Mirizzi syndrome (MS) is a rare complication for patients who underwent laparoscopic cholecystectomy for gallstone diseases. Most cases are treated by surgical intervention. However, because of its technical difficulty with laparoscopic surgery, Mirizzi syndrome underlying cystic duct anomalies is considered clinically important. We report a case of a 54-year-old male patient who presented with right upper quadrant pain, tenderness and a history of previous laparoscopic cholecystectomy. The patient also showed a CT evidence of cholangitis due to remnant cystic duct calculi. We performed an Endoscopic retrograde cholangiopancreatography (ERCP) which revealed Mirizzi syndrome with an uncommon anomalous cystic duct, namely, a low lying cystic duct. This case shows that endoscopic retrograde cholangiopancreatography with biliary stenting combined ursodeoxycholoic acid treatment can be utilized in suitable cases of MS caused by remnant cystic duct calculi after cholecystectomy.
