, that despite continuous carcinoma growth, the invaded border mucosa maintains a prototypical zonal organization of molecular and histological crypt changes This spatially organized reaction pattern is likely to reflect an interplay between regulated growth and destructive processes in response to advancing carcinoma. Compared to the edges of benign colonic tumors, the edges of carcinomas are distinctive and consistent enough to be diagnostically useful.  (+info)

A colonic polyp is a protrusion in the lining of the bowel caused by an abnormal production of cells. It may be a tiny raised area; it may look like a grape or take the form of many tiny projections clustered together. Polyps are very common (occurring in 15-20% of the population) and most are not cancerous. Polyps should be removed if found as some may eventually (over many years) become a cancer in the colon (large bowel) or rectum (back passage).. Symptoms of colonic polyps. Most people are unaware of having polyps as they usually produce no symptoms and are often an incidental finding. Some polyps can however cause rectal bleeding or an excess production of mucus (slime) with bowel motions. Polyps are usually found as a result of bowel investigations - such as a sigmoidoscopy or barium enema. If they are found colonoscopy is required to view the whole of the large bowel and remove the polyp(s).. Treatments for colonic polyps. The most common method of removal is by:. ...
The teams analyses included 5433 participants with 2 colonoscopies. The researchers used multivariable logistic regression models to assess effects of index serrated polyps, high-risk adenomas, low-risk adenomas, and no adenomas on subsequent high-risk adenomas or large serrated polyps on surveillance colonoscopy. Synchronous serrated polyps, within each index risk group, were assessed for size and by histology. Serrated polyps comprize hyperplastic polyps, sessile serrated adenomas/polyps, and traditional serrated adenomas. The doctors referred to sessile serrated adenomas/polyps and traditional serrated adenomas collectively as STSAs.. High-risk adenomas and synchronous large serrated polyps, high-risk adenomas with synchronous STSA, and high-risk adenomas alone at index colonoscopy significantly increased the risk of metachronous high-risk adenomas compared to the reference group. Large index serrated polyps alone or index STSA alone significantly increased the risk of a large metachronous ...
TY - JOUR. T1 - Ultraviolet laser-induced fluorescence of colonic polyps. AU - Schomacker, Kevin T.. AU - Frisoli, Joan K.. AU - Compton, Carolyn C.. AU - Flotte, Thomas J. AU - Richter, James M.. AU - Deutsch, Thomas F.. AU - Nishioka, Norman S.. PY - 1992. Y1 - 1992. N2 - Ultraviolet laser-induced fluorescence was examined in vivo to determine whether the technique can reliably distinguish between hyperplastic and adenomatous polyps of the colon. Spectra from 86 normal colonic sites, 35 hyperplastic polyps, and 49 adenomatous polyps were recorded in vivo. Polyp type was independently determined by two senior pathologists who were unaware of the fluorescence measurement. A multivariate linear regression analysis was used to differentiate spectra from hyperplastic and adenomatous polyps and resulted in a sensitivity, specificity, predictive value positive, and predictive value negative for identifying adenomatous polyps of 86%, 80%, 86%, and 80%, respectively. These values were not significantly ...
Introduction Knowing if polyps are larger than 10mm is critical when determining colonoscopic surveillance strategies. Judging polyp size from the endoscopic view alone becomes important if polyps are not retrieved intact. Strategies based on deliberately discarding small polyps rely on accurate discrimination of polyp size but little is known about endoscopists ability to make this judgement. Our aim is to assess the accuracy of polyp size estimation using a novel in vitro model, comparing different professional groups and use of accessories to improve estimates. ...
TY - JOUR. T1 - High colonoscopic prevalence of proximal colon serrated polyps in average-risk men and women. AU - Kahi, Charles J.. AU - Li, Xiaochun. AU - Eckert, George J.. AU - Rex, Douglas K.. PY - 2012/3/1. Y1 - 2012/3/1. N2 - Background: Proximal colon serrated polyps likely contribute to the decreased protection of colonoscopy against right-sided colorectal cancer. Objective: To estimate the prevalence and extrapolated detection rate of proximal serrated polyps at screening colonoscopy. Design: Retrospective study. Patients: The study involved secondary analyses that used two databases. The first includes screening colonoscopies performed by 15 attending gastroenterologists at two academic endoscopy units between 2000 and 2009. The second includes average-risk patients who had previously participated in a randomized trial comparing high-definition chromocolonoscopy and white-light colonoscopy. Main Outcome Measurements: Prevalence of proximal serrated polyps found by the highest-level ...
Results Seen in 83 men and 65 women ranging in age from 32 to 89 years and 127 were left sided with 22 in the right colon. Seventy-eight of the 149 TSAs showed evidence of another polyp (52.34%): 32 were low-grade tubular/tubulovillous adenomas (TAs/TVAs; 41%), 28 were HPs (36%) and 18 were SSAs (23%). Eleven of the 22 right-sided TSAs were associated with a precursor lesion (1 HP and 7 SSA). In addition, five TSAs showed more than one polyp type: TSA with TA/TVA and HP (3); TSA with TA/TVA and SSA (2). The TAs/TVAs were adjacent to the TSA but occurred as a separate discrete polyp, while HPs and SSAs were intermingled with the TSA and present at the base and surface of the lesion.. ...
A technique for lectin-peroxidase histochemistry was adapted for the study of formalin fixed paraffin embedded colonic tissue. Ten lectins with differing carbohydrate binding specificity were tested against 20 normal rectal biopsy specimens and tissue from 19 colonic carcinomata, 19 tubular or tubulovillous adenomata, and 19 hyperplastic polyps. None of the normal rectal biopsy specimens bound the lectins peanut agglutinin (PNA), Griffonia simplicifolia II (GSII), and Ulex europaeus I (UEAI), whereas 18 carcinomata, 12 adenomata, and 18 hyperplastic polyps showed affinity for one or more of these lectins. Hyperplastic colonic polyps are shown to possess similar abnormalities in glycoprotein structure to malignant and adenomatous colonic tissue. This may simply indicate a non-specific reaction to changed rates of cell proliferation but might represent a more fundamental association between hyperplastic polyps and adenocarcinomas.. ...
Early detection of colon polyps is important since most colon cancer develops slowly from colon polyps. The first step in diagnosing colon polyps and colon cancer is a good evaluation.
Colonoscopy is the gold standard screening test for colorectal cancer. Removal of pre-malignant colon polyps during colonoscopy reduces colorectal cancer mortality by over 50%. However, while colonoscopy is highly effective at preventing distal (left sided) colon cancers, it provides only limited protection from cancer in the proximal (right side) colon. Our goal is to determine if additional pre-cancerous colon polyps can be identified by looking at the right side of the colon in retroflexion. During retroflexion the tip of the colonoscope is turned 180 degrees; allowing the doctor to view the backs of colonic folds. If additional polyps can be identified in this manner colonoscopy will become a more efficient method of screening for colon cancer.. In order to evaluate how effective right colon retroflexion is at detecting polyps in the proximal colon we plan on performing a randomized, controlled trial. Patients undergoing screening or follow up colonoscopy will be invited to participate in ...

Colon polyp. Coloured 3D computed tomography (CT) scan of a pedunculated (stalked) polyp in the colon (large intestine) of a patient. Polyps are benign (non-cancerous) growths that arise from mucous membranes. Although benign, polyps are generally removed surgically as their growth may obstruct the passage of food, and some polyps may turn cancerous over time. - Stock Image C026/9026
Background The aim of this study was to establish if endoscopists can reliably self-assess their ability to perform simulated colonic polypectomy. Methods Novices, intermediates, advanced, and experts performed a video-recorded polypectomy task using the Welsh Institute for Minimal Access Therapy (WIMAT) colonoscopy suitcase simulator. This involved removal of a simple polyp (A) and a complex polyp (B). Participants self-assessed themselves using a Direct Observation of Polypectomy Skills (DOPyS) assessment form. Two blinded, independent, Joint Advisory Group on Gastrointestinal Endoscopy (JAG) accredited assessors graded each performance using the same DOPyS scoring. The Spearman coefficient was used to determine the correlation between self and assessors scores. Results Eighty participants completed the task. There was a weak correlation between assessors scores and self-assessment scores for all groups (novices: ρ = −.44, P = .85; intermediates: ρ = −.16, P = .51; advanced: ρ = .16, ...
Results: Seven patients were recruited (five male; mean age 66 years). Polyps were from 20 to 50mm in diameter (mean 30mm), six were in the right colon, and three were on the mesenteric border of the bowel. Final pathology was benign in all cases. Mean EMR time was 29 minutes, mean time taken for TAS was 37 minutes, and mean total operative time was 129 minutes. Two TAS procedures required conversion to LC (one unresectable polyp and one device failure). Five TAS procedures were completed, with a mean hospital stay of 1.2 days, and no complications. Follow-up colonoscopy revealed complete healing in all cases, with no recurrence of polyp to the current time. One patient (initial 5cm sigmoid polyp) had a very mild asymptomatic stricture in the sigmoid colon ...

AIM: To examine the efficacy and complications of colonoscopic resection of colorectal polypoid lesions. METHODS: We retrospectively reviewed 1354 polypectomies performed on 1038 patients over a ten-year period. One hundred and sixty of these were performed for large polyps, those measuring ,= 20 mm. Size, shape, location, histology, the technique of polypectomy used, complications, drugs assumption and associated intestinal or extra intestinal diseases were 2 analyzed. For statistical analysis, the Pearson chi(2) test, NPC test and a Binary Logistic Regression were used. RESULTS: The mean patient age was 65.9 +/- 12.4 years, with 671 men and 367 women. The mean size of polyps removed was 9.45 +/- 9.56 mm while the size of large polyps was 31.5 +/- 10.8 mm. There were 388 pedunculated and 966 sessile polyps and the most common location was the sigmoid colon (41.3%). The most frequent histology was tubular adenoma (55.9%) while for the large polyps was villous (92/160 -57.5%). Coexistent ...

Hyperplastic polyps of the colon are common benign lesions. They frequently arise at the crest of a mucosal fold where they present as small, sessile polyps usually measuring less than 5 mm in diameter with a smooth convex surface.1 Although traditionally regarded as non-neoplastic, recent evidence has shown hyperplastic polyps to have molecular features of neoplasia.2 Histologically they have a very characteristic appearance of elongated crypts with prominent epithelial infoldings giving a pathognomonic serrated pattern. The majority of hyperplastic polyps occur in the rectosigmoid where they may be single or often multiple; however their numbers rarely exceed 10.1 The occurrence of multiple or large hyperplastic polyps in the large bowel is termed hyperplastic polyposis coli.1 3 4 Hyperplastic polyposis coli is a rare condition characterised by the presence of large multiple hyperplastic polyps, some of which may show dysplasia, an occurrence that is felt to contribute significantly to the ...
Colon Polyps A colon polyp is a growth of extra tissue in the lining of the rectum or colon. While some can be cancerous, most are not. However, almost all colon cancer does begin as a polyp. Therefore, by removing polyps early, the chances of it growing into colon cancer are eliminated. People with a higher risk for developing polyps are anyone over age 50, those who have had polyps previously or those who have a family history of polyps or colon cancer. However you can still be at risk for polyps or colon cancer without having a family history of either condition. In fact, 80 percent of those who are diagnosed with colon cancer have no family history. Polyps generally do not cause symptoms. If a patient does have symptoms, they can include blood in their underwear or on toilet paper after a bowel movement, blood in stool, or constipation or diarrhea that has lasted more than a week. Polyps can be removed during a colonoscopy. If precancerous colon polyps are removed, the chance of the polyp ...

Scheduled for a colonoscopy? Ask your physician to play Mozart while shes peering through that endoscope, and she may do a better job of detecting potentially cancerous polyps in your colon and rectum, called adenomas. Colonic polyps are common precursors to colon cancer. Adenomas are a type of polyp that may develop into invasive colorectal cancer. Adenocarcinoma of the colon is the most common form of colorectal cancer.
What is the best diagnostic test to use in the workup of rectal bleeding and other gastrointestinal symptoms? To the old debate between barium enemas and colonoscopy (1) can now be added a new modality, hydrocolonic sonography. Although conventional transabdominal ultrasonography has not proved useful in the evaluation of large bowel neoplasia, the instillation of water in the colon is a clever innovation. Limberg has previously shown its efficacy in the diagnosis of inflammatory bowel disease (2). The article by Limberg is an update of an earlier study by this investigator (3), confirming its efficacy in diagnosing colorectal neoplasia in a series of apparently typical patients referred for colonoscopy. It almost equals the sensitivity of colonoscopy in identifying carcinomas and large polyps. Its real competition, however, is with barium enemas, with which it has comparable efficacy, but hydrocolonic sonography avoids radiographic exposure and adds the ability to evaluate the bowel wall and ...
A polyp is a general name for a benign warty growth of the lining of any organ. If the growth arises from the large bowel or colon it is a colonic polyp. Find out about the types of colonic polyp.
A: Colonic polyps are collections of cells arising and protruding from the inside lining of the colon. About two-thirds of colonic polyps are benign tumors (non-cancerous adenomas), most others being hyperplastic tissue (abnormal proliferation of cells) or other benign growths.
The colon is an important part of the digestive system. It is the last portion of this complex system, responsible for the important extraction of salt and water from solid waste, prior to excretion. The human colon consists of four sections. They are identified as the rising, transverse, coming down, and the sigmoid segments. The development of polyps or abnormal tissue development within the colon is commonly observed in people who are overweight. Colon polyps are also observed in people who extensively enjoy smoking, a diet plan that is high in fat and low in fiber, as well as those who have a family history of the condition ...

But talk it over with your surgeon.
Results A total of 1438 colonoscopies were reviewed. Polyps were found and removed in 314 (22%). Only 205 were included in further analysis. The remaining 109 were excluded because further follow-up indication was based on different issues (12 IBD, 19 colon cancers, 34 technical problems, 21 unknown previous risk status, 23 referred for surgery). Of the included 205, 34 patients were given an appointment in 1 year (high risk), one in 2 years, 28 in 3 years (intermediate risk), 142 in 5 years or no follow-up (low risk). The follow-up indication was compliant with BSG guidelines in 136 (66.3%) cases. In 33 (16.1%) patients the follow-up appointment was scheduled too early and in 4 (2%) too late. The remaining 32 (15.6%) were booked for later decision in outpatient clinic. They belonged to the intermediate (No.=28) and high (No.=4) risk groups. Overall, in the 3-months period, 24 inappropriate colonoscopies and 32 extra outpatient appointments were scheduled for the following year alone. In a ...

Results have been inconsistent on the protective effect of calcium and magensium intake on colorectal cancer and adenoma. We found recently in the Tennessee Colorectal Polyp Study (TCPS; P50CA95103) that the associations between intake of calcium or magnesium and risk of colorectal adenoma and hyperplastic polyps may differ by the common Thr1482Ile polymorphism of the TRPM7 gene, a gene involved in calcium and magnesium (re)absorption and homeostasis. Our finding may partially explain the inconsistency in previous studies on calcium and magnesium. In addition, we found that the ratio of calcium to magnesium intake significantly interacted with the Thr1482Ile polymorphism in relation to both adenomatous and hyperplastic polyps. In response to PAR-07-377, we propose a clinical epidemiologic study to test several novel hypotheses regarding gene-nutrition interactions using data and biological samples collected as part of the TCPS, a large on-going molecular epidemiologic case-control study of ...

Results: There were 193 patients with colorectal cancer and colorectal polyps compared with 206 control patients investigated in the same hospital. From the study group, 53 patients (27.46%) were current smokers compared with control patients 27 patients (13.10%). As a result of this comparison there was a significant association with an increased risk for colorectal cancer and colorectal polyps (OR = 2.77, CI: 1.64-4.67). It was also observed a significant increased tendency of the risk for the colorectal polyps and colorectal cancer in parallel with the increase of the number of smoked cigarettes per day and years of cigarette smoking (, 10 cigarettes/day - OR = 1.03, CI: 0.45-2.33; 10-20 cigarettes/day - OR = 4.47, CI: 1.73-10.55; , 20 cigarettes/day - OR = 5.41, CI: 2.13-13.72 and , 10 years of cigarette smoking OR = 1.41, CI: 0.63-3.16; 10-20 years of cigarette smoking OR = 3.63, CI: 1.46-8.98; , 20 years of cigarette smoking OR = 4.43, CI: 1.83-10.74 ...

Since its original characterization, studies of the ApcMin/+ mouse established a firm link between increased Wnt/βC activation and development of colonic polyps. However, few studies have investigated whether there is a vascular phenotype in these animals, or whether APC might play a role in tumor pathogenesis independent of Wnt signaling. A study by Bhandaru et al26 demonstrated that, compared with C57 controls, ApcMin/+ mice have higher than normal blood pressure and blood volume as a consequence of increased aldosterone levels and reduced glomerular filtration. In our study, we found only a trend toward higher systemic blood pressures in ApcMin/+ mice using tail-cuff measurements. Our results may be related to lower salt content in the diet, the timing of the blood pressure measurements (early morning versus afternoon), and a smaller sample size. Furthermore, hypoxia is known to trigger systemic vasodilatation and to inhibit the release of aldosterone from the adrenal glands, thus, promoting ...
This test measures different kinds of DNA changes, known as methylation and mutation, along with a measure of fecal blood. By combining these measures, we can look for the kinds of biological changes that are most frequently found in precancers and cancers in the colon," said Graham P. Lidgard, Ph.D., senior vice president of research and development and chief science officer at Exact Sciences, which developed the test and sponsored the study. Lidgard and colleagues analyzed 1,003 patient samples from 36 study sites and developed an analytic algorithm for the novel, automated stool DNA-based test platform, which generated a positive or negative result for each patient. The specimens were collected either before colonoscopy bowel preparation in screening and surveillance patients or at least seven days post-colonoscopy from patients with colorectal cancer and large precancers.. The control group included 796 patients with negative colonoscopies or small polyps (less than 1 cm), and the case group ...

Hi. Have been having chest pain under my left breast for the past 3 days with the feeling of fainting as well. Went to walk-in today as I was scared. They did an ECG but it came back normal. My blood pressure is O.K. sitting or standing. But when she checked my heart rate from sitting to standing it jumped significantly. So she has suggested a Holter monitor. Of course like everything I have to wait. this is not going to happen until a month from now. how is that going to help me today? the only other option she can see is the CT scan but they take forever to get into as well. I did however today get the results that my Gastroscopy all came back fine and that there is nothing wrong in that area. Also my gall bladder has 1 small polyp on it and she doesnt think that would cause me any pain. Plus the pain is under my left breast instead of my right.

Colorectal cancer is the second leading cause of cancer death in the United States and fourth worldwide. Colorectal cancer often develops from precancerous polyps which, when found early, may be easily and safely removed. Colorectal polyps are often asymptomatic and are typically detected through routine optical colonoscopy (OC) screening. While there have been many advancements in polyp detection and OC, roughly 22% of polyps still go undetected during an OC screen and 4-6% of diagnosed colorectal cancers are thought to have been missed on prior colonoscopies. Because the incidence and mortality of colorectal cancer decreases with early detection, it is important to reduce the rates of undetected polyps. Researchers at Arizona State University in collaboration with Dr. Gurudu of the Mayo Clinic have developed two novel systems for computer-aided detection of polyps in optical colonoscopy images. The first system detects polyps by using boundary classifiers and a voting scheme to automatically ...

Methods: Colonoscopy is a technique for examine colon cancer, polyps. In endoscopy, video capsule is universally used mechanism for finding gastrointestinal stages. But both the mechanisms are used to find the colon cancer or colorectal polyp. The Automatic Polyp Detection sub-challenge conducted as part of the Endoscopic Vision Challenge (http://endovis.grand-challenge.org). Method: Colonoscopy may be primary way of improve the ability of colon cancer detection especially flat lesions. Which otherwise may be difficult to detect. Recently, automatic polyp detection algorithms have been proposed with various degrees of success. Though polyp detection in colonoscopy and other traditional endoscopy procedure based images is becoming a mature field, due to its unique imaging characteristics, detecting polyps automatically in colonoscopy is a hard problem. So the proposed video capsule cam supports to diagnose the polyps accurate and easy to identify its pattern. Existing methodology mainly concentrated on

AU - Garewal, H.. PY - 1990/11/21. Y1 - 1990/11/21. N2 - An important determinant in interpreting the results of colorectal polyp chemoprevention trials is the rate of polyps missed during colonoscopic examination. We prospectively examined 90 patients by tandem colonoscopy performed by two alternating examiners. In 69 (76.7%) patients, 221 neoplastic lesions were documented histologically. Of a total of 58 lesions detected in 31 patients, no neoplastic lesion greater than or equal to 10 mm in size was missed; 16% of diminutive (≤5 mm) neoplastic polyps and 12.3% of mediumsized (6-9 mm) neoplastic polyps were missed by the first examiner. We conclude that an experienced colonoscopist will miss about 15% of colorectal neoplastic polyps less than 10 mm in size in the setting of adequate bowel preparation. ...
INTRODUCTION. Computed tomography colonography (CTC), or virtual colonoscopy, is an imaging method based on the acquisition of multiple sections obtained by multidetector computed tomography (MDCT), generating sectional views of the colon that later can be reformatted in multiple planes and also processed in to allow endoluminal navigation, as in optical colonoscopy (OC)(1) . Among its main advantages, this method is fast, as the examination is performed in less than 15 minutes, without requiring sedation. For over a decade, CTC has been utilized in the investigation of colonic polyps and colorectal cancer (CRC). Developments in the clinical and epidemiological knowledge on CRC and the many technological advances incorporated by CTC have transformed the method from an investigation tool into a viable option for CRC screening(2 4) .. The method is less invasive than OC for the screening of polyps and may preferably be utilized in asymptomatic individuals with low risk for development of CRC, in ...
Most colorectal cancers evolve from colorectal adenomatous polyps in a pathway known as the adenoma to carcinoma sequence. Early detection and removal of colorectal adenomas can prevent the development of colorectal cancer. The vast majority of these polyps can be resected endoscopically. Advances in endoscopic resection techniques have led to expanded indications for endoscopic polypectomy, whereby giant polyps, scarred lesions and early cancers may be cured. We will outline conventional endoscopic mucosal resection techniques as well as more complex resection methods such as endoscopic submucosal dissection, full thickness resection and the use of combined endoscopic and laparoscopic assisted approaches to resection. We will also explore the role of a virtual multidisciplinary team to aid decision-making when managing large and complex colorectal polyps. This review will provide an update on the endoscopic management of colorectal polyps and highlight exciting new developments in this ...
The reef aquarium hobby long ago divided stony corals into two categories, Large Polyp Stony (LPS) and Small Polyp Stony (SPS). This view is somewhat antiquated, but still serves as a guideline for care where SPS are thought to require more expert care than their LPS counterparts. The thinking behind this is on the whole LPS are more tolerant to water quality than SPS and SPS tend to require very intense light and flow. As with any rule, there are a multitude of exceptions so we encourage reef hobbyists to research each of the SPS corals individually to determine their care requirements. For example, there is a world of difference between an Acropora and a Seriatopora when it comes to coral husbandry.
We examined whether PDR and subsequently ADR could be increased using the WT as a surrogate marker via the Hawthorne effect (knowing that the WT was assessed) and feedback (provided after the first study phase). Furthermore, the retention of knowledge gained within the organisation was assessed by a 1-year follow-up.. Information and feedback after the first phase had a significant impact on PDR, which almost doubled (22% vs 42%). The endoscopists were focusing on PDR through the surrogate marker (WT) and the feedback given. The PDRs increased at all levels of monitored WTs. The mean WT did, however, not increase significantly in between the first and second phases. Thus, monitoring and feedback appears to be crucial factors for the increase in PDR and not the measured parameter (ie, the WT itself). The increase in PDR was additionally mirrored in an increased ADR. The increased PDR/ADR was found to be maintained, and thus the endoscopy team was able to maintain focus on the importance of PDR ...

Although serrated polyps were historically considered to pose little risk, it is now understood that progression down the serrated pathway could account for as many as 15%-35% of colorectal cancers. The sessile serrated adenoma/polyp (SSA/P) is the most prevalent pre-invasive serrated lesion. Our objective was to identify the CpG loci that are persistently hyper-methylated during serrated carcinogenesis, from the early SSA/P lesion through the later cancer phases of neoplasia development. We queried the loci hyper-methylated in serrated cancers within our rightsided SSA/Ps from the New Hampshire Colonoscopy Registry, using the Illumina Infinium Human Methylation 450 k panel to comprehensively assess the DNA methylation status. We identified CpG loci and regions consistently hyper-methylated throughout the serrated carcinogenesis spectrum, in both our SSA/P specimens and in serrated cancers. Hyper-methylated CpG loci included the known the tumor suppressor gene RET (p = 5.72 x 10−10), as well as loci
TY - JOUR. T1 - In vitro models of human colonic adenomatous polyps.. AU - Willson, J. K.. AU - Bittner, G. N.. PY - 1988. Y1 - 1988. N2 - In this report we describe methods which were used to cultivate cell lines from adenomatous polyps. Many of the techniques used have evolved from our past experience with the cultivation of colonic epithelial neoplastic cells (McBain et al., 1984) and the experience of others successful in the cultivation of benign and cancerous colon tissues. We feel that the preservation of cell-to-cell associations is a key to our successful cultivation of adenomas. Moyer (Moyer and Aust, 1984) has also pointed out the importance of preserving cell-to-cell associations in her successful studies to culture normal and neoplastic colonic tissues. Friedmans primary culture system for adenomatous polyps (Friedman et al., 1981) is further evidence supporting this point. Using the techniques described in this report, three cell lines, two small tubular polyps and one villous ...
June 20, 2008 - iCAD Inc. said it has initiated a clinical study for Colon CAD, its virtual colonoscopy CAD product, in partnership with ACR Image Metrix, a subsidiary of the American College of Radiology (ACR).. iCAD and ACR Image Metrix, having completed the development portion of the study, are collaborating on study execution including a multi-reader, multi-case (MRMC) clinical study designed to assess the impact of Colon CAD on the accuracy of interpreting CT Colonography exams also known as virtual colonoscopies. The study will also assess the sensitivity of Colon CAD for detecting polyps and will measure the impact of iCADs CT Colon CAD product on interpretation and workflow.. Virtual colonoscopy offers patients a less invasive option to conventional colonic polyp detection techniques. According to the company, reviewing these images can be tedious and challenging because of the amount of information captured in a CT exam. ICADs colon CAD product uses sophisticated image processing ...
Screening for colorectal cancer with fecal occult blood testing and lower endoscopy with removal of polyps reduce the mortality rate from colorectal cancer. Screening with flexible sigmoidoscopy is becoming standard for asymptomatic persons older than 50 years. Because adenomatous polyps found in the distal colon have been associated with adenomatous polyps in the proximal colon, full colonoscopy is generally recommended for patients with distal adenomas. Small polyps (less than 1 cm) seem to have a lower risk of malignant transformation than do larger polyps and are less likely to be malignant or to have high-grade histologic features. With increasing data, it appears that there is a low prevalence of histologically advanced polyps in the proximal colon among patients with small distal tubular adenomas. Wallace and associates conducted a study to determine the prevalence of advanced adenomatous polyps in the proximal colon among patients with small tubular adenomas found on flexible ...

The purpose of this paper was to investigate the effect of radiologist experience and increasing exposure to CT colonography on reader performance. Three radiologists of differing general experience (consultant, research fellow, trainee) independently analysed 100 CT colonographic datasets. Readers had no prior experience of CT colonography and received feedback and training after the first 50 cases from an independent experienced radiologist. Diagnostic performance and reporting times were compared for the first and second 50 datasets and compared with the results of a radiologist experienced in CT colonography. Before training only the consultant reader achieved statistical equivalence with the reference standard for detection of larger polyps. After training, detection rates ranged between 25 and 58% for larger polyps. Only the trainee significantly improved after training ( P=0.007), with performance of other readers unchanged or even worse. Reporting times following training were reduced ...
My mother is 54 yrs old & suffering from |b|multiple polyps in the large intestine|/b|. It was detected around 1 year back when the colonscopy was done. It was suggested by the doctors that the large intestine should be surgically removed. The polyps were tested through biopsy for malignancy, & they were found non-malignant. However, we did not go for the surgery. As of now the situation is that her haemoglobin level is around 9. She can sometimes notice fresh blood in the stools & the occult blood is always present. She has lost almost 15 kg weight in last 1 year. Now since the tests like colonscopy are very painful we cannot repeat it frequently. Can you suggest any other tests etc as to know about the malignancy in the polyps? Can blood tests reveal that? Can MRI tell about the polyps turning into cancer? Please suggest the how frequently tests like colonscopy be done to know about the malignancy? If a polyp tests negative once in the first colonoscopy, how do we keep a check on the development of
The study included 364 individuals (197 women and 167 men) in whom colorectal polyps were detected based on the lower gastrointestinal tract endoscopy and histopathological examination. Depending on a number of the lesions, the participants were divided into two groups: A) with one polyp (n = 177), and B) with at least two polyps (n = 187). Waist circumference was determined in all the subjects, and the results were subjected to statistical analysis. ...

Patients with SPS are at high risk of developing colorectal cancer and need expert surveillance or surgery.. The US Multi-Society Task Force on colorectal cancer now recommends yearly surveillance in SPS, but 3-6 monthly procedures may be required to control the polyps initially. A possible algorithm of clinical and endoscopic management in SPS has recently been proposed.. Colonoscopy must be meticulous as SSA/P are hard to see and can grow rapidly. Enhanced imaging techniques such as chromendoscopy or narrow band imaging may be helpful. Hyperplastic polyps ,5mm can be noted but left alone. All lesions ,5mm diameter should be removed.. There will be some patients with SPS whose polyps are not adequately controlled by colonoscopy and polypectomy. In this situation surgery is the best management option and generally, because of the pancolonic location of the polyps, this involves colectomy and ileo-rectal anastomosis.. There is controversy as to whether first degree relatives of patients with SPS ...

Mechanics of a Colonoscopy. During a colonoscopy, a GI doctor inserts a flexible tube called a colonoscope into the rectum and extends it to the farthest point in the large intestine known as the cecum. The colonoscope is equipped with a tiny camera that transmits live video to a monitor. As the tube is withdrawn, the doctor examines the colon wall for adenomas and removes suspicious growths.. Adenoma detection rate (ADR) is the primary indicator of the quality of a colonoscopy procedure because adenoma removal is associated with decreased colon cancer risk. Therefore, any method or device that enhances a physicians ability to detect polyps or lesions has the potential to lower colon cancer incidence.. The Endocuff was designed to smooth out folds in the colon wall and help maintain colonoscope stability during withdrawal. Another quality measure of an effective colonoscopy is withdrawal time, the number of minutes it takes for a physician to view the colon from cecum to rectum. The Endocuff ...

Polyps are common benign growths. They can occur in the uterus (endometrial polyps), cervix (cervical polyps) or vagina (vaginal polyps). Polyps can be isolated, but sometimes multiple polyps are apparent.. The chances of a cancer being present in a polyp is low. Older women are more at risk than younger women.. ...
The mononuclear leukocytes from peripheral blood samples of individuals with (n = 30) and without (n = 48) colonic polyps were examined for their abilities to carry out unscheduled DNA synthesis (UDS) induced by N-acetoxy-N-2-fluorenylacetamide (N-AcO-2-FAA). Individuals with polyps had significantly reduced UDS values compared to the nonpolyp group (P , 0.01). Furthermore, in a more comprehensive study, patients with hyperplastic polyps had N-AcO-2-FAA-induced UDS values not significantly different from control individuals who were asymptomatic and free from colonic disease as judged by complete colonoscopy. However, patients who had had adenomatous polyps in their large bowel had significantly reduced levels of N-AcO-2-FAA-induced UDS in their mononuclear leukocytes (P , 0.005). When N-AcO-2-FAA binding to DNA determinations were made in parallel and DNA repair proficiency indices were calculated (i.e., N-AcO-2-FAA-induced UDS/N-AcO-2-FAA binding to DNA), the patients with adenomatous polyps ...

Recent studies at Mayo Clinics campus in Florida suggest these benchmarks may be too low.. Their study, in the online issue of Gastrointestinal Endoscopy, found that use of high-definition imaging tools in 2,400 individuals undergoing a screening colonoscopy at the clinic led to an adenoma detection rate (ADR) of 25 percent in women and 41 percent in men. Current national guidelines set the benchmark ADR at 15 percent in women and 25 percent in men for individuals at average risk of colorectal cancer - those without a family history or symptoms of the cancer.. Adenomas are potentially precancerous polyps, and ADR is defined as the percentage of screened patients with at least one adenoma detected. So, a 15 percent ADR in women means 15 of 100 women screened were found to have at least one potentially precancerous polyp.. "Our study suggests that national benchmarks may be too low given our increasing ability to find polyps using the high-definition colonoscopy tools that a majority of ...
I am 71 years old. Several years back a barium X-ray revealed that I had |b|multiple pouches in the large intestine|/b|. Colonoscopy revealed a small polyp (biopsy negative) and smeared out. Two years back another colonoscopy was done but showed no sign of polyp recurrence but the number of pouches had increased. I get occasional intestinal pain (localised lower right side, almost at the appendix area). Fibre food is my priority and therefore normal bowel movement. The pain is not severe, but moderate and irregular. No occult blood in stools. Is the pain related to diverticulosis especially when there is no sign of micro-perforations on any of the pouches (diverticula), nor are there any abnormalities in liver, spleen, kidney and stomach as per recent detailed tests.

This procedure allows us to directly examine the mucosa (lining) of the rectum, colon and terminal ileum (final part of the small intestine). These are common locations of many important gastrointestinal diseases such as colorectal cancer, colonic polyps, diverticular disease and inflammatory bowel disease (Crohns disease and ulcerative colitis).. Colonoscopy requires the bowel to be cleared to provide us with the best possible views of the mucosa and is performed under sedation. During colonoscopy, we are able to diagnose abnormalities by direct inspection and confirm the findings by biopsy and microscopic examination. Additionally, we are also able to treat some abnormalities such as polyps by removing them, thus reducing the subsequent risk of bowel cancer...

A small study suggests that serrated adenoma may be a form of familial adenomatous polyposis (FAP) and not a separate type of colorectal cancer.. Three serrated adenomas were found separately in three out of 11 Japanese patients from three families with FAP. Colorectal polyps numbered ,100 in each of the three, and all serrated adenomas were found in the rectum. All three patients with serrated adenomas had mutations in the adenomatous polyposis coli (APC) gene-two proximal to the site of the gene, at codon 161, 332 and the third at the most distal site, codon 1556. Mutations in the other patients were located between codons 554 and 1324.. The rate of occurrence of serrated adenoma in the study was 30 times that in the general population so APC mutation may influence pathogenesis of serrated adenoma. The genetic results are compatible with a recent report describing colonic polyposis of ,100 polyps as attenuated FAP, so serrated adenoma may actually be a phenotype of FAP.. All 11 patients had a ...
Gallbladder polyps are growths or lesions resembling growths (polypoid lesions) in the wall of the gallbladder. True polyps are abnormal accumulations of mucous membrane tissue that would normally be shed by the body. The main types of polypoid growths of the gallbladder include cholesterol polyp/cholesterosis, cholesterosis with fibrous dysplasia of gallbladder, adenomyomatosis, hyperplastic cholecystosis, and adenocarcinoma.[citation needed] Most polyps do not cause noticeable symptoms. Gallbladder polyps are usually found incidentally when examining the abdomen by ultrasound for other conditions, usually abdominal pain.[citation needed] Most small polyps (less than 1 cm) are not cancerous and may remain unchanged for years. However, when small polyps occur with other conditions, such as primary sclerosing cholangitis, they are less likely to be benign. Larger polyps are more likely to develop into adenocarcinomas.[citation needed] Cholesterolosis is characterized by an outgrowth of the ...
Familial adenomatous polyposis (FAP) is caused by pathogenic variants in the APC gene resulting in the development of hundreds to thousands of adenomatous colonic polyps beginning in early adolescence. The lifetime risk for cancer in individuals with FAP is 100 percent. Additional symptoms may include dental anomalies, polyps of the gastric fundus and duodenum, and congenital hypertrophy of the retinal pigment epithelium (CHRPE). Pathogenic APC variants may also cause other related syndromes, including attenuated FAP (AFAP), gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS), Gardner syndrome, and Turcot syndrome.. MUTYH-associated polyposis (MAP), caused by biallelic pathogenic variants in the MUTYH gene, can result in the development of colon polyps that are less numerous (typically 10-100) and is often diagnosed later in life. Genetic testing may be used to assess individuals at risk for FAP, other APC-associated polyposis, or MAP due to a suggestive personal or family ...
OBJECTIVE: The purpose of this study was to evaluate the effectiveness of CT colonography (CTC) as a triage technique in faecal occult blood test (FOBT)-positive screening participants. METHODS: Consecutive guaiac (G-FOBT) and immunochemical (I-FOBT) FOBT-positive patients scheduled for colonoscopy underwent CTC with iodine tagging bowel preparation. Each CTC was read independently by two experienced observers. Per patient sensitivity, specificity and positive and negative predictive values (PPV and NPV) were calculated based on double reading with different CTC cut-off lesion sizes using segmental unblinded colonoscopy as the reference standard. The acceptability of the technique to patients was evaluated with questionnaires. RESULTS: 302 FOBT-positive patients were included (54 G-FOBT and 248 I-FOBT). 22 FOBT-positive patients (7%) had a colorectal carcinoma and 211 (70%) had a lesion ,or=6 mm. Participants considered colonoscopy more burdensome than CTC (p,0.05). Using a 6 mm CTC size ...
A flexible sigmoidoscopy can help your doctor determine the cause of abdominal pain, rectal bleeding, changes in bowel habits, chronic diarrhea and other intestinal problems. Your doctor may be able to diagnose the cause of diarrhea, bowel obstruction, diverticulosis, inflammatory bowel disease, anal fissures and hemorrhoids, as well as find colon polyps that might be in this lower part of the colon. Flexible sigmoidoscopy does not allow the doctor to see the entire colon. Therefore, any cancers or polyps farther into the colon cannot be detected with flexible sigmoidoscopy. A colonoscopy allows the doctor to examine the entire colon. Preparing for Flexible Sigmoidoscopy The lower colon and rectum must be completely empty for a flexible sigmoidoscopy to be thorough and safe. Some doctors recommend a combination of a laxative and a small enema before the test. Some doctors may advise the patient to drink only clear liquids for 12 to 24 hours before the procedure is scheduled. A liquid diet means ...

ISSN 2078-5151.. BACKGROUD: Hereditary mixed polyposis syndrome is characterised by multiple large-bowel polyps of differing histological types including a mixture of atypical juvenile polyps, hyperplastic polyps and adenomas. Affected individuals are thought to have an increased risk of malignancy, possibly via the juvenile polyposis pathway. METHODS: A 51-year-old woman (with a history of a colectomy for polyps during childhood) presented with rectal bleeding. Endoscopy demonstrated small rectal polyps which were hyperplastic on histology. A family tree was drawn up and the three children of the proband underwent flexible sigmoidoscopy. RESULTS: Endoscopic surveillance of the three children revealed one who had a similar phenotype to the mother. This child underwent colectomy and ileorectal anastomosis. ...
The latter two groups commonly present with abdominal pain, weakness, rectal bleeding, diarrhea, or rectal prolapse. Laboratory findings include anemia, hypoalbuminemia, hypokalemia, and skin test anergy. Juvenile polyposis is a premalignant condition with changes seen in children as young as 3 years of age. Patients with generalized involvement require surgical intervention. Subtotal colectomy and ileoproctostomy are the procedures of choice. Patients with a small number of polyps may choose instead to undergo periodic colonoscopy with colonoscopic polypectomy. Approximately 10 to 20% of affected patients have extracolonic abnormalities. These include finger clubbing and hypertrophic pulmonary osteoarthropathy related to pulmonary arteriovenous fistulas. Congenital cardiac defects, macrocephaly, cleft lip/palate, extra teeth, arteriovenous malformations of the skin, gut malrotation, psoriasis, and genitourinary abnormalities have been described. ...
