PURPOSE: Myelomeningocele is typically a disabling condition that results in neurologic, orthopedic, and urologic morbidity. The aim of this study was to examine the trends over time in both incidence and outcomes of myelomeningocele (MMC) in British Columbia (BC).
METHODS: A retrospective chart review was performed of all children with MMC followed in the British Columbia Children's Hospital (BCCH) Spinal Cord Clinic between 1971 and 2016. The incidence of new MMC cases and the long-term outcomes of MMC were compared between two 10-year cohorts. The first cohort comprised children born with MMC between 1971 and 1981, and the second cohort comprised children born with MMC between 1996 and 2006.
RESULTS: A total of 309 children with MMC were followed in the BCCH Spinal Cord Clinic between 1971 and 2016. There were 101 and 46 children with MMC in the two-time cohorts, respectively. Between the earlier and later cohorts, there was a significant difference in the following: MMC incidence [2.5/10,000 births vs 1.1/10,000 births, respectively (p = 0.0002)], mortality [18 vs 0% (p = 0.0009)], and the proportion of cases repaired in under 48 h [56 vs 98% (p < 0.0001)]. For surviving children, the proportion of children attending special classes was significantly different between the earlier and later cohorts [16 vs 46%, respectively (p = 0.0002)], whereas all other outcome measures, including the proportion with hydrocephalus, kyphoscoliosis, Chiari II surgery, bowel and bladder continence, recreation participation, obesity, and ambulation, were not significantly different.
CONCLUSIONS: In BC, the incidence of new cases of MMC has decreased between 1971 and 2016, while the probability of survival for these patients has increased. Despite earlier and more universal post-natal repair, long-term outcomes have not improved significantly over time. Future research should focus on developing ways of reducing disability and improving quality of life for MMC patients and their families.
