BackgroundPerioperative short-term outcomes could be improved after totally robotic Roux-en-Y gastric bypass (TR-RYGBP) compared with conventional laparoscopic gastric bypass.MethodsThis is a nonrandomized controlled prospective study (N = 200) to evaluate perioperative short-term outcomes. The primary endpoint was to investigate risk factors for 30-day surgical complications.ResultsMean total operative time was shorter in patients who underwent TR-RYGBP (130 vs 147 minutes; P < .0001). However, postoperative surgical complications rate (13% vs 1%; P = .001), and mean overall hospital stay (9.3 vs 6.7 days; P < .0001) were higher after TR-RYGBP. By multivariate analysis, robotic surgery (hazard ratio [HR] = 15.1; 95% confidence interval [CI], 2.8 to 280; P = .01), and conversion to laparotomy (HR = 18.8; 95% CI, 1.7 to 250.8; P = .014) were independent risk factors for 30-day surgical complications.ConclusionsAlthough robotic gastric bypass reduces mean operative time, TR-RYGBP is associated with an increased postoperative surgical complications rate and longer hospitalization.Copyright © 2013 Elsevier Inc.
