肝focal nodular hyperplasiaに対する腹腔鏡下肝切除術

Recently, laparoscopic hepatectomy of the liver has been reported to be safe, with possible advantages to the patients such as reduced postoperative pain and shorter hospital stay. We report successful laparoscopic partial liver resections for two cases of focal nodular hyperplasia.
Two cases of 43-year-old male and 69-year-old male, with chronic hepatitis C and without any symptoms, presented in each other a solitary mass 1.5 and 1.0 cm in size at the edge of the liver on diagnostic imagings. The patients underwent laparoscopic partial hepatectomy to rule out well differentiated hepatocellular carcinoma. The histopathological diagnosis was focal nodular hyperplasia. Each patient had an uneventful postoperative recovery and had been free from recurrence during the 6 years follow-up period. Laparoscopic partial hepatectomy is indicated in patients with benign solid mass located at the edge of the liver.
