SOTELO, Rene J. et al. Chicken gizzard: a new training model for laparoscopic urethrovesical anastomosis. Actas Urol Esp [online]. 2009, vol.33, n.10, pp.1083-1087. ISSN 0210-4806.
Objective: To create a simple, inexpensive, and reproducible model that would provide a new training option for performing urethrovesical anastomosis during laparoscopic radical prostatectomy. Material and methods: Design and experimentation were carried out in 2008. Materials employed included a laparoscopic training box, video camera, monitor, needle holder, sutures, and non-eviscerated chickens weighing more than 2 kilograms. The model was prepared with a new vision of a structure similar to the human pelvis. To create the anastomosis, we used the gizzard (bladder neck) and the rectum (urethra). Once the model was placed in the box, the anastomosis was performed in very similar anatomical conditions to those in real procedures. The anastomosis quality was assessed by means of an impermeability test and transanal endoscopy. Results: The operating field is very similar to the human pelvis. Tissues with a quality, texture, and diameter resembling those of the urethra (rectum) and the bladder neck (gizzard) offer the possibility of practicing anastomosis and anterior racket. Conclusions: The model for urethrovesical anastomosis using the chicken gizzard and rectum is simple, easy, available, inexpensive and reproducible. The anatomy of the chicken and the characteristics of its tissues allow for training under conditions very similar to those present in human cases.
