Comparison of early and late decompressive craniectomy on the long-term outcome in patients with moderate and severe traumatic brain injury: a meta-analysis
Abstract
Several studies have searched whether early decompressive craniectomy (DC) can improve the long-term outcome of patients with moderate and severe traumatic brain injury (TBI). However, the effects of early DC remain unclear. The purpose of this meta-analysis was to assess whether early DC (time to surgery after injury <24 h) is better than late DC (>24 h) after moderate and severe TBI. Two reviewers independently searched Pubmed, Embase, ISI web of science, the Cochrane Library and Scopus databases from inception to 4 November 2014. Studies comparing the long-term outcome of patients following early and late DC after TBI were included. The long-term outcomes were evaluated by Glasgow Outcome Score, Extended Glasgow Outcome Score. Newcastle-Ottawa Scale was used to assess the methodological quality of included studies. Characteristics of the selected studies were extracted. Pooled results were presented by odds ratios (ORs) with 95% CIs. I(2) was used to test heterogeneity. Pearson correlation coefficient was used to detect the relationship between bilateral pupil abnormality and unfavourable outcome. Five articles were eligible for this meta-analysis. The pooled results of comparison of unfavourable outcome and mortality reveal...Continue Reading
