Robotic Versus Laparoscopic Roux-en-Y-Gastric Bypass: A Retrospective Study in a Single Center

Abstract

BACKGROUND: Bariatric surgery is the best treatment option for patients with obesity. As a result of the advancement of technology, the robotic gastric bypass presents promising results, despite its still high costs. AIMS: The aim of this study was to compare patients submitted to a robotic versus a laparoscopic gastric bypass at a single center by a single surgeon. METHODS: This retrospective study collected data from the medical records of 221 patients (121 laparoscopic procedures versus 100 with daVinci platform). The variables analyzed were sex, age, body mass index, comorbidities, surgical time, length of stay, and complications. RESULTS: The mean surgical time for patients in the robotic group was shorter (102.41±39.44 min versus 113.86±39.03 min, p=0.018). The length of hospital stay in robotic patients was shorter (34.12±20.59 h versus 34.93±11.74 h, p=0.007). There were no serious complications. CONCLUSIONS: The group submitted to the robotic method had a shorter surgical time and a shorter hospital stay. No difference was found regarding strictures, bleeding, or leakage.
