Abstract

Objective: Among other indispensible qualities, a competent surgeon needs to be technically skilled. With the advent of minimally invasive procedures, technical demands on surgeons also increase. Will it be possible for all individuals to meet these technical demands through motivated practice or is there a trait such as "aptitude" that determines ultimate surgical skill?, Design: Baseline laparoscopic psychomotor aptitude (on a box trainer), visual-spatial aptitude (Schlauch figures test), and interest in surgery (10-point Likert scale) were measured in our study group. Afterward, study participants attended a 3-hour hands-on laparoscopy training, followed by 2 additional weeks of voluntary practice for those who were motivated to do so. After these 2 weeks, participants were retested using the laparoscopic box trainer., Setting: All research was performed in the Center for Surgical Technologies, Leuven., Participants: A total of 68 fifth-year medical students without prior experience in laparoscopy from the University of Leuven., Results: Multiple additive regression analysis showed significant effect for psychomotor aptitude (26%), interest in surgery (9%), and voluntary practice (18%) on final box trainer performance. No correlation was found between aptitude and interest in surgery (p = 0.27). No correlation was found between aptitude and amount of voluntary practice. High-aptitude students more frequently applied for surgical disciplines in their final career choice (50% vs 18%, p = 0.01)., Conclusions: This study shows that aptitude and motivated practice equally influence final box trainer performance. Students with lower aptitude do not automatically train more. Although the interest in surgery was initially not related to psychomotor aptitude, eventually students with high aptitude apply more frequently for a surgical career., (Copyright © 2015 Association of Program Directors in Surgery.

Abstract

To prevent unnecessary mistakes and avoidable complications in laparoscopic surgery, there has to be proper training. A safe way to train surgeons for laparoscopy is simulation. This study addresses the face validity of ProMIS, an Augmented Reality laparoscopic simulator, as a tool for training suturing skills in laparoscopic surgery. A two-paged, 12-item structured questionnaire, using a five-point-Likert scale, was presented to 50 surgeons/surgical interns. The participants were allotted to two groups: an "expert" (50 procedures; N=23) and a referent group (50 procedures; N=27). Non-parametric statistics were used to determine statistical differences. General consensus existed in both expert and referent groups, delineating ProMIS as a useful tool in teaching suturing skills surgeons/surgical interns (mean + or - st dev, resp, score 4.91 + or - 0.42 and 4.93 + or - 0.38) with regard to realism, tactile feedback, and suturing techniques. Significant differences in opinion regarding the ergonomics and design of ProMIS between the expert and referent groups existed. The ProMIS Augmented Reality laparoscopic simulator is regarded as a useful tool in laparoscopic training in both expert and referent groups. Although significant differences in opinion existed with regards to ergonomics and design of ProMIS, they were present between experts and novices.

Abstract

This study determines the expert and referent face validity of LAP Mentor, the first procedural virtual-reality (VR) trainer. After a hands-on introduction to the simulator a questionnaire was administered to 49 participants (21 expert laparoscopists and 28 novices). There was a consensus on LAP Mentor being a valid training model for basic skills training and the procedural training of laparoscopic cholecystectomies. As 88% of respondents saw training on this simulator as effective and 96% experienced this training as fun it will likely be accepted in the surgical curriculum by both experts and trainees. Further validation of the system is required to determine whether its performance concurs with these favourable expectations.
