Abstract
The impact of obesity on surgical outcomes in elderly patients candidate for liver surgery is still debated. 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). 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. 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. The present study showed that BMI did not impact perioperative and oncologic outcomes in elderly patients treated by laparoscopic resection for HCC.
