Endoscopic management of upper gastrointestinal bleeding from a duodenal diverticulum

Hemorrhage from duodenal diverticulum is a rare cause of upper gastrointestinal hemorrhage. The side-viewing endoscope was used for almost all cases of diagnosis and endoscopic hemostasis. However, a forward-viewing endoscope is used in emergent endoscopic study for upper gastrointestinal hemorrhage. We report a case in which the endoscopic hemostasis of bleeding duodenal diverticulum was performed during emergent forward-viewing endoscopic study.
