[Biliary peritonitis caused by perforation of the intra-hepatic biliary ducts. 2 new cases].

Two cases of biliary peritonitis by perforation of intra-hepatic biliary ducts are presented. In both cases there is a perforation from a gallstone. In the first case the perforation is located at the proximal part of the left hepatic bile duct, in the second case it is at the proximal and distal portion of the third segment bile duct. Those peritonitis are rare and their diagnosis is difficult. Gallstone is the main cause. Removing bile duct obstruction is the treatment.
