“…It was inevitable that a compression algorithm, such as H323, on the Picturetel videoconferencing system (Picturetel Corp. Danvers, MA) would be used to downsize the surgical images, but this more or less ruined the image quality [5]. Although Damore et al [3] successfully used the Internet2 broadband network, they adopted a similar compression protocol and failed to take full advantage of the high-speed bandwidth.…”

“…2 In both cases, low bandwidth proved to be very useful for telemedicine applications. Internet-2 has been shown to provide high-resolution images, 3 but Internet-2 is simply another broadband technology, which will not be broadly available in the foreseeable future in most regions of the world. By using the ordinary telephone and a dial-up account to a local or global Internet service provider (ISP), a reliable remote node network can be established easily and affordably.…”

ObjectiveTo determine whether a low-bandwidth Internet connection can provide adequate image quality to support remote realtime surgical consultation. Summary Background DataTelemedicine has been used to support care at a distance through the use of expensive equipment and broadband communication links. In the past, the operating room has been an isolated environment that has been relatively inaccessible for real-time consultation. Recent technological advances have permitted videoconferencing over low-bandwidth, inexpensive Internet connections. If these connections are shown to provide adequate video quality for surgical applications, low-bandwidth telemedicine will open the operating room environment to remote real-time surgical consultation. MethodsSurgeons performing a laparoscopic cholecystectomy in Ecuador or the Dominican Republic shared real-time laparoscopic images with a panel of surgeons at the parent university through a dial-up Internet account. The connection permitted video and audio teleconferencing to support realtime consultation as well as the transmission of real-time images and store-and-forward images for observation by the consultant panel. A total of six live consultations were analyzed. In addition, paired local and remote images were "grabbed" from the video feed during these laparoscopic cholecystectomies. Nine of these paired images were then placed into a Web-based tool designed to evaluate the effect of transmission on image quality. ResultsThe authors showed for the first time the ability to identify critical anatomic structures in laparoscopy over a low-bandwidth connection via the Internet. The consultant panel of surgeons correctly remotely identified biliary and arterial anatomy during six laparoscopic cholecystectomies. Within the Web-based questionnaire, 15 surgeons could not blindly distinguish the quality of local and remote laparoscopic images. ConclusionsLow-bandwidth, Internet-based telemedicine is inexpensive, effective, and almost ubiquitous. Use of these inexpensive, portable technologies will allow sharing of surgical procedures and decisions regardless of location. Internet telemedicine consistently supported real-time intraoperative consultation in laparoscopic surgery. The implications are broad with respect to quality improvement and diffusion of knowledge as well as for basic consultation.Telemedicine has been used to support care at a distance through the use of expensive equipment and broadband communication links.

Recent technological advances have permitted videoconferencing over low-bandwidth, inexpensive Internet connections. If these connections are shown to provide adequate video quality for surgical applications, low-bandwidth telemedicine will revolutionize surgical practice by enabling remote real-time surgical consultation.Many of the regions around the world that have the most need for advanced surgical mentoring can le...

“…The Internet has already proved to be a powerful resource for the physician, from presenting live conferences [18] and surgical procedures [8,12,14] to the real-time broadcast of patients' vital signs from a commercial aircraft [13]. Streaming technology would allow end users to view multimedia content over a network, overcoming the limiting factor of bandwidth.…”

This study showed that the Internet is a useful and powerful real-time survey tool that can help us to assess the impact of the World Wide Web and related technologies on surgical education and practice. However, the respondents in this study belong to a biased group that is already familiar with the Internet and computer technology and thus may not be representative of the surgical community as a whole.
