The authors have used the technique of combined retrograde flexible endoscopy and fluoroscopy on two newborn babies with esophageal atresia (EA) without tracheoesophageal fistula (TEF). This technique accurately determined the gap between the two esophageal ends and predicted the feasibility and timing of delayed primary anastomosis. Esophagostomy was not performed, and continuous Replogle tube suction of the upper pouch was maintained during the period of waiting for 10 and 14 weeks, respectively. Gastrostomy feeding allowed satisfactory growth and development during the period of waiting for esophageal growth.
