Surgeons with variable levels of experience in pediatric minimally invasive surgery (MIS) will be recruited to test the laparoscopic DA simulator. Baseline characteristics regarding their experience level in pediatric surgery, open and laparoscopic DA repairs and MIS surgery will be obtained from all participants. Prior to testing the simulator, participants will be provided with a video and book chapter describing how to perform the procedures and will be given an opportunity to practice on the simulators. Participant performance during a DA repair will be video recorded. Their identity will be blinded. Time to completion will be recorded. Two expert assessors will score their performance using a checklist and global performance rating scale. The quality of the duodenal anastomosis will be scored. The performance of novice, intermediate and expert surgeons will be compared to determine if the DA simulator is able to distinguish between performance of surgeons at various levels of experience. In addition, post-procedure survey will be completed by participants to rate the simulators based on its realism, usability and usefulness. Recommendations for improvement to the simulator will be sought.

1. Performance on the simulator as measured by a composite score of the OSAT (Objective Structured Assessment of Technical Skill) GRS (Global Rating Scale) and task specific checklist.
Timeframe: The OSAT and task specific checklists will be completed upon review of the videos by two blinded independent reviewers after all participants have completed simulator testing. It will be completed within one year of the study start date
2. Realism of the DA simulator
Timeframe: The evaluation will be completed by participants immediately after performing the procedure.
3. Utility of the simulator for teaching.
Timeframe: The evaluation will be completed by participants immediately after performing the procedure.
3. Utility of the simulator for assessment of skills.
Timeframe: The evaluation will be completed by participants immediately after performing the procedure.
3. Utility of the simulator for maintenance of skills
Timeframe: The evaluation will be completed by participants immediately after performing the procedure.
