Hemosuccus Pancreaticus (HP) is a rare & potentially life threatening clinical entity. It is described as bleeding from Ampulla of Vater via the Pancreatic Duct (PD).This condition is classically attributed to erosion of Splenic artery Aneurysm into the PD or bleeding into a pseudocyst as a result of Acute or Chronic Pancreatitis causing intermittent severe upper gastrointestinal (GI) bleeding. It poses a significant diagnostic & therapeutic dilemma because of its rarity, anatomic location & intermittency of bleeding. When Obscure GI bleeding is encountered, HP should be considered in cases of pancreatitis. Mesenteric Angiographic intervention remains the modality of choice for diagnosis & treatment. However if embolization of bleeding vessel fails, emergency surgery should be undertaken. We describe our experience with a case of HP who presented to us with hematochezia with hemodynamic instability and the diagnostic as well as therapeutic difficulties faced.
