Surgical Training for Bowel Endometriosis: A New Wet-lab Model

Study objective: To demonstrate a new wet-lab model for training in conservative bowel endometriosis surgery (shaving and discoid resection).

Design: Video demonstration.

Materials and methods: (1) Modeling deep infiltrating endometriosis using cryopreserved porcine rectum. (2) Conservative resection (shaving and discoid resection) using cold scissor and carbon dioxide laser (free beam and fiber). (3) Discoid resection.

Results: In this video, we present a new training model for improving the surgical management of bowel endometriosis. After dissection of the serosa and muscular layers, a modified biological glue is injected into the porcine rectum to accurately simulate an infiltrating bowel endometriosis lesion. Once dried, the simulated lesion can be resected using conventional laparoscopic instruments (cold scissors) or using more advanced techniques such as carbon dioxide laser, free beam and fiber (Storz and Lumenis). In case of bowel perforation during resection, this model enables realistic suturing.

Conclusion: This new and highly realistic model allows the next generation of endometriosis surgeons to acquire adequate training to make bowel surgery safer and more effective.
