Abstract
Background: Stereoscopic (3-D) monitors and head-mounted displays have prom ised to facilitate laparoscopic surgery by increasing positional accuracy a nd decreasing operative time, To test this hypothesis, we evaluated the per formance of subjects using these displays to perform standardized laparosco pic dexterity drills. Methods: Fifty laparoscopic novices worked within an abdominal cavity simul ator using four videoscopic display configurations: (1) standard (2-D) moni tor; (2) 3-D monitor; (3) 2-D head-mounted display; and (4) 3-D head-mounte d display. Subjects repeated 3 standardized training exercises 2 times, We measured time to complete each drill and number of errors committed. Results: Mean total times to complete all 3 drills were 455, 459, 485, and 449 sec for configurations 1-4, respectively. Mean total errors committed n umbered 11.3, 10.4, 12.3, and 10.8, respectively. Neither comparison reache d statistical significance (p < 0.05). When 3-D configurations were compare d to 2-D configurations overall, a small but statistically significant redu ction in errors was noted for 1 drill only (4.3 vs 5.0, p = 0.018). Conclusions: Three-dimensional imaging slightly reduced the number of error s committed by laparoscopic novices during one test drill; this improvement , however, was not clinically significant. Neither the 3-D monitor nor the head-mounted display decreased task performance time. Widespread adoption o f this technology awaits future improvement in display resolution and ease of use.
