Hemosuccus pancreaticus is a rare clinical condition, defined as a bleeding from an artery around the pancreas or a lesion on the pancreas, to the pancreatic duct. The intensity of bleeding can vary from occult bleeding to life threatening massive acute bleeding. In this article, we aimed to present a 68-year-old man who presented to our clinic with recurrent upper gastrointestinal bleeding and abdominal pain. Endoscopy revealed hemorrhage from ampulla vateri, CT angiographic examination showed an aneurysm of the splenic artery and that the splenic artery was connected to the pancreatic duct.Splenectomy and subtotal pancreatectomy was performed on the patient. The patient was discharged with healing. Hemosuccus pancreaticus should be kept in mind in patients with a history of pancreatitis and peripancreatic aneurysm and upper gastrointestinal bleeding. The early diagnosis and treatment of HP is life-saving. In this study, we aimed to review the basic symptoms and clinical findings, along with the diagnosis and treatment methods of HP.
