Endocrine evaluation after endoscopic third ventriculostomy (ETV) in children

Area of Science:

• Pediatric Endocrinology
• Neurosurgery
• Hydrocephalus Management

Background:

• Endoscopic third ventriculostomy (ETV) is a common treatment for obstructive hydrocephalus in children.
• The procedure involves perforating the tuber cinereum, part of the hypothalamic-pituitary neuronal network regulating endocrine function.
• Systematic data on the endocrine status post-ETV in pediatric patients are lacking.

Purpose of the Study:

• To investigate the endocrine status of children following endoscopic third ventriculostomy.
• To identify potential endocrine abnormalities associated with the ETV procedure.

Main Methods:

• Twenty children who underwent ETV were assessed.
• Evaluations included comprehensive laboratory tests (hormone levels, electrolytes, etc.), physical examinations, and anthropometric measurements (weight, height, head circumference).

Main Results:

• Elevated prolactin levels were observed in eight patients, with one showing a significant increase.
• Other endocrine parameters, such as FSH, LH, TSH, and IGF-1, were abnormal in a smaller subset of patients.
• Nine patients had weight or height outside the normal age-related centiles.

Conclusions:

• A higher-than-expected incidence of endocrine laboratory abnormalities was noted after ETV.
• Despite laboratory findings, no clinical relevance was observed in any patient.
• Further longitudinal studies are required to definitively assess the impact of ETV on endocrine regulation in pediatric patients.
