Trends in bariatric surgery training: bariatric operations performed by Fellowship Council trainees from 2012 to 2019.

Background: The American Society for Metabolic and Bariatric Surgery (ASMBS) Fellowship Certificate was created to ensure satisfactory training and requires a minimum number of anastomotic cases. With laparoscopic sleeve gastrectomy becoming the most common bariatric procedure in the United States, this may present a challenge for fellows to obtain adequate numbers for ASMBS certification.
Objectives: To investigate bariatric fellowship trends from 2012 to 2019, the types, numbers, and approaches of surgical procedures performed by fellows were examined.
Setting: Academic training centers in the United States.
Methods: Data were obtained from Fellowship Council records of all cases performed by fellows in ASMBS-accredited bariatric surgery training programs between 2012 and 2019. A retrospective analysis using standard descriptive statistical methods was performed to investigate trends in total case volume and cases per fellow for common bariatric procedures.
Results: From 2012 to 2019, sleeve gastrectomy cases performed by all Fellowship Council fellows nearly doubled from 6,514 to 12,398, compared with a slight increase for gastric bypass, from 8,486 to 9,204. Looking specifically at bariatric fellowships, the mean number of gastric bypass cases per fellow dropped over time, from 91.1 cases (SD = 46.8) in 2012-2013 to 52.6 (SD = 62.1) in 2018-2019. Mean sleeve gastrectomy cases per fellow increased from 54.7 (SD = 31.5) in 2012-2013 to a peak of 98.6 (SD = 64.3) in 2015-2016. Robotic gastric bypasses also increased from 4% of all cases performed in 2012-2013 to 13.3% in 2018-2019.
Conclusions: Bariatric fellowship training has seen a decrease in gastric bypasses, an increase in sleeve gastrectomies, and an increase in robotic surgery completed by each fellow from 2012 to 2019.
