Despite colonoscopy represents the conventional diagnostic tool for colorectal pathology, its undeniable discomfort reduces compliance to screening programmes.
To evaluate feasibility and accuracy of a novel robotically-driven magnetic capsule for colonoscopy as compared to the traditional technique.
Eleven experts and eleven trainees performed complete colonoscopy by robotic magnetic capsule and by conventional colonoscope in a phantom ex vivo model (artificially clean swine bowel). Feasibility, overall accuracy to detect installed pins, procedure elapsed time and intuitiveness were measured for both techniques in both operator groups.
Complete colonoscopy was feasible in all cases with both techniques. Overall 544/672 pins (80.9%) were detected by experimental capsule procedure, while 591/689 pins (85.8%) were detected within conventional colonoscopy procedure (P=ns), thus establishing non-inferiority. With the experimental capsule procedure, experts detected 74.2% of pins vs. 87.6% detected by trainees (P<0.0001). Overall time to complete colon inspection by robotic capsule was significantly higher than by conventional colonoscopy (556±188s vs. 194±158s, respectively; P=0.0001).
With the limitations represented by an ex vivo setting (artificially clean swine bowel and the absence of peristalsis), colonoscopy by this novel robotically-driven capsule resulted feasible and showed adequate accuracy compared to conventional colonoscopy.
尽管结肠镜检查是结直肠病理学的常规诊断工具，但不可否认的是其带来的不适降低了人们对筛查计划的依从性。
评估新型机器人驱动的磁胶囊结肠镜检查与传统技术相比的可行性和准确性。
11 名专家和 11 名学员在一个模拟的离体模型（人工清洁的猪肠）中使用机器人磁胶囊和传统结肠镜进行了完整的结肠镜检查。在两个操作人员组中，对两种技术的可行性、检测安装销钉的总体准确性、操作时间和直观性进行了测量。
两种技术在所有病例中均能完成完整的结肠镜检查。在实验胶囊检查过程中，总共检测到 544/672 个销钉（80.9%），而在传统结肠镜检查过程中，总共检测到 591/689 个销钉（85.8%）（P=ns），从而确立了非劣效性。在实验胶囊检查过程中，专家检测到 74.2%的销钉，而学员检测到 87.6%的销钉（P<0.0001）。使用机器人胶囊完成整个结肠检查的总时间明显长于传统结肠镜检查（分别为 556±188s 和 194±158s；P=0.0001）。
在离体设置（人工清洁的猪肠和缺乏蠕动）的限制下，这种新型机器人驱动的胶囊结肠镜检查是可行的，与传统结肠镜检查相比，具有足够的准确性。
