BackgroundThe MBSAQIP has been used to evaluate risk and create risk models. Previous studies have determined what complications matter most.Study DesignThis study was a registry-based analysis of patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between January 1, 2015, and December 31, 2019, at centers participating in MBSAQIP. Cases were identified using Current Procedural Terminology. Patients less than 18 years old were excluded. A chi-square test was used to assess differences in the prevalence of complications and effects across years. Using a multivariable Poisson regression model with a link log and robust estimation, prevalence ratio estimates and 95% CI were obtained.ResultsA total of 690,770 observations met the inclusion criteria. Mean (SD) age was 44.5 (±12.0) years, and mean (SD) BMI was 45.2 kg/m2 (±7.9). SG cases accounted for 73.45% of all observations. There was a significant relative reduction in readmissions, end-organ dysfunction, and all-cause mortality from 2015 to 2019 in the SG subgroup. There were also noticeable reductions in 30-day readmission, ICU admission, and end-organ dysfunction in the RYGB subgroup. For complications, bleeding, postoperative pneumonia, and stroke were significantly decreased in the RYGB subgroup, but only bleeding was significantly decreased in the SG subgroup during the 5-year study period.ConclusionsThere has been a continuous improvement in several (but not all) outcomes through the years that the MBSAQIP has been collecting data. Different outcomes were reduced between the SG and RYGB subgroups, and the decrease in all-cause mortality was only noted in the SG subgroup.Copyright © 2022 by the American College of Surgeons.
