【 摘 要 】

BackgroundThe purpose of this study is to assess the impact of prior laparoscopic experience on the ability to learn laparoendoscopic single site surgery (LESS) skills.MethodsA total of 33 urologists who completed a training program in LESS surgery were recruited for this study. After completing the educational course and training, the study participants demonstrated LESS suturing and knot-tying via a 2-cm cystotomy in a live porcine model for 15 min. An objective structured assessment of technical skills (OSATS) was used to evaluate videos of each participant’s procedure. The participants were divided according to laparoscopic experience; advanced experienced group (AS), intermediate experienced group (IS), novice group (NS).ResultsThree participants in the NS group completed the porcine cystorrhaphy in 15 min (30.0%), 3 (25.0%) completed the task in the IS group, and 3 (27.2%) completed it in the AS group. There were no statistically significant differences in the mean total OSATS quality score (NS; 16.7, IS; 18.5, AS; 16.8) among the 3 groups. Concerning all each assessment, there were also no statistically significant difference. Additionaly, the mean total OSATS quantity score (NS; 4.1, IS; 3.5, AS; 4.3) did not differ significantly among groups. The NS group succeeded a mean of 1.4 knots, the IS group succeeded 0.9, and the AS group 1.3 (p = 0.727).ConclusionsThere was no significant difference among the groups in LESS proficiency after training. Surgeons who were novices in conventional laparoscopic surgery reached comparable scores to those of experienced laparoscopic surgeons after training.
