After the patient was diagnosed with liver hemangioma showing extrahepatic growth,we performed a handassisted laparoscopic partial hepatectomy.The resected specimen was 11×10×8 cm in diameter and 424g in weight. A histopathological analysis revealed that the tumor was a cavernous hemangioma. Hand-assisted laparoscopic surgery permits an adequate surgical field, and other essential management procedures during surgery.Laparoscopic hepatectomy using hand-assisted laparoscopic surgery is thus one of several effective procedures that provide a superior level of operability and safety, Article, 信州医学雑誌, 58(6):313-318 (2010)}, pages = {313--318}, title = {腹腔鏡補助下に切除した肝外発育型巨大肝血管腫の1例}, volume = {58}, year = {2010} }
