Abstract

BACKGROUND/AIMS: Many gastrointestinal (GI) endoscopic procedures are difficult and cumbersome owing to the limitation of currently available endoscopic devices. This study aimed to develop an endoscopic guidetube for multipurpose endoscopic procedures and assess its use in a realistic GI endoscopic simulator.

METHODS

The guidetube used is a soft overtube composed of neoprene and is designed to assist various endoscopic procedures on demand. In total, 15 types of procedures were performed in GI simulators. Four procedures were performed in the stomach model and 11 in the colon model. The procedures include repeated endoscopic insertion and foreign body removal in various positions. The mean insertion and procedure time were assessed in each session. All procedures were performed by 5 expert endoscopists.

RESULTS

Endoscopic procedures with the new guidetube were faster and more effective than the conventional endoscopic techniques. The mean insertion time of the endoscope with the guidetube was significantly shorter than that without the guidetube. The guidetube was safely inserted without scratch using low pushing force. Objects of various sizes larger than the endoscopic channel were easily removed by the guidetube-assisted endoscopic procedures.

CONCLUSION

This preliminary study shows that guidetube-assisted endoscopic procedures are faster, easier, safer and cheaper than conventional endoscopic procedures.

摘要

背景/目的：由于现有内镜设备的限制，许多胃肠道（GI）内镜手术操作困难且繁琐。本研究旨在开发一种用于多用途内镜手术的内镜引导管，并在逼真的GI内镜模拟器中评估其应用。

方法

所使用的引导管是一种由氯丁橡胶制成的软性外套管，旨在根据需要协助进行各种内镜手术。在GI模拟器中总共进行了15种类型的手术。在胃模型中进行了4种手术，在结肠模型中进行了11种手术。这些手术包括在不同位置重复内镜插入和异物取出。每次手术均评估了平均插入时间和操作时间。所有手术均由5位内镜专家进行。

结果

使用新型引导管的内镜手术比传统内镜技术更快且更有效。带有引导管的内镜平均插入时间明显短于没有引导管的情况。使用低推力即可安全插入引导管且不会造成刮伤。通过引导管辅助的内镜手术可轻松取出各种尺寸大于内镜通道的物体。

结论

这项初步研究表明，引导管辅助的内镜手术比传统内镜手术更快、更容易、更安全且更便宜。
