Hemosuccus pancreaticus: a cause for obscure gastrointestinal bleeding--diagnosis by endoscopy and successful management by total parenteral nutrition.

Hemorrhage through the pancreatic duct (hemosuccus pancreaticus) is discussed in a patient with alcoholic chronic pancreatitis and anemia. The pancreatic duct as the source of bleeding was determined by use of duodenoscopy; abdominal arteriograms were normal. It is postulated that the patient's bleed was intermittent and of venous origin, probably associated with pancreatic pseudocyst formation. Total parenteral nutrition could be considered in treatment of the condition if bleeding is not life threatening.
