Objective：To summarize our experiences of diagnosing and treating typeⅠcongenital esophageal atresia. Methods：A retro－spective review was performed on 7 patients with typeⅠcongenital esophageal atresia. There were 5 males and 2 females with a gesta－tional age of 34.85－39.30 weeks and a birth weight of 2 100 to 3 000 grams. There were 1 premature infant and 4 low-birth weight infants. Four patients were congenital heart disease and one was congenital intestine malformation. Gastrostomy was performed af－ter typeⅠcongenital esophageal atresia being confirmed；then esophageal replacement with colon was conducted after 2 weeks. Fol－low-ups were implemented for postoperative complications，feedings growth and development. Results：One week after gastrostomy，one patient gave up the surgery due to kernicterus，the other 6 patients were treated by esophageal replacement with colon. After the surgery，one patient had serious pulmonary infection and couldn’t be withdrawn from mechanical ventilation；the other five were dis－charged from hospital without anastomosis orifice fistula. Patients were followed up for 1 to 5 years without suffering from anastomosis orifice stenosis and gastroesophageal reflux. Conclusion：Eesophageal replacement with colon is an effective treatment for typeⅠcon－genital esophageal atresia as lower complications.
