In a laparoscopic hepatectomy, it is important to control bleeding from liver parenchyma. Microwave pre-coagulation is an effective technique to achieve good hemostasis during hepatic resection. On the other hand, there is a suspicious risk of causing bile leakage and bile duct strangulation due to the biliary damage after microwave coagulation. We report a case of hepatic biloma after laparoscopic partial hepatic resection for hepatocellular carcinoma using microwave pre-coagulation.
