Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study describes the development and validation of a structured training and assessment curriculum (STAC) for a basic laparoscopic procedure. The investigators hypothesized that residents trained using the STAC curriculum would demonstrate superior technical skills in the operating room compared to residents that were trained using a traditional curriculum.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study was to develop and validate an ex-vivo comprehensive curriculum for a basic laparoscopic procedure. Although simulators have been well validated as tools to teach technical skills, their integration into comprehensive curricula is lacking. Moreover, neither the effect of ex-vivo training on learning curves in the operating room (OR), nor the effect on non-technical proficiency has been investigated. This randomized single-blinded prospective trial allocated 20 surgical trainees to a structured-curriculum (STAC) group or conventional residency training. The STAC curriculum consisted of: case-based learning, proficiency-based virtual reality training, laparoscopic box training, and OR participation. After completion of the intervention, all participants performed 5 sequential laparoscopic cholecystectomies in the OR. The primary outcome measure was the difference in technical performance between the 2 groups during the first laparoscopic cholecystectomy. Secondary outcome measures included differences with respect to: learning curves in the OR, technical proficiency of each sequential laparoscopic cholecystectomy, and non-technical skills.
