Objective:
To determine the clinical acceptability of various levels of video compression for remote proctoring of laparoscopic surgical procedures.
Design:
Observational, controlled study.
Setting:
Community-based teaching hospital.
Participants:
Physician and nurse observers.
Interventions:
Controlled surgical video scenes were subjected to various levels of data compression for digital transmission and display and shown to participant observers.
Main Outcome Measures:
Clinical acceptability of video scenes after application of video compression.
Results:
Clinically acceptable video compression was achieved with a 1.25-megabit/second data rate, with the use of odd-screen 43.3:1 Joint Photographic Expert Group compression and a small screen for remote viewing.
Conclusion:
With proper video compression, remote proctoring of laparoscopic procedures may be performed with standard 1.5-megabit/second telecommunication data lines and services.
