RESUMEN

OBJECTIVE: To determine the relationship between timing of initiation of temporizing neurosurgical treatment and rates of ventriculoperitoneal shunt (VPS) and neurodevelopmental impairment in premature infants with post-hemorrhagic ventricular dilatation (PHVD). STUDY DESIGN: We searched MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane Database of Systematic Reviews, and the Cochrane Center Register of Controlled Trials for studies that reported on premature infants with PHVD who underwent a temporizing neurosurgical procedure. The timing of the temporizing neurosurgical procedure, gestational age, birth weight, outcomes of conversion to VPS, moderate-to-severe neurodevelopmental impairment, infection, temporizing neurosurgical procedure revision, and death at discharge were extracted. RESULTS: Sixty-two full-length articles and 6 conference abstracts (n = 2533 patients) published through November 2020 were included. Pooled rate for conversion to VPS was 60.5% (95% CI, 54.9-65.8), moderate-severe neurodevelopmental impairment 34.8% (95% CI, 27.4-42.9), infection 8.2% (95% CI, 6.7-10.1), revision 14.6% (95% CI, 10.4-20.1), and death 12.9% (95% CI, 10.2-16.4). The average age at temporizing neurosurgical procedure was 24.2 ± 11.3 days. On meta-regression, older age at temporizing neurosurgical procedure was a predictor of conversion to VPS (P < .001) and neurodevelopmental impairment (P < .01). Later year of publication predicted increased survival (P < .01) and external ventricular drains were associated with more revisions (P = .001). Tests for heterogeneity reached significance for all outcomes and a qualitative review showed heterogeneity in the study inclusion and diagnosis criteria for PHVD and initiation of temporizing neurosurgical procedure. CONCLUSIONS: Later timing of temporizing neurosurgical procedure predicted higher rates of conversion to VPS and moderate-severe neurodevelopmental impairment. Outcomes were often reported relative to the number of patients who underwent a temporizing neurosurgical procedure and the criteria for study inclusion and the initiation of temporizing neurosurgical procedure varied across institutions. There is need for more comprehensive outcome reporting that includes all infants with PHVD regardless of treatment.

RESUMEN

OBJECTIVE: To test the feasibility of implementing a high-fidelity cleft palate simulator during a workshop in Santiago, Chile, using a novel video endoscope to assess technical performance. DESIGN: Sixteen cleft surgeons from South America participated in a 2-day cleft training workshop. All 16 participants performed a simulated repair, and 13 of them performed a second simulated repair. The repairs were recorded using a low-cost video camera and a newly designed camera mouth retractor attachment. Twenty-nine videos were assessed by 3 cleft surgeons using a previously developed cleft palate objective structured assessment of technical skill (CLOSATS with embedded overall score assessment) and global rating scale. The reliability of the ratings and technical performance in relation to minimum acceptable scores and previous experience was assessed. RESULTS: The video setup provided acceptable recording quality for the purpose of assessment. Average intraclass correlation coefficient for the CLOSATS, global, and overall performance score was 0.69, 0.75, and 0.82, respectively. None of the novice surgeons passed the CLOSATS and global score for both sessions. One participant in the intermediate group, and 2 participants in the advanced group passed the CLOSATS and global score for both sessions. There were highly experienced participants who failed to pass the CLOSATS and global score for both sessions. CONCLUSIONS: The cleft palate simulator can be practically implemented with video-recording capability to assess performance in cleft palate repair. This technology may be of assistance in assessing surgical competence in cleft palate repair.

RESUMEN

OBJECTIVE: To develop a model to predict the probability of endoscopic third ventriculostomy (ETV) success in the treatment for hydrocephalus on the basis of a child's individual characteristics. STUDY DESIGN: We analyzed 618 ETVs performed consecutively on children at 12 international institutions to identify predictors of ETV success at 6 months. A multivariable logistic regression model was developed on 70% of the dataset (training set) and validated on 30% of the dataset (validation set). RESULTS: In the training set, 305/455 ETVs (67.0%) were successful. The regression model (containing patient age, cause of hydrocephalus, and previous cerebrospinal fluid shunt) demonstrated good fit (Hosmer-Lemeshow, P = .78) and discrimination (C statistic = 0.70). In the validation set, 105/163 ETVs (64.4%) were successful and the model maintained good fit (Hosmer-Lemeshow, P = .45), discrimination (C statistic = 0.68), and calibration (calibration slope = 0.88). A simplified ETV Success Score was devised that closely approximates the predicted probability of ETV success. CONCLUSIONS: Children most likely to succeed with ETV can now be accurately identified and spared the long-term complications of CSF shunting.
