Hemosuccus pancreaticus , also known as pseudohematobilia or Wirsungorrhage , is a rare cause of hemorrhage in the gastrointestinal tract . It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery , that bleed into the pancreatic duct. Patients with hemosuccus may develop symptoms of gastrointestinal hemorrhage, such as blood in the stools, maroon stools, or melena . They may also develop abdominal pain. Hemosuccus pancreaticus is associated with pancreatitis , pancreatic cancer and aneurysms of the splenic artery . Angiography may be used to diagnose hemosuccus pancreaticus, where the celiac axis is injected to determine the blood vessel that is bleeding. Concomitant embolization of the end vessel may terminate the hemorrhage. Alternatively, a distal pancreatectomy may be required to stop the hemorrhage.
