Objective:To investigate the clinical characteristics and treatment of congenital esophageal atresia(CEA). Methods:The records of 18 children who suffered from CEA and were treated in our hospital from 2002 to 2009 were analyzed.Surgery was refused in 5 cases and the others underwent operation. Results:Among the13 operated children who underwent one stage ligation of esophagotracheal fistula+esophagectomy and end to end anastomosis，11 were cured，4 suffered anastomotic stricture which was relieved by balloon dilation,and 2 children had anastomotic leakage，one of which was cured by conservative treatment and the other by reoperation .Two children died，one from respiratory failure 3 days after operation and the other from anastomotic leakage and heart failure at 6 days after operation. Conclusions:Early diagnosis,prevention and aggressive treatment of complications are the key facetors to improve the outcome of congenital esophageal atresia.
