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...

Carcinoid tumors of the ampulla of Vater grow slowly and have an excellent prognosis after complete resection of local disease. Histopathological diagnosis is definitive, and the Whipple's procedure is performed as a standard at the present time, although more novel minimally-invasive techniques may be highly useful for selected patients. While tumor size is not a reliable marker of tumor aggression, it is nonetheless related to lymphatic invasion, hence an accurate diagnosis is important if the patient is to be offered the best option available for the treatment of their disease...

The efficacy of lung metastasectomy is well established in several cancers, including colorectal cancer. However, little is known about the result of lung metastasectomy in carcinoma of the ampulla of Vater. Only two case reports have reported the efficacy of metastasectomy in ampullary cancer patients with pulmonary metastasis. We report the result of bilateral lung metastasectomy in a patient with ampullary cancer. A 63-year-old woman underwent pylorus-preserving pancreaticoduodenectomy for carcinoma of the ampulla of Vater...

INTRODUCTION: Large-cell neuroendocrine carcinoma (LCNEC) in the duodenal ampulla of Vater is a rare malignant tumor, with frequent postoperative recurrence and poor prognosis even following complete resection. Effective adjuvant chemotherapy is expected to offer longer survival. PRESENTATION OF CASE: We present two patients with LCNEC accompanied by components of tubular adenocarcinoma/adenoma in the duodenal ampulla of Vater who underwent pancreaticoduodenectomy (PD), resulting in longer survival of 1 patient...

A 57-year-old woman with von Recklinghausen's disease presented with epigastralgia. Gastroduodenoscopy revealed swelling of the ampulla of Vater in the ventral and caudal direction, forming a hard, elastic mass. She was diagnosed with a tumor of the ampulla of Vater, and a subtotal stomach-preserving pancreaticoduodenectomy and D2 lymph node dissection were performed. The isolated specimen showed an intra-ampullary tumor of the ampulla of Vater and a submucosal tumor in the descending duodenum, which were diagnosed as a somatostatin-producing neuroendocrine tumor and gastrointestinal stromal tumor, respectively, on pathological examination...

A 75-year-oldman presenting with obstructive jaundice was referredto our hospital. Basedon a diagnosis of carcinoma of the ampulla of Vater, we performed pancreatoduodenectomy. Postoperative histopathological examination revealed a welldifferentiated papillotubular adenocarcinoma, T3, N0, M0, Stage III . Six months after surgery, an isolatedliver metastasis in S6 was identifiedon CT scan andMRI; therefore, we administeredgemcitabine plus cisplatin chemotherapy. After 6 courses of this regimen, a clinical complete response(CR)was obtained...

INTRODUCTION: Although preoperative therapy is increasingly administered to patients with pancreatic adenocarcinoma, the role of preoperative therapy for patients with adenocarcinoma of the ampulla of Vater is undefined. METHODS: All patients with ampullary cancer who were evaluated between 1999 and 2014 were retrospectively reviewed. Differences in clinicopathologic characteristics, perioperative complications, and overall survival were compared between patients who underwent surgery de novo and those who received preoperative therapy before pancreatoduodenectomy...

BACKGROUND AND AIMS: Biopsy of the ampulla of Vater may be performed to evaluate for ampullary adenomas, suspected ampullary tumors and immunohistological staining for autoimmune pancreatitis. Ampullary biopsies are commonly performed at the time of endoscopic retrograde cholangiopancreatography (ERCP). Due to the well-established complication rate following ERCP, the contribution of ampullary biopsy as a potential independent risk factor would require a controlled comparison. METHODS: A matched-pairs, case-control analysis was performed for patients undergoing ERCP with or without ampullary biopsy...

Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up. Imaging and endoscopy demonstrated a tumor with ulcer in the ampulla of Vater, which was diagnosed as a carcinoma by biopsy. No distant metastasis was observed. Subtotal stomach-preserving pancreaticoduodenectomy was performed...

Carcinoma of the ampulla of Vater associated with annular pancreas is a rare entity. Only seven cases have been reported so far in the English literature. We herein report one such case in a 42-year-lady who presented with progressively increasing jaundice and pain in the upper abdomen for past 2 months. A magnetic resonance cholangiopancreaticography (MRCP) and MRI revealed an annular pancreas with an ampullary mass and a dilated CBD. An upper gastrointestinal endoscopic biopsy from the ampullary mass revealed a moderately differentiated adenocarcinoma...

REVIEW
Chang-Hwan Park
Endoscopic retrograde cholangiopancreatography (ERCP) in post-gastrectomy patients with Billroth II (BII) reconstruction and Roux-en-Y (RY) reconstruction presents a challenge to therapeutic endoscopists. Major difficulties, including intubation to the ampulla of Vater, selective cannulation, and ampullary intervention, must be overcome in these patients. Recent data have shown that device-assisted ERCP allows for high success rates in these patients because various devices are useful for overcoming major difficulties...
