Brief Summary

Laparoscopic bariatric surgery is an advanced laparoscopic procedure with a potential for significant morbidity and mortality along the early part of a surgeon's learning curve. Simulation-based training has been shown to improve a surgeon's technical performance and shorten the learning curves in the operating room. Despite these benefits, there is no evidence-based ex-vivo training curriculum for laparoscopic bariatric surgery. The purpose of this study is to design and validate such a curriculum. This curriculum will include cognitive training, technical laparoscopic skills training (laparoscopic gastrojejunostomy and jejunojejunostomy) and non-technical skills training in a simulated environment. The investigators will assess the effectiveness of the proposed curriculum by conducting a randomized single blinded controlled trial. Cognitive knowledge (multiple choice test), technical skills (performance of a procedure in the operating room) and non-technical skills (performance in a simulated crisis scenario in a simulated environment) will be compared between curriculum trained and conventionally trained groups. The investigators hypothesize that curriculum trained group will have superior knowledge, technical skill and non-technical skills compared to conventionally trained group.

Outcome Measures

Primary Outcomes (1)

  • Difference in operating room performance between curriculum trained and conventionally trained groups

    Surgical residents participating in the study will perform a laparoscopic jejunojejunostomy in the operating room. The procedure will be video-recorded through the laparoscopic camera. The videos will be given to a blinded and trained rater who will assess the technical proficiency of the resident using a validated rating scale.

    5 months

Secondary Outcomes (2)

  • Difference in cognitive knowledge between curriculum trained and conventionally trained groups

    5 months

  • Difference in non-technical skills between curriculum trained and conventionally trained groups

    5 months

Study Arms (2)

Curriculum training group

EXPERIMENTAL

Surgical residents in the curriculum training group will complete the entire curriculum. They will participate in a cognitive component, which will consist of self-directed readings and a faculty-led seminar. Participants will also train to proficiency in laparoscopic jejunojejunostomy and gastrojejunostomy using a laparoscopic box trainer with cadaveric porcine bowels. Finally, for the non-technical skills component participants will participate in an introductory lecture on non-technical skills in surgery, as well as a practice crisis scenario with a debriefing session.

Procedure: Laparoscopic bariatric surgery ex-vivo training curriculum

Conventional training group

NO INTERVENTION

Participants in the conventional training group will proceed through surgical residency training in the usual fashion.

Interventions

The training curriculum will consist of a cognitive, technical and non-technical components. Cognitive component will consist of self-directed readings and a faculty-led seminar. Technical component will consist of training to proficiency on cadaveric porcine laparoscopic jejunojejunostomy and gastrojejunostomy models. Non-technical component will consist of an introductory lecture on non-technical skills in surgery and a simulated crisis scenario with a debriefing session.
