[Hemosuccus pancreaticus--a rare cause of upper gastrointestinal bleeding. Successful treatment in two cases by radiologic-interventional embolization of the splenic artery].

HISTORY AND CLINICAL FINDINGS: Two patients were admitted to hospital for diagnosis of recurrent upper gastrointestinal bleeding. Both had chronic pancreatitis with alcohol abuse. Their general condition was satisfactory. Physical examination showed no diagnostic abnormalities other than mild epigastric pain on pressure in one patient.

INVESTIGATIONS: In case 1 angiography revealed pseudoaneurysm of the splenic artery as a complication of chronic pancreatitis to be the cause of the bleeding. In case 2 sonography demonstrated multiple pancreatic pseudocysts after recurrent pancreatitis. Duplex sonography revealed one of the cyst to be a partly thrombosed pseudoaneurysm of the splenic artery and the source of the bleeding.

TREATMENT AND COURSE: In both cases a fistula between splenic artery and pancreatic duct having been shown to be the source of the bleeding, transcatheter embolisation of the splenic artery with platinum coils was successfully undertaken. Both patients remained symptom-free 4 and 10 months later.

CONCLUSION: Although haemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding, given certain features in the patient's history and the clinical findings, it should be included in the differential diagnosis.
