Abstract

BACKGROUND/AIMS
Telemedicine is a convenient and efficient tool for remote education in various fields. The telemedicine system can also be used to educate doctors and medical students. The aim of our study was to establish the effectiveness of the telemedical system for use in a live endoscopic multichannel demonstration conference and to test the effectiveness and usefulness of a multicenter-based live endoscopic demonstration through live, interactive, high resolution video transmission using advanced networks and the digital video transport system (DVTS).
METHODS
This study is a prospective multicenter pilot study. A live demonstration of an endoscopic submucosal dissection (ESD) and an endoscopic retrograde cholangiopancreatography (ERCP) using advanced network technology was performed.
RESULTS
The DVTS successfully transmitted uncompressed, high-resolution, digital lectures with endoscopy video during a multichannel endoscopic live demonstration of ESD and ERCP over multiple advanced networks. The overall satisfaction rating when the endoscopic lecture demonstration was performed by combining DVTS was generally good.
CONCLUSIONS
We believe that a multicenter-based live endoscopic demonstration is a very effective conferencing method when using advanced networks and DVTS.

ESD procedures that were being performed at Hanyang University Medical Center (HMC), Chungbuk National University Hospital (CBNUH), Chunbuk National University Hospital (CNUH), Soonchunhyang University Hospital (SCHU), and Kyoto Red Cross Hospital (KRCH) in Japan were transmitted to the GHH in Seoul, Korea.

These trainees and the senior person present in the conference room discuss ESD skills and knowledge with the doctors who are performing the remote ESD live demonstration.

A thousand Korean endoscopists gathered inside the Hanyang University Paiknam Academic Informative Center (HUPAIC) located in Seoul, Korea. ERCP procedures performed at Hanyang University Medical Center (HMC), Asan Medical Center (AMC), Korea University Hospital (KUH), Seoul National University Budang Hospital (SNUBH), Ajou University Hospital (AJUH), Chungbuk National University Hospital (CBNUH), Chunbuk National University Hospital (CNUH), and Soonchunhyang University Hospital (SCHU) were transmitted to the HUPAIC.
