Massive gastric bleeding-perforation of pancreatic pseudocyst into the stomach: A case report and review of literature

摘要

BACKGROUND Pancreatic pseudocyst may cause serious gastrointestinal complications including necrosis,infection,and perforation of the gastrointestinal tract wall,but massive gastric bleeding is very rare.CASE We report a rare case of a 49-year-old man with life-threatening gastric bleeding from a pseudoaneurysm of the splenic artery perforating the stomach induced by pancreatic pseudocyst.During hospitalization,gastroscopy revealed a bare blood vessel in an ulcer-like depression of the greater gastric curvature,and computed tomography scan confirmed a pancreatic pseudocyst invading part of the spleen and gastric wall of the greater curvature.Arteriography showed that the bare blood vessel originated from a pseudoaneurysm of the splenic artery.The bleeding was controlled by the trans-arterial embolization,the patient’s recovery was rapid and uneventful.CONCLUSION Massive gastrointestinal bleeding could be a rare complication of pancreatic pseudo aneurysm.
