Novel Animal Model from Goat Ano Rectum and Pumpkin for Training of Surgeons in Management of Fistula in Ano

There is no perfect treatment for different types of fistulae in ano. Training in fistula management carries a long learning curve; an animal model from goat anal canal and rectum was prepared for training of surgeons in the management of benign anorectal diseases, especially fistula in ano. Simple material was used for creating this animal model. The hindgut portion of the goat was fixed in pumpkin. A hole was created in the pumpkin, and the pulp was removed to make space for the goat specimen. Anatomy was explained after dissection and fistulae were artificially created for simulation purposes. Model was used for training in a workshop conducted at our hospital, and feedback was taken from the participants on its utility, in learning anatomy of the area, primary sphincter repair, and use of endoscope and LASERs for fistula management. Model costs only rupees 500/-. Anatomy of the goat anal canal and rectum is quite similar to human beings. All the participants could appreciate the anal canal anatomy, different perianal spaces and sphincters were demonstrated, and fistulectomy and primary sphincter repair were taught. Consultant and participants appreciated the use of endoscope and LASERs in fistulous tracks in a simulated environment. All the consultants and participants strongly recommended the use of this model for future hands-on workshops. Our model was more realistic for practicing suturing in closed anal space, demonstration of perianal spaces, fistulae, and their management.
