[Diagnostic and therapeutic strategy in extrahepatic biliary lithiasis. Our experience].

The paper describes the Authors' personal experience in the diagnosis and treatment of extrahepatic biliary lithiasis in 166 patients admitted to the Surgical Division of the International Evangelical Hospital. The basic tests for a correct diagnostic strategy are echotomography and ERCP in cases of jaundice and/or dilatation of the biliary tract with negative echographic results for lithiasis of the choledochus. The indications for surgery are also discussed and the new possibilities of pre- and post-operative PSTE are also taken into account.
