As a follow up on our yearly estimation of the total number of bariatric cases in the U.S., we are now presenting the 2015 data.

The ASMBS Bariatric Numbers Taskforce followed the same methodology as in the past1. A comprehensive review of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed, which included 100% of the primary and revisional bariatric cases performed within accredited metabolic and bariatric surgery centers.

It is noted that 89 new centers submitted data in 2015 compared to the year before and these centers submitted data on 8,110 cases. These new accredited centers made the estimation on the number of cases performed in inpatient non-accredited facilities drop to more than half of what was estimated in 2014. Bariatric Outcomes Longitudinal Database (BOLD) and other databases were reviewed as well.

To capture outpatient procedures performed at centers that do not submit data to MBSAQIP or BOLD, device makers were surveyed to obtain the total number of gastric bands and intragastric balloons sold per year; large outpatient centers performing stapling procedures, mainly laparoscopic sleeve gastrectomies, were also surveyed. Estimated deductions on devices purchased but not used were made.

The 2015 numbers showed stability in the total number of procedures compared to 2014. The sleeve gastrectomy continues to be the most common procedure. Continuing the same trends as previous years, the gastric bypass decreased some and the gastric band decreased significantly more. Number of revisions now are close to 1 out of 7 cases performed, predominantly being gastric band conversions to stapling procedures.
