title: Circular myotomy of the esophagus: clinical application in esophageal atresia.
abstract: Three infants born with esophageal atresia that was repaired by end-to-end anastomosis combined with a circular myotomy on the upper segment are reported. The distance between the free surgical margins of the esophagus ranged between 1.5 and 4.5 cm. The esophageal myotomy was used to reduce the tension on the anastomosis. The suture line healed in each patient without clinical or roentgenographic evidence of breakdown. Follow-up of these patients ranged between 10 months and 3 years. Roentgenographic evaluation of their esophageal motility showed efficient peristaltic activity in the distal esophageal segment. Two of the patients had a subsequent history of impaction of solid particles in the upper esophageal segment at the age of 13 months and 2 years. The possibility that the circular myotomy contributed to this increased incidence of impaction is raised.
