ARTICLE HIGHLIGHTS
Research background

Laparoscopic liver surgery is considered the standard of care for various liver malignancies. However, several studies have reported an increased risk of technical difficulties during surgery and the frequent occurrence of postoperative complications in overweight and obese patients.

Research motivation

Studies focusing on perioperative outcome after laparoscopic hepatectomy in overweight patients are still sparse and its benefit compared to open hepatectomy is a matter of debate.

Research objectives

The aim of this study was to analyze postoperative outcomes in overweight (BMI ≥ 25 kg/m²) and obese (BMI ≥ 30 kg/m²) patients undergoing laparoscopic hepatectomy and compare postoperative outcomes with patients undergoing conventional open resection.

Research methods

Perioperative data of 68 overweight and obese patients who underwent laparoscopic hepatectomy at our institution between 2015 and 2019 were retrospectively analyzed regarding surgical outcome and compared to an equal number of patients undergoing open hepatectomy. The postoperative course was reviewed for complications and rated according to the Clavien-Dindo classification and quantified using the Comprehensive Complication Index.

Research results

We provide evidence that overweight patients undergoing laparoscopic hepatectomy have significantly fewer postoperative complications and reduced intensive care stay as well as overall hospitalization without increased overall costs.

Research conclusions

We conclude that laparoscopic hepatectomy is safe and cost-effective in overweight and obese patients. Additionally, this technique is significantly associated with fewer postoperative complications and reduced hospital stay compared to open hepatectomy in these patients.

Research perspectives

Additional research is needed to prospectively confirm our results and to evaluate outcomes in a larger and more balanced cohort to reach a definitive conclusion. Particularly in obese patients with a BMI above 30 kg/m², technical difficulties could be a factor in larger cohorts, which then become apparent.
