Learning curve for endoscopic submucosal dissection in early gastric neoplasm using a multibending endoscope.

ABSTRACT:

Background

Endoscopic submucosal dissection (ESD) is a representative treatment modality for early gastric neoplasms. However, the learning curve for beginners performing ESD using a multibending endoscope has not been introduced.

Objective

This study aimed to evaluate the learning curves of operators undergoing intensive training using a multibending endoscope.

Design

This was a retrospective single center study.

Methods

We retrospectively analyzed data of over 1500 consecutive gastric ESDs performed by two operators using a multibending endoscope. A change-point analysis with 50 cases of moving average speeds was used to determine the new target resection speed. Cumulative sum (CUSUM) analysis was used to identify the cases required for proficiency in ESD. Ri
