Similar outcome after colonic pouch and side-to-end anastomosis in low anterior resection for rectal cancer: a prospective randomized trial. (1/75)
OBJECTIVES: To compare a colonic J-pouch or a side-to-end anastomosis after low-anterior resection for rectal cancer with regard to functional and surgical outcome. SUMMARY BACKGROUND DATA: A complication after restorative rectal surgery with a straight anastomosis is low-anterior resection syndrome with a postoperatively deteriorated anorectal function. The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. An alternative method is to use a simple side-to-end anastomosis. METHODS: One-hundred patients with rectal cancer undergoing total mesorectal excision and colo-anal anastomosis were randomized to receive either a colonic pouch or a side-to-end anastomosis using the descending colon. Surgical results and complications were recorded. Patients were followed with a functional evaluation at 6 and 12 months postoperatively. RESULTS: Fifty patients were randomized to each group. Patient characteristics in both groups were very similar regarding age, gender, tumor level, and Dukes' stages. A large proportion of the patients received short-term preoperative radiotherapy (78%). There was no significant difference in surgical outcome between the 2 techniques with respect to anastomotic height (4 cm), perioperative blood loss (500 ml), hospital stay (11 days), postoperative complications, reoperations or pelvic sepsis rates. Comparing functional results in the 2 study groups, only the ability to evacuate the bowel in <15 minutes at 6 months reached a significant difference in favor of the pouch procedure. CONCLUSIONS: The data from this study show that either a colonic J-pouch or a side-to-end anastomosis performed on the descending colon in low-anterior resection with total mesorectal excision are methods that can be used with similar expected functional and surgical results. (+info)Long-term functional results after ileal pouch anal restorative proctocolectomy for ulcerative colitis: a prospective observational study. (2/75)
OBJECTIVE: To document functional results in patients treated with an ileal pouch anal anastomosis (IPAA). SUMMARY BACKGROUND DATA: The restorative proctocolectomy with IPAA has become the procedure of choice for patients with ulcerative colitis, yet the long-term functional results are not well known. METHODS: We performed this prospective observational study in 391 consecutive patients (56% male; mean age, 33.7 +/- 10.8 years; range, 12-66 years) who underwent an IPAA between 1987 and 2002 (mean follow-up, 33.6 months; range, 0 to 180 months). RESULTS: The majority of patients underwent the procedure under elective circumstances with a hand-sewn ileal pouch anal anastomosis and a protective ileostomy. In 25 patients (6.4%), the procedure was performed under urgent conditions; in 137 patients (35%), the temporary ileostomy was omitted; in 117 patients (29.9%), the ileal pouch anal anastomosis was stapled. There was 1 hospital mortality (0.25%) and 1 30-day mortality. Mean length of stay was 9.2 +/- 5.6 days (3-68 days; median, 8 days) and was increased by the occurrence of septic complications (8.9 versus 13.6 days; P < 0.02) and by the omission of a temporary ileostomy (8.3 versus 10.4 days; P = 0.005). Complications included pelvic abscess (1.3%), anastomotic dehiscence (6.4%), bowel obstruction (11.7%), and anastomotic stenosis in need of mechanical dilatation (10.7%). Patients were asked to record their functional results on a questionnaire for 1 week at 3, 6, 9, 12, 18, and 24 months after the IPAA and yearly thereafter. Our data to 10 years show that median number of bowel movements (bms) was 6 bm/24 hours at all time intervals. The average number of bms increased by 0.3 bm/decade of life (P < 0.001). Throughout the entire follow-up, more than 75% of patients had at least 1 bm most nights, although fewer than 40% found it necessary to alter the time of their meals to avoid bms at inappropriate times. Depending on the time interval, between 57% and 78% of patients were always able to postpone a bm until convenient, and this ability was similar in patients with a stapled or hand-sewn ileoanal anastomosis; only up to 18% were able to always distinguish between flatus and stools, and this ability was similar in patients with a stapled or hand-sewn ileoanal anastomosis. Complete daytime and nighttime continence was achieved by 53-76% of patients depending on the time interval. The percentage of fully continent patients was higher following the stapled rather than the hand-sewn technique (P < 0.001), and this difference persisted over time. When patients experienced incontinence, its occurrence ameliorated over time (P < 0.001), and the occurrence of perianal rash and itching as well as the use of protective pads decreased over time (P < 0.008). At 5 years, patients judged quality of life as much better or better in 81.4% and overall satisfaction and overall adjustment as excellent or good in 96.3% and 97.5%, respectively. CONCLUSIONS: We conclude that the IPAA confers a good quality of life. The majority of patients are fully continent, have 6 bms/d on average, and can defer a bm until convenient. When present, incontinence improves over time. (+info)Training in trauma surgery: quantitative and qualitative aspects of a new paradigm for fellowship. (3/75)
OBJECTIVE: To describe outcomes from a clinical trauma surgical education program that places the board-eligible/board-certified fellow in the role of the attending surgeon (fellow-in-exception [FIE]) during the latter half of a 2-year trauma/surgical critical care fellowship. SUMMARY BACKGROUND DATA: National discussions have begun to explore the question of optimal methods for postresidency training in surgery. Few objective studies are available to evaluate current training models. METHODS: We analyzed provider-specific data from both our trauma registry and performance improvement (PI) databases. In addition, we performed TRISS analysis when all data were available. Registry and PI data were analyzed as 2 groups (faculty trauma surgeons and FIEs) to determine experience, safety, and trends in errors. We also surveyed graduate fellows using a questionnaire that evaluated perceptions of training and experience on a 6-point Likert scale. RESULTS: During a 4-year period 7,769 trauma patients were evaluated, of which 46.3% met criteria to be submitted to the PA Trauma Outcome Study (PTOS, ie, more severe injury). The faculty group saw 5,885 patients (2,720 PTOS); the FIE group saw 1,884 patients (879 PTOS). The groups were similar in respect to mechanism of injury (74% blunt; 26% penetrating both groups) and injury severity (mean ISS faculty 10.0; FIEs 9.5). When indexed to patient contacts, FIEs did more operations than the faculty group (28.4% versus 25.6%; P < 0.05). Death rates were similar between groups (faculty 10.5%; FIEs 10.0%). Analysis of deaths using PI and TRISS data failed to demonstrate differences between the groups. Analysis of provider-specific errors demonstrated a slightly higher rate for FIEs when compared with faculty when indexed to PTOS cases (4.1% versus 2.1%; P < 0.01). For both groups, errors in management were more common than errors in technique. Twenty-one (91%) of twenty-three surveys were returned. Fellows' feelings of preparedness to manage complex trauma patients improved during the fellowship (mean 3.2 prior to fellowship versus 4.5 after first year versus 5.8 after FIE year; P < 0.05 by ANOVA). Eighty percent rated the FIE educational experience "great -5" or "exceptional- 6." Eighty-five percent consider the current structure of the fellowship (with FIE year) as ideal. Ninety percent would repeat the fellowship. CONCLUSION: The educational experience and training improvement offered by the inclusion of a FIE period during a trauma fellowship is exceptional. Patient outcomes are unchanged. The potential for an increased error rate is present during this period of clinical autonomy and must be addressed when designing the methods of supervision of care to assure concurrent senior staff review. (+info)Quantification of risk for pouch failure after ileal pouch anal anastomosis surgery. (4/75)
OBJECTIVE: To identify risk factors associated with ileal pouch failure and to develop a multifactorial model for quantifying the risk of failure in individual patients. SUMMARY BACKGROUND DATA Ileal pouch anal anastomosis (IPAA) has become the treatment choice for most patients with ulcerative colitis and familial adenomatous polyposis who require surgery. At present, there are no published studies that investigate collectively the interrelation of factors related to ileal pouch failure, nor are there any predictive indices for risk stratification of patients undergoing IPAA surgery. METHODS: Data from 23 preoperative, 7 intraoperative, and 10 postoperative risk factors were recorded from 1,965 patients undergoing restorative proctocolectomy in a single center between 1983 and 2001. Primary end point was ileal pouch failure during the follow-up period of up to 19 years. The "CCF ileal pouch failure" model was developed using a parametric survival analysis and a 70%:30% split-sample validation technique for model training and testing. RESULTS: The median patient follow-up was 4.1 year (range, 0-19 years). Five-year ileal pouch survival was 95.6% (95% CI, 94.4-96.7). The following risk factors were found to be independent predictors of pouch survival and were used in the final multivariate model: patient diagnosis, prior anal pathology, abnormal anal manometry, patient comorbidity, pouch-perineal or pouch-vaginal fistulae, pelvic sepsis, anastomotic stricture and separation. The model accurately predicted the risk of ileal pouch failure with adequate calibration statistics (Hosmer Lemeshow chi2 = 3.001; P = 0.557) and an area under the receiver operating characteristics curve of 82.0%. CONCLUSIONS: The CCF ileal pouch failure model is a simple and accurate way of predicting the risk of ileal pouch failure in clinical practice on a longitudinal basis. It may play an important role in providing risk estimates for patients wishing to make informed choices on the type of treatment offered to them. (+info)Short- and long-term outcomes of ileal pouch-anal anastomosis for ulcerative colitis. (5/75)
Ileal pouch-anal anastomosis was an important advancement in the treatment of ulcerative colitis. The aim of this study was to determine whether early complications of ileal pouch-anal anastomosis in patients with ulcerative colitis are associated with poor late functional results. PATIENTS AND METHODS: Eighty patients were operated on from 1986 to 2000, 62 patients with ileostomy and 18 without. The early and late complications were recorded. Specific emphasis has been placed on the incidence of pouchitis with prolonged follow-up. RESULTS: The ileostomy was closed an average of 9.2 months after the first operation. Fourteen patients were excluded from the long-term evaluation; 6 patients were lost to regular follow-up, 4 died, and 4 patients still have the ileostomy. Of the 4 patients that died, 1 died from surgical complications. Early complications after operation (41) occurred in 34 patients (42.5%). Late complications (29) occurred in 25 patients as follows: 16 had pouchitis, 3 associated with stenosis and 1 with sexual dysfunction; 5 had stenosis; and there was 1 case each of incisional hernia, ileoanal fistula, hepatic cancer, and endometriosis. Pouchitis occurred in 6 patients (9.8%) 1 year after ileal pouch-anal anastomosis, 9 (14.8%) after 3 years, 13 (21.3%) after 5 years, and 16 (26.2%) after more than 6 years. The mean daily stool frequency was 12 before and 5.8 after operation. One pouch was removed because of fistulas that appeared 2 years later. CONCLUSIONS: Ileal pouch-anal anastomosis is associated with a considerable number of early complications. There was no correlation between pouchitis and severe disease, operation with or without ileostomy, or early postoperative complications. The incidence of pouchitis was directly proportional to duration of time of follow-up. (+info)Could laparoscopic colon and rectal surgery become the standard of care? A review and experience with 750 procedures. (6/75)
INTRODUCTION: The benefits of the laparoscopic approach to colon and rectal surgery do not seem as great as for other laparoscopic procedures. To study this further we decided to review the current literature and the 10-year experience of a surgical group from university teaching hospitals in Montreal, Quebec and Toronto in performing laparoscopic colon and rectal surgery. METHODS: The prospectively designed case series comprised all patients having laparoscopic colon and rectal surgery. The procedures were carried out by a group of 4 surgeons between April 1991 and November 2001. We noted intraoperative complications, any conversions to open surgery, operating time, postoperative complications and postoperative length of hospital stay. RESULTS: The group attempted 750 laparoscopic colon and rectal procedures of which 669 were completed laparoscopically. Malignant disease was the indication for surgery in 49.6% of cases. Right hemicolectomy and sigmoid colectomy accounted for 54.5% of procedures performed. Intraoperative complications occurred in 8.3%, with 29.0% of these resulting in conversion to open surgery. The overall rate of conversion to open surgery was 10.8%, most commonly for oncologic concerns. Median operating time was 175 minutes for all procedures. Postoperative complications occurred in 27.5% of procedures completed laparoscopically but were mostly minor wound complications. Pulmonary complications occurred in only 1.0%. The anastomotic leak rate was 2.5%. The early reoperation rate was 2.4%. Postoperative mortality was 2.2%. No port site metastases have yet been detected. The median postoperative length of stay was 5 days. CONCLUSIONS: The clinical outcomes of laparoscopic colon and rectal surgery in this 10-year experience are consistent with numerous cohort studies and randomized clinical trials. Laparoscopic colon and rectal surgery in the hands of well-trained surgeons can be performed safely with short hospital stay, low analgesic requirements and acceptable complication rates compared with historical controls and other reports in the literature. Evidence from published randomized clinical trials is emerging that under these conditions laparoscopic resection represents the better treatment option for most benign conditions, but concerns regarding its appropriateness for malignant disease are still to be resolved. (+info)Continent diversions: the new gold standards of ileoanal reservoir and neobladder. (7/75)
In recent decades, surgical treatment of familial adenomatous polyposis, chronic ulcerative colitis, and muscle-invasive bladder cancer has undergone a revolution. Specifically, ileoanal reservoir and neobladder have become the new "gold standard" of definitive surgical therapy for these disorders. This article discusses issues in surgical construction, indications, contraindications, perioperative care concepts, and nursing and health professional implications related to these two procedures. These interventions include screening candidates for ileoanal reservoir or neobladder to rule out Crohn's disease or metastatic cancer and educating candidates for continent diversions about the proposed procedure(s) and associated events, potential complications, postoperative exercise, sexual health and function issues, and the benefits of support group participation so they can gain a realistic understanding of ultimate functional outcomes. Questions for future research are addressed. (+info)The effect of ageing on function and quality of life in ileal pouch patients: a single cohort experience of 409 patients with chronic ulcerative colitis. (8/75)
OBJECTIVE: To evaluate in what manner ageing affects functional outcome and quality of life (QoL) in patients with chronic ulcerative colitis (CUC) after ileal pouch-anal anastomosis (IPAA). SUMMARY BACKGROUND DATA: Short-term function and QoL after IPAA is good. However, patients are usually young, and little is known about the influence of time and ageing on long-term outcomes after IPAA. METHODS: Using a standardized questionnaire, functional outcome, QoL, and complications were assessed prospectively in a cohort of 409 patients followed annually for 15 years after IPAA. RESULTS: Follow-up was complete in the single cohort of 409 patients and functional and QoL outcomes summarized at 5, 10, and 15 years. Daytime stool frequency changed little (mean 6), while nighttime frequency increased from 1 stool to 2 stools. Incontinence for gas and stool increased from 1% to 10% during the day and from 2% to 24% at night over 15 years. The cumulative probability of pouchitis increased from 28% at 5 years to 38% at 10 years and to 47% at 15 years. Bowel obstruction and stricture were other principal long-term complications. At 15 years, 91% of patients had kept the same job. Work was not affected by the surgery in 83%, while social activities, sports, traveling, and sexual life all improved after surgery and did not deteriorate over time. CONCLUSIONS: These long-term results in a single cohort of 409 IPAA patients are unique and are likely a more accurate reflection of long-term outcome than has been previously reported. These data support the conclusion that IPAA is a durable operation for patients requiring proctocolectomy for CUC; functional and QoL outcomes are good, predictable, and stable for 15 years after operation. (+info)1. Ulcerative colitis: This is a chronic condition that causes inflammation and ulcers in the colon. Symptoms can include abdominal pain, diarrhea, and rectal bleeding.
2. Crohn's disease: This is a chronic condition that affects the digestive tract, including the colon. Symptoms can include abdominal pain, diarrhea, fatigue, and weight loss.
3. Irritable bowel syndrome (IBS): This is a common condition characterized by recurring abdominal pain, bloating, and changes in bowel movements.
4. Diverticulitis: This is a condition where small pouches form in the colon and become inflamed. Symptoms can include fever, abdominal pain, and changes in bowel movements.
5. Colon cancer: This is a type of cancer that affects the colon. Symptoms can include blood in the stool, changes in bowel movements, and abdominal pain.
6. Inflammatory bowel disease (IBD): This is a group of chronic conditions that cause inflammation in the digestive tract, including the colon. Symptoms can include abdominal pain, diarrhea, fatigue, and weight loss.
7. Rectal cancer: This is a type of cancer that affects the rectum, which is the final portion of the colon. Symptoms can include blood in the stool, changes in bowel movements, and abdominal pain.
8. Anal fissures: These are small tears in the skin around the anus that can cause pain and bleeding.
9. Rectal prolapse: This is a condition where the rectum protrudes through the anus. Symptoms can include rectal bleeding, pain during bowel movements, and a feeling of fullness or pressure in the rectal area.
10. Hemorrhoids: These are swollen veins in the rectum or anus that can cause pain, itching, and bleeding.
It's important to note that some of these conditions can be caused by other factors as well, so if you're experiencing any of these symptoms, it's important to see a doctor for an accurate diagnosis and treatment.
There are several types of colonic neoplasms, including:
1. Adenomas: These are benign growths that are usually precursors to colorectal cancer.
2. Carcinomas: These are malignant tumors that arise from the epithelial lining of the colon.
3. Sarcomas: These are rare malignant tumors that arise from the connective tissue of the colon.
4. Lymphomas: These are cancers of the immune system that can affect the colon.
Colonic neoplasms can cause a variety of symptoms, including bleeding, abdominal pain, and changes in bowel habits. They are often diagnosed through a combination of medical imaging tests (such as colonoscopy or CT scan) and biopsy. Treatment for colonic neoplasms depends on the type and stage of the tumor, and may include surgery, chemotherapy, and/or radiation therapy.
Overall, colonic neoplasms are a common condition that can have serious consequences if left untreated. It is important for individuals to be aware of their risk factors and to undergo regular screening for colon cancer to help detect and treat any abnormal growths or tumors in the colon.
Symptoms of Pouchitis:
* Diarrhea
* Abdominal pain
* Fever
* Nausea and vomiting
* Blood in stool
Treatment of Pouchitis:
* Antibiotics to treat any underlying infections
* Increased fluid and electrolyte intake to prevent dehydration
* Use of anti-inflammatory medications such as mesalamine or corticosteroids to reduce inflammation
* In severe cases, surgical intervention may be necessary to remove the pouch and replace it with a colostomy bag.
Prevention of Pouchitis:
* Proper care and maintenance of the pouch, including regular cleaning and drying
* Avoiding use of harsh soaps or chemicals near the pouch
* Avoiding insertion of any foreign objects into the pouch
* Following a balanced diet and avoiding spicy or fatty foods that can irritate the pouch.
The exact cause of colonic polyps is not fully understood, but they are thought to be related to inflammation, genetic mutations, and abnormal cell growth. Some risk factors for developing colonic polyps include:
1. Age (they become more common with age)
2. Family history of colon cancer or polyps
3. Inflammatory bowel disease (such as ulcerative colitis or Crohn's disease)
4. Previous history of colon cancer or polyps
5. A diet high in fat and low in fiber
6. Obesity
7. Lack of physical activity
There are several types of colonic polyps, including:
1. Adenomatous polyps: These are the most common type of polyp and have the potential to become malignant (cancerous) over time if left untreated.
2. Hyperplastic polyps: These are benign growths that are usually small and have a smooth surface.
3. Inflammatory polyps: These are associated with inflammation in the colon and are usually benign.
4. Villous adenomas: These are precancerous growths that can develop into colon cancer if left untreated.
Colonic polyps do not always cause symptoms, but they can sometimes cause:
1. Blood in the stool
2. Changes in bowel movements (such as diarrhea or constipation)
3. Abdominal pain or discomfort
4. Weakness and fatigue
If colonic polyps are suspected, a doctor may perform several tests to confirm the diagnosis, including:
1. Colonoscopy: A flexible tube with a camera and light on the end is inserted through the rectum and into the colon to visualize the inside of the colon and look for polyps.
2. Fecal occult blood test (FOBT): This test detects small amounts of blood in the stool.
3. Barium enema: A barium solution is inserted into the rectum and x-rays are taken to visualize the inside of the colon.
4. CT colonography (virtual colonoscopy): This test uses a CT scan to create detailed images of the colon and detect polyps.
If colonic polyps are found, they may be removed during a colonoscopy procedure. The type of treatment will depend on the size, location, and number of polyps, as well as the patient's overall health. Polyps that are small and few in number may be removed by snare polypectomy, where a thin wire loop is used to remove the polyp. Larger polyps or those that are more numerous may require surgical removal of a portion of the colon.
It is important for individuals to be screened for colonic polyps regularly, as they can potentially develop into colon cancer if left untreated. The American Cancer Society recommends that individuals with an average risk of colon cancer begin screening at age 50 and continue every 5 years until age 75. Individuals with a higher risk, such as those with a family history of colon cancer or a personal history of inflammatory bowel disease, may need to begin screening earlier and more frequently.
UC can be challenging to diagnose and treat, and there is no known cure. However, with proper management, it is possible for people with UC to experience long periods of remission and improve their quality of life. Treatment options include medications such as aminosalicylates, corticosteroids, and immunomodulators, as well as surgery in severe cases.
It's important for individuals with UC to work closely with their healthcare provider to develop a personalized treatment plan that takes into account their specific symptoms and needs. With the right treatment and support, many people with UC are able to manage their symptoms and lead active, fulfilling lives.
The most common type of colitis is ulcerative colitis, which affects the rectum and lower part of the colon. The symptoms of ulcerative colitis can include:
* Diarrhea (which may be bloody)
* Abdominal pain and cramping
* Rectal bleeding
* Weight loss
* Fever
* Loss of appetite
* Nausea and vomiting
Microscopic colitis is another type of colitis that is characterized by inflammation in the colon, but without visible ulcers or bleeding. The symptoms of microscopic colitis are similar to those of ulcerative colitis, but may be less severe.
Other types of colitis include:
* Infantile colitis: This is a rare condition that affects babies and young children, and is characterized by diarrhea, fever, and vomiting.
* Isomorphic colitis: This is a rare condition that affects the colon and rectum, and is characterized by inflammation and symptoms similar to ulcerative colitis.
* Radiation colitis: This is a condition that occurs after radiation therapy to the pelvic area, and is characterized by inflammation and symptoms similar to ulcerative colitis.
* Ischemic colitis: This is a condition where there is a reduction in blood flow to the colon, which can lead to inflammation and symptoms such as abdominal pain and diarrhea.
The diagnosis of colitis typically involves a combination of physical examination, medical history, and diagnostic tests such as:
* Colonoscopy: This is a test that uses a flexible tube with a camera on the end to visualize the inside of the colon and rectum.
* Endoscopy: This is a test that uses a flexible tube with a camera on the end to visualize the inside of the esophagus, stomach, and duodenum.
* Stool tests: These are tests that analyze stool samples for signs of inflammation or infection.
* Blood tests: These are tests that analyze blood samples for signs of inflammation or infection.
* Biopsy: This is a test that involves taking a small sample of tissue from the colon and examining it under a microscope for signs of inflammation or infection.
Treatment for colitis depends on the underlying cause, but may include medications such as:
* Aminosalicylates: These are medications that help to reduce inflammation in the colon and relieve symptoms such as diarrhea and abdominal pain. Examples include sulfasalazine (Azulfidine) and mesalamine (Asacol).
* Corticosteroids: These are medications that help to reduce inflammation in the body. They may be used short-term to control acute flares of colitis, or long-term to maintain remission. Examples include prednisone and hydrocortisone.
* Immunomodulators: These are medications that help to suppress the immune system and reduce inflammation. Examples include azathioprine (Imuran) and mercaptopurine (Purinethol).
* Biologics: These are medications that target specific proteins involved in the inflammatory response. Examples include infliximab (Remicade) and adalimumab (Humira).
In addition to medication, lifestyle changes such as dietary modifications and stress management techniques may also be helpful in managing colitis symptoms. Surgery may be necessary in some cases where the colitis is severe or persistent, and involves removing damaged portions of the colon and rectum.
It's important to note that colitis can increase the risk of developing colon cancer, so regular screening for colon cancer is recommended for people with chronic colitis. Additionally, people with colitis may be more susceptible to other health problems such as osteoporosis, osteopenia, and liver disease, so it's important to work closely with a healthcare provider to monitor for these conditions and take steps to prevent them.
There are several possible causes of colonic pseudo-obstruction, including:
1. Inflammatory bowel disease (IBD): Both Crohn's disease and ulcerative colitis can cause colonic pseudo-obstruction due to chronic inflammation and scarring in the colon.
2. Ischemic colitis: Reduced blood flow to the colon can lead to inflammation and scarring, which can cause pseudo-obstruction.
3. Infections: Bacterial or viral infections can cause inflammation in the colon, leading to pseudo-obstruction.
4. Radiation proctitis: Radiation therapy to the pelvic area can cause inflammation and scarring in the colon, leading to pseudo-obstruction.
5. Surgical scar adhesions: Adhesions from previous abdominal surgery can cause the colon to become rigid and dilated, mimicking an obstruction.
6. Other causes: Other possible causes of colonic pseudo-obstruction include diverticulitis, appendicitis, and some medications.
The symptoms of colonic pseudo-obstruction can vary depending on the underlying cause, but may include:
1. Abdominal pain
2. Distension (enlargement) of the abdomen
3. Nausea and vomiting
4. Diarrhea or constipation
5. Fever
6. Loss of appetite
The diagnosis of colonic pseudo-obstruction is based on a combination of clinical symptoms, physical examination findings, and imaging studies such as X-rays, CT scans, or MRI. Treatment depends on the underlying cause, but may include antibiotics, bowel rest, and/or surgery.
It is common for people over the age of 50 to develop diverticulosis as a result of the natural aging process, which can cause weakening of the colon walls. This condition usually does not produce any symptoms unless the diverticula (the pouches or sacs) become inflamed or infected.
Symptoms can include:
* Abdominal pain
* Fever
* Nausea
* Vomiting
* Changes in bowel movements
* Rectal bleeding
Treatment for diverticulosis typically involves antibiotics to treat any underlying infections, and changes to the diet to help manage symptoms. In severe cases, surgery may be necessary.

- In the past, people with small pouches (diverticula) in the lining of the colon were told to avoid nuts, seeds and popcorn. (headshotsmarathon.org)
- Colonoscopy is useful for diagnosing colonic diverticula and colonic diverticular bleeding. (headshotsmarathon.org)
Colon6
- Bolsas o reservorios creados para funcionar en el lugar del COLON y/o del RECTO que se emplean en los pacientes que sufren una PROCTOCOLECTOMÍA REPARADORA. (bvsalud.org)
- Diverticulosis is a condition that occurs when small pouches, or sacs, form and push outward through weak spots in the wall of your colon . (nih.gov)
- These pouches form mostly in the lower part of your colon, called the sigmoid colon . (nih.gov)
- Background: Congenital Pouch colon(CPC) is a rare variant of anorectal malformations (ARM) whose etiopathogenesis and management are not yet standardized. (who.int)
- The excised pouch from the neonates with CPC and a strip of sigmoid colon from other high ARM patients were sent for biopsy and the histopathological features compared. (who.int)
- The statistically significant histopathological differences in the colonic pouch as compared to normal sigmoid colon were mucosal necrosis, focal erosions, inflammation and haemorrhage, muscularis mucosa fibrosis, submucosal congestion and haemorrhage, widening, fibrosis and presence of lymphoid follicles and circular and longitudinal muscle disarray and fibrosis. (who.int)
Rectal1
- Expertise in modest though relatively painless procedures for fissures and fistulas like botox and fistula plugs Interests are in Key hole surgery or colonic and rectal cancer offering patients less pain and faster recover. (mozocare.com)
Mucosa2
- The two major types of inflammatory bowel disease are ulcerative colitis (UC), which is limited to the colonic mucosa, and Crohn disease (CD), which can affect any segment of the gastrointestinal tract from the mouth to the anus, involves "skip lesions," and is transmural. (medscape.com)
- Results: Histopathogical abnormalities were seen involving all the layers of the colonic pouch including mucosa, submucosa and muscularis propria. (who.int)

Phenotype2
Diverticulosis1
- Diverticulosis is a condition in which there are small pouches or pockets in the wall or lining of any portion of the digestive tract. (headshotsmarathon.org)
Ileostomy2
- Despite normal pouchogram and EUA, four asymptomatic patients required subsequent diversion for pouch-related complications between 13 and 60 months after ileostomy reversal. (duke.edu)
- EUA and pouchogram were concordant in two patients (n = 1 anastomotic complication, n = 1 pouch septum) and ileostomy reversal was delayed. (duke.edu)
Gastric2
- Alfa-Lox not only promotes gastric health, but many horses with gastric ulcers also have colonic ulcers that cannot be. (dogfooddirect.com)
- Alfa-Lox not only promotes gastric health, but many horses with gastric ulcers also have colonic ulcers that cannot be definitively diagnosed. (dogfooddirect.com)
Restorative proctocolectomy1
- INTRODUCTION: The surgical treatment of choice in patients with ulcerative colitis (UC) is the restorative proctocolectomy with ileo-anal J pouch. (sages.org)
Tissue2
- of the pouch epithelial tissue [25]C[27]. (health-e-nc.org)
- While not a true conversion to colonic tissue, the metaplastic epithelial architecture exhibits defined changes that more closely resemble colonic tissue: a change in the crypt-villus relationship where the crypts deepen and the villi become shortened and an increase in the relative population of goblet cells (mucous producing cells) [25]C[27]. (health-e-nc.org)
Diseases1
- Treatment for colonic diseases varies greatly depending on the disease and its severity. (medlineplus.gov)
Inflammation1
- Chronic, low-level inflammation has been associated with colonic metaplasia, and has been implicated as a mechanism driving the alterations seen in the mucosal architecture [27]. (health-e-nc.org)
Diversion1
- Long term, none of these patients required diversion or excision of their pouch. (duke.edu)
Stomach2
- Great care was taken to preserve innervation of the stomach including pouches prepared for collection of stomach acid or collection of pancreatic secretions. (asmbs.org)
- Overall, food-producing animals such as pigs and chickens and companion animals (cats, dogs) have a pouch-like, noncompartmentalized stomach, whereas ruminant animals (cows, sheep) have more specialized fermenting chambers. (oregonstate.education)
Surgery1
- Trained in advanced laparoscopic pouch surgery for colitis avoiding a permanent stoma. (mozocare.com)
Condition1
- Crypt hyperplasia and villus atrophy are clearly evident (compare with normal homeostatic condition in Figure 9C, and as seen in Figure 5C), along with a villus to crypt height ratio that matches the alterations seen in colonic metaplasia [27], suggesting the plausibility of this mechanism as the driver for colonic metaplasia. (health-e-nc.org)
Effective1
- This is the same skin that is in our colons, which is why colonics are also an effective method of detox. (theprogressiveparent.org)
Diverticular disease4
- Diverticular disease (diverticulosis, diverticulitis) is a general term that refers to the presence of diverticula, small pouches in the large intestinal (colonic) wall. (medscape.com)
- Diverticular disease (diverticulosis and diverticulitis) is a general term that references the presence of diverticula, small pouches in the large intestinal (colonic) wall. (medscape.com)
- Diverticular disease can be asymptomatic (diverticulosis) or involve acute or chronic, symptomatic inflammation of these pouches (diverticulitis). (medscape.com)
- Colonic diverticular disease. (nih.gov)
Polyps3
- Classic FAP is characterized by hundreds to thousands of adenomatous colonic polyps, beginning on average at age 16 years (range 7-36 years). (nih.gov)
- The attenuated form is characterized by multiple colonic polyps (average of 30), more proximally located polyps, and a diagnosis of CRC at a later age than in classic FAP. (nih.gov)
- Resection of all colonic polyps larger than 5 mm found on colonic surveillance. (nih.gov)
Small pouches1
- Diverticulosis is a condition that occurs when small pouches, or sacs, form and push outward through weak spots in the wall of your colon . (nih.gov)
Anastomosis5
- To compare a colonic J-pouch or a side-to-end anastomosis after low-anterior resection for rectal cancer with regard to functional and surgical outcome. (medscape.com)
- One-hundred patients with rectal cancer undergoing total mesorectal excision and colo-anal anastomosis were randomized to receive either a colonic pouch or a side-to-end anastomosis using the descending colon. (medscape.com)
- The data from this study show that either a colonic J-pouch or a side-to-end anastomosis performed on the descending colon in low-anterior resection with total mesorectal excision are methods that can be used with similar expected functional and surgical results. (medscape.com)
- [ 15 , 16 ] The purpose of this prospective randomized study was to investigate functional and surgical outcome with a pouch or a nonpouch side-to-end anastomosis after standardized TME surgery for rectal cancer where only the descending colon is used. (medscape.com)
- Laparoscopic ultralow anterior resection with colonic J-pouch-anal anastomosis. (nih.gov)
Colorectal1
- Common colorectal cancer risk alleles contribute to the multiple colorectal adenoma phenotype, but do not influence colonic polyposis in FAP. (cdc.gov)
Procedure1
- 15 minutes at 6 months reached a significant difference in favor of the pouch procedure. (medscape.com)
Symptoms1
- The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. (medscape.com)
Wall1
- Diverticular bleeding occurs when a small blood vessel within the wall of a diverticulum pouch bursts. (nih.gov)
Treatment1
- Treatment for colonic diseases varies greatly depending on the disease and its severity. (medlineplus.gov)
