Early experience with totally laparoscopic major hepatectomies: single institution experience with 31 consecutive...

Totally laparoscopic major hepatectomy (LMH) is a technically challenging procedure with limited studies mainly from high-volume expert centers reported. In this study, we report our initial experience with totally LMH.

A retrospective review of a prospective database of 340 consecutive patients who underwent laparoscopic liver resection at a single institution was conducted. Thirty-one consecutive patients who underwent attempted totally LMH between March 2011 to December 2016 were identified. Major hepatectomies were defined as resection of ≥3 contiguous segments which included only right/left hepatectomies, extended hepatectomies or central hepatectomies.

The procedures included 11 right hepatectomies, one extended right hepatectomy, nine left hepatectomies (two including middle hepatic vein), two extended left hepatectomies, two left hepatectomies with caudate lobe and six central hepatectomies. The median tumor size was 40 (range, 12-100) mm and the median operation time was 435 (range, 245-585) min. Median blood loss was 500 (range, 100-1900) mls and 10 (32.3%) patients required blood transfusion. There were three (9.7%) open conversions of which two occurred during the first five cases. There was one (3.2%) major (>grade 2) morbidity and there were no 30-day/in-hospital mortalities or reoperations. The median postoperative stay was 5 (range, 3-14) days.

Our initial experience confirms the feasibility and safety of LMH. There was an increase in the number and proportion of LMH performed at our institution over time.
