Inhibitory innervation of cat sphincter of Oddi. (1/430)

1 Electrical stimulation with trains of 0.1-0.2 ms pulses of the cat isolated sphincter of Oddi inhibited the spontaneous contractile activity and lowered base-line tension considerably. A contraction usually followed the period of stimulation. 2 These inhibitory effects were prevented by tetrodotoxin 0.1-0.5 mug/ml but were not reduced by hexamethonilm, morphine, or blockade of alpha- or beta-adrenoreceptors of cholinoceptors with phenoxy-benzamine propranolol or atropine, respectively. 3 Adenosine-5'-triphosphate (ATP) and adenosine-5'-diphosphate (ADP) inhibited the spontaneous sphincter activity and caused relaxation thus mimicking the effects of the C-terminal octapeptide of cholecystokinin (C8-CCK), isoprenaline and prostaglandin E1 and E2. 4 ATP alone (greater than 100 mug/ml) or ATP (greater than 10 mug/ml) plus dipyridamole (1 mug/ml), relaxed the sphincter to the same degrees as did the field stimulation. 5 In sphincter maximally contracted by acetylcholine, the effect of stimulation was more marked than that recorded in uncontracted preparations. 6 The present findings suggest that the sphincter of Oddi receives inhibitory nerves that are neither cholinergic nor adrenergic.  (+info)

Reexploration for periampullary carcinoma: resectability, perioperative results, pathology, and long-term outcome. (2/430)

OBJECTIVE: This single-institution experience retrospectively reviews the outcomes of patients undergoing reexploration for periampullary carcinoma at a high-volume center. SUMMARY BACKGROUND DATA: Many patients are referred to tertiary centers with periampullary carcinoma after their tumors were deemed unresectable at previous laparotomy. In carefully selected patients, tumor resection is often possible; however, the perioperative results and long-term outcome have not been well defined. METHODS: From November 1991 through December 1997, 78 patients who underwent previous exploratory laparotomy and/or palliative surgery for suspected periampullary carcinoma underwent reexploration. The operative outcome, resectability rate, pathology, and long-term survival rate were compared with 690 concurrent patients who had not undergone previous exploratory surgery. RESULTS: Fifty-two of the 78 patients (67%) undergoing reexploration underwent successful resection by pancreaticoduodenectomy; the remaining 26 patients (34%) were deemed to have unresectable disease. Compared with the 690 patients who had not undergone recent related surgery, the patients in the reoperative group were similar with respect to gender, race, and resectability rate but were significantly younger. The distribution of periampullary cancers by site in the reoperative group undergoing pancreaticoduodenectomy (n = 52) was 60%, 19%, 15%, and 6% for pancreatic, ampullary, distal bile duct, and duodenal tumors, respectively. These figures were similar to the 65%, 14%, 16% and 5% for resectable periampullary cancers found in the primary surgery group (n = 460). Intraoperative blood loss and transfusion requirements did not differ between the two groups. However, the mean operative time was 7.4 hours in the reoperative group, significantly longer than in the control group. On pathologic examination, reoperative patients had smaller tumors, and the percentage of patients with positive lymph nodes in the resection specimen was significantly less. The incidence of positive margins was similar between the two groups. Postoperative lengths of stay, complication rates, and perioperative mortality rates were not higher in reoperative patients. The long-term survival rate was similar between the two resected groups, with a median survival of 24 months in the reoperative group and 20 months in those without previous exploration. CONCLUSIONS: These data demonstrate that patients undergoing reoperation for periampullary carcinoma have similar resectability, perioperative morbidity and mortality, and long-term survival rates as patients undergoing initial exploration. The results suggest that selected patients considered to have unresectable disease at previous surgery should undergo restaging and reexploration at specialized high-volume centers.  (+info)

Prognostic value of MIB-1 index and DNA ploidy in resectable ampulla of Vater carcinoma. (3/430)

OBJECTIVE: To evaluate the prognostic value of the proliferative factors, MIB-1 index, DNA ploidy, and S-phase fraction, and further to determine the independent prognostic factors in ampulla of Vater carcinoma after pancreaticoduodenectomy. SUMMARY BACKGROUND DATA: Cell kinetics are important indicators of the biologic behavior of various human tumors, but only a few authors have reported the application of cell proliferative factors in ampulla of Vater carcinoma. METHODS: Patients undergoing pancreaticoduodenectomy for ampulla of Vater carcinoma were included. Proliferative factors, MIB-1 index, and DNA contents, measured by flow cytometry, were evaluated and compared with the conventional clinicopathologic factors. RESULTS: Ninety resectable ampulla of Vater carcinomas were included. By univariate analysis, MIB-1 index, DNA ploidy, S-phase fraction, stage, and lymph node status were significant prognostic factors. The 5-year survival rate was 40.7% for tumors with MIB-1 index < or =15% and 0% for those with MIB-1 index >15%. Diploid tumors had a significantly better prognosis than aneuploid. Outcomes of stage I and II tumors were more favorable than those of stage III and IV. After multivariate analysis, MIB-1 index, DNA ploidy, and stage remained as the independent prognostic factors. Among the three independent prognostic factors, MIB-1 index was the most powerful. CONCLUSIONS: Both MIB-1 index and DNA ploidy provide important prognostic value and potentially complement the conventional prognostic factors in resectable ampulla of Vater carcinoma. MIB-1 index is the most powerful independent prognostic factor.  (+info)

Pancreaticoduodenectomy with or without extended retroperitoneal lymphadenectomy for periampullary adenocarcinoma: comparison of morbidity and mortality and short-term outcome. (4/430)

OBJECTIVE: This prospective, randomized, single-institution trial was designed to evaluate the end points of mortality, morbidity, and survival in patients undergoing standard versus radical (extended) pancreaticoduodenectomy (including distal gastrectomy and retroperitoneal lymphadenectomy). SUMMARY BACKGROUND DATA: Numerous retrospective reports and one prospective randomized trial have suggested that the performance of an extended lymphadenectomy in association with a pancreaticoduodenal resection may improve long-term survival for some patients with pancreatic and other periampullary adenocarcinomas. Many of these previously published studies can be criticized for their retrospective and nonrandomized designs, for the inclusion of nonconcurrent control groups, and for their small numbers. METHODS: Between April 1996 and December 1997, 114 patients with periampullary adenocarcinoma were enrolled in an ongoing, prospective, randomized trial at The Johns Hopkins Hospital. After intraoperative verification of completely resected periampullary adenocarcinoma, the patients were randomized to receive either a standard pancreaticoduodenectomy (removing only the peripancreatic lymph nodes en bloc with the specimen) or a radical pancreaticoduodenectomy (standard resection plus distal gastrectomy and retroperitoneal lymphadenectomy). All pathology specimens were reviewed and categorized. The postoperative morbidity, mortality, and short-term outcomes were examined. RESULTS: Of the 114 patients randomized, 56 underwent a standard pancreaticoduodenectomy and 58 a radical pancreaticoduodenectomy. The two groups were statistically similar with regard to age and gender, but there was a higher percentage of white patients in the radical group. All the patients in the radical group underwent distal gastric resection, whereas 86% of the patients in the standard group underwent pylorus preservation. The mean operative time in the radical group was 6.8 hours, compared with 6.2 hours in the standard group. There were no significant differences between the two groups with respect to the intraoperative blood loss, transfusion requirements, location of primary tumor, mean tumor size, positive lymph node status, or positive margin status. There were three deaths in the standard group and two in the radical group. The complication rates were 34% for the standard group and 40% for the radical group. Patients undergoing radical resection had a higher incidence of early delayed gastric emptying but had similar rates of other complications, such as pancreatic fistula, wound infection, intraabdominal abscess, and need for reoperation. The mean total number of lymph nodes resected was higher in the radical group. Of the 58 patients in the radical group, only 10% had metastatic carcinoma in the resected retroperitoneal lymph nodes, and none of those patients had the retroperitoneal nodes as the only site of lymph node involvement. The 1-year actuarial survival rate for patients surviving the immediate postoperative periods was 77% for the standard resection group and 83% for the radical resection group. CONCLUSIONS: These data demonstrate that radical pancreaticoduodenectomy (with the addition of a distal gastrectomy and extended retroperitoneal lymphadenectomy to a standard pancreaticoduodenectomy) can be performed with similar morbidity and mortality to standard pancreaticoduodenectomy. However, the survival data are not sufficiently mature and the numbers of patients enrolled are not adequate to allow firm conclusions to be drawn regarding survival benefit.  (+info)

Bilateral ovarian carcinoma metastatic from the ampulla of Vater: a rare Krukenberg tumor. (5/430)

Carcinoma of the ampulla of Vater is a relatively rare neoplasm and its longterm survival rate is considerably high. However, because of differences in tumor pathologic features and local invasiveness, a 5-year survival rate differ widely. We present a case of metastatic carcinoma of the ampulla of Vater presenting as a Krukenberg tumor in a 59-year-old woman. Eight months earlier, she had been diagnosed as well-differentiated adenocarcinoma of the ampulla of Vater. Abdominal examination revealed a hard mass with mild tenderness in the RLQ area. The laboratory findings were unremarkable except for mild anemia. CT scan of the abdomen revealed enlargement of both ovaries. An exploratory laparotomy disclosed bilateral ovarian masses, 18 x 12 x 8 cm and 8 x 5.5 x 4 cm in size, respectively. Histologic findings of the both ovarian masses were consistent with metastatic adenocarcinoma from the ampulla of Vater.  (+info)

Obstructive jaundice and acute cholangitis due to papillary stenosis. (6/430)

Papillary stenosis is characterized by fixed fibrosis leading to structural outflow obstruction and it is usually secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. However, obstructive jaundice with or without acute cholangitis which leads the physician to suspect the presence of malignancy as a cause is a rare manifestation of papillary stenosis. We report here a case of papillary stenosis presenting with obstructive jaundice and acute cholangitis. The lesion was so difficult to exclude the presence of malignancy preoperatively and intraoperatively that a pylorus-preserving pancreaticoduodenectomy was performed. Histologic examination of the resected specimen revealed fibrosis, adenomatoid ductal hyperplasia, and mild chronic inflammation of the papilla of Vater and distal common bile duct.  (+info)

Adenoma of the ampulla of Vater: a genetic condition? (7/430)

The etiology of adenoma of the ampulla of Vater is not well understood. Previous authors reported the association of this neoplasm with polycystic kidney disease of two fraternal sisters. They concluded that these two conditions were somehow related. We describe a case of ampullary adenoma associated with polycystic kidney disease. This presentation raises again the question of a possible link between these two diseases.  (+info)

Risk of pancreatic and periampullary cancer following cholecystectomy. (8/430)

AIMS: Cholecystectomy has been reported by several investigators to increase the risk of pancreatic cancer. The trophic effect on the gland by increased release of cholecystokinin following cholecystectomy and perturbation of the neurohormonal pancreatic regulation, have been suggested as possible contributing factors. However, while several investigators found that this surgical procedure increases the risk, others have not. In an attempt to clarify whether or not patients who have undergone cholecystectomy are at increased risk for developing pancreatic cancer, we evaluated the frequency with which cholelithiasis and this surgical procedure were present in a large number of patients with pancreatic cancer. METHODS: A total of 720 patients with newly diagnosed pancreatic cancer (415 men and 305 women; mean age 62.6 years, range 22 to 79 years) and 720 controls matched for sex, age, social class, and geographic region, were enrolled in the study. All subjects were interviewed personally and in detail about their clinical history. RESULTS: Cholelithiasis was present in 126 patients with pancreatic cancer (17.5%) and in 95 controls (13.2%), constituting a statistically significant association (odds ratio, 1.39; 95% confidence interval, 1.04 to 1.86). However, considering only the patients and controls in whom the diagnosis of cholelithiasis was made for more than one year before cancer diagnosis or interview, the association was no longer significant (odds ratio, 1.04; 95% confidence interval, 0.75 to 1.44). Cholecystectomy had been performed in 93 patients with pancreatic cancer (12.9%) and in 71 controls (9.9%). When all subjects were considered, the odds ratio was mildly, although not significantly, increased (odds ratio, 1.35; 95% confidence interval, 0.97 to 1.87). When only subjects who underwent cholecystectomy one year or more before the cancer diagnosis or interview were considered, the odds ratio fell to unity (odds ratio, 1.00; 95% confidence interval, 0.70 to 1.43). CONCLUSION: This study, one of the largest on this topic, clearly shows that there is no evidence for an association between cholelithiasis, cholecystectomy, and pancreatic cancer.  (+info)

The major duodenal papilla is an opening of the Common bile duct and Pancreatic duct into the duodenum. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion. The major duodenal papilla is situated in the second part of the duodenum, 7-10 cm from the pylorus, at the level of the second or third lumbar vertebrae. It is surrounded by the sphincter of Oddi, and receives a mixture of pancreatic enzymes and bile from the Ampulla of Vater, which drains both the pancreatic duct and biliary system. The junction between the foregut and midgut occurs directly below the major duodenal papilla. The major duodenal papilla is seen from the duodenum as lying within a mucosal fold. The minor duodenal papilla is situated 2cm proximal. The major duodenal papilla is occasionally found in the third part of the duodenum, the level of the vertebrae may be L2-3, and in about 10% of people, it may not receive bile. Additionally, in a ...
Periampullary cancers encompass a mixture of cancers but in general are separated into four subtypes: cancer in the head of the pancreas, distal bile duct cancer, true ampullary cancer, and duodenal cancer. These cancers arise in the vicinity of the ampulla of Vater and are differentiated by their histologic origins (pancreatic, distal bile duct, ampulla of Vater, or duodenum). While pancreatic adenocarcinoma makes up the majority of resected periampullary cancers at 62%, ampullary cancer accounts for 19%, distal bile duct cancer 12%, and duodenal cancer 7% of resected periampullary cancers.1 Although preoperative assessment with imaging and biopsy can distinguish one subtype from the other, often times the tumor origin may be undetermined preoperatively. Moreover, duodenal cancer in the periampullary region as well as intestinal-type ampullary cancer behave in a similar fashion, whereas distal bile duct cancer and pancreaticobiliary-type ampullary cancer behave similar to one another. While 56% ...

Aims: Pancreatic adenocarcinoma is an aggressive gastrointestinal malignancy with only a few long-term survivors even after radical surgery. Patients with ampullary cancer have a better prognosis but adjuvant therapy needs further improvement. Epithelial cell adhesion molecule (Ep-CAM) is strongly expressed in a variety of epithelial cancers and represents a promising target for immunological tumour therapy. Thus, the aim of this study was to investigate Ep-CAM expression and its potential prognostic impact in pancreatic and ampullary carcinomas.. Methods: Ep-CAM expression was investigated retrospectively by immunohistochemistry in paraffin-embedded primary tumour tissue samples from a series of consecutive patients with pancreatic (n = 153) and ampullary cancer (n = 34).. Results: Ep-CAM overexpression was observed in 85 of 153 pancreatic cancer specimens (56%) and in 29 of 34 ampullary cancer samples (85%). Overall, Ep-CAM failed to be an independent prognostic marker. However, subgroup ...

Victor Maciel, MD. St. Vincent Hospital. Background: Ampullectomy is mostly performed for periampullary malignancies, however, some benign disease may benefit from ampullectomy too. Transduodenal ampullectomy requires a precise dissection and complex reconstruction. Our group has been performing robotic ampullectomies for sphincter of Oddi dyskinesia (SOD) since 2005 with good results. The introduction of robotic techniques to our practice opened the possibility of performing this technically challenging operation with a minimally invasive approach and the added benefit of articulating instruments which -we believe- result in a better intra-abdominal suturing. We studied all consecutive cases of robotic ampullectomies for SOD performed since 2005 to date (n=13). Demographics, intraoperative and postoperative complications, length of stay, blood loss and operative times were recorded. Our main goal was to discuss the robotic ampullectomy technique and to evaluate the early results of this ...
Ampullary cancer, or ampullary carcinoma, is a life-threatening cancer that forms in a body part called the ampulla of Vater in the duodenum, where the pancreatic and bile ducts release their secretions into the intestines.
We found sensitivity for the ascertainment of pancreatic and periampullary cancer cases from the hospital data of 87.5% for the 2005-2009 period. The accuracy of hospital coding varied by tumour primary site and histology, with higher sensitivity of case ascertainment for pancreatic (88.6%) and duodenal cancers (87.1%) compared with extrahepatic bile duct and ampullary cancers (78.8%) and with lower sensitivity for extrahepatic cholangiocarcinomas (67.9%). Misclassification of pancreatic and periampullary cancers in the hospital data was often to closely related sites, for example, intrahepatic bile duct carcinoma, or to less specific sites such as cancers of ill-defined or unspecified primary sites. Whereas hospital coders might only have information from a particular admission available, coders at a cancer registry often have multiple sources of information from diagnostic procedures and treatment which can enable more accurate coding of tumour characteristics.. Several aspects of the coverage ...

Recently, immunohistochemistry-based classifications of ampullary carcinomas have been proposed (Ang and colleagues [PMID: 24832159]; Chang and colleagues [PMID: 23439753]). In this study, the prognostic value of Ang/Chang panel markers (CK20, MUC1, MUC2, CDX2) as well as other markers (CK7, MUC5AC, and MUC6) were tested on full-faced sections of 136 ampullary carcinoma resections with substantial (,5 mm) invasion. Immunohistochemistry was correlated with both histologic classification (intestinal [INT], pancreatobiliary [PB], or nontubular based on ≥3/5 observer agreement) and clinical outcome. No prognostic correlation was found with MUC1, CDX2, MUC2 or CK20 despite testing with different quantitative cutoffs. CK7 and CK20 were nonspecific. Ang classification had reasonable correlation with histologic subclassification of tubular cases as INT versus PB with high specificity but low sensitivity and ambiguous category was large (29%) and included also some classical cases. Prognostically, Ang ...

Cancer of the ampulla of Vater must be differentiated from cancer of the head of the pancreas. Prognosis and potential therapeutic intervention are different. 87% of patients with carcinoma of the ampulla and 47% of those with a malignancy of the duodenum have a potentially operable tumour compared with only 22% of patients with tumours arising from the head of the pancreas [2, 12]. Therefore a noninvasive accurate technique for detection and staging is mandatory for these patients.. The endoscopic appearance of the papilla was abnormal in most of our patients. However the distinction between an impacted stone, a benign tumour or a malignancy is not always feasible. ERCP with endoscopic sphincterotomy was a helpful diagnostic procedure in cases of intraampullary tumors with a protruding papilla. In 3 cases of our patients a polypoid mass was evident only after sphincterotomy. However, ERCP is an invasive procedure with a considerable morbidity.. Moreover, endoscopic biopsies do not always allow ...

There are no specific blood tests for the diagnosis of pancreatic carcinoma. Abnormal liver function tests cannot reliably distinguish biliary obstruction (of any cause) from hepatic metastases. The most useful initial investigation seems to be abdominal ultrasonography which can identify the pancreatic tumour, as well as dilated bile ducts, and will save considerable time and inconvenience if liver metastases are identified. The reported sensitivity of ultrasonography in the detection of pancreatic carcinoma is as high at 80-95%.51-53 The technique however, becomes less sensitive in evaluating the body and tail and provides less accurate staging information than other modalities, such as CT.54,55 Technical difficulties with bowel gas compromise interpretation in 20-25% of subjects,56 and interobserver variation continues to be a problem.53 Improvements in ultrasound technology, with inclusion of colour Doppler, may improve staging accuracy, particularly with respect to vascular ...

Continuing part two of our mini-series on colorectal cancer, today we move from the big scale Immunoscore study to small subsets of disease that are looking interesting in several ways.. For years, advanced colorectal cancer has been dominated by chemotherapy (FOLFOX or FOLFIRI) with and without targeted therapies (VEGF and EGFR antibodies), with very little new to talk about. Part of the challenge here is how do you add something the existing standard of care and move the needle significantly. In front-line, for example, the OS is already out 2-plus years, so these are long and risky trials to undertake. Not surpisingly, many companies have sought to evaluate their agents in tumour types where they consider the risk of development to be lower.. Unless… we can find creative approaches that turn the paradigm on its head and identify a clearly defined niche that can be carved out separately from allcomers.. This is where were at now - identifying subsets that might respond exquisitely to novel ...
Follow-Up:. The study staff will ask about any symptoms or side effects you may be having during the 30 days after your last dose of the study drugs. The study staff may contact you by phone or at the time of a routine clinic visit. If the study staff contacts you by phone, the phone call should last about 15-30 minutes..

The minor duodenal papilla is the opening of the accessory pancreatic duct into the descending second section of the duodenum. The minor duodenal papilla is contained within the second part of the duodenum. It is situated 2 cm proximal to the major duodenal papilla, and thus 5-8 cm from the opening of the pylorus. The gastroduodenal artery lies posterior. The minor duodenal papilla may or may not contain a functioning sphincter and patent duct. When present, the sphincter is known as the sphincter of Helly, and the duct the accessory pancreatic duct of Santorini. In 10% of people, the minor duodenal papilla is the prime duct for drainage of the pancreas, although in others it may not be present at all. Pain from the region will be referred to the epigastric region of the abdomen due to its associated dermatomes.[citation needed] The duct is an embryological remnant, however in a small majority of people drains the pancreas. The minor duodenal papilla represents the remnants of the opening of the ...

Myron C Stokes, MD, Kirpal Singh, MD FACS. St. Vincent/Indiana University Fellowship of Advanced Laparoscopy, Endoscopy & Ultrasound. Ampullary neoplasms account for approximately five percent of all gastrointestinal neoplasms. Local resection of the Ampulla of Vater was first described in 1899 by Halsted. It was not until the 1980s that the first endoscopic ampullectomy was described. Thirty years later there is still no consensus statement or guidelines regarding the endoscopic management of these lesions or duodenal lesions in general. We present a 65 year old male with significant medical comorbidities that was discovered to have had an ampullary mass while undergoing endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis after an acute bout of cholecystitis managed non-operatively. Biopsies at the time of ERCP were negative for adenocarcinoma but diagnostic for high grade dysplasia. An endoscopic ultrasound (EUS) was performed and no frank invasion into the ...

Results A total of thirty-five patients were referred for papillectomy but only twenty-two patients (13 female, median age 72 years) underwent a total of 24 papillectomies. En-bloc resection was achieved in 17 patients (77%) with lesion sizes ranging from 8-25 mm (Median 16 mm). Pancreatic stent placement was successful in 82% of all papillectomies. Three patients experienced complications (12.5%); 2 bleeding and 1 acute pancreatitis. There was no procedure related deaths and no one required emergency surgery. There were no local recurrences in 77% of patients. Two patients required 2 attempts to achieve complete clearance of their adenomas. Histology of the resected lesions revealed low grade dysplasia (54.6%), high grade dysplasia (27.2%), cancer (9%), gangliocytic paraganglioma (4.6%), and neuroendocrine tumour (4.6%). Of the two patients who were found to have invasive cancer, the first patient went on to have a pancreaticoduodenectomy and subsequently died of post-operative complications ...

It has been estimated that 44,000 new cases of pancreatic cancer will be diagnosed and 37,000 deaths will occur in 2012.1 The vast majority of these patients are unresectable and consequently suffer from substantial morbidity, including obstruction of the distal bile duct. In patients with pancreatic head cancer, as well as those with other cancers that result in biliary obstruction (eg, cholangiocarcinoma and ampullary adenocarcinoma), endoscopic treatment is often successful in alleviating symptoms, reducing the risk of cholangitis, and improving biliary drainage so that hepatically metabolized chemotherapeutic agents can be used safely.2 Furthermore, over the past decade, there has been a preponderance of data suggesting that endoscopic placement of a self-expandable metal stent (SEMS) in nonresectable patients or in those whose surgical status is uncertain is cost-effective.3,4. Unfortunately, in a certain percentage of patients with malignant biliary obstruction, conventional endoscopic ...

The ampullae push into each other repeatedly, and finally the cell layers between two ampullae fuse, and results in both individuals sharing a common circulation. ...
The Whipple procedure (pancreatoduodenectomy) is the most common operation performed for pancreatic cancer and may be used to treat other cancers such as small bowel cancer. Surgeons remove the head of the pancreas, most of the duodenum (a part of the small intestine), a portion of the bile duct and sometimes a portion of the stomach. After the pancreatoduodenectomy, the surgeon reconstructs the digestive tract. (www.mayoclinic.org ...

During the one-year period, a total of 181 hospitalized patients with serum ALP level over 1000 IU/L were identified. They were 102 male and 96 female patients with ages ranging from 21 to 90 years old (mean age 49.4 ± 16.1 years). The ALP levels ranged from 1,001 to 3,067 IU/L.. The most common diagnosis in patients with high ALP in our series was malignant biliary obstruction. This was found in 58 patients, 48 of whom were cases with cholangicocarcinoma (CCA). Of the remaining 10, three were with pancreatic cancer, one with ampullary cancer, one with metastatic cancer, and five with periampullary cancer. The ALP levels ranged from 1,005 to 3,067 IU/L (average 1,869.8 ± 325.3 IU/L). In addition, benign duct obstruction from choledocholithiasis was found in another 14 patients, six of which cases were complicated by ascending cholangitis. The ALP level in this group ranged from 1,001 to 2,864 IU/L (average 1,498.3 ± 541.2 IU/L). Comparing these two groups, the mean ALP levels in the malignant ...

Abstract. Abstract Objectives: The authors present 3 cases of various pathologically confirmed malignancies (one gallbladder, one periampullary, and one liver). These patients underwent Psorinum therapy as the primary cancer treatment. Psorinum therapy is a homeopathic approach to treat patients with cancer.. Subjects: According to the American Joint Committee on Cancer tumor, nodes, metastasis system, all 3 patients were diagnosed at Stage IV. Their Karnofsky performance status was between 20% and 50% and their Eastern Cooperative Oncology Group score status was between 3 and 4. In these cases, conventional cancer treatments could not be initiated due to the advanced stage of their disease, poor general health performance status, and their financial constraints.. Interventions and outcome: In these patients, Psorinum-6x was administered orally at a dose of 0.02 mL/kg body weight/day on an empty stomach for a complete course duration of 2 years, along with allopathic and homeopathic supportive ...

In general, the symptoms of patients with congenital anomalies of the alimentary tract present early after birth with recurrent, progressive vomiting. Bilious vomiting indicates obstruction distal to the ampulla of Vater [5], which requires an immediate and correct diagnosis and surgical correction to avoid serious complications. Normally, within 3 hours of birth, the entire small bowel contains gas, whereas gas is observed in the sigmoid colon 8 to 9 hours after birth [6]. In some patients with congenital anomalies of the GI tract causing obstructions, the proximal bowel with lesions exhibits dilatation and effusion, and the distal intestinal cavity has little or no gas, thereby creating favorable conditions for ultrasonic detection of the lesions. Furthermore, ultrasonography of the GI tract is noninvasive, simple, radiation-free, and fairly accurate for the diagnosis of GI obstruction. Therefore, ultrasonography plays a vital role in the evaluation of patients with congenital anomalies of the ...
The female reproductive organs consist of a pair of ovaries, a pair of oviducts and four pairs of spermathecae.The ovaries are a pair of small, whitish, lobed structures, attached to the hinder face of the septum of the 12/13 segment, one on each side of the nerve cord.Each ovary has mature ova towards distal end and immature towards septal side.Each oviducal funnel leads into oviduct which opens outside in the 14th segment in the form of a common oviducal aperture.The four pairs of spermathecae are found on either side of the nerve cord in the 6th, 7th, 8th and 9th segments.Each spermathecae has two parts, a sac like structure, ampulla and a short diverticulum.The diverticulum stores the sperms while ampulla provides a nourishing fluid to them.These spermathecae open outside the bodyby four pairs of apertures one on either ventro-lateral sides of each segmental joint, i.e a pair in the 5-6, 6-7, 7-8, 8-9th segments.The mature ova shed from the ovaries, pass through the oviducal funnels into the ...

The acronym VATER/VACTERL association describes the combination of at least three of the following cardinal features: vertebral defects, anorectal malformations, cardiac defects, tracheoesophageal fistula with or without esophageal atresia, renal malformations, and limb defects. Heiko Reutter et al. performed FGF8 gene analysis in 49 patients with VATER/VACTERL association and 27 patients presenting with a VATER/VACTERL-like phenotype. They identified two heterozygous FGF8 mutations in patients displaying either VATER/VACTERL association (p.Gly29_Arg34dup) or a VATER/VACTERL-like phenotype (p.Pro26Leu) without limb anomalies. These results ...

Cancers of the biliary tract include cholangiocarcinoma (cancers arising from the bile duct epithelium), ampulla of Vater cancer, and gallbladder cancer. All subtypes of biliary tract cancers are rare and have an overall poor prognosis.

While food enters the stomach, those pancreatic juices are secreted inside a system of ducts that culminate in the main pancreatic duct. The pancreatic duct meets the common bile duct to make the ampulla of Vater that is positioned in the first portion of the small intestine, known as the duodenum. The common bile duct originates in the liver and the gallbladder and secretes another important digestive juice known as bile. The pancreatic juices and bile that are secreted within the duodenum, help the body to digest fats, proteins, and carbohydrates.. Endocrine Function:. The endocrine component of the pancreas consists of islets of Langerhans that secrete insulin and glucagon hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, that acts to lower blood sugar level, and glucagon, that acts to raise blood sugar.. Insulin:. ...
Tuberculosis is a major public health problem in developing countries. Though TB commonly occurs in lung, primary abdominal TB is not uncommon, incidence ranging from 0.58% to 12% [1]. But contrary to belief, only 6-38% of patient with active pulmonary TB have abdominal TB [2]. TB does easily disseminate to the gastrointestinal tract, liver, spleen and mesenteric lymph nodes; however the involvement of pancreas is rare. The first report pancreatic TB mimicking cancer was reported by Auerbach in 1944. In his series of 1656 autopsies of tuberculous patients, only 14 cases had direct pancreatic involvement that may have mimicked neoplasia [3]. Since then, most of the medical literature on this rare disease is limited to case reports or small case series. There have been reported incidents in the past where extensive surgeries have been performed for high suspicion of periampullary carcinomas which later turned out to be tuberculosis of the pancreas [4]. Feng Xia et al. have summarized ...
The Whipple procedure is surgery to remove all or part of the pancreas along with part of the stomach, the duodenum, the gallbladder and part of the bile duct. The Whipple procedure is also called pancreaticoduodenectomy.
Spontaneous firing of neurons plays an essential part in the detection of sensory stimuli. Spontaneous firing of primary afferents of ampullary electroreceptor organs in the catfish Ameiurus nebulosus (Lesueur, 1819) was studied in relation to the distribution, thresholds, and frequency characteristics of the electroreceptor organs. The spontaneous firing rate was correlated with the place on the skin. The mean inter-spike interval in 55 dorsal and 49 ventral ampullary organs in five specimens was 16.8 ms +/- 0.41 SEM and 20.5 ms +/- 0.48 SEM, corresponding to firing rates of 59.5 and 48.7 s-1 respectively. The concomitant coefficients of variation were 0.33 and 0.29. Approximately half of the dorsal ampullae were innervated by two fibres. The firing rates of each of the two fibres was lower than the firing rate of organs innervated by a single neuron. Responses to stimuli as weak as 10 pA could be recovered from the noisy average firing level provided the number of averaging sweeps was sufficiently

Anatomy. Bile canaliculi in the liver combine to form the hepatic ducts. The number of hepatic ducts varies from 3-5; they join the extrahepatic biliary system at the cystic duct. The gallbladder lies in the right medial and quadrate liver lobes in the gallbladder fossa. One duct, the cystic duct, leaves the gallbladder and receives the hepatic ducts. After the last hepatic duct has joined the cystic duct, the duct travelling towards the duodenum becomes the bile duct or common bile duct. The common bile duct enters the duodenum on the major duodenal papilla. The bile duct tunnels submucosally aboral to the serosal attachment of the duct; this is more pronounced in dogs than cats. The gallbladder wall contains smooth muscle and the bladder is lined with epithelium, which is rich in mucous-secreting goblet cells.. Diagnostic Imaging. 1. Radiography. Plain film radiography can demonstrate radiodense choleliths. In addition, focal or generalised peritonitis can be suspected when poor abdominal ...

The current Fascicle contains new information accumulated during the last ten years on tumors and tumor-like lesions of the gallbladder, extrahepatic bile ducts and Vaterian system. Because of the increasing number of laparoscopic cholecystectomies and Whipple procedures performed, surgical pathologists now have the opportunity to examine more cancer precursors, early cancers, and adenomas of the gallbladder, extrahepatic bile ducts and ampulla of Vater than previously. These lesions are discussed in detail and profusely illustrated. Likewise, lesions that closely simulate malignant neoplasms are also described and illustrated. Also included are the giant cell neoplasms and the gastrointestinal stromal tumors as well as the new subtypes of carcinomas such as large cell neuroendocrine carcinomas and adenocarcinomas with pyloric gland or foveolar phenotype. The role of immunohistochemistry in the diagnosis of a wide variety of neoplasms is emphasized, as well ...
