[Mirizzi's syndrome].

Two cases of Mirizzi's syndrome are reported. The syndrome consists of: external compression of the common bile duct due to a benign lesion (Type I)--presence of a cholecystobiliary fistula with impacted stones and partial or total obstruction of the hepatic duct (Type II). Clinical signs are non-specific and suggest at first sight an obstructive jaundice. Ultrasonography shows dilatation of the upper biliary tract with narrowing of the biliary tract below the dilatation. ERCP often proves mandatory for diagnosis. Therapeutical procedures are reported.
