The personal digital assistant (PDA) as a tool for telementoring endoscopic procedures

Area of Science:

• Medical technology
• Surgical education
• Endoscopic procedures

Background:

• Current telementoring relies on wired infrastructure and complex videoconferencing systems.
• Mobile alternatives are needed to enhance the accessibility and flexibility of surgical telementoring.

Purpose of the Study:

• To compare the efficacy of handheld computers versus standard CRT monitors for displaying endoscopic video in telementoring.
• To assess the impact of display technology on surgical residents' ability to recognize anatomical landmarks.

Main Methods:

• Video images from endoscopic procedures were transmitted wirelessly to a handheld computer and via analog connection to a CRT monitor.
• Twenty-three surgical residents viewed procedures on both devices using a crossover design.
• A ten-question quiz assessed recognition of anatomical landmarks after viewing each procedure.

Main Results:

• No statistically significant difference was found in mean test scores between the handheld device (77.93%) and the CRT monitor (81.30%).
• Participants demonstrated equal ability to recognize anatomical landmarks regardless of the display device used.
• Scores were significantly higher for video tape one (84.35%) compared to video tape two (74.35%).

Conclusions:

• Handheld computers are a viable option for displaying endoscopic video in telementoring systems.
• Mobile devices can be effectively integrated into surgical training for telementoring residents.
• Further research is warranted to explore handheld devices in telementoring and robotic surgery systems.
