摘要

Background

Patients with a BMI (Body Mass Index) ≥ 60 kg/m2 are at high risk for bariatric surgery. They have higher complication rates, longer length of stay and greater technical difficulties with surgery. Surgical robots offer better ergonomics and precision, which facilitate surgery. The role of the robot in patients with obesity class V (BMI ≥ 60 kg/m2) surgery has not been adequately evaluated.

Objectives

This study reports data of over 230,000 patients regarding bariatric surgery. We aim to compare the results of laparoscopic and robotic RYGB in patients with BMI ≥ 60 kg/m2.

Setting

MBSAQIP database.

Methods

Patients aged 18–80 years who underwent Roux-en-Y gastric bypass (RYGB) were included using the 2020–2023 MBSAQIP database. We compared the 30-day outcomes of laparoscopic versus robotic RYGB in patients with BMI < 60 kg/m2 versus BMI ≥ 60 kg/m2.

Results

There are 233,828 patients in this study. Patients with BMI ≥ 60 kg/m2, as compared to BMI < 60 kg/m2, were more likely to have postoperative complications (5,23% vs. 4,44%, p = 0,039), acute renal failure (0,23% vs. 0,07%, p = 0,007), unplanned admission to ICU (1,08% vs. 0,73%, p = 0,029) and Emergency Department visits after discharge (12,38% vs. 11,02%, p = 0,019). There is no difference in 30-day complication rate between laparoscopic and robotic RYGB in patients with BMI ≥ 60 kg/m2.

Conclusions

Patients with BMI ≥ 60 kg/m2 have higher rates of complications compared to patients with BMI < 60 kg/m2. RRYGB seems to be a safe to perform in patients with BMI ≥ 60 kg/m2 with no difference in 30-day complication rate, longer average operating time but shorter length of stay. There is still a need for good quality multi-centre prospective research study to define the best approach for patients with obesity class V.
