A simple and safe method to visualize the inferior pouch in esophageal atresia without fistula.

The authors studied the true "dynamic" distance between the esophageal stumps in type I atresia in order to perform the delayed anastomosis at the most favorable time. The position of the inferior pouch was fluoroscopically evaluated in four patients, inserting a Hegar dilator through the gastrostomy. The superior esophageal pouch was delineated by a Replogle tube. No anesthesia was required. In all cases the procedure was simple, safe, fast, and accurate. No complications occurred, and patients could be operated upon at the optimal time.
