Training for colon capsule endoscopy (CCE) procedures is currently performed as a lecture and hands-on seminar. The aims of this pilot study were to assess the utility of an electronic learning system for CCE (ELCCE) designed for the Japanese Association for Capsule Endoscopy using an objective scoring engine, and to evaluate the efficacy of ELCCE on the acquisition of CCE reading competence.
ELCCE is an Internet-based learning system with the following steps: step 1, introduction; step 2, CCE reading competence assessment test (CCAT), which evaluates the competence of CCE reading prior to training; step 3, learning reading theory; step 4, training with guidance; step 5, training without guidance; step 6, final assessment; and step 7, the same as step 2. The CCAT, step 5 and step 6 were scored automatically according to: lesion detection, diagnosis (location, size, shape of lesion), management recommendations, and quality of view. Ten trainee endoscopists were initially recruited (cohort 1), followed by a validating cohort of 11 trainee endoscopists (cohort 2).
All but one participant finished ELCCE training within 7 weeks. In step 6, accuracy ranged from 53 to 98 % and was not impacted by step 2 pretest scores. The average CCAT scores significantly increased between step 2 pretest and step 7 in both cohorts, from 42 ± 18 % to 79 ± 15 % in cohort 1 (p = 0.0004), and from 52 ± 15 % to 79 ± 14 % in cohort 2 (p = 0.0003).
ELCCE is useful and effective for improving CCE reading competence.
结肠胶囊内镜（CCE）操作培训目前采用讲座和实践研讨会的形式进行。本研究旨在评估一种基于电子学习系统（ELCCE）对 CCE 阅读能力的培训效果，该系统是为日本胶囊内镜协会设计的，使用客观评分引擎。
ELCCE 是一个基于互联网的学习系统，包含以下步骤：步骤 1，介绍；步骤 2，CCE 阅读能力评估测试（CCAT），评估培训前的 CCE 阅读能力；步骤 3，学习阅读理论；步骤 4，指导下的培训；步骤 5，无指导下的培训；步骤 6，最终评估；步骤 7，与步骤 2 相同。CCAT、步骤 5 和步骤 6 会根据病变检出、诊断（病变位置、大小、形状）、管理建议和视野质量进行自动评分。最初招募了 10 名受训内镜医师（队列 1），随后又招募了 11 名受训内镜医师进行验证（队列 2）。
除 1 人外，所有参与者均在 7 周内完成了 ELCCE 培训。在步骤 6 中，准确率在 53%至 98%之间，不受步骤 2 预测试成绩的影响。两个队列的 CCAT 评分在步骤 2 预测试和步骤 7 之间均显著增加，队列 1 从 42%±18%增加至 79%±15%（p=0.0004），队列 2 从 52%±15%增加至 79%±14%（p=0.0003）。
ELCCE 有助于提高 CCE 阅读能力，且效果良好。
