Abstract

A duodenal diverticulum is common in the second portion of the duodenum and can occur at any age. An obstruction, bleeding, perforation, diverticulitis are not an uncommon complicationa of duodenal diverticulum. As a rare complication, bleeding in the duodenal diverticulum may be massive, and duodenal diverticulum is resected primarily as a result of the difficulty in determining the site of bleeding. However, there has been a recent increase in endoscopic diagnosis and the treatment of diverticular bleeding. Band ligation increases the risk of duodenal diverticular perforation because of the thin diverticular wall. An endoscopic hemoclip is a preferable method for endoscopic sclerotherapy. We report a 48- year-old man with a giant duodenal diverticulum that was treated with a hemoclip. The duodenal diverticular perforation was treated effectively with supportive care.
