Repair of long gap esophageal atresia without anastomosis

Repair of long gap esophageal atresia represents a challenge. Several different techniques may be used. We describe 5 cases of long gap esophageal atresia managed successfully with suture approximation without anastomosis.

Retrospective review identified 5 newborns (4 males; 1 female) with long gap esophageal atresia treated with suture approximation and subsequent endoscopic and fluoroscopic placement of string for guided dilatations. Three babies had esophageal atresia without fistula, and 2 had the common type with proximal atresia and distal tracheoesophageal fistula. The babies with pure esophageal atresia had delayed repair, and those with the common type had repair 2 days after birth. All had a gastrostomy for feedings.

All 5 babies recovered uneventfully. Three babies had spontaneous fistulization that allowed easy placement of guide wire and string. Two other babies required endoscopic and fluoroscopic combined fistula creation bypassing a long needle from the upper pouch to the lower one. Initially, all had string-guided dilatations that were subsequently converted to balloon dilatations. All babies had a functioning esophagus and did not need any further surgical intervention. An average of 8 postoperative dilatations were needed.

The baby's own functional esophagus is superior to any esophageal replacement. Familiarity with different techniques to preserve it is therefore important. Suture approximation without anastomosis is a safe technique that can be applied to long gap esophageal atresia. The downside of this technique is a prolonged hospital stay, multiple dilatations, prolonged fasting, and therapy to learn to eat orally.
