Abstract

Background: The impact of obesity on surgical outcomes in elderly patients candidate for liver surgery is still debated.

Aim: To evaluate the impact of high body mass index (BMI) on perioperative and oncological outcome in elderly patients (> 70 years old) treated with laparoscopic liver resection for hepatocellular carcinoma (HCC).

Methods: Retrospective multicenter study including 224 elderly patients (> 70 years old) operated by laparoscopy for HCC (196 with a BMI < 30 and 28 with BMI ≥ 30), observed from January 2009 to January 2019.

Results: After propensity score matching, patients in two groups presented comparable results, in terms of operative time (median range: 200 min vs 205 min, P = 0.7 respectively in non-obese and obese patients), complications rate (22% vs 26%, P = 1.0), length of hospital stay (median range: 4.5 d vs 6.0 d, P = 0.1). There are no significant differences in terms of short- and long-term postoperative results.

Conclusion: The present study showed that BMI did not impact perioperative and oncologic outcomes in elderly patients treated by laparoscopic resection for HCC.
