Colon capsule endoscopy (CCE) was developed for the evaluation of colorectal pathology. In this study, our aim was to assess if a dual-camera analysis using CCE allows better evaluation of the whole gastrointestinal (GI) tract compared to a single-camera analysis.
We included 21 patients (12 males, mean age 56.20 years) submitted for a CCE examination. After standard colon preparation, the colon capsule endoscope (PillCam Colon™) was swallowed after reinitiation from its "sleep" mode. Four physicians performed the analysis: two reviewed both video streams at the same time (dual-camera analysis); one analyzed images from one side of the device ("camera 1"); and the other reviewed the opposite side ("camera 2"). We compared numbers of findings from different parts of the entire GI tract and level of agreement among reviewers.
A complete evaluation of the GI tract was possible in all patients. Dual-camera analysis provided 16% and 5% more findings compared to camera 1 and camera 2 analysis, respectively. Overall agreement was 62.7% (kappa = 0.44, 95% CI: 0.373-0.510). Esophageal (kappa = 0.611) and colorectal (kappa = 0.595) findings had a good level of agreement, while small bowel (kappa = 0.405) showed moderate agreement.
The use of dual-camera analysis with CCE for the evaluation of the GI tract is feasible and detects more abnormalities when compared with single-camera analysis.
结肠胶囊内镜检查（CCE）是为评估结直肠病变而开发的。在本研究中，我们的目的是评估与单摄像头分析相比，使用CCE进行双摄像头分析是否能更好地评估整个胃肠道（GI）。
我们纳入了21例接受CCE检查的患者（12例男性，平均年龄56.20岁）。在进行标准的结肠准备后，结肠胶囊内镜（PillCam Colon™）从“睡眠”模式重新启动后被患者吞下。四名医生进行分析：两名医生同时查看两个视频流（双摄像头分析）；一名医生分析设备一侧的图像（“摄像头1”）；另一名医生查看另一侧的图像（“摄像头2”）。我们比较了整个胃肠道不同部位的发现数量以及审阅者之间的一致性水平。
所有患者均能对胃肠道进行完整评估。与摄像头1和摄像头2分析相比，双摄像头分析分别多发现了16%和5%的病变。总体一致性为62.7%（kappa = 0.44，95% CI：0.373 - 0.510）。食管（kappa = 0.611）和结直肠（kappa = 0.595）的发现一致性良好，而小肠（kappa = 0.405）的一致性为中等。
使用CCE双摄像头分析评估胃肠道是可行的，并且与单摄像头分析相比能检测到更多异常。
