Teaching Pediatric Straddle Injury Repair with Use of a 3D Printed Model

      ABSTRACT

      Study Objective

      To determine the utility of a 3D vulvar model for teaching pediatric straddle injury repair.

      Design

      Prospective study.

      Setting

      Two academic hospitals.

      Participants

      Twenty obstetrics and gynecology residents

      Interventions and Main Outcome Measures

      Knowledge score on the basis of a 7-question pre/post test. Likert scale questions evaluated the 3D model as a teaching tool.

      Results

      Twenty residents participated; 2 (10%) had ever repaired a straddle injury. Knowledge scores increased after model use and didactic session from 3.05 of possible 7 to 6.35; P = .001. Only 2/20 (10%) residents “agreed” or “strongly agreed” with the statement, “I am comfortable repairing a straddle injury” before the intervention, compared with 19/20 (95%) afterward (P < .001). Of 20 residents, 19 (95%) believed that it simulated surgical experience “very well” or “well.”

      Conclusion

      The use of a 3D pediatric vulvar model can simulate surgical experience and can be an effective teaching tool when combined with a didactic session on pediatric straddle injury.
