Correlation of surgical trainee performance on laparoscopic versus endoscopic simulation

Abstract

Background

Both laparoscopy and endoscopy are image-based procedures, which are less intuitive than traditional open surgery and require extensive training to reach adequate proficiency. Currently, there is lack of understanding as to how the skills in one image-based procedure translate to another, such as endoscopy to laparoscopy and vice versa. The aim of our study was to explore the relationship between endoscopic and laparoscopic skills using a Fundamentals of Laparoscopic Surgery (FLS) trainer, a traditional virtual reality endoscopic trainer and a “desk-top” endoscopic physical simulator.

Methods

Senior surgical residents from across Canada participating in an advanced laparoscopic foregut training course were enrolled in the study. Participants were assessed performing the FLS laparoscopic suturing task, the Endobubble 2 task (Simbionix, GI Mentor), and a forward viewing peg transfer on the novel Basics in Endoscopic Skills Training Box (BEST Box).

Results

There was significant correlation between the participant’s skill in simulated laparoscopic suturing and simulated endoscopic skill using the BEST box (Pearson coefficient (r) was 0.551 (p = 0.033) and the coefficient of determination (r2) was 0.304). There was a trend towards correlation between laparoscopic suturing time and Endobubble 2 score, but this did not reach statistical significance (r = 0.458, p = 0.086; r2 = 0.210).

Conclusions

Performance in the two physical simulators, laparoscopic suturing and simulated flexible endoscopy using the BEST box, showed a correlation. This study adds to the growing body of evidence that laparoscopic and endoscopic skills are complementary and has the potential to impact simulation training involving both skill sets.
