Although colorectal tumors are fairly common surgical conditions, 5 to 12% of these tumors are locally advanced (T4 tumors) upon diagnosis. In this particular situation, the efficacy of en bloc multivisceral resection has been proven. When right-colon cancer invades the proximal duodenum or even the pancreatic head, a challenging dilemma arises due to complexity of the curative surgical procedu...

Introduction. Although ampullary carcinoma has the best prognosis among all periampullary carcinomas, its long-term survival remains low. Prognostic factors are only available for a period of 10 years after pancreaticoduodenectomy. The aim of this retrospective study was to identify factors that influence the long-term patient survival over a 15-year observation period. Methods. From 1992 to 20...

Renal cell carcinoma is the most common primary renal neoplasm in adults. Although renal cell carcinoma is known to spread to unusual sites, the ampulla of Vater is considered a rare site for metastasis. Here we present a case of renal cell carcinoma metastasized to the ampulla of Vater along with literature review. A 62-year-old Korean male had a history of hypertension and right-sided renal c...

OBJECTIVE To evaluate the perioperative outcomes of pancreaticoduodenectomy in a tertiary referral centre in Hong Kong. DESIGN Retrospective case series. SETTING University teaching hospital, Hong Kong. PATIENTS One hundred and forty patients who underwent pancreaticoduodenectomy from July 1989 through June 2001. MAIN OUTCOME MEASURES Mortality and morbidity. RESULTS Overall hospital ...

CONTEXT Familial adenomatous polyposis affects around 2-10 per 100,000 population. Untreated, it inevitably leads to colon cancer. Prophylactic panproctocolectomy has led to improved survival. The resulting extension to follow-up has revealed that 70-100% of patients with familial adenomatous polyposis go on to develop duodenal polyposis and the lifetime risk of duodenal carcinoma in this group...

Pancreaticoduodenectomy remains the exclusive technique for surgical resection of cancers located within both the pancreatic head and periampullary region. Amongst peri-procedural complications, hemorrhage is particularly problematic given that allogenic blood transfusions are known to increase the risk of infection, acute lung injury, cancer recurrence and overall 30-day morbidity and mortalit...

INTRODUCTION About 70% of well-differentiated endocrine tumors arise from the gastrointestinal tract. Duodenal well-differentiated endocrine tumors account for only 2.6% of all neuroendocrine tumors. Following the first two case reports of somatostatin-secreting tumors in 1977, fewer than 200 cases of somatostatinoma have been reported. These tumors of the duodenum are usually silent and asympt...

This study was performed to analyze the efficacy of the prophylactic use of octreotide (Novartis, Stein, Switzerland) for pancreatic fistula following a pancreaticoduodenectomy. The medical records of 190 patients who underwent a pancreaticoduodenectomy at the Samsung Medical Center in Seoul, Korea between January 2000 and December 2002 were reviewed. Patients were divided into either the octre...
