ampullary tumor is a rare cancer. these patients most commonly present with obstructive jaundice but sometimes disease appear with uncommon signs. this report is an example of such cases. our case is a 53 year old man who presented with recurrent fever and chills and iron deficiency anemia and has been misdiagnosed for two years. the proper diagnosis occurred when the patient showed abnormal li...

A 66 year old female was found to have an ampullary mass on endoscopic examination. A pancreaticoduodenectomy was performed and the pathology was consistent with carcinoid tumor. Carcinoid tumors of the ampulla of Vater are rare tumors of the gastrointestinal tract, accounting for 0.3-1% of gastrointestinal carcinoids. Management of ampullary carcinoid tumor with pancreaticoduodenectomy is in a...

Ampullary adenoma is a common indication for endoscopic papillectomy. Ampullary neuroendocrine tumor (NET) is a rare disease for which complete surgical resection is the treatment of choice. However, because of the morbidity and mortality associated with surgical resection, endoscopic papillectomy is increasingly used in selected cases of low grade, with no metastasis and no invasion of the pan...

The ampullary region is a highly complex anatomic area composed of the following histologically and functionally distinct structures: the ampullary common duct or ampulla, formed by the dilated confluence of the pancreatic and common bile duct; the sphincter of Oddi; and the duodenum with the papilla of Vater, where the ampulla opens into the duodenum [1]. Due to its complexity, this small anat...

BACKGROUND We investigated the occurrence and clinical significance of mucin expression in ampullary adenocarcinoma. METHODS We retrospectively analyzed clinical, pathological, and survival data from 74 ampullary adenocarcinoma patients who received radical operation from January 2004 to November 2006. RESULTS The tumors were located in the lower end of the common bile duct (46%), papillary...

BACKGROUND Considerable controversy surrounds the treatment of ampullary neoplasms. This report describes the authors' experiences regarding the choice of either ampullectomy or pancreaticoduodenectomy for treatment of ampullary tumors. METHODS Demographics, statistical findings concerning diagnosis, surgical risks including morbidity and mortality, and outcomes were evaluated and compared be...

Background: Pancreaticoduodenectomy or Whipples’s procedure is done for pancreatic carcinoma, bile duct carcinoma, duodenal carcinoma and periampullary carcinoma. About 5% of the gastrointestinal malignancy is constituted by the ampullary and periampullary carcinoma. Histopathological studies related to the diagnosis, grade, stage, nodal status, marginal status, prognosis and incidence of these...

Introduction: Pedunculated ampullary adenoma is a rare periampullary tumor. There is still controversy regarding whether to perform local ampullectomy or radical resection for adenomas with severe dysplasia. Case Description: A 57-year-old man was diagnosed with a large, long pedunculated ampullary tumor arising from the second portion of the duodenum. Histologic examination of the biopsy speci...

INTRODUCTION Whipple's Pancreaticoduodenectomy has increasingly been used as an appropriate resectional procedure for tumors of the periampullary region which are pancreatic, periampullary, ampullary and biliary tumors. Our aim was to study the distribution and histopathologic features of these tumors and to examine local trends of periampullary neoplasms resected with a PD. METHODS A descrip...
