â  the ampulla of vater is commonly located in the posteromeâ­dial wall of the second portion of the duodenum. at times, the ampulla of vater may be found at uncommon sites such as the third and fourth portions of the duodenum, the duodenal bulb and the stomach. we found the ampulla of vater in the pyloric channel in a 44 year old patient who had undergone surgery for acute cholecystitis. an in...

A 51-year-old male presented with abdominal pain and jaundice. He was subsequently diagnosed with cholestatic jaundice and cholangitis. A side-viewing duodenoscope failed to identify the ampulla of Vater in the second portion of duodenum. A regular gastroscope was used, and an ectopic ampulla of Vater was identified in the pyloric channel.

Ectopic pancreas is an uncommon condition and is usually found in the gastrointestinal tract, such as stomach, duodenum and jejunum. However, ectopic pancreas in the ampulla of Vater is rare and its clinical presentations may be similar to periampullary cancer. It is difficult to diagnose preoperatively. We present such a case where the diagnosis was proven postoperatively. Our patient, a 51-ye...

BACKGROUND Type 1 neurofibromatosis (NF-1) is an autosomal dominant disorder with variable penetrance; approximately 50% of cases present as new mutations CASE REPORT We report a case of a 56 year-old man with Von Recklinghausen's disease, carcinoma of the ampulla of Vater and incidental benign gastrointestinal stromal tumours of the jejunum. CONCLUSIONS Coexistence between ampullary carcin...

Herein, we present a case of coexisting neuroendocrine carcinoma and conventional adenocarcinoma (collision tumor) in the ampulla of Vater, which has seldom been reported in the literature. A 51-year-old man presented with a month history of jaundice. MRCP disclosed about 1.9×1.8 cm sized heterogeneously enhancing mass in ampulla of Vater, causing obstructions of distal common bile duct. He und...

BACKGROUND Neuroendocrine tumors (NETs) of the ampulla of Vater are rare and difficult to diagnose. We report a rare case of a small NET of the ampulla of Vater with metastasis to distant lymph nodes. CASE PRESENTATION The patient was a 54-year-old man complaining of epigastric pain and melena. Upper gastrointestinal endoscopy revealed a bulging papilla with active bleeding, which was diagnos...

There has been no report for the expression of cyclooxygenase-2 (COX-2) and its clinicopathologic and biologic significance in ampulla of Vater cancer. This study was aimed for the clarification of COX-2 expression and its biologic roles in ampulla of Vater cancer. Fourty-six patients with ampulla of Vater cancer were enrolled and their COX-2 expression and clinicopathologic features were analy...

CONTEXT Acute recurrent pancreatitis still poses diagnostic difficulties. The coexistence or moreover the causative relationship of carcinoma of the ampulla of Vater and acute recurrent pancreatitis is fairly rare. CASE REPORT We present a case of carcinoma of the ampulla of Vater that presented with acute recurrent necrotizing pancreatitis complicated with pseudocysts. A diagnosis of maligna...

PURPOSE Tumors arising from the ampulla of Vater can be benign or malignant. Recently, endoscopic papillectomy has been employed in the management of benign ampulla of Vater tumors; however, surgical resection is the treatment of choice. The aim of this study was to define indications and suggest a role for transduodenal ampullectomy in the management of ampulla of Vater tumors. METHODS We re...
