[Surgical Outcomes of Laparoscopic Repeat Hepatectomy at Our Institution]

Laparoscopic hepatectomy has gained popularity owing to its merits, such as low invasiveness and reduced bleeding. However, the efficacy of laparoscopic repeat hepatectomy(LRH)has not been confirmed. The aim of this study was to evaluate the feasibility and efficacy of LRH compared to that of open repeat hepatectomy(ORH). We performed 60 repeat hepatectomies from January 2011 to March 2019, of which 19 were LRH(Lap group)and 41 were ORH(Open group). This study retrospectively compared the patient characteristics and short-term outcomes of repeat hepatectomy between the Lap and Open groups. There were no significant differences in patient characteristics, except for the type of approach in the previous hepatectomy(p<0.01). The Lap group had lesser blood loss(median: 150 mL vs 355 mL, p<0.01)and shorter postoperative hospital stays(median: 8 days vs 11 days, p<0.01). There were no differences in operation time or severe postoperative complications. LRH is feasible and useful, providing good short-term outcomes.
