Abstract
Objective: To develop and validate a standing equine ovariectomy simulation model. Study design: Prospective cohort study. Methods: At the Veterinary Applied Laparoscopic Training Laboratory (VALT) in the Veterinary Teaching Hospital at Washington State University, we created a simulation model that mimics a standing equine laparoscopic ovariectomy (SELO) procedure. Face value of the model was determined by a questionnaire completed exclusively by surgeons with clinical experience in standing equine laparoscopic ovariectomy. Construct validity was determined by comparing scores obtained from two groups, an experienced surgeons group and a novice surgeons group. Metrics data, including time and precision of a number of operative components, was collected during a simulated standing equine ovariectomy procedure for the two groups. In addition, the concurrent validity was assessed by comparing the SELO model performance metrics scores to scores obtained from a highly validated basic laparoscopic skills test, the McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS) test. Result: The SELO model clearly discriminated between experienced surgeons and novice surgeons, which is evidence of the construct validity of the model. A positive correlation between the MISTELS scores and SELO model scores verified the concurrent validity of the SELO model. The face value for the SELO model was favorable. Conclusion: The face, construct and concurrent validity of the standing equine laparoscopic ovariectomy simulation model were positive which makes it a useful teaching modality for practicing the laparoscopic skills required to perform the SELO procedure.
