Neonatal laparoscopic inguinal hernia repair: a 3-year experience.

Abstract

To retrospectively analyze the feasibility, safety and complication rate of laparoscopic inguinal herniorraphy in babies weighing 5kg or less. Thirty infants weighing 5kg or less underwent laparoscopic inguinal hernia repair during a 3-year period. Twenty-eight infants were born preterm and the mean body weight at surgery was 3,800kg. Internal inguinal ring was closed with a non-absorbable purse-string suture. Contralateral processus vaginalis was closed if patent. Feeding was started on the same day and the patient discharged the following day. Follow-up consisted of physical examination at 1week, 6 and 12months post-operatively. Of the 30 patients (27 males, 3 females), 11 had bilateral and 19 monolateral hernia (16 right, 3 left). At laparoscopy, 23 infants needed to have bilateral herniorraphies. The mean corrected gestational age at surgery was 49.1weeks. The mean operative time for repair was 30min for unilateral and 41min for bilateral hernia. There were not intra- or post-operative complications as well as conversions or recurrences. Laparoscopic inguinal hernia repair in newborns and in ex-preterm infants is a safe and effective procedure to perform and, perhaps, even less technically demanding than open herniotomy.
