The impact of liver transection depth on surgical difficulty in robotic versus laparoscopic limited liver resection (TAKUMI-5).

ABSTRACT:

Purpose

Although robotic liver resection (RLR) has gained popularity worldwide, limited liver resection remains the mainstay of RLR. This study aimed to investigate the effect of parameters, including liver transection depth (LTD), on surgical difficulty in limited RLR compared with limited laparoscopic liver resection (LLR).

Methods

This retrospective study included 105 patients who underwent limited RLR (n = 56) or LLR (n = 49) at our institution between January 2018 and December 2024. After comparing outcomes of RLR and LLR, multivariate analyses were performed to examine effect of LTD on surgical difficulty (defined as prolonged operative time). Moreover, outcomes stratified by LTD cut-off values were compared between the groups.

Results

Median LTD was similar bet
