Abstract
Laparoscopic colorectal surgery is considered an advanced minimally invasive procedure with a long variable learning curve Developing an evaluation tool is essential to ensure that individuals reach a certain level of competence prior to performing this procedure independently To achieve standardization and wide implementation an assessment tool must be reflective of practice across many institutionsThe purpose of this study is to validate two procedurespecific evaluation tools for laparoscopic colorectal surgery that were developed using innovative consensus methodology Two procedurespecific rating scales for laparoscopic right and sigmoid colectomy were created using the Delphi method Nine novice and nine expert laparoscopic sigmoid colectomy videos were prospectively collected and nine novice and ten expert laparoscopic right colectomy videos were recorded The experts rated the videos using the procedurespecific technical skills evaluation tool for either laparoscopic right colectomy or laparoscopic sigmoid colectomyThere were statistically significant differences between the expert and novice scores on the laparoscopic right colectomy evaluation tool the median score of novices was 638 and the expert score was 731 p = 002 Similarly there was a significant difference between the median novice score on the sigmoid tool 586 compared with the median expert score 707 p = 0003 Cronbach’s alpha was 082 for the right colectomy evaluation tool and 079 for the sigmoid rating scale
