Abstract: Purpose: Robotic-assisted surgery has become increasingly popular across surgical subspecialties. We aimed to analyze trends in the national utilization and outcomes in bariatric surgery. Materials and Methods: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®) data for 2015-2018 was queried. We included robotic-assisted sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), adjustable gastric band (AGB), biliopancreatic diversion with duodenal switch (BPD-DS), and revisional cases. The Kruskal– Wallis test or Wilcoxon rank-sum were used for comparing continuous variables and Cochran-Armitage trend analysis for categorical variables when comparing years, or with Fisher’s Exact Test when directly comparing categories. Results: Of 760,076 bariatric cases performed between 2015 and 2018, 7.4% with robotic and 90.4% with laparoscopic approach. SG constituted 61.3% of robotic volume. Utilization of robotic surgery increased 1.96-fold; SG represented the most substantial increase of 2.16-fold, followed by a 1.53-fold in RYGB. The 30-day readmission and re-intervention rates decreased from 5.63% to 4.78% (p
