Abstract

INTRODUCTION: Training for obstetrics and gynecology residents in second-trimester dilation and evacuation (D&E) procedures is extremely limited despite the Accreditation Council for Graduate Medical Education mandating all residents to receive abortion training. Simulation-based training improves surgical competence, but no second-trimester uterine models exist. The purposes of this study were to create a realistic, low-cost model and to assess the prototype. METHODS: A uterine model was created with 6 silicone cervixes of varying texture and dilations that are interchangeable. The uterus is neoprene and opens to allow for objects to be placed within it for extraction. At a national meeting, experienced D&E surgeons assessed the prototype by using the model and then completing a questionnaire. RESULTS: Twenty-one expert surgeons completed the questionnaires. Participants rated the prototype as "useful" or "very useful" for teaching extraction skills and for training in general. Subjects agreed this represented a clinical scenario they were likely to encounter and the model allowed for practicing the necessary steps for performing D&Es. The model cost approximately $35 to fabricate. CONCLUSIONS: Expert surgeons believe that this model accurately and realistically replicates a second-trimester uterus and cervix. This prototype may be used in simulation environments to train obstetrics and gynecology residents.
