A retrospective analysis of conservative versus active management in severe open myelomeningocele
Insights
Non-surgical treatment for thoraco-lumbar myelomeningocele may be justified. Early surgery did not improve neurological outcomes at one year and potentially increased risks of hydrocephalus and ventriculitis.
Area of Science:
- Pediatric Surgery
- Neurosurgery
- Developmental Pediatrics
Background:
- Myelomeningocele is a severe congenital condition requiring surgical intervention.
- The optimal timing and necessity of surgical repair for thoraco-lumbar myelomeningocele remain debated.
- Previous studies have not definitively established the long-term benefits of early surgical intervention.
Purpose of the Study:
- To compare outcomes of surgical versus non-surgical management for thoraco-lumbar myelomeningocele.
- To evaluate the impact of early surgery on mortality, hydrocephalus, and neurological status.
- To determine if non-surgical treatment is a justifiable approach.
Main Methods:
- Retrospective comparison of 88 untreated patients (1976-1977) with 76 surgically treated patients (1964-1971).
- Analysis of baseline characteristics including sex and hydrocephalus at birth.
- Assessment of mortality, incidence of hydrocephalus and ventriculitis, and neurological status at one year.
Main Results:
- No significant differences in sex or hydrocephalus at birth between groups.
- Surgical treatment was associated with lower mortality after three months of age.
- Early surgery correlated with increased incidence of progressive hydrocephalus and ventriculitis; neurological status at one year was similar in survivors.
Conclusions:
- Non-surgical management of thoraco-lumbar myelomeningocele may be a viable option.
- Early surgical intervention did not confer neurological advantages and potentially increased complications.
- The findings suggest that a non-active approach can be justified given similar outcomes in survivors.
Abstract:
88 patients with thoraco-lumbar myelomeningocele not operated upon in the 1976-1977 period were compared with 76 patients with the same condition operated upon in the 1964-1971 period. There was no significant difference in sex and hydrocephalus at birth in the two groups. Mortality was less in the surgically treated group only after the age of three months. Ventriculitis appeared to be related to the incidence of hydrocephalus in the surgically treated group. There was a reduced risk of developing progressive hydrocephalus after birth in the untreated group, and the neurological status of the survivors at one year was the same in both groups. Interpreting the results as indicating that early surgery increased the incidence of progressive hydrocephalus and ventriculitis, and might increase survival of more disabled infants, then non-surgical treatment is justified since survivors are no worse as a result of this non-active approach.
