Beyond GOALS: evaluating minimally invasive surgical skills in 3-dimensional printed models with motion analysis at a Jordanian school: a randomized experimental study

This study investigated the use of motion analysis to objectively evaluate the performance of surgical interns while performing the peg transfer task in a simulator box for safe practice in real minimally invasive surgery. A fully randomized study was conducted in a multidisciplinary skills simulation lab at a medical school. Forty-one interns (i.e., novices and intermediates) and an expert surgeon participated as a reference benchmark. Videos of participants’ performance were analyzed through the proposed instrument motion analysis method and compared to the participants’ scores obtained by Global Operative Assessment of Laparoscopic Skills (GOALS). All data were statistically analyzed.
