The purpose of this study was to compare the utility of 2 surgical models for obstetric anal sphincter repair for improving resident knowledge, confidence level, and repair technique.
Third- and fourth-year obstetrics and gynecology residents at LAC + USC Medical Center performed simulated anal sphincter repair on both sponge and beef tongue surgical models. Resident knowledge, confidence, technical skill, and preference were assessed after each model was performed.
Both models significantly improved resident confidence (sponge, P = 0.017; tongue, P = 0.016) and knowledge (60% correct before intervention vs. 92% correct after intervention, P < 0.001). There was no difference detected between the 2 models. All participants preferred the tongue model to the sponge model. When performing both models, performing the tongue model after the sponge model resulted in a further increase in confidence (P = 0.008) CONCLUSIONS: Both models are excellent tools to aid in resident teaching of obstetric anal sphincter repair and significantly increase residents' knowledge and confidence.
本研究旨在比较两种产科肛门括约肌修复手术模型在提高住院医师知识水平、信心程度和修复技术方面的效用。
洛杉矶县+南加州大学医学中心的妇产科三、四年级住院医师在海绵和牛舌手术模型上进行模拟肛门括约肌修复。在每个模型操作后，评估住院医师的知识、信心、技术技能和偏好。
两种模型均显著提高了住院医师的信心（海绵模型，P = 0.017；牛舌模型，P = 0.016）和知识水平（干预前正确率为60%，干预后为92%，P < 0.001）。两种模型之间未检测到差异。所有参与者都更喜欢牛舌模型而非海绵模型。在进行两种模型操作时，先进行海绵模型后进行牛舌模型会使信心进一步增强（P = 0.008）。结论：两种模型都是辅助住院医师进行产科肛门括约肌修复教学的优秀工具，并且能显著提高住院医师的知识水平和信心。
