Abstract
Isolated tracheoesophageal fistula without esophageal atresia is a rare congenital malformation. Its etiology is obscure. Diagnosis is difficult but must be made early. To study the clinical, radiological, and evolutionary sights of this malformation. We report 4 cases of tracheoesophageal fistula, collected in the department of pediatric surgery of Monastir Hospital and in the neonatology unit of Sousse Hospital during the period between January 2001 and December 2010. The clinical picture consisted in a coughing bout and cyanosis after each feeding. Thoracic and abdominal imaging showed aspiration pneumonia, atelectasis, and gas within the colon. Gastrointestinal opacification demonstrated the fistula in 2 cases. Tracheoscopy visualized the tracheoesophageal fistula in the other 2 cases. Treatment was surgical and consisted in the section-ligation of the tracheoesophageal fistula with pleural interposition in all cases. The course was simple in two cases with a 3-year and 3.5-year follow up, respectively, but the infants died in the other 2 cases. Although a rare malformation, tracheoesophageal fistula should be suggested as a diagnosis when respiratory symptoms occur during feeding starting during the neonatal period.
