Abstract
Introduction: The aim of our work was to assess the impact of high BMI on perioperative and oncological outcome in elderly patients (> 70 years old) treated with laparoscopic liver resection for hepatocellular carcinoma (HCC). Method: 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: The operating time (200 vs. 220, p = 0.7), the transfusion rate (16% vs. 3%, p = 0.09) and the length of hospitalization (6 vs. 5.5, p = 0.2) are similar in the two groups. Patients with a BMI> 30 have a significantly higher complication rate (47% vs 25%, p = 0.02), but only related to the percentage of surgical site infections (SSI). There are no significant differences in terms of short and long term postoperative results. Conclusions: Despite a higher rate of SSI in obese patients, BMI does not appear to have an impact on perioperative and oncologic outcomes in elderly patients treated by laparoscopic resection for HCC.
