Resumen
Introducción

Para adquirir experiencia en una técnica quirúrgica se requiere un período de aprendizaje.

Objetivo

Estudiar la curva de aprendizaje de la técnica de Stoppa (GPRVS), para la reparación de la hernia inguinal bilateral.

Pacientes y métodos

Se incluyó a 170 pacientes (340 hernias) intervenidos entre enero de 1995 y diciembre de 2001 por hernia inguinal bilateral mediante la técnica de Stoppa. Su edad media era de 57,2 años (rango, 28-89), 7 eran mujeres y 163 varones (96%). Se practicó cirugía urgente por hernia incarcerada en 6 casos (3,5%).

Resultados

La tasa de hernias reproducidas, enfermedades concomitantes y técnicas quirúrgicas asociadas fue similar en el período. El tiempo operatorio disminuyó de 100 (1995) a 61 min (2001). Se dejó drenaje en el 100% de los casos en 1995 y sólo en el 6,6% en 2001. La anestesia regional pasó del 25 (1995) al 83% (2001), la estancia hospitalaria de 5,1 a 1,5 días (2001) y la morbilidad del 50 (1995) al 13% (2001) (p < 0,0001). La tasa media de recidivas fue del 1,7%, con dos casos en los 30 primeros (6,6%) y uno en los 140 restantes (0,7%) (seguimiento, 1-76 meses). En 1995 la técnica era iniciada y realizada por un cirujano en el 100% de los casos, mientras que en 2001 este porcentaje se redujo al 42%, incrementándose la participación del resto del servicio y de los residentes.

Conclusiones

Los primeros 25-30 casos de una técnica quirúrgica constituyen la curva de aprendizaje, con la mayor tasa de morbilidad, dificultades técnicas y operatorias y días de estancia hospitalaria. Con la experiencia mejoran los resultados, lo que afecta a todos los cirujanos que la ejecutan.

Introduction

The acquisition of a surgical technique involves a learning curve.

Objective

To study the learning curve in Stoppa’s technique (giant prosthetic reinforcement of the visceral sac [GPRVS]) for the repair of bilateral inguinal hernias.

Patients and methods

One hundred seventy patients (340 hernias), who underwent surgery using Stoppa’s technique for bilateral inguinal hernia between January 1995 and December 2001 were included. The mean age was 57.2 years (range: 28-89 years). There were seven women and 163 men (96%). Six patients (3.5%) required emergency surgery for incarcerated hernia.

Results

The rate of recurrent hernias, concomitant diseases and associated surgical techniques was similar throughout the study period. Operating time was reduced from 1 hour (1995) (2001) 40 minutes to 61 minutes. Drainage was performed in 100% in 1995, and in only 6.6% in 2001. Regional anesthesia increased from (1995) 25% to (2001) 83%, hospitalstay was reduced from 5.1 days to 1.5 days (2001) and morbidity was reduced from 50% (1995)to 13% (2001) (p < 0.0001). The mean recurrence rate was 1.7%, with two recurrences in the first 30 patients (6.6%), and one in the 140 remaining patients (0.7%) (follow-up: 1-76 months). One surgeon introduced and performed the technique in 100% of the patients in 1995, and in 42% in 2001, as participation of other members of the department and residents increased.

Conclusions

The first 25-30 operations using a surgical technique constitute the learning curve with increased morbidity, technical difficulties, operating time and days of hospital stay. In all surgeons performing the technique, experience improves the results.
