Primary repair of long-gap esophageal atresia by mobilization of the distal esophagus.

Long-gap esophageal atresia remains a difficult problem for the pediatric surgeon. Several strategies for lengthening of the proximal esophageal segment have been used with relative success. Autogenous tissue conduits have resulted in less than optimal long-term results. Five patients since 1991 with long gap esophageal atresia (2 with distal tracheo-esophageal fistula [Type C], and 3 with isolated esophageal atresia [Type A]) underwent mobilization of the distal esophagus to the level of the diaphragm in order to perform a primary anastomosis. A retrospective analysis evaluated the timing of repair, when oral feeds were successfully begun, with particular attention to any ischemic sequelae related to the distal esophageal dissection. Two patients underwent immediate repair, three had delayed repair. There were no anastomotic leaks. Three patients healed without stricture. Of four patients who survived long-term, three patients are eating well and only one still requires jejunoenteric supplementation. Classic teaching dictates that dissection of the distal esophagus should not be done because of disruption of its segmental blood supply. In this series, distal esophageal mobilization was successful in facilitating a primary anastomosis. These results are encouraging as an alternative to the high morbidity and marginal long-term results of interposition grafting or gastric transposition.
