Life-Threatening Upper Gastrointestinal Hemorrhage in Hemosuccus Pancreaticus: A Case Report.

Hemosuccus pancreaticus (HP) is a rare cause of upper gastrointestinal bleeding caused by bleeding from the ampulla of Vater into the duodenum. HP most commonly results from a rupture of pseudoaneurysms secondary to chronic pancreatitis. The low incidence of HP and the wide spectrum of its clinical presentation poses diagnostic challenges. We present a case of a 39-year-old male with acute-on-chronic pancreatitis resulting in HP and obstructive jaundice due to pancreatic pseudocyst with secondary hematoma. This case highlights the rare occurrence of hypovolemic shock due to massive hemorrhage in HP and the successful management with prompt cardiovascular support and angiographic coil embolization of a bleeding pancreatic pseudoaneurysm.
