Using the Internet to enable access to medical conferences.

OBJECTIVE: The goal of expanding access to individuals with disabilities to scientific and medical conferences is supported by both the Americans with Disabilities Act and the National Institutes of Health. DESIGN: Live-streaming video broadcast over the internet is widely available, although it has been used only in a limited fashion by the medical community. A consumer-oriented medical and rehabilitation conference concerning the rare disabling disease, fibrodysplasia ossificans progressiva, was broadcast via the world wide web. The address of a web page was announced before the conference to three computer users' groups that were considered likely to have an interest in the conference. The web page presented a live-streaming video broadcast of the conference. A phone line was installed, thereby allowing viewers to ask questions of the presenters during the question and answer periods. RESULTS: Sixteen users logged in 83 times to view the conference over a 2-day period. Five (23%) of 22 members of a fibrodysplasia ossificans progressiva internet users' group tuned in from distant places as The Netherlands and Israel. CONCLUSIONS: The internet is a viable tool to expand access to and increase the participation of individuals with disabilities in scientific and medical conferences. This technology should be used routinely in conferences of interest.

Transmission of live laparoscopic surgery over the Internet2.

BACKGROUND: Video broadcasting of surgical procedures is an important tool for education, training, and consultation. Current video conferencing systems are expensive and time-consuming and require preplanning. Real-time Internet video is known for its poor quality and relies on the equipment and the speed of the connection. The Internet2, a new high-speed (up to 2,048 Mbps), large bandwidth data network presently connects more than 100 universities and corporations. We have successfully used the Internet2 to broadcast the first real-time, high-quality audio/video program from a live laparoscopic operation to distant points. METHODS: Video output of the laparoscopic camera and audio from a wireless microphone were broadcast to distant sites using a proprietary, PC-based implementation of H.320 video conferencing over a TCP/IP network connected to the Internet2. The receiving sites participated in two-way, real-time video and audio communications and graded the quality of the signal they received. RESULTS: On August 25, 1998, a laparoscopic Nissen fundoplication was transmitted to Internet2 stations in Colorado, Pennsylvania, and to an Internet station in New York. On September 28 and 29, 1998, we broadcast laparoscopic operations throughout both days to the Internet2 Fall Conference in San Francisco, California. Most recently, on February 24, 1999, we transmitted a laparoscopic Heller myotomy to the Abilene Network Launch Event in Washington, DC. CONCLUSIONS: The Internet2 is currently able to provide the bandwidth needed for a turn-key video conferencing system with high-resolution, real-time transmission. The system could be used for a variety of teaching and educational programs for experienced surgeons, residents, and medical students.
