Training in laparoscopic suturing skills using a new computer-based virtual reality simulator (MIST-VR) provides results comparable to those with an established pelvic trainer system

J Laparoendosc Adv Surg Tech A. 2002 Jun;12(3):167-73. doi: 10.1089/10926420260188056.


Background: We hypothesized that the Minimally Invasive Surgery Trainer (MIST-VR; VP Medical R, London, U.K.) would be as effective as the Yale Laparoscopic Skills Course in improving laparoscopic intracorporeal suturing skills.

Materials and methods: Each student made six attempts to tie a knot laparoscopically. Students were then randomized to train on the MIST-VR for five sessions (six skills/session) or the Yale Skills for five sessions (three skills/session) over 5 days. On completion of training, all students were evaluated by a test consisting of six attempts to tie a laparoscopic knot.

Results: The percentage improvement in knot tying time did not differ significantly in the pelvic trainer group (30 +/- 21%) (from 443 +/- 135 to 311 +/- 137 seconds) and the MIST-VR group (39 +/- 21%) (from 409 +/- 109 to 256 +/- 140 seconds) (P = 0.308).

Conclusions: The MIST-VR is equivalent to the Yale Skills Course for training in the advanced laparoscopic skill of intracorporeal suturing.
