[A case of pancreatic pseudocyst with intracystic hemorrhage and repeated gastrointestinal bleeding].

The case is a 83-year-old woman who came to our hospital with melena and epigastralgia as chief complaints, presenting pre-shock state with high serum amylase value. ERP revealed diffuse dilatation of pancreatic duct and cyst of the accessory pancreatic duct. Endoscopy showed hemorrhage of the accessory papilla. A diagnosis of chronic pancreatitis and hemosuccus pancreaticus was made. Because of the patient's advanced age, conservative treatment (total parenchymal nutrition, transfusion, hemostatics, etc.) were prescribed. The patient succumbed due to heart failure 15 months later. This case of gastrointestinal bleeding from a pancreatic pseudocyst due to neighboring arterial rupture is discussed with reference to some related literature.
