Mirizzi syndrome complicated by type IV cholecystobiliary fistula to the right hepatic duct

ABSTRACT

Mirizzi syndrome is a rare complication of long-term chronic cholecystitis, characterized by extrinsic compression of the common hepatic duct that may progress to development of cholecystobiliary fistula.Here we report a case of a 38-year-old female patient who underwent laparoscopic cholecystectomy with intraoperative cholangiogram for acute cholecystitis and choledocholithiasis. Intraoperatively, the patient was found to have a Mirizzi syndrome complicated by cholecystobiliary fistula to the right hepatic duct. The gallbladder was successfully removed, cholelithiasis cleared and a ureteral stent was used in reconstruction. The patient was discharged on postoperative two and was doing well on routine follow-up. Ultimately, Mirizzi syndrome is a rare clinical entity that requires careful consideration during preoperative workup and a high suspicion when abnormal anatomy is encountered intraoperatively.
