Abstract:
Objective To develop and evaluate a porcine model for training the single needle running suture method of laparoscopie urethrovesical anastomosis(LUA). Methods Twenty minipigs with mean weight of 30kg were general anaesthetized with Sumianxin solution 0. 1 ml/kg intramuscularly. Pneumoperitoneum was created by insufflation of carbon dioxide by a veress needle inserted through the umbilicus. One 10mm port and two 5mm ports were positioned after the establishment of pneumoperitoneum. The intestine was used as "bladder". The procedures were completed with the single needle running suture method of laparoscopic urethrovesical anastomosis. Six trainees performed the LUA procedure based on the models during a laparoscopic training course, following the technique used in the operation room. The learning curve was analyzed by operative time. Results The porcine model for laparoscopic training was established successfully and 3 LUAs could be performed on each pig. Each trainee performed 10 LUAs based on the models during the training course of laparoscopic urology. The operative time declined from (55.3±10. 4)min initially to (22.4±4.8)min (P＜0. 01) after the training course. At the end of training, all trainees could accomplish a watertight LUR procedure on the model. Conclusions The establishment of the training model is feasible. The trainees could acquire the skills necessary to perform LUA in vivo based on this model. The model provides a platform for training the basic techniques of LUA procedures.
