The Mirizzi syndrome (MS), a rare condition, is a late complication of chronic cholecystitis. It is a spectrum of disease ranges from simple compression of common hepatic duct to cholecystobiliary fistula (CBF). The clinical presentation is similar to symptomatic cholelithiasis like abdominal pain, vomiting, jaundice etc, hence it is difficult to diagnose preoperatively. Even peroperatively it is diagnosed by expert surgeon who has experience in hepatobiliary surgery, otherwise chances of biliary duct injuries are high.
