Early Experience with Totally Robotic Roux-en-Y Gastric Bypass for Morbid Obesity

摘要

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (RYGBP) for morbid obesity is a challenging operation. The application of robotic techniques has been shown to ease the technical difficulties and reduce perioperative morbidity, mainly because it facilitates the construction of the gastrojejunal anastomosis (GJ). Robotic laparoscopic RYGBP (LRYGBP) has been reported either as totally robotic with manual suturing of the GJ or as robotically assisted with the use of the robot only for the construction of the GJ. A totally robotic LRYGBP with a combined stapled and manual GJ has never been reported. PATIENTS AND METHODS: Nine consecutive patients underwent totally robotic LRYGBP. The GJ was fashioned with a combination of the linear stapler and manual suturing. RESULTS: Mean preoperative body mass index was 45.3 ± 4.7 kg/m(2). In 1 case, we had to undock the Da Vinci Surgical System at the time of the jejunojejunostomy due to unfavorable ergonomics. Mean time to dock the robot was 16.3 ± 3.3 minutes, whereas mean total operative time was 197.2 ± 12.3 minutes. Immediate postoperative morbidity and mortality equaled zero. One patient developed a stenosis of the GJ amenable to endoscopic dilatation. The mean excess weight loss rate 1-year postoperative was 79% ± 15%. CONCLUSION: Totally robotic LRYGBP can duplicate precisely any conventional technique without any compromise in operative time, short- or long-term results.
