摘要

Purpose

We aimed to investigate the differences in surgical difficulty between laparoscopic partial liver resections of segments 7 and 8.

Methods

We analyzed 173 patients who underwent partial liver resections of segments 7 or 8 between 2010 and 2022 at two institutions. We investigated differences in the surgical outcomes of each procedure using propensity score matching. We compared these outcomes with those of open partial liver resections for segments 7 and 8 to determine whether the differences were unique to the laparoscopic approach.

Results

Thirty and 54 patients underwent laparoscopic partial liver resections of segments 7 and 8. In the matched cohort (22 in each group), the operation time was significantly longer (377 vs. 278 min, P = 0.020) and the proportion of postoperative complications significantly higher in segment 7 (27% vs. 0%, P = 0.008). Forty-one and 48 patients underwent open partial liver resections of segments 7 and 8, respectively. There were no significant differences in the surgical outcomes between the segments in the matched cohort (20 in each group).

Conclusions

Laparoscopic partial liver resections of segment 7 may be more challenging than that of segment 8. This difference in difficulty was not observed in open partial liver resections.
