Evaluating pneumoperitoneum pressure in robotic liver surgery: a propensity-score matched analysis in a high-volume center in Scandinavia.

ABSTRACT:

Background

Minimally invasive liver surgery usually involves the use of standard pneumoperitoneal pressure (12-15 mmHg) and low central venous pressure (CVP) management to reduce intraoperative bleeding while hereby possibly increasing the risk for gas embolism. The purpose of this study is to evaluate the efficacy and safety of low pneumoperitoneum pressure (Low-PP: 10 mmHg) compared to standard pneumoperitoneum pressure (Standard-PP: 12 mmHg) in patients undergoing robotic liver surgery (RLS) without active CVP management.

Methods

A single-center retrospective cohort study was conducted from June 2019 to February 2024. Propensity-score matching analysis (1:1) was performed based on age, sex, BMI, ASA classification, diagnosis, and extent of resection (minor or major) for L
