Esophageal replacement with colon in children: functional results and long-term growth.

Twenty-three children consecutively undergoing colon interposition for esophageal replacement were evaluated with barium swallows, clinical interviews, and questionnaires. Fourteen patients underwent colon interposition because of caustic burns of the esophagus only or of the hypopharynx and esophagus. Nine children had long-segment esophageal atresia or esophageal atresia with tracheoesophageal fistula and are included in our operative group. The mean follow-up was 12.8 years for all patients. Strictures, leaks, and colon ischemia at the proximal anastomosis represent the major morbidity for the operative procedure. Analysis of growth charts reveals that patients who ingest lye tend to remain in the 50th percentile after colon transplant, while patients with esophageal atresia or tracheoesophageal fistula who had been in the 12th percentile preoperatively improved to the 33rd percentile after successful transplantation. Radiographic examinations, functional results, and growth curves demonstrated excellent results in 20 patients. Although the choice of a conduit for esophageal replacement is controversial, the surgeon can expect good long-term function and growth with the use of colon in children.
