Background/Aims: Many gastrointestinal (GI) endoscopic procedures are difficult and cumbersome owing to the limitation ofcurrently available endoscopic devices. This study aimed to develop an endoscopic guidetube for multipurpose endoscopic proceduresand 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 ondemand. In total, 15 types of procedures were performed in GI simulators. Four procedures were performed in the stomach model and11 in the colon model. The procedures include repeated endoscopic insertion and foreign body removal in various positions. The meaninsertion 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 guidetubewas safely inserted without scratch using low pushing force. Objects of various sizes larger than the endoscopic channel were easilyremoved by the guidetube-assisted endoscopic procedures. Conclusions: This preliminary study shows that guidetube-assisted endoscopic procedures are faster, easier, safer and cheaper thanconventional endoscopic procedures.
