Let\'s Go Tubing: A Reusable, Low-Cost Tubal Model Improves Resident Confidence with Postpartum Tubal Ligation

Purpose: To pilot an inexpensive, reusable model to aid in surgical education of postpartum tubal ligation.


Background: Postpartum Tubal Ligation (PPM BTL) is a common form of contraception, however, declining sterilization rates and surgical volume may impact a resident’s ability and confidence to perform this procedure. Our goal was to develop a reusable, low-cost model to improve resident familiarity/confidence with PPM BTL.


Methods: Our model was created using a 12-inch balloon uterus covered with press-n-seal, with attached thick yarn fallopian tubes. A 14-quart box contained the uterus and the abdominal wall was constructed using foam cushion, cloth, red felt and cling wrap for the skin/subcutaneous tissue, fascia, rectus muscles and peritoneum respectively. The model was piloted during scheduled simulation time. Residents evaluated the model’s realism and reported confidence in performing PPM BTL pre- and post-simulation.


Results: Four models were created for $21.16 each. All PGY level residents (n=12) successfully performed PPM BTLs. Most residents had little exposure to PPM BTL prior to simulation (0-5 procedures as primary surgeon). Resident confidence in performing PP BTL improved significantly post-simulation (2.58 vs. 3.42/5, p=0.005). Residents strongly agreed that the model replicated the steps of PPM BTL (4.83/5), resembled the abdominal wall (4.58/5) and peritoneal cavity (4.73/5) and was similar in difficulty to a live procedure (3.2/5). All residents strongly agreed practicing on this model could improve surgical technique (5/5).


Discussions: Our inexpensive, reusable model improved resident confidence in performing PPM BTL. Residents strongly agreed the model replicated PP BTL procedure and anatomy.
