“…As shown in the decade-long result, endoscopy-related teleconferences are gaining popularity 2. Recent advances in the field of diagnostic and therapeutic endoscopy “prompted” a wave of mutual learning from each other 2 6 7 8. Chung et al accurately pointed out that the conventional ways of disseminating knowledge via publication in journals and books cannot match the pace of rapid development in the field of therapeutic endoscopy and laparoscopic surgery 9.…”

Background and study aims An Endoscopic Club E-conference (ECE) was set up in May 2014 to cater to increased demand for gastrointestinal endoscopy-related teleconferences in the Asia-Pacific region which were traditionally organized by the medical working group (MWG) of Asia-Pacific Advanced Network. This study describes how the ECE meeting was run, examines the group dynamics, outlines feedback and analyzes factors affecting the enthusiasm of participants. It is hoped that the findings here can serve as guidance for future development of other teleconference groups. Methods The preparation, running of and feedback on the ECE teleconference were evaluated and described. The country’s economic situation, time zone differences, connectivity with a research and education network (REN) and engineering cooperation of each member were recorded and analyzed with regard to their association with participant enthusiasm, which was taken as participation in at least 50 % of the meetings since joining. Associations were calculated using 2-way table with chi-square test to generate odds ratio and P value. Results To date, ECE members have increased from 7 to 29 (increment of 314 %). Feedback received indicated a high level of satisfaction with program content, audiovisual transmission and ease of technical preparation. Upper gastrointestinal luminal endoscopy-related topics were the most favored program content. Those topics were presented mainly via case studies with a focus on management challenges. Time zone differences of more than 6 hours and poor engineering cooperation were independently associated with inactive participation (P values of 0.04 and 0.001 respectively). Conclusions Good program content and high-quality audiovisual transmission are keys to the success of an endoscopic medical teleconference. In our analysis, poor engineering cooperation and discordant time zones contributed to inactive participation while connectivity with REN and a country’s economic situation were not significantly associated with participant enthusiasm.

“…DVTS and H.323 are the main technologies used in recent years to secure network-based connections 1 2 12 13. In the era of DVTS a decade ago, REN connectivity was an important prerequisite for a medical teleconference 1 6 7 12. Without the large bandwidth provided by REN, it was impossible to achieve a connection via DVTS.…”

“…This study by Lee et al1 is significant as one of few original articles on teleconferencing, especially using DVTS 1,4,5. This study enlightens gastrointestinal endoscopists on technologic advances in teleconferences and stimulates the interests in and need for the establishment of such system.…”

Uncompressed high-definition (HD) video image quality is superior to compressed HD video provided in most commercially available videoconferencing products. Uncompressed HD videoconferencing tools provide a more immersive experience because there is no reduction of image information and, in most cases, lower latency. Four open source uncompressed video applications are reviewed that have been tested at the National Library of Medicine: three transmitting uncompressed HD video and one transmitting loosely compressed standard-definition video. The technical requirements for implementing each are described, and test results in terms of image quality, latency, and application reliability are presented. Because the hardware and bandwidth requirements for uncompressed HD video are relatively high and most applications are still under development, they are generally not ready for mass deployment. Some are, however, ready for pilot testing and experimentation in clinical settings by either those who have or anticipate having bandwidth sufficient to support them or those interested in researching the effects higher-quality video may have on diagnostic and other clinical outcomes.
