Efficacy and Safety of Endoscopic Third Ventriculostomy Versus Ventriculoperitoneal Shunting for the Treatment of Hydrocephalus: A Meta-Analysis

Abstract

<i>Introduction</i>: Hydrocephalus, characterized by abnormal cerebrospinal fluid (CSF) accumulation, presents significant challenges requiring timely intervention to prevent neurological complications. Endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunting (VPS) are primary surgical options, yet their relative efficacy and safety remain debated. This meta-analysis aims to compare ETV and VPS for hydrocephalus treatment, providing evidence-based insights to guide clinical decision-making. <i>Objectives</i>: To compare the efficacy of ETV and VPS in achieving symptom relief and radiological resolution of hydrocephalus. To evaluate the safety profiles of ETV and VPS by assessing perioperative and postoperative complication rates. To examine long-term outcomes following ETV or VPS placement. To conduct subgroup analyses based on patient characteristics influencing treatment effectiveness and safety. <i>Methods</i>: A comprehensive literature search was conducted in PubMed and Scopus databases to identify relevant studies comparing ETV and VPS for hydrocephalus treatment. Inclusion criteria encompassed comparative studies reporting efficacy and safety outcomes in pediatric and adult populations. Data extraction and quality assessment were performed using standardized protocols. Meta-analysis was conducted using appropriate statistical methods, with sensitivity and subgroup analyses conducted to assess robustness and variability. <i>Results</i>: Symptom improvement was comparable between ETV and VPS, with lower major complications associated with ETV. Mortality and postoperative complications favored ETV, although VPS exhibited lower CSF leakage risk. Overall success rates were similar, but ETV demonstrated superior safety profiles. Subgroup analyses revealed variations based on patient characteristics. <i>Conclusion</i>: ETV and VPS are effective in achieving symptomatic relief and radiological resolution of hydrocephalus, with ETV demonstrating superior safety profiles. Shared decision-making considering patient factors is crucial in selecting the most appropriate treatment approach. Further research is warranted to refine treatment algorithms and optimize outcomes for hydrocephalus patients.
