Tracheal left mainstem bronchus and obstructive gastric mucosal intussusception associated with esophageal atresia.
A tracheal left mainstem bronchus and gastric outlet obstruction owing to gastric mucosal intussusception occurred in a child who had esophageal atresia and tracheoesophageal fistula. Bronchography and bronchoscopy, indicated because of persisting atelectasis and ventilation dependency, showed a tracheal left mainstem bronchus. The atelectasis disappeared after reimplantation of the left mainstem bronchus into the carina. Feeding problems and recurrent pulmonary infections complicated the postoperative course. Radiographic imaging and esophagogastroscopy showed severe reflux esophagitis and a prepyloric mass that consisted of a gastric mucosal intussusception. Subsequent gastrotomy and resection of the intussuscepted mucosal fold relieved the gastric outlet obstruction. An antireflux procedure was performed simultaneously. The child recovered satisfactorily. It is suggested that gastric mucosal intussusception may be associated with esophageal atresia rather than with the presence of a gastrostomy tube, as has been proposed in the literature.
