Background/Purpose: The purpose of this study was to evaluate the efficacy of laparoscopy-assisted liver surgery, to introduce laparoscopic surgery for hepatectomy.Operative procedure: After the mobilization of the liver under the laparoscope, hepatectomy was performed through the small skin incision as the same procedure as the conventional hepatectomy without the laparoscope.Method: Between 2009 and Jun. 2011, 31 patients underwent laparoscopy-assisted hepatectomy (Laparoscopic group). Twenty-seven patients who underwent conventional hepatectomy under wide incision without laparoscope were control as a matched group (Open group). Operation time, operative blood loss, total amount of transfusion and the short term outcome were compared.Result: Operating time in the laparoscopy group was significantly longer than that of the open group. There were no significant differences in other operating factor and postoperative complications. Short term outcomes was not significantly different because of the same clinical pathways in both groups.Conclusion: Laparoscopy-assisted hepatectomy is feasible and well tolerated. It seemed to be minimal invasive and useful as the early stage of the introduction of laparoscopic surgery for hepatectomy.
