Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and abstruse neoplasms with increasing incidence and clinical relevance. The National Cancer Data Base was examined to identify GEP-NET cases from 2004 to 2013. In total, 39,454 patients diagnosed with GEP-NET were identified. Median age was 61 years. Majority was female (50.13%), white (79.49%), and had low-grade neoplasms (84.39%). On univariate analysis, age, sex, race, primary site, tumor size, and regional lymph node involvement were associated with tumor grade (P < 0...

Gangliocytic paraganglioma is an uncommon tumor, which is usually located in the ampulla of Vater, and may get confused in the differential diagnosis with ampuloma or GIST. Here we present a case of a patient with upper gastrointestinal bleeding as a predominant symptom, objectified by endoscopy an ulcerative polypoid mass at the juxtapilar level, with histological result of gangliocítica paraganglioma after multiple biopsies, and finally surgical resection. The interest of this case is the difficulty for diagnosing, the different treatments and prognosis that this implies, especially for the tumor location, as surgery can lead to great complications...

Biliary tract cancer (BTC) is one of the most devastating types of malignant neoplasms worldwide. However, the mechanisms underlying the development and progression of BTC remain unresolved. BTC includes extrahepatic bile duct carcinoma (EBDC), gallbladder carcinoma (GBC) and ampulla of Vater carcinoma (AVC), named according to the location of the tumor. Although genetic alterations of intrahepatic cholangiocarcinoma have been investigated, those of EBDC, GBC and AVC have not yet been fully understood. The present study analyzed somatic mutations of 50 cancer-associated genes in 27 Japanese BTC cells, including: 11 EBDC, 14 GBC and 2 AVC...

INTRODUCTION: The ampulla of Vater consists of papilla, common channel, distal common bile duct and the distal main pancreatic duct. Ampullary carcinomas arise from two different types of mucosa, reflecting their broad histomorphological spectrum. Adenocarcinomas originating in the ampulla of Vater are classified as having either 'Intestinal' or 'Pancreatobiliary' type of differentiation. Pancreatobiliary type has consistently shown a worse prognosis. Various types of mucins are distributed in normal tissues and gastrointestinal tumours...

Pancreaticobiliary maljunction (PBM) is a congenital malformation that is associated with biliary cancer development. When patients are diagnosed with PBM, a diversion operation is recommended. Although a risk remains for developing residual bile duct carcinoma following diversion, the development of a carcinoma of the ampulla of Vater after a diversion operation for PBM is rare. We present a treated case of carcinoma of the ampulla of Vater after a diversion operation for PBM. A 65-year-old woman presented with abdominal pain...

Afferent loop syndrome (ALS) is a rare complication of Billroth-II gastrojejunostomy. Causes of afferent loop obstruction include adhesions, internal hernias, intestinal strictures or malignancy. Obstruction caused by enteroliths is rare and usually requires surgery. We present the case of a 90-year-old man with a Billroth-II performed 50 years earlier and three acute pancreatitis. He presented with acute abdominal pain, without signs of pancreatitis. Upper digestive endoscopy revealed a punctiform anastomotic stricture of the afferent loop...

Portal hypertensive biliopathy (PHB) is described as abnormalities of the walls of the biliary tree secondary to portal hypertension. Gastrointestinal bleeding caused by PHB is rare. PHB as a cause of serious bleeding after sphincteroplasty during ERCP is extremely rare. Here, we report a case of PHB in a young Saudi male with cell sickle anemia who developed massive hemorrhage during ERCP after balloon dilation of the ampulla of Vater. We further discussed the diagnosis and management. To the best of our knowledge, no such case has been reported...

BACKGROUND: Delayed gastric emptying (DGE), a common postoperative complication of pancreaticoduodenectomy, is not considered a life-threatening complication. In the present study, we analyzed the risk factors for DGE and its impact on long-term prognosis. METHODS: We analyzed 383 patients who underwent pancreaticoduodenectomy between 2003 and 2010, dividing them into two groups according to DGE grade as defined by the International Study Group of Pancreatic Surgery: 243 without DGE (non-DGE group) and 140 with DGE of any grade (DGE group)...

REVIEW

Cholangiocarcinoma is an epithelial malignancy arising in the region between the intrahepatic bile ducts and the ampulla of Vater at the distal end of the common bile duct. The effect of current chemotherapy regimens against cholangiocarcinoma is limited, and the prognosis of patients with cholangiocarcinoma is poor. Aberrant DNA methylation and histone modification induce silencing of tumor suppressor genes and chromosomal instability during carcinogenesis. Studies have shown that the tumor suppressor genes and microRNAs (miRNAs) including MLH1, p14, p16, death-associated protein kinase (DAPK), miR-370 and miR-376c are frequently methylated in cholangiocarcinoma...

AIMS: PD-1/PD-L1 checkpoint immunotherapy has recently been proposed as a promising treatment in relapsed/refractory disease, eventually used in combination with the traditional chemotherapy in different cancer settings. No data are still now available about PD-L1 expression in ampulla of Vater carcinoma and its preinvasive lesions. METHODS AND RESULTS: We assessed the immunohistochemical expression of PD-L1 in a series of 26 ampullary adenocarcinomas, 50 ampullary dysplastic lesions, and 10 normal duodenal mucosa samples...

BACKGROUND: This series of patients with a history of Roux-en-Y gastric bypass (RYGB) and cholecystectomy presented with symptoms consistent with obstructive biliary disease and massive biliary dilation of ≥15 mm, suggesting a structural cause. Findings from laparoscopic-assisted transgastric (TG) ERCP were a normal-appearing ampulla without structural lesions or stones, suggesting a functional cause instead. STUDY DESIGN: Patients who underwent TGERCP from January 2008 to October 2016 and had a surgical history of RYGB and cholecystectomy were identified from an institutional database...

Trends in biliary tract cancer incidence rates have increased in Shanghai, China. These trends have coincided with economic and developmental growth, as well as a shift in dietary patterns to a more Westernized diet. To examine the effect of dietary changes on incident disease, we evaluated associations between diet and biliary tract cancers amongst men and women from a population-based case-control study in Shanghai, China. Biliary tract cancer cases were recruited from 42 collaborating hospitals in urban Shanghai, and population-based controls were randomly selected from the Shanghai Household Registry...

Background and Objectives: The standard treatment for carcinomas of the ampulla of Vater (CAV) is surgical resection. Nevertheless, recurrence is observed in half of the patients within five years after cancer surgery. In this study, we aimed to identify predictive factors and develop a nomogram capable of predicting the risk of recurrence in post-resection CAV patients. Methods: Our study cohort was composed of two hundred and twelve patients who had undergone radical surgery for CAV between 2000 and 2012...

We report the case of a 57-year-old man with a 1.0-cm grade 1 neuroendocrine tumor (G1 NET) of the ampulla of Vater (ampullary NET) who underwent endoscopic snare papillectomy. Pancreatitis occurred after endoscopic resection but was cured with conservative therapy. In two years of follow-up, no local recurrence or metastasis occurred. Endoscopic snare papillectomy for small G1 NET of the ampulla of Vater is relatively safe and less invasive than surgical treatment and should be considered as treatment option...

Background: Although carcinoma of the ampulla of Vater (CAV) is a rare tumor, accounting for just 0.2% of gastrointestinal cancers, the survival of CAV patients is unfavorable. The five-year rates have ranged from 36.8-75.2% in previous reports but there is a lack of data relating to Thai people. Also prognostic factors are controversial. Objectives: This study aimed to determine survival outcomes and to identify prognostic factors for a positive outcome for CAV patients after surgery. Methods: In this retrospective cohort study, data were collected from CAV patients who underwent surgery in Chiang Mai University Hospital from 2005 to 2012 for time to event analysis, the log rank test and univariate and multivariate Cox’s regression analysis...

INTRODUCTION: Duodenal gangliocytic paragangliomas are rare neoplasms often arising in proximity to the major duodenal papilla of Vater. These neoplasms are considered to have a benign behavior with lymph node metastases being a rare phenomenon and distant metastatic disease even more so. Resection of the tumor is the only definitive therapy. PRESENTATION OF CASE: A 67year old male presented to a referring hospital with symptoms of fatigue and malaise. Evaluation with CT imaging revealed a 3...
