Detailed Description
All participants will be provided with chapters from a surgical atlas outlining the steps of a laparoscopic DA repair, as well as a video of a laparoscopic DA repair prior to testing the simulator. On the day of testing, they will also be given an opportunity to practice on the DA simulator. A pretesting survey will be completed to gather demographic information, surgical experience and self-reported comfort level at performing a laparoscopic DA repair. The survey responses will be used to stratify participants into experts (pediatric surgeons with ≥3 laparoscopic DA repairs and/or ≥5 advanced pediatric MIS procedures), intermediates (pediatric surgeons with <3 thoracoscopic TEF/EA repair or laparoscopic DA repairs and/or <5 advanced Pediatric MIS procedures) and novices (general surgeons or trainees without advanced Pediatric MIS experience) for analysis of results.
Participants will then be asked to perform a laparoscopic DA repair on the simulator. Their performance will be video recorded. Recordings include only the surgery being performed in the simulator, as a result there will be no identifying information in the recordings. Time to completion will be recorded. Two independent assessors will score the participants performance using the objective structured assessment tool (OSAT) global rating scale (GRS) and a task specific checklist. The repaired DA samples will be blinded and assessed for quality of anastomosis by scoring for completeness, patency, suture density, % of square knots, and leak pressures (see appendix 3).
Upon completion of the simulator testing a post-procedure survey will be completed by participants regarding their experience and to provide feedback on simulator.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
Time Frame: 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
|
Participant operative performance based on OSAT GRS: There are 6 categories that are graded on scale of 1-5, where 5 is best performance. Categories include: respect for tissue, time&motion, instrument handling, flow of operation, knowledge of specific procedure, overall performance. A grade of 1-5 is given to each category. The task specific checklist ranks if the tasks involved in completion of procedure are 1. done correctly, 2. done incorrectly, 3. not done. There are 13 specific tasks for this procedure. |
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
Time Frame: The evaluation will be completed by participants immediately after performing the procedure.
|
An evaluation of the trainer will be given to each participant upon completion of the procedure.
The Evaluation includes a 5 point scale, where 5 is highly realistic, and 1 is unsure.
The evaluation includes specific physical attributes of the trainer, realism of the materials, realism of the experience, ability to perform the specific tasks, and overall rating of the simulator.
There is also a section for written comments
|
The evaluation will be completed by participants immediately after performing the procedure.
|
3. Utility of the simulator for teaching.
Time Frame: The evaluation will be completed by participants immediately after performing the procedure.
|
The Evaluation form includes a section on the utility of the trainer as a training tool with a 5 point Likert scale - 5 being has great value and 1 being has no value
|
The evaluation will be completed by participants immediately after performing the procedure.
|
3. Utility of the simulator for assessment of skills.
Time Frame: The evaluation will be completed by participants immediately after performing the procedure.
|
The Evaluation form includes a section on the utility of the trainer as a testing tool,with a 5 point Likert scale - 5 being has great value and 1 being has not value
|
The evaluation will be completed by participants immediately after performing the procedure.
|
3. Utility of the simulator for maintenance of skills
Time Frame: The evaluation will be completed by participants immediately after performing the procedure.
|
The Evaluation form includes a section on the utility of the trainer as a tool for maintenance of skills,with a 5 point Likert scale - 5 being has great value and 1 being has no value

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
1. Time to completion of the DA repair
Time Frame: On the day of simulator testing for each participant. We anticipate simulator testing to be completed within 6 months of the start date of the study.
|
The time to completion of the DA repair will be recorded during simulator testing.
It is defined by initial insertion of the instrument into the DA simulator to the time the participant cuts the final knot.
|
On the day of simulator testing for each participant. We anticipate simulator testing to be completed within 6 months of the start date of the study.
|
2. Anastomosis quality
Time Frame: Completed within 1 year of the start of the study
|
Two blinded independent reviewers will review videos of procedures and the corresponding anastomosis specimen.
They will rate the anastomosis quality based upon completeness (yes/no), patency (yes/no), suture density (length of incision and number of sutures - this is an evaluation of spacing of sutures.
There is no optimal number, rather it is a balance of spacing appropriately to have enough sutures not to leak, but not too many, which will result in a prolonged procedure), % square knots (higher % is better), and leak pressures (high pressure is better).
|
Completed within 1 year of the start of the study
|
3. Recommendations for improvement of the DA simulator
Time Frame: The evaluation will be completed by participants immediately after performing the procedure.
|
Free text written feedback given by study participants on written section of evaluation
|
The evaluation will be completed by participants immediately after performing the procedure.
