Laparoscopic inguinal hernia repair in premature neonates: is it safe?

Abstract

Objective

With advances in clinical medicine, many premature babies nowadays can have excellent survival outcomes. As the incidence of inguinal hernias in this group is high and there is scarce data in the literature regarding the optimal timing for repair, this study aims to review our experience in laparoscopic repair in premature infants.

Methods

In our centre, premature neonates with inguinal hernia noted during hospitalization were offered laparoscopic repair when the body weights reached 2.5 kg unless there is contraindication for laparoscopy. A retrospective review was carried out for all premature neonates who underwent laparoscopic inguinal hernia repair from 2001 to 2011. The operative results, complications, incarceration risk and postoperative apnea risk were recorded.

Result

A total of 79 premature neonates received laparoscopic inguinal hernia repair during this period. The mean gestational age at birth was 31.9 weeks (27–36 weeks) and the mean gestational age at operation was 46.5 weeks (33–92 weeks). One patient had incarceration and required emergency operation while waiting for the elective repair. The mean operative time was 44.9 min (25–93 min). One patient (1.3 %) had recurrence. No postoperative apnea was noted in any patient.

Conclusion

Laparoscopic hernia repair is safe and feasible in premature neonates when they attain reasonable body size, as long as there is excellent anaesthesia support. Low risk of incarceration was noted in this study and it is worth waiting for the body weight to build up and hence facilitate laparoscopic repair.
