 Laparoscopic deroofing for symptomatic giant liver cysts requires sufficient fenestrations and wall resection to avoid cystic encapsulation. However, extended deroofing may result in damage of the bile ducts running in the cyst wall. We report a case of laparoscopic deroofing which was performed successfully using intraoperative indocyanine green fluorescent cholangiography. An 83 years old male patient was admitted to our hospital due to right abdominal distension. Abdominal computed tomography detected two huge hepatic cysts in the right hepatic lobe. Laparoscopic deroofing was performed. Bile ducts crossing on the cut line of the cyst wall were clearly detected by indocyanine green fluorescent cholangiography, and those bile ducts were securely clipped. Indocyanine green fluorescent cholangiography is a simple and useful technique to avoid biliary injury during laparoscopic deroofing of the liver cysts.
