[Congenital esophageal stenosis with submucosal fibrosis: report of one case].

Esophageal stenosis due to an intrinsic congenital factor is uncommon in infancy. We report a case of a male newborn infant, who was well at birth and presented with foamy sputum from the third day of life and vomiting at 18 days of age. Esophagogram revealed a narrowed segment, about 1 cm in length, at the level of the seventh and eighth cervical vertebral bodies, with proximal dilatation. There was no sign of gastroesophageal reflux. Operative findings: There was no external compression, foreign body or fistula, but a 1 cm length of esophageal stenosis was found. The stenosed segment was hard on palpation. Segmental resection of the stenosed region, with direct anastomosis of the esophagus was performed. Pathological examination of the narrowed segment revealed fibrosis of the submucosa without any tracheobronchial remnent components.
