Abstract
Purpose: We report our preliminary experience identifying factors that contribute to differences in operative performance in laparoscopic radical prostatectomy (LRP) between trainees and experienced laparoscopic urologists based on objective and subjective feedback. Materials and Methods: Between December 2001 and May 2002, six trainees at the Institut Montsouris and Ecole Européenne de Chirurgie, Paris, were evaluated to identify the factors contributing to differences in operative performance in LRP between them and experienced laparoscopic urologists, both objectively and subjectively. Objective evaluation was done by an independent observer who was well versed in laparoscopic surgery, while all the trainees evaluated themselves subjectively. All the trainees had in vitro, in vivo, and didactic training sessions during the evaluation period. Results: The following deficiencies were noted objectively in the trainees compared with experienced laparoscopic urologists: (1) lack of perfect knowledge of each step, (2) lack of synchronized movements of the nondominant hand; and (3) easy physical fatigue. The trainees took a long time to dissect the vas deferens, seminal vesicles, and bladder neck because they did not have perfect knowledge of each step. It was difficult for them to pass the needle for ligation of dorsal venous complex because they tried to hold the needle far away from the needle tip at the wrong angle, and the direction of movement was not correct. For the urethrovesical anastomosis, they struggled to find the right angle to pass the needle on the urethral side. Conclusion: Lack of synchronized movement of the nondominant hand, easy physical fatigue, and lack of perfect knowledge of operative steps are crucial limitations for live operative performance of trainees in LRP. Incorporation of intensive well-planned in vitro training into the curriculum to correct these deficiencies and feedback from the operative performance can make a significant contribute to shortening the learning curve.
