First Experience With The Use Of "Micro Hand S" Surgical Robot In Sleeve Gastrectomy

Background: The Chinese minimally invasive surgical robot system "Micro Hand S" was developed in 2013. However, there was no bariatric surgery performed with the "Micro Hand S" surgical robot. We first aim to report our experience with the "Micro Hand S" robotic-assisted sleeve gastrectomy and evaluate the safety and feasibility of the "Micro Hand S" surgical robot.Methods: Between March 2018 and November 2019, sleeve gastrectomies were performed with the "Micro Hand S" robotic system on 7 consecutive patients by a trained surgeon-assistant team. Preoperative, intraoperative, and postoperative clinical data were collected. A questionnaire was used to investigate surgeons' satisfaction with the "Micro Hand S" robot platform.Results: All the patients underwent successful operations. There were no cases of perioperative mortality and complications. The intraoperative blood loss was 20.8 +/- 3.6 mL. The average overall operating time was 166.4 +/- 16.1 minutes. The weight, body mass index, waist circumference, and hip circumference decreased significantly at 3 months (all P < .01) and 6 months (all P < .01) postoperatively. The percentage excess weight loss was 62.6% +/- 10.3% and 85.9% +/- 13.3% at 3 and 6 months postoperatively. Surgeons were satisfied with the "Micro Hand S" surgical robot performance in sleeve gastrectomy. Eighty percent of surgeons would incline to use it again.Conclusions: The first use of the "Micro Hand S" robotic surgical platform in sleeve gastrectomy was carried out successfully. The perioperative outcomes are satisfying. Further comparative and large-sample studies are warranted to verify our preliminary outcomes.
