[Intra-hepatic gall bladder complicated by post-operative stones in the common bile duct. The value of endoscopic sphincterotomy (author's transl)].

Two cases of migration of stones in the common bile duct following operation of cholecystitis secondary to cholelithiasis in an intra-hepatic gall bladder are reported. The authors emphasise the difficulties of the operation. When it was necessary to limit surgery to external drainage, migration of stones to the common duct from the gall bladder left in place is possible. In the two cases presented, endoscopic sphincterotomy resulted in the early expulsion of the calculi and permanent drainage of the common bile duct, a presumptive guarantee against the complications of new migrations.
