Hemosuccus pancreaticus (HP), a term used for upper gastrointestinal bleeding (UGIB) from the ampulla of Vater through the pancreatic duct, is most commonly caused by the rupture of aneurysm of the splenic artery associated with acute or chronic pancreatitis. It is a rare cause of UGIB, and estimates of its rate (1/1500) are based on small case series. Because of its rarity, the diagnosis is easily overlooked. Here, we have described a case of alcohol-induced acute pancreatitis that developed hemorrhagic shock due to HP.
