Technical Feasibility of a Guidetube for Various Endoscopic Procedures in Human Gastrointestinal Simulators: Dong Seok Lee, Byeong Gwan Kim, Kook Lae Lee, Yong Jin Jung, Ji Won Kim; Clin Endosc 2019;52(3):247-251. Published online November 9, 2018; DOI: https://doi.org/10.5946/ce.2018.147

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

Endoscopic Treatment of Foreign Bodies in the Upper Gastrointestinal Tract: Yoon Sae Kang, M.D., Jae Hoon Jung, M.D., Kyung Hoon Chae, M.D., Won Seok Heo, M.D., Yeon Soo Kim, M.D., Seok Hyun Kim, M.D., Jae Kyu Sung, M.D.,Byung Seok Lee, M.D. and Hyun Yong Jeong, M.D.; Korean J Gastrointest Endosc 2005;31(3):135-139.

Abstract PDF: Background
/Aims: The ingestion of foreign bodies in the upper gastrointestinal tract usually happens as a result of accidental swallowing, and rarely produces symptoms. Although most foreign bodies are eliminated spontaneously, 10∼20% of cases need treatment with endoscopy. We evaluated the role of endoscopy for removing foreign bodies from the upper gastrointestinal tract. Methods: We analyzed one hundred and thirty-nine cases of foreign bodies in the upper gastrointestinal tract which were endoscopically treated at Chungnam National University Hospital from January 2001 to July 2004. Results: Patients' age ranged from 6 months to 96 years old (mean 36.0 years old). The ratio of males to females was 1.2：1. The common foreign bodies included coins (29 cases) and fish bones (23 cases), animal bones (19 cases), and stones (15 cases) follows in order. The most common location was the esophagus (79.9%). In most cases (73.4%), the foreign body was removed using an alligator tooth and a grasping forceps. Twenty-eight among one hundred and thirty-nine patients had a co-morbid condition, such as esophageal disease, diabetes mellitus, hypertension, stomach cancer, or a psychiatric disorder. Conclusions: Endoscopic removal is a very powerful and useful method for removing foreign bodies from the upper gastrointestinal tract. Nevertheless, a simpler and more efficient endoscopic equipment is required. (Korean J Gastrointest Endosc 2005;31:135⁣139)
