Sensitivity and inter-observer variability for capsule endoscopy image analysis in a cohort of novice readers

瞄准：为检测囊内视镜检查法调查结果决定新手阅读器(第 4 个年医学院的学生) 的性能。方法：小肠损害的十个囊内视镜检查法盒子予读者被以。标准答案调查结果被胃的肠学预先规定。十个标准答案“目标”在 10 个盒子之中被识别。读者们被给快速的读者软件的 30-min 概述并且指示标记畸形的任何潜在的区域。一个软件程序用 SAS 被开发分析缩小的调查结果。结果：为检测标准答案调查结果的全面敏感是 80% 。作为一个组，至少 5 从 10 个读者检测了每记录发现的每个标准答案。当读者的结果被联合时，所有标准答案目标被识别。偶然的 finding/false 积极的率每读者在 8.2-59.8 之间变化了。结论：有最小的内视镜的经验的医学院的学生的一块面板能在在囊内视镜检查法上检测损害完成高敏感。一组新手读者能预先屏蔽为进一步的评论缩小小肠损害的潜在的区域的记录。这些指图必须被考察决定临床的关联。进一步的研究是进行中的估计另外的队。

AIM： To determine the performance of novice readers （4^th year medical students） for detecting capsule endoscopy findings. METHODS： Ten capsule endoscopy cases of small bowel lesions were administered to the readers. Gold standard findings were pre-defined by gastroenterologists. Ten gold standard ＂targets＂ were identified among the 10 cases. Readers were given a 30-min overview of Rapid Reader software and instructed to mark any potential areas of abnormalities. A software program was developed using SAS to analyze the thumbnailed findings. RESULTS： The overall sensitivity for detecting the gold standard findings was 80%. As a group, at least 5 out of 10 readers detected each gold standard finding per recording. All the gold standard targets were identified when the readers＇ results were combined. Incidental finding/false positive rate ranged between 8.2-59.8 per reader. CONCLUSION： A panel of medical students with minimal endoscopic experience can achieve high sensitivity in detecting lesions on capsule endoscopy. A group of novice readers can pre-screen recordings to thumbnail potential areas of small bowel lesions for further review. These thumbnails must be reviewed to determine the clinical relevance. Further studies are ongoing to assess other cohorts.
