MIRIZZI SYNDROME: A CLASSIFICATION BASED ON TREATMENT

Abstract

Thirty-two patients with the Mirizzi syndrome, encountered between 1980 and 1997 were classified into three groups. Type 1 consisted of patients with common bile duct obstruction due to external compression by a gallstone impacted at the infundibulum of the gallbladder (18.7%); Type II included cholecystobiliary fistulization however, the stone remained in the gallbladder (25%). Type III patients had complete integration between the gallbladder and the common bile duct and the calculi occluded the common bile duct (56.3%). Surgery was performed in 93% of the patients with a mortality rate of 6.2%.
