Abstract

Objectives: Surgical intervention is the standard treatment for communicating hydrocephalus (CH), a condition involving cerebrospinal fluid accumulation in the ventricles without a blockage. The optimal surgical approach for CH remains uncertain, with clinical decisions varying by patient characteristics and institutional practices. This study aims to compare the efficacy and safety of surgical interventions for CH. Methods: In this systematic review and network meta-analysis (NMA), we searched PubMed, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure, Wanfang, Vip, China Biomedical Literature, and the Chinese Clinical Trial Registry from inception to September 24, 2024, for randomized controlled trials. Primary outcomes were efficacy (favorable outcome) and safety (complications). Secondary outcomes included revision, infection, seizures, operation time (minutes), and duration of hospitalization (days). Bayesian NMAs synthesized the data, and the certainty of evidence was assessed using the confidence in NMA (CINeMA) framework. Surface under the cumulative ranking curve values were generated to rank the treatments. This study is registered with PROSPERO (CRD42024585931). Results: Of 4,159 citations identified by our search, 34 trials (2,528 participants) met the inclusion criteria. For efficacy, lumboperitoneal shunt (LPS) (risk ratio [RR] 1.18, 95% credible interval [CrI] 1.13–1.23; high certainty) and LPS with laparoscope (LPS+LS) (RR 1.27, 95% CrI 1.18– 1.39; high certainty) were more effective than ventriculoperitoneal shunt (VPS). Both LPS and LPS+LS outperformed endoscopic third ventriculostomy (ETV) and ETV with choroid plexus cauterization (ETV+CPC) (RR range 1.16–1.48; high to moderate certainty). For safety, LPS, LPS+LS, and ETV had fewer complications than VPS (RR range 0.20–0.40; high certainty). LPS+LS had fewer complications than LPS (RR 0.49, 95% CrI 0.29–0.79; moderate certainty).
