The endoscopic variety of duodenal villous adenoma - an experience with ten cases.

Ten cases of villous adenoma of the duodenum among 8,754 endoscopic examinations of the upper gastrointestinal tract were found over a nine year period. The varied clinical manifestations included gastrointestinal bleeding in five cases, partial duodenal obstruction in four, and jaundice with common bile duct obstruction in two. In only two cases did radiological examination indicate the diagnosis of villous adenoma of the duodenum in all ten cases preoperatively but was negative for carcinoma in one. Due to improved diagnostic techniques villous adenoma of the duodenum is being diagnosed at an early stage, and with appropriate surgical treatment the survival rate for this group of patients should improve.
