A single-operator learning curve analysis for the endoscopic sleeve gastroplasty. Academic Article uri icon

Overview

abstract

  • BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) is a novel, incisionless technique for gastric volume reduction to promote weight loss. Our aim was to describe the learning curve for performing ESG using a prospective case series. METHODS: Using a prospective case series design, we analyzed the first 128 consecutive patients at a tertiary care academic medical center who underwent ESG performed by a single operator from August 2013 to December 2016. Efficiency (refining performance to decrease procedure time) and mastery (absence of outliers) for performing ESG was evaluated by using a penalized basis-spline regression and cumulative sum analysis. RESULTS: Efficiency for ESG was attained after 38 ESGs, with mastery after 55 procedures. At 12 months, the mean percent total body weight loss was 15.8% (standard deviation, 9.47%). A total of 71.7% of patients achieved successful weight loss. When using multiple linear regression analysis, both number of sutures and baseline weight were significantly associated with procedure time. Other patient characteristics, such as age, sex, and race, did not significantly affect procedure time. In addition, number of sutures, baseline weight, and endoscopist achieving efficiency were not correlated with successful weight loss at 12 months. CONCLUSIONS: Mastery of ESG by a single operator is suggested after sufficient endoscopic experience and may help guide widespread clinical adaptability.
