American Society for Metabolic and Bariatric Surgery 2020 estimate of metabolic and bariatric procedures performed in the United States.
Background: Metabolic and bariatric surgery (MBS), despite being the only effective durable treatment for obesity, remains underused as approximately 1% of all patients who qualify undergo surgery. The American Society for Metabolic and Bariatric Surgery created a Numbers Taskforce to specify annual rate of utilization for obesity treatment interventions and to determine if patients in need are receiving appropriate treatment.
Objective: The objective of this study was to provide the best estimated number of metabolic and bariatric procedures performed in the United States in 2020.
Methods: United States. Methods: We reviewed data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), National Surgical Quality Improvement Program, Bariatric Outcomes Longitudinal Database, and Nationwide Inpatient Sample. In addition, data from industry and state databases were used to estimate activity at nonaccredited centers. Data from 2020 were compared mainly with data from the previous 2 years.
Results: Compared with 2019, the total number of MBS performed in 2020 decreased from approximately 256,000 to 199,000. Sleeve gastrectomy continues to be the most common procedure. The gastric bypass procedure trend remained relatively stable, and the gastric band procedure trend continued to decline. The percentage of revision procedures and biliopancreatic diversion with duodenal switch procedures increased slightly. Single-anastomosis duodeno-ileostomy was listed for the first time in 2020. Intragastric balloons placement declined from the previous year.
Conclusions: There was a 22.5% decrease in MBS volume from 2019 to 2020, which coincided with the COVID-19 pandemic. Sleeve gastrectomy continues to be the dominant procedure, and for the first time, single-anastomosis duodeno-ileostomy is reported in the MBSAQIP database.
