The strategy for Mirizzi syndrome type II with laparoscopic surgery: A case report

INTRODUCTION: Mirizzi syndrome is an unusual condition involving gallstones. Laparotomy is recommended for the treatment of Mirizzi syndrome type II due to the risk of biliary duct injury. We herein report tips for performing laparoscopic surgery for Mirizzi syndrome type II as a treatment option. PRESENTATION OF CASE: A 72-year-old woman was admitted to our hospital due to abdominal pain and a fever. The diagnosis of Mirrizi syndrome type II was made. Therefore, an endoscopic retrograde biliary drainage tube was placed, and laparoscopic surgery was performed. During the operation, the gallbladder wall was excised at the Hartmann's pouch, and a gallstone was extracted. A fistula between the gallbladder and bile duct was confirmed, and the diagnosis of Mirizzi syndrome type II was made. Partial resection of the gallbladder was performed, and the neck of the gallbladder was sutured. The postoperative course was uneventful. DISCUSSION: The preoperative diagnosis is important for Mirizzi syndrome, and the combination of various modalities, including endoscopic retrograde cholangiopancreatography, can increase the diagnostic rate. It is often difficult to recognize the anatomy during surgery for Mirizzi syndrome due to severe inflammation. Therefore, it is best to dissect the gallbladder from the bottom, perform excision at the Hartmann’s pouch, remove the gallstone and suture the gallbladder wall. Replacement of the biliary tube can aid in recognizing the anatomy and bile duct. CONCLUSION: Laparoscopic surgery for Mirizzi syndrome is a viable treatment option following an accurate preoperative diagnosis and the recognition of the anatomy during the operation.
