Improving Operating Room Efficiency of Robotic-Assisted Metabolic and Bariatric Surgery Through Standardization.

INTRODUCTION: The use of robotic-assisted (RA) surgery in the field of metabolic and bariatric surgery (MBS) is controversial because of cost concerns and issues related to efficiency. The objective of this study is to evaluate the operating room efficiency in performing RA-MBS prior and after the implementation of a standardized surgical approach. MATERIALS AND METHODS: All MBS cases entered into our database between October 2017 and October 2022 were collected and analyzed before and after the introduction of the standardized approach (SA). The outcome variables consisted of operation time (OT), turnover time (TT), wheels in-wheels out (WW), and console time (CT). Procedures were divided into Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and revisional bariatric surgery (RBS). RESULTS: For RYGB (n = 185), we found a significant reduction in OT, TT, and WW after SA (129 min vs 139 min; 37 min vs 73 min; 165 min vs 175 min, respectively, p < 0.05). For SG (n = 253), we found a significant reduction in turnover time (TT) after SA. For RBS (n = 201), we also found a significant reduction in OT, TT, WW, and CT after SA ( 157 min vs 177 min; 36 min vs 72 min; 194 min vs 216 min; 119 min vs 134 min, respectively, p < 0.05). CONCLUSION: Using a standardized surgical approach, we were able to demonstrate improved operation room efficiency as demonstrated by a reduction in operation length, turnover time, and the overall time of the procedure for primary RYGB and revisional procedures and turnover time for primary sleeve procedures.

Outcomes of Staple Line Reinforcement Following Robotic Assisted Sleeve Gastrectomy Based on MBSAQIP Database.

INTRODUCTION: The objective of this study is to evaluate the outcomes for Staple Line Reinforcement (SLR) in RA-SG based on the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for 2019. MATERIALS AND METHODS: We selected patients who underwent RA-SG in the MBSAQIP PUF (Public Utility File) for the year 2019 and grouped them based on their SLR status: Oversewing (OS), Buttressing (BR), both OS and BR and neither. Our primary outcomes were bleeding, organ space infection (OSI), and adverse events (AEs), and our secondary outcomes were operation length, hospital length of stay, readmissions, and conversion to open rates. We conducted separate chi square or one-way analysis of variance (ANOVA) as appropriate and multivariable direct logistic regression models for the categorical outcomes. RESULTS: We found 115,621 patients with complete data of which there were 16,494 who underwent RA-SG. Our results did not show a statistically significant decrease in incidence of postoperative bleeding for BR and OS (Adjusted OR = 0.782, p = 0.2291 and Adjusted OR of 0.482, p = 0.054 for BR and OS respectively). There was a statistically significant effect for SLR status on operation length, with OS patients having the highest operative times (log-transformed mean = 2.03), followed by both BR + OS patients (log-transformed mean = 1.99). BR patients had the shortest operation length. CONCLUSION: SLR did not result in any significant differences related to bleeding, OSI or AEs following RA-SG according to MBSAQIP for the year 2019. However, OS resulted in significantly longer operative time compared to BR alone.
