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

Abstract

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.
