Single surgeon case series of myelomeningocele repairs in a developing world setting: Challenges and lessons

Neural Tube Defects are the second most common group of birth malformations following congenital heart anomalies, with myelomeningoceles being the most severe manifestation (MMC). They require expedited surgical repair, preferably within 72 ​h of birth. In low- and middle-income countries (LMIC) where resources are limited, timing to MMC repair is not optimal and leads to undesirable outcomes. The purpose of this study was to determine whether a proactive approach in a setting from a LMIC could achieve repair within 72 ​h.

A concerted effort to expedite repair of all neonates referred with a MMC was undertaken from 01 January 2014 to 1 August 2015. A consensus was reached between neonatologists and neurosurgeons that neonates born or admitted with a MMC are referred immediately to surgeons and that repair will be performed within 72 ​h of birth. Hospital records of neonates who had MMC repaired during this period were reviewed for infant characteristics and hospital outcomes.

24 patients with a MMC were operated upon by the senior author (CP) during the study period. Only 13 of these patients were born at the treating institution and 11 were referred from outside hospitals. Most MMCs were in the lumbosacral region and mean MMC surface area was 19.4 ​cm². Mean time to repair for the entire series was 13.6 days. Patients born at the treating institution has a mean time to repair of 10.5 days and patients referred from outside had a mean time to repair of 17.3 days. Series wide, only 21% of neonates were operated upon in less than 72 ​h.

Despite a pro-active commitment to repairing MMCs within 72 ​h for the duration of this series, satisfactory time to repair was not achieved. Late referral, referral from outside hospitals and operating theatre availability were the predominant factors leading to delay in MMC repair. Nevertheless, time to repair in our series was significantly shorter than that reported in MMC repair series based in similar environments. This suggests that even if the gold-standard of a 72-h window cannot be achieved, neonates benefit from much quicker repair when a concerted effort to minimise repair time is employed. This study also highlights the urgent need to address health care constraints in LMIC to improve outcomes for this vulnerable group.
