These techniques are widely used in Eastern countries; however, its use in the West is limited. The aim of this study was to evaluate the current implementation of ESD in Western countries. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; Western endoscopists (&lt;i&gt;n&lt;\/i&gt; = 279) who published papers related to EMR\/ESD between 2005 and 2017 were asked to complete an online survey from December 2017 to February 2018. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; A total of 58 endoscopists (21%) completed the survey. Thirty performed ESD in the esophagus (52%), 45 in the stomach (78%), 36 in the co\u00adlorectum (62%), and 6 in the duodenum (10%). The median total number of lesions ever treated per endoscopist was 190, with a median number per endoscopist in 2016 of 41 (7 [IQR 1\u201321], 6 [IQR 4\u201316], and 28 [5\u201363] in the esophagus, in the stomach, and in the colon and rectum, respectively). En bloc resection rates were 97% in the esophagus, 95% in the stomach, and 84% in the colorectum. Complete resection (R0) was achieved in 88, 91, and 81%, respectively. Curative rates were 69, 70, and 67%, respectively. Major complications (perforation or delayed bleeding) occurred more often in colorectal ESD (12 vs. 6% in the esophagus and 7% in the stomach). In the upper GI tract, the majority of resected lesions were intramucosal adenocarcinoma (59% in the esophagus; 47% in the stomach), while in the colorectum the majority were adenomas (59%). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; ESD seems to be performed by a large number of centers and endoscopists. Our results suggest that ESD is being successfully implemented in Western countries, achieving a good rate of efficacy and safety according to European guidelines.<\/jats:p>","DOI":"10.1159\/000501404","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T21:02:08Z","timestamp":1569272528000},"page":"1-17","source":"Crossref","is-referenced-by-count":13,"title":["How Is Endoscopic Submucosal Dissection for Gastrointestinal Lesions Being Implemented?
