Delaying surgery for inguinal hernia in neonates: Is it worthwhile?

OBJECTIVE

The incidence of inguinal hernia is high in premature infants; however, surgical repair is a high-risk procedure for these patients. The timing of hernia repair is still controversial. This study aimed to determine the optimal timing for inguinal herniotomy in neonates in a general hospital.

METHODS

A prospective cohort study was conducted from March 2014 to September 2018. A total of 127 neonates and preterm infants were admitted to the paediatric surgery clinic with uncomplicated inguinal hernia. Herniotomy was performed in all neonates, and the patients were followed up for up to 8 months after surgery for perioperative and postoperative complications. The timing of surgery was based on the surgeon's decision along with the consent of the family to the surgical intervention.

RESULTS

Of 118 neonates, as many as 53 (45%) underwent early repair and 65 (55%) underwent late repair of inguinal hernia. The demographic data were similar between the 2 groups with no significant difference. There were no significant differences in the incidence of inguinal hernia incarceration and hydrocele formation (p = 0.11 and p = 0.8, respectively); however, there was a higher incidence of inguinal hernia recurrence (p = 0.05) and postoperative apnoea (p = 0.02) in the early repair group.

CONCLUSION

Surgical repair of inguinal hernia is feasible with low morbidity in preterm babies. The risk of hernia incarceration and testicular atrophy did not increase with delayed elective hernia repair in neonates. Delayed hernia repair decreased the risk of perioperative and postoperative complications. This study recommends delaying elective hernia repair in neonates and preterm babies.
