Adenocarcinoma of the third and fourth portions of the duodenum: results of surgical treatment.

Hypothesis: To verify the adequacy of duodenal segmentectomy after intestinal derotation in the treatment of primary adenocarcinoma of the third and fourth portions of the duodenum.

Design: A retrospective review of the surgical management of patients who underwent derotation of the third and fourth portions of the duodenum was undertaken to determine long-term outcome.

Setting: Departments of surgery in 3 university hospitals.

Late development of bile duct cancer in patients who had biliary-enteric drainage for benign disease: a follow-up study of more than 1,000 patients.

Objective: To evaluate the correlation between biliary-enteric surgical drainage and the late development of cholangiocarcinoma of the biliary tract.

Summary Background Data: In patients with biliary-enteric drainage, reflux of intestinal contents into the bile duct may occur and cause cholangitis, which is regarded as the most serious complication of these procedures. Lithiasis of the biliary tract and a previous biliary-enteric anastomosis have both been suggested to favor the late onset of cholangiocarcinoma.
