Both flexible and rigid neuroendoscopy can be used, with little empirical evidence directly comparing the two. Therefore, the authors used a propensity score\u2013matched cohort and survival analysis to assess the comparative efficacy of flexible and rigid neuroendoscopy.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Individual data were collected through retrospective review of infants younger than 2 years of age, treated at 1 of 2 hospitals: 1) Boston Children's Hospital, exclusively utilizing flexible neuroendoscopy, and 2) Nicklaus Children's Hospital-Jackson Memorial Hospital, exclusively utilizing rigid neuroendoscopy. Patient characteristics and postoperative outcomes were assessed. A propensity score model was developed to balance patient characteristics in the case mix.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A propensity score model for neuroendoscope type was developed with 5 independent variables: chronological age, sex, hydrocephalus etiology, prior CSF diversion, and prepontine scarring. Propensity score decile-adjusted and 1-to-1 nearest-neighbor matching analysis revealed that compared with flexible neuroendoscopy, rigid neuroendoscopy had an ETV\/CPC failure odds ratio (OR) of 1.43 (p = 0.31) and 1.31 (p = 0.47), respectively, compared with an unadjusted OR of 2.40 (p = 0.034). Furthermore, in a Cox regression analysis controlled by propensity score, rigid neuroendoscopy had a hazard ratio (HR) of 1.10 (p = 0.70), compared with an unadjusted HR of 1.61 (p = 0.031).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Although unadjusted analysis suggested worse ETV\/CPC outcomes for infants treated by rigid neuroendoscopy, much of the difference could be attributed to the case mix and other predictors of outcome.
