Abstract

Background

Over the past two decades, the management of hydrocephalus has witnessed the addition of endoscopic third ventriculostomy with or without choroid plexus cauterization (ETV ± CPC) to the traditional methods including ventriculoperitoneal shunt insertion (VPSI). We conducted this study to assess mortality and complications with surgical implications associated with the two procedures in children with hydrocephalus.

Methods

We reviewed our operating theater registry to identify children below 17 years old who underwent hydrocephalus surgery for the first time in 2016. The patients were followed for up to 1 year from the date of the initial operation. Their vital status was confirmed by follow-up visits by a community nurse. Descriptive analyses were used to describe the characteristics of the patients and evaluate the study outcomes (i.e., mortality and complications).

Results

One hundred fifty-three patients were eligible for the study; 56% were males and 73.2% had primary ETV ± CPC. Complete 1-year follow-up data was available for 79 patients, and 73.4% of these had ETV ± CPC. One-year success (event-free) rates for ETV and VPSI were similar at 67.4% and 66.7%, respectively. ETVs in infants under 6 months performed poorly; failing in half the infants, who were subsequently converted to VPS. Shunt sepsis was very high, 21.4% (95% CI 10.3–36.8). The majority of surgical complications (81.8%) occurred within 3 months of surgery.

Conclusion

ETV ± CPC and VPSI carry a similar frequency of mortality and complications in our setting, and therefore, both should be considered as a treatment option for patients with hydrocephalus. As VP shunt is still used for managing most of the patients, there is still a need to prioritize measures to reduce shunt infections.
