Gas insufflation of stomach and laparoscope intubation of distal esophagus for measurement of gap in esophageal atresia without distal fistula

Evaluation of gap length is an important part of preoperative assessment of esophageal atresia (EA) without distal tracheoesophageal fistula. A technique of measuring the esophageal gap in isolated EA using carbon dioxide gas insufflation of the stomach through a port and a laparoscope is described.
