Endoscopic surgery teleconferencing.
Modern telecommunication allowing the transmission of digitalized voice and images through telephone lines has expanded to medicine. The Integrated Digital Network System (ISDN) can be used to transmit 128 kbit/sec (ISDN-2) to 2 Mbit/sec (ISDN-30). Together with smart compression techniques a teleconferencing system can be implemented to transmit images of an endoscopic operation. In this paper 2 such experiments are described. In the first experiment a laparoscopic cholecystectomy performed in the Netherlands is followed at the same time by surgeons in Hawaii through ISDN-2 lines. In the second experiment a laparoscopic hernia repair was followed in Orlando during a congress using ISDN-6 lines. The images sent over the ISDN-2 lines are rather blurry with rapid movement. The images over the ISDN-6 lines were more acceptable. Data compression and decompression results in a time delay of approximately 1 second, which seems not disturbing during the connection. The cost of communication is comparable to telephone communication, which makes this form of telecommunication feasible in surgical practice.
