Laser visual guidance versus two-dimensional vision in laparoscopy: a randomized trial.

ABSTRACT:

Background

During laparoscopy, the surgeon's loss of depth perception and spatial orientation is problematic. Laser visual guidance (LVG) is an innovative technology that improves depth perception to enhance the visual field. In this trial, we examined the effect of LVG on surgical novices' motor skills, quality of task performance, and cognitive workload.

Methods

We designed a randomized controlled trial following the CONSORT statement. Thirty-two surgical novices completed the Training and Assessment of Basic Laparoscopic Techniques (TABLT) test. The first attempt allowed participants to familiarize themselves with the exercises. We then randomized the participants, and they completed a test session using either LVG or conventional two-dimensional vision.
