RESUMO
Thirteen years of experience with a laparoscopic technique mimicking, as closely as possible, the classical open technique are presented in this report. Consecutive laparoscopic herniotomies in 385 children (178 girls and 207 boys; age 0.13 to 16.8 years) with a total of 525 hernia repairs were included into a retrospective review. Overall, 95% of children were treated on a day-care basis; all operations were completed laparoscopically. Mean operation time was 32.1 minutes (26.2 for unilateral hernias and 34.5 for bilateral). In total, 10.1% of children presented with clinically bilateral hernias, whereas 29.2% of clinical unilateral hernias had a patent contralateral processus vaginalis. We discovered femoral hernias in 2.6% and direct inguinal hernias in 0.5% of the cases. In 79 cases, a concomitant of umbilical herniorraphy was performed. There were no cases of testicular malposition or atrophy. We had a 1% hernia recurrence rate. Cosmetic outcome was excellent. Laparoscopy provides the surgeon with a superior diagnostic tool, facilitating the diagnosis of any kind of inguinal hernia or controlateral patent processus vaginalis and its repair in the same session; surgery- and anesthesia-related stress is minimized. This makes it an interesting alternative to the open repair of inguinal hernias in children, providing an excellent view on the cord structures and leaving them, as well as the testis, untouched.
