Electromagnetic bougienage to lengthen esophageal segments in congenital esophageal atresia.

Some cases of esophageal atresia, either with or without tracheoesophageal fistula, are not suited for primary anastomosis. To avert the need for colon interposition in two such infants, intermittent electromagnetic force was used to pull together "bullets" placed in the esophageal ends. This method elongated and enlarged the esophageal segments enough to accomplish their anastomosis later. This approach appears feasible to use for infants whose esophageal malformation does not permit primary repair. It may also be applicable to cases of imperforate anus with a hight pouch.
