title: Circular esophageal myotomy simulating a pulmonary or mediastinal pseudocyst.
abstract: Circular esophageal myotomy of the upper pouch in infants with esophageal atresia is an effective means of reducing anastomotic tension. This report describes two patients who developed marked postoperative dilatation of the proximal esophagus at the myotomy site. On radiographs, the dilated, air-filled esophagus simulated a pneumomediastinum or intrathoracic cyst-like structure.
