Popis: There is few study evaluating the relationship between endoscopic submucosal dissection (ESD) resection speed and the lesion characteristics of gastric neoplasia. We investigated the learning curve of consecutive ESDs using cumulative sum (CUSUM) analysis.A total of 356 ESDs performed by a single endoscopist were grouped chronologically into three learning periods. The ESD procedure was defined to be fast when resection speed was 9.0 cmMean resection speed was significantly faster in Phase III (15.1 cmThe time required to achieve relevant competency in gastric ESD depends on the tumor location.
