Abstract

In recent years, there has been a significant increase in the number of Revisional Bariatric Surgery (RBS) cases performed to address complications and weight recidivism. The use of the da Vinci robotic platform, considered controversial by many, may offer advantages in RBS. The objective of our study is to compare the outcomes of Robotic RBS (R-RBS) to Laparoscopic RBS (L-RBS). Using the 2015-2017 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, we selected all RBS and we matched R-RBS to L-RBS using a propensity score matching system to create balanced groups. Our primary outcomes were 30-day Serious Adverse Events (SAE), 30-day Organ Specific Infection (OSI), 30-day reoperation and 30-day interventions. Our secondary outcomes included length of operation and 30-day readmission. We conducted separate Mann-Whitney rank sums tests or chi-square tests and Fisher exact test. R-RBS and L-RBS included 220 patients each. The overall incidence of 30-day SAEs, 30-day OSIs, 30-day reoperations, 30-day interventions were lower for R-RBS (6.4%, 0.9%, 2.7% and 2.3%, respectively) compared L-RBS (7.7%, 1.4%, 3.6% and 3.6%, respectively). Subgroup analysis showed that R-RBS had a lower rate of complications for the Gastric Bypass procedure but not for Sleeve gastrectomy cases. However, 30-day readmission was higher for R-RBS compared to L-RBS (9.1% vs 6.4% respectively). None of the analyses reached statistical significance. R-RBS took significantly longer compared to L-RBS (169 min vs 138 min, p < 0.05). Our study shows that R-RBS has lower complication rate albeit non-significant as compared to L-RBS.
