title: Hemosuccus pancreaticus (hemoductal pancreatitis): gastrointestinal hemorrhage due to rupture of a splenic artery aneurysm into the pancreatic duct.
abstract: A patient with recurrent upper gastrointestinal bleeding was found to have pancreatitis and a pseudoaneurysm of the splenic artery that communicated with the pancreatic duct. Similar pathology noted in ten other patients found in an extensive review of the literature suggest that this rare entity must be considered in the diagnosis of gastrointestinal hemorrhage of obscure origin. In this collected experience, the combination of recurrent left upper quadrant pain, a history of pancreatitis, and recurrent bouts of gastrointestinal bleeding of obscure origin were usually present in those patients who were found to have a splenic artery aneurysm as the source of the blood loss. Distal pancreatectomy with resection of the splenic artery aneurysm is curative.
