Mirizzi syndrome type III represents a more advanced stage in which a cholecystobiliary fistula has developed, eroding between one-third and two-thirds of the circumference of the common bile duct. This anatomical extent distinguishes it from lower-stage disease and directly shapes the surgical strategy required.
In type III Mirizzi syndrome, the fistula involves between one-third and two-thirds of the common bile duct's circumference — accounting for a substantial proportion of cases. The degree of ductal involvement determines the reconstructive approach needed beyond simple cholecystectomy.
Management involves cholecystectomy combined with removal of the affected bile duct and biliary reconstruction. The full sequence of steps, technical considerations, and decision points are detailed in the complete protocol.
