Endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in non-communicating hydrocephalus (NCH): comparison of outcome profiles in Nigerian children

Endoscopic third ventriculostomy (ETV) and ventriculo-peritoneal shunt (VPS) although recognized surgical options for non-communicating hydrocephalus have debatable applications.
We analysed a prospective cohort of age-matched children with non-tumor, non-communicating hydrocephalus treated with the two surgical modalities using clinically measurable parameters.
A single institution analysis of age-matched patients with non-communicating hydrocephalus treated with VPS or ETV over a 3-year period. Occipitofrontal circumference (OFC), milestone, shunt independence as well as complication profiles of patients were recorded and analysed. Mean follow-up period was 1.27 ± 0.19 years 95%CI). Data analysis were performed using SPSS version 15, Chicago, IL. Statistical tests were set at 95% significance level.
Fifty-five patients were enrolled, 25 patients had ETV, while 30 had VPS. Mean age was 2.3 ± 0.7 years (95% CI) with a range of 3 months to 4.5 years. Aqueductal stenosis was the most common indication. OFC profile decline was significant among the VPS group when compared with ETV group at 3 months follow-up (χ2 = 7.59, df = 1, p < 0.05). There was no difference among the two treatment groups χ2 = 2.47, df = 1, p > 0.05) in milestone profile. Thirteen percent of VPS, compared to (4%) ETV patients, had sepsis (χ2 = 4.59, df = 1 p < 0.05). Ninety-two percent of ETV patients remained shunt free, while 80% of shunted patients achieved ETV independence. Two patients died among the VPS group compared to one patient in the ETV group.
VPS compared to ETV is associated with an earlier milestone and OFC response. ETV is associated with lower rates of sepsis and mortality.
