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

BACKGROUND: Endoscopic third ventriculostomy (ETV) and ventriculo-peritoneal shunt (VPS) although recognized surgical options for non-communicating hydrocephalus have debatable applications.
OBJECTIVE: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSION: VPS compared to ETV is associated with an earlier milestone and OFC response. ETV is associated with lower rates of sepsis and mortality.
