Controlled Trial to Compare Therapeutic Efficacy of Endoscopic Third Ventriculostomy Plus Choroid Plexus Cauterization with Ventriculoperitoneal Shunt in Infants with Obstructive Hydrocephalus.

CONTEXT: Ventriculoperitoneal (VP) shunt and endoscopic third ventriculostomy (ETV) are the established surgical treatments for obstructive hydrocephalus (HCP). Powerful evidence regarding the best therapeutic approach for infants with obstructive HCP is lacked.

AIMS: Comparison of the therapeutic efficacy of VP shunt and ETV/choroid plexus cauterization (CPC) in infants with obstructive HCP.

SETTINGS AND

DESIGN

This was a randomized, active control, unblind, single-center, clinical trial.

METHODS

Infants with obstructive HCP were randomly allocated to each intervention group (ETV/CPC or VP shunt). They were monitored for at least 6 months for any sign of raised intracranial pressure (rICP). The recurrence of rICP signs requiring surgical intervention was considered as intervention failure.

STATISTICAL ANALYSIS: The association between intervention group and outcome was tested with Chi-square test, and P = 0.05 or less was considered statistically significant.

RESULTS

Of the total fifty patients entering the study, 49 were included in the final analysis, 27 of them were in VP shunt and 22 in ETV/CPC group. Seventeen patients (34%) were female and 33 (66%) were male with mean age of 3.74 ± 3.1 months (range = 10 days - 11 months). Thirty-nine (79.6%) were under 6 months of age and the remaining were 6 months or older. The overall success rate in 36-month follow-up was 88.5% and 68.2% for VP shunt and ETV/CPC, respectively, with the difference being not statistically significant.

CONCLUSION

The current study determined no inferiority of ETV/CPC compared to VP shunt, and therefore, it may become an efficient treatment for obstructive HCP in infants.
