BackgroundA meta-analysis was performed for a comparison of outcomes between video-assisted thoracoscopic surgery (VATS) and thoracotomy for congenital lung malformations (CLM).MethodsElectronic databases, including PubMed, Scopus, Embase, and the Cochrane Library were searched systematically for literature aimed mainly at reporting the therapeutic effects for CLM administrated by VATS and thoracotomy.ResultsA total of 40 studies meeting the inclusion criteria were included, involving 2896 subjects. VATS was associated with fewer complications [odds ratio (OR) 0.54; 95% confidence interval (CI), 0.42-0.69], less use of epidural anesthesia (OR, 0.08; 95% CI, 0.03-0.23), shorter length of hospital stay [standard mean difference (SMD) -0.98; 95% CI, -1.4 to -0.55] and chest drainage (SMD, -0.43; 95% CI, -0.7 to -0.17), as compared with thoracotomy. However, thoracotomy showed superiority in reduced operative time (SMD, 0.44; 95% CI, 0.04-0.84). Pearson analysis (Pearson r = 0.85, 95% CI, 0.28 to 0.98, p = 0.01) and linear regression (R square 0.73) confirmed a positive correlation between percentage of symptomatic cases and conversion in patients using VATS.ConclusionVATS is associated with fewer complications, less use of epidural anesthesia, shorter length of stay and length of chest drainage, but longer operative time, as compared with thoracotomy. Symptomatic patients with CLM using VATS may be prone to conversion to thoracotomy.The reviews of this paper are available via the supplemental material section.
