Laparoscopic liver resection remains limited to a relatively small number of institutions because of insufficient hepatic and laparoscopic surgical experience and few training opportunities. The aim of this study was to assess the feasibility and safety of an improved laparoscopic left lateral sectionectomy technique as a training procedure for new surgeons.


Twenty-four laparoscopic left lateral sectionectomies (LLLSs) were retrospectively reviewed. Patients were divided into 3 groups with 8 patients in each: those undergoing surgery by expert surgeons prior to 2008 (Group A); those undergoing surgery by expert surgeons after 2008, when a standardized LLLS technique was adopted (Group B); and those undergoing LLLS by junior surgeons being trained (Group C).


The median operative time was significantly shorter for Group B (103 min; range, 99–109 min) and C (107 min; range, 85–135 min) patients than for Group A (153 min; range, 95–210 min) patients. There were no significant differences in blood loss or hospital stay. In Groups B and C, no conversions to open laparotomy or complications occurred.


The standardized LLLS procedure was both safe and feasible as a technique for training surgeons in laparoscopic hepatectomy.
