[Mirizzi syndrome with cholecystoduodenal fistula--a rare complication of cholecyctolithiasis].

Mirizzi syndrome is a rare complication of the long-term gallbladder stone disease. It's caused by a gallbladder stone impression to the common bile duct wall. The clinical appearance is an obstructive jaundice, pain in right subchondrium and dyspepsia. Higher pressure in the extrahepatal bile ducts leads to biliobiliary or enterobiliary fistula formation. In the described case a cholecystoduodenal fistula was found. Preoperative diagnosis of MS is a medical challenge, and majority of the diagnosis is set introperatively. Surgery is the treatment of first choice. Ignoring the possibility of MS can seriously damage patient's health by injuring bile ducts during the surgery.
