The early clinical results are described of a real time, electromagnetic imaging system as an aid to colonoscopy. After gaining experience with the use of the system, one experienced endoscopist was randomised to perform consecutive colonoscopies either with (n = 29) or without (n = 26) the imager view. All procedures were recorded on computer disk and replayed for retrospective analysis. Total colonoscopy was achieved in all patients except one (imager view not available). Comparing intubation time and duration of loop formation per patient, there was no significant difference between the two study groups. The number of attempts taken to straighten the colonoscope pre patient, however, was less when the endoscopist was able to see the imager view, p = 0.03. Hand pressure was also more effective when the endoscopist and endoscopy assistant could see the imager display, p = 0.02. Preliminary experience suggests that real time, electronic imaging of colonoscopy is safe, effective, and will improve the accuracy of the procedure.
本文描述了一种用于辅助结肠镜检查的实时电磁成像系统的早期临床结果。在积累了使用该系统的经验后，一名经验丰富的内镜医师被随机分配，分别在有（n = 29）或无（成像视图不可用）成像器视图的情况下连续进行结肠镜检查。所有操作均记录在计算机磁盘上，并回放以供回顾性分析。除一名患者外（无成像器视图），所有患者均完成了全结肠镜检查。比较每位患者的插管时间和肠袢形成持续时间，两个研究组之间无显著差异。然而，当内镜医师能够看到成像器视图时，在患者前拉直结肠镜所需的尝试次数较少，p = 0.03。当内镜医师和内镜助手能够看到成像器显示屏时，手动按压也更有效，p = 0.02。初步经验表明，结肠镜检查的实时电子成像安全、有效，且将提高该操作的准确性。
