[Hemobilia, a rare and dangerous postoperative complication].

3 cases of severe postoperative hemobilia are reported, one patient with an echinococcus cysticus of the liver, two others after surgical procedures on biliary tract. Diagnostic means as cholangiography, coeliacography, scanning of the liver and endoscopic retrograde cholangiography were not possible because of the massive bleeding. In those cases, if no other sources of bleeding are found, only esophago-gastro-duodenoscopy can leed to the correct diagnosis. In gastrointestinal bleeding after surgical manipulation on the biliary tract, the duodenum and the pancreas, hemobilia is a possible cause.
