A Novel Porcine Stomach Tissue Model for Laparoscopic Colpotomy Simulation.

Abstract

Hysterectomies are the most common benign gynecologic surgical procedures performed in the United States. Currently, there are no tissue models that exist to teach trainees the techniques for colpotomy during laparoscopic hysterectomy. To address this educational gap, we have created a laparoscopic colpotomy model using a porcine stomach attached to a uterine manipulator. A segment of a porcine stomach is secured onto a uterine manipulator to simulate the cervicovaginal junction. A uterus model created with craft materials and reused in subsequent sessions is placed above the porcine stomach onto the uterine manipulator tip. Porcine stomach was obtained from a local butcher or meat market costing less than $1.00 per model. The tissue can be refrigerated or frozen for storage, then thawed before each use. This model can be used with any energy device and any laparoscopic platform to teach and perform the colpotomy. Usability survey showed that trainees responded positively to the model and attendings thought it was a useful teaching tool. Trainees and faculty responded favorably to the model and stated that the use of actual tissue enhanced the realism of a colpotomy simulation. The porcine stomach laparoscopic colpotomy model is an innovative, low-cost teaching tool to add to a gynecologic surgical education simulation toolkit.
