V-012 LAPAROENDOSCOPIC VENTRAL HERNIA SURGERY; ANIMAL MODEL AND PATIENTS

Abstract

Abstract Aim Show the possibility of training abdominal wall laparoendoscopic techniques in the animal model. Material and Methods The training consists of 3 phases; in a first phase, videos of laparoendoscopic ventral hernia surgeries are displayed. In the second phase, 3 sessions are carried out in a simulation box to practice the zenith suture with a 5 cm diameter defect. For the third phase, each surgeon has four sessions of surgery with swine models; In the first three, a retromuscular dissection procedure was performed, creating and suturing a midline defect of 15×4 cm (long and transverse diameter), placement of mesh in a retromuscular position, and closure of the posterior sheath (laparoscopic RIVES). In the 4th animal model, an extraperitoneal procedure was performed (eTEP) without closure of the posterior rectus sheath. After training, these surgical techniques have been performed on patients Results The video shows the similarity of the animal model with the patient to perform the following technical steps; opening of the posterior rectus sheath, left retrorectal space dissection, midline crossover, right retrorectal space dissection, zenith suture of the anterior rectus sheaths, retrorectal mesh positioning and posterior rectus sheath suture. Conclusion Simulation and training models of minimally invasive ventral hernia surgery are useful and necessary in the training of surgeons.
