[The Mirizzi syndrome].

Three cases of Mirizzi's syndrome are reported, with special emphasis on differential diagnosis and preoperative evaluation. The syndrome consists of the triad cystic duct stone, inflammatory reaction and benign hepatic duct stenosis. Endoscopic retrograde cholangiography or percutaneous transhepatic cholangiography is mandatory for preoperative evaluation. Cholecystectomy with clearance of the bile duct is the treatment of choice.
