title: Comparison of 2 simulation models for teaching obstetric anal sphincter repair.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
