Oesophageal atresia: a simplified approach to early management.

Abstract

Management following the repair of oesophageal atresia (OA) with tracheooesophageal fistula (TOF) in the past included the routine use of an intercostal chest drain, a gastrostomy, or a transanastomotic tube (TAT) for enteral nutrition and a routine contrast swallow (CS) before oral feeds. There has been a trend towards simplification of the management, but this is not universal. The aim of this study was to evaluate the safety of a simplified management regime in infants undergoing primary repair of OA in a retrospective case note review of infants undergoing surgery for OA with TOF under the care of one consultant over a 12-year period. Intercostal chest drains, TATs, and CSs were not routinely used. Early enteral feeding was initiated and oral feeding was allowed in babies of adequate birth weight (BW) and gestation. A CS was only performed when there were specific anastomotic concerns. Parameters recorded included demographic details, time to first enteral feed by tube or mouth, time to full oral feeds, and complications. Forty patients were studied; 17 were managed without (group 1) and 23 with (group 2) a TAT. Sex distribution, gestational age, and BW were comparable in the two groups. In group 1, the time to the establishment of full oral feeds was 2-8 days (average 3.9). Four infants developed strictures; 2 were managed with dilatation alone and 2 required surgery. In group 2, the time to the establishment of full enteral feeds was 2-12 days (average 5.9). Four patients developed strictures; 2 underwent an anti-reflux procedure and a 3rd resection of a cartilaginous remnant. There was 1 death in a patient with intractable cardiac failure. The majority of infants with OA and TOF can thus be safely managed without routine chest drainage or CS. A sizeable minority do not require a TAT. Early introduction of oral feeds in the non-TAT group is not associated with an increased complication rate.
