Abstract
Objective

With the coming of the laparoscopy, multiple surgical techniques have been developed that have revolutionized the urological practice. Laparoscopic pyeloplasty has been one of the most developed techniques. However, there are very few training models that permit the surgeon to decrease the learning curve. An animal model of training for the laparoscopic pyeloplasty technique is described.

Methods

Eight procedures of laparoscopic pyeloplasty were performed using the animal model (Gallus gallus) in the laparoscopic practice laboratory of the Urology Service of the University Hospital of Caracas. The preparation times of the model and the operation times of each surgeon were compared. The statistical analysis was made calculating the mean operation time, standard deviation, frequencies and percentages. A significant value was considered as p<0.05.

Results

The laparoscopic pyeloplasty procedure was performed successfully in all of the cases by two surgeons. The preparation time ranged from a maximum of 14min to a minimum of 6min, this being the same for both surgeons in the fourth case. The operation time ranged from a maximum of 65min to a minimum of 43min, observing significant differences when comparing the times individually for each surgeon. Only one case had filtration when comparing the patency of the specimen.

Conclusions

The animal model of training of laparoscopic pyeloplasty that is described is economical, reproducible, of easy availability and it makes it possible to develop laparoscopic surgical skills and competency necessary for reconstructive surgery and techniques that warrant intracorporeal suture.

Resumen
Objetivos

Con el advenimiento de la laparoscopia se han desarrollado múltiples técnicas quirúrgicas que han revolucionado la práctica urológica. La pieloplastia laparoscópica ha sido una de las técnicas de mayor desarrollo; sin embargo, existen muy pocos modelos de entrenamiento que permitan al cirujano disminuir su curva de aprendizaje. Se describe un modelo animal de entrenamiento para la técnica de pieloplastia laparoscópica.

Métodos

Se realizaron 8 procedimientos de pieloplastia laparoscópica utilizando el modelo animal (Gallus gallus) en el laboratorio de prácticas laparoscópicas del Servicio de Urología del Hospital Universitario de Caracas. Se comparó los tiempos de preparacion del modelo y los tiempos operatorios de cada cirujano. Se realizó análisis estadístico calculando el tiempo operatorio medio, la desviación estándar, las frecuencias y los porcentajes. Se consideró un valor significativo p<0,05.

Resultados

El procedimiento de pieloplastia laparoscópica se realizó exitosamente en todos los casos por dos cirujanos. El tiempo de preparación osciló entre un máximo de 14 minutos y un mínimo de 6 minutos, siendo igual para ambos cirujanos en el cuarto caso. El tiempo operatorio osciló entre un máximo de 65 minutos y un mínimo de 43 minutos, observándose diferencias significativas al comparar los tiempos de forma individual de cada cirujano. Solo un caso presentó filtración al comprobar la permebilidad de la pieza.

Conclusiones

El modelo animal de entrenamiento para pieloplastia laparoscópica que se describe es económico, reproducible, de fácil disponibilidad y permite desarrollar habilidades y destrezas quirúrgicas laparoscópicas, necesarias para cirugía reconstructiva, y técnicas que ameriten sutura intracorpórea.
