ObjectiveA meta-analysis was performed for a comparison of outcomes between open repair (OR) and thoracoscopic repair (TR) for esophageal atresia with tracheoesophageal fistula (EA with TEF).MethodsElectronic databases, including PubMed, Cochrane Library, and Medline, were searched systematically for the literatures aimed mainly at comparing the therapeutic effects for EA with TEF administrated by OR and TR. Corresponding data sets were extracted and two reviewers independently assessed the methodological quality. Meta-analysis was performed with Stata 12.0.ResultsTen studies meeting the inclusion criteria were included, involving 447 subjects in total. It was observed that OR entailed a shorter operative time with significant statistical differences (SMD 0.604; 95% CI 0.344-0.864, P = 0). While TR was superior in two aspects: shorter length of hospital stay (SMD 0.584; 95% CI 0.214-0.953; P = 0.002) and shorter first oral feeding time (SMD 0.652; 95% CI 0.27-1.035; P = 0.001). However, meta-analyses of occurrence rate of leaks (OR, 1.747; 95% CI 0.817-3.737; P = 0.15), strictures (OR, 0.937; 95% CI 0.5-1.757; P = 0.839), pulmonary complications (OR, 1.08; 95% CI 0.21-5.44; P = 0.897), fundoplication rate of Gastroesophageal Reflux Disease (GERD) (OR, 1.642; 95% CI 0.855-3.153; P = 0.601), and blood loss (SMD 0.048; 95% CI -1.292 to 1.388; P = 0.944) showed no significant differences between OR and TR. Meta-analysis of ventilation time showed similar outcome between OR and TR (SMD 0.474; 95% CI 0.02-0.968; P = 0.06), but the result remained controversial due to estimated result changing after sensitivity analysis (SMD 0.61; 95% CI 0.16-1.07; P = 0).ConclusionsCompared with OR, a longer operative time was associated within TR group, although the TR procedure could possibly reduce the length of hospital stay and first oral feeding time. Meanwhile, the occurrence rate for leaks, strictures, pulmonary complications, and the fundoplication rate of GERD, and blood loss were similar between the OR and TR groups. Estimated result of ventilation time between the two groups remained ambiguous.
