The suture fistula technique in the repair of selected cases ofesophageal atresia

Correction of esophageal atresia with tracheoesophagealfistula can present a difficult problem when distance and tension between upper and lower esophageal segments are too great for primary anastomosis. Alternatives have included staged procedures with upper pouch elongation or interpositions. In 1974, Shafer and David described an operation in which the lower segment was divided, closed, and then merely apposed to the unopened upper pouch. A central "necrosing suture" was placed through the lumina of both segments. Spontaneous fistulization between the two segments occurred postoperatively, and the resultant channel was then progressively dilated with woven silk bougies. This technique has been employed at Babies Hospital in five children. The results were excellent in four. One child failed to fistulize, and following a complicated postoperative course, died at home from accidental dislodgement of his tracheostomy tube. All five children required antireflux procedures but ultimately did well with regard to esophageal function.
