Validation of a Curriculum (STAC) for Technical Skill Acquisition in Minimally Invasive Surgery
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.

|Official Title:||Validation of a Structured Training and Assessment Curriculum (STAC) for Technical Skill Acquisition in Minimally Invasive Surgery. A Randomized Controlled Study|
- Technical skills [ Time Frame: 6 months ] [ Designated as safety issue: No ]Participants' technical skills will be assessed in the operating room as they perform a laparoscopic cholecystectomy under supervision. The procedure will be video-recorded and sent for assessment to a blinded evaluator. Technical skills will be assessed using a previously validated technical skills assessment tool (Objective Structured Assessment of Technical Skill - OSATS)
- cognitive knowledge [ Time Frame: 6 months ] [ Designated as safety issue: No ]Study participants will complete a multiple choice quiz designed to assess congitive knowledge relating to performing laparoscpoic cholecystectomy.

Other: STAC curriculum
The STAC curriculum consists of theoretical preparation, case-based learning, proficiency-based virtual reality training, laparoscopic box training, and operating room participation.
|No Intervention: Conventional Curriculum|
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.
