An undetectable source of recurrent gastrointestinal bleeding: hemosuccus pancreaticus

Summary: Hemosuccus pancreaticus, a rare cause of upper gastrointestinal bleeding, requires early diagnosis to prevent prolonged suffering and multiple treatments. Visceral artery aneurysm, especially splenic artery aneurysm, is a common source of bleeding. Endoscopy and angiography are commonly used for diagnosis, with angioembolization being the preferred first-line therapeutic approach in most cases.
