## Key findings

- RABS using the Versius® system showed a manageable learning curve with docking time decreasing from 17 to 7 minutes.
- The six-month morbidity rate was 1.5% (Clavien-Dindo Grade I–IIIb) with no conversions to open surgery.
- The study confirms the safety and reproducibility of robotic-assisted bariatric surgery in an emerging healthcare setting.

## Abstract

Robotic assistance has been increasingly incorporated into bariatric surgery. However, data regarding newer modular robotic-assisted platforms such as the Versius® Surgical Robotic System remain limited, particularly in developing healthcare settings. To evaluate the feasibility, safety, and short-term outcomes of robotic-assisted bariatric surgery (RABS) using the Versius® system in a high-volume bariatric center. A retrospective analysis was conducted on 200 robotic-assisted bariatric procedures performed between December 2021 and December 2024. Procedures included primary and revisional bariatric operations. The Versius® system was used as a robotic-assisted platform, with laparoscopic stapling, energy devices, and suction performed through an assistant port. Demographic data, operative metrics, complications, length of stay, and six-month postoperative outcomes were analyzed descriptively. The mean BMI was 43.85 ± 6.7 kg/m². Procedures included Sleeve Gastrectomy (n = 132), One-Anastomosis Gastric Bypass (n = 25), Roux-en-Y Gastric Bypass (n = 22), and Revisional Surgery (n = 21). Docking time decreased from 17 to 7 min, and console time stabilized after 30–40 cases. There were no conversions to open or laparoscopic surgery. The six-month morbidity rate was 1.5% (Clavien-Dindo Grade I–IIIb). RABS using the Versius® platform is safe and feasible in this series, demonstrating a manageable learning curve. While the platform is adoptable in emerging healthcare settings, comparative studies are required to establish its clinical and cost advantages over standard laparoscopy.
