Abstract

•This study aimed to assess the learning curve effect on patient's clinical outcome for EESD. Retrospective observational study, enrolling patients that underwent EESD from 2009 to 2021, divided in 2 groups. Mean procedure time was 111.8 min and 103.6 min for T1 and T2, respectively (P=0.004). The learning curve in esophageal ESD could be overcomed effectively and safely by an adequately trained Western endoscopist. Background - Esophageal endoscopic submucosal dissection (EESD) is a complex and time-consuming procedure at which training are mainly available in Japan. There is a paucity of data concerning the learning curve to master EESD by Western endoscopists. Objective - This study aimed to assess the learning curve effect on patient's clinical outcome for EESD. Methods - This is a retrospective observational study. Enrolling patients that underwent EESD from 2009 to 2021. The analysis was divided into two periods; T1: case 1 to 49 and T2: case 50 to 98. The following features were analyzed for each group: patients and tumors characteristics, en-bloc, complete and curative resection rates, procedure duration and adverse events rate. Results - Ninety-eight EESD procedures were performed. Mean procedure time was 111.8 min and 103.6 min for T1 and T2, respectively (P=0.004). En bloc resection rate was 93.8% and 97.9% for T1 and T2, respectively (P=0.307). Complete resection rate was 79.5% and 85.7% for T1 and T2, respectively (P=0.424). Curative resection rate was 65.3% and 71.4% for T1 and T2, respectively (P=0.258). Four patients had complications; three during T1 period and one during T2 period. Overall mortality rate: 0%. Conclusion - The esophageal endoscopic submucosal dissection could be performed effectively and safely by an adequately trained Western endoscopist.

日本培训的西方内镜医师在食管内镜下黏膜下剥离术中的学习曲线:拉丁美洲的经验。
•本研究旨在评估学习曲线对EESD患者临床结果的影响。回顾性观察性研究,纳入2009年至2021年接受EESD的患者,分为2组。T1和T2的平均手术时间分别为111.8分钟和103.6分钟(P=0.004)。经过充分培训的西方内镜医生可以有效、安全地克服食管ESD的学习曲线。背景-食道内窥镜黏膜下剥离术(EESD)是一种复杂而耗时的手术,在日本主要接受培训。西方内窥镜医生掌握EESD的学习曲线数据很少。目的:本研究旨在评估学习曲线对EESD患者临床结果的影响。方法——这是一项回顾性观察性研究。纳入2009年至2021年接受EESD的患者。分析分为两个阶段;T1:情况1至49,T2:情况50至98。分析各组的以下特征:患者和肿瘤特征、整体切除率、完全切除率和治愈率、手术持续时间和不良事件率。结果-共进行了98次EESD手术。T1和T2的平均手术时间分别为111.8分钟和103.6分钟(P=0.004)。整体切除率T1和T2分别为93.8%和97.9%(P=0.007)。T1和T2完全切除率分别为79.5%和85.7%(P=0.424)。T1或T2的根治性切除率分别是65.3%和71.4%(P=0.258)。4名患者出现并发症;三个在T1期间,一个在T2期间。总死亡率:0%。结论:经充分培训的西方内镜医生可以有效、安全地进行食道内镜下黏膜下剥离术。
