Long gap esophageal atresia: lengthening technique and primary anastomosis

ObjectiveThe treatment of long gap esophageal atresia remains a major surgical challenge. The authors describe a modification of a lengthening technique based on tissue expansion to avoid sutures cutting through the esophagus.MethodsBetween January 2004 and August 2006, 4 patients did not respond to stretching, and underwent this modified esophageal lengthening technique using silastic tubes.Results and Follow-upAll infants recovered and have an intact esophagus. All infants developed gastroesophageal reflux. Thal antireflux procedure was performed in the first infant. The other 3 patients were managed conservatively. Follow-up ranged between 6 and 34 months.ConclusionsThe tissue expansion principle can be successfully applied in the esophagus through external traction. Silastic tube fixation at esophageal ends may help to apply even traction and avoid sutures cutting through the esophageal tissue.
