Objectives of the study: It has been considered that “good” laparoscopists are also “good” GI endoscopists and vice versa.
However, no scientific data exist on this matter. The study was carried out to evaluate quantitatively the correlation between laparoscopic and endoscopic performance using virtual reality computer simulators, and thus to investigate whether the psychomotor skills required for the performance of these procedures are identical.
Methods and Procedures: Twenty-four surgeons and medical gastroenterologists were included in the study. All participants performed task 6 on a laparoscopy simulator (MIST-VR, Core Skills II) and level 1 of the Cyberscopy task on an endoscopy simulator (GI Mentor II). Assessment of laparoscopic manual skills was based on three parameters measured by the computer simulator - time, errors and economy of hand movement. Assessment of endoscopic skills was based on corresponding parameters - time, error score (sum of number of punctured objects and number of wall collisions), and economy score (sum of economy of movement- and confidence of manipulations
scores).
Results: Data was analysed by use of Spearman’s correlation test. Significant correlations existed between performance on MIST-VR and GI Mentor regarding all three performance parameters: time (Spearman’s r=0.669, p<0.001), error score (Spearman’s r=0.720, p<0.001) and economy of motion score (Spearman’s r=0.5, p=0.024).
Conclusion: The study provides objective and quantitative evidence of strong correlation between performance scores demonstrated during simulated laparoscopy and GI endoscopy. This indicates that psychomotor skills necessary for the performance of these procedures are identical.
