Outcomes of robotic surgery in revisional bariatric cases: a propensity score-matched analysis of the MBSAQIP registry

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 i ncidence 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 proced ure 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.
