Abstract

Background: The advantages of laparoscopic liver resection (LLR) have increased its use for the treatment of benign liver tumors (BLTs). Objective: The aim of this study was to compare the perioperative outcomes of patients undergoing LLR with those operated on with open liver resection (OLR) for BLTs using propensity score matching (PSM). Material and methods: We conducted a descriptive and retrospective study comparing OLRs with LLRs performed between August 2010 and June 2021. The demographic, perioperative, intraoperative and postoperative variables were analyzed. We used PSM with 1:1 matching to avoid biases of the different covariates between the groups. Results: Of 303 liver resections, 82 corresponded to BLTs and were included in the analysis; 36 (44%) were OLRs and 46 (56%) were LLRs. Mean age was 45 ±14 years and 65% were women. After PSM, two groups of 28 patients each were constituted. Five patients (18%) in the OLR group and none in the LLR required transfusions (p = 0.01). Major complications, occurred in 4 (14%) patients in the OLR group and in no cases in the LLR group (p = 0.03). Four (14%) undergoing OLR required reoperation versus no patients with LLR (p = 0.03). Total length of hospital stay was significantly longer in OLR (p = 0.04). There were no deaths in any of the groups within 90 days. Conclusion: LLR for BLTs is a safe and effective technique, with lower requirement for transfusions, fewer reoperations and major complications and shorter length of hospital stay than OLR, Therefore, LLR could be considered the surgical technique of choice for BLTs.
