Because of the variability of the colonic anatomy from patient to patient, colonoscopy may be technically difficult to perform and teach, and lesions may be localized inaccurately by the endoscopist. Endoscopists understandably have abandoned fluoroscopy as an adjunct because of its expense, complexity, and potential hazard. The authors have developed a novel method of magnetic imaging that gives real-time views in simulated three dimensions of the endoscope configuration and the location of its tip in the abdomen. The system is inherently safe and easy to use, although it currently requires a catheter to be inserted into the instrumentation channel. Preliminary experience suggests that this approach will be a significant help to endoscopists performing colonoscopy, particularly to those who are currently learning or less experienced.
由于患者之间结肠解剖结构存在差异，结肠镜检查在技术操作和教学方面可能具有难度，并且内镜医师可能无法准确确定病变的位置。由于荧光检查费用高、操作复杂且存在潜在风险，内镜医师放弃将其作为辅助手段，这是可以理解的。作者开发了一种新型磁成像方法，可实时呈现模拟三维视角下的内镜配置及其尖端在腹部的位置。该系统本质上安全且易于使用，尽管目前需要将导管插入器械通道。初步经验表明，这种方法将对进行结肠镜检查的内镜医师有很大帮助，尤其是对那些正在学习或经验较少的医师。
