Background |
Teleteaching of endoscopy has been limited by the exorbitant cost and time inherent in high-quality digital endoscopy video transmission. The Digital Video Transport System (DVTS) transmitted over advanced networks, such as Internet2 and the Asia-Pacific Advanced Network (APAN), provides a unique infrastructure for sharing uncompressed digital videos of endoscopy. This may allow high-quality, real-time, international training of diagnostic and therapeutic endoscopy techniques at a low cost.
Objective |
To test the proof of concept of long-distance teaching through live, interactive, high-resolution video transmission by using advanced networks and the DVTS. We used teleteaching of image-enhanced endoscopy techniques as a model.
Design |
Prospective multicenter pilot study.
Setting and Participants |
Trainees, faculty, and staff at 3 international endoscopy units.
Intervention |
An image-enhanced endoscopy video lecture with advanced-network technologies.
Main Outcome Measurements |
We compared image-based prelecture and postlecture test scores and secondarily assessed technical feasibility and quality.
Results |
The DVTS transmitted over advanced networks successfully transmitted uncompressed, high-resolution, digital lectures with endoscopic video (digital video format 720 × 480 pixels). Postsession scores improved. Participants highly rated the technical and informational quality. The majority reported a definite interest in participating in future sessions, with a mean rating (out of 5 [scale 1-5]) of 4.7 ± 0.5.
Limitations |
Pilot study with a limited number of participants and sessions.
Conclusion |
The DVTS transmitted over advanced networks such as Internet2 and APAN can provide the infrastructure for transmission of high-resolution, uncompressed video endoscopy for the purpose of teleteaching endoscopy.
