ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY - MIRIZZI SYNDROME

Mirizzi's syndrome is characterized by compression and or stenosis of the common duct as a consequence of impaction of a stone in the gallbladder neck, the cystic duct and eventually by a cholecystobiliary fistula. Preoperative diagnosis is important to avoid iatrogenic injury of the biliary tree. We present two cases with Mirizzi's syndrome confirmed at operation in whom ERCP was done prior to the operation. In one of them the examination was diagnostic, while in the other, cystic duct compression and absence of the gallbladder image were the non-specific findings.
