The management of combined oesophageal and duodenal atresia

Duodenal atresia (DA) in babies with oesophageal atresia (OA) is associated with significant morbidity and mortality. The management protocol for this combination of anomalies is not well defined and evolving. The aim of this study was to review our experience with combined OA and DA and to note the evolving trend in management at Sydney Children’s Hospital. Over the last 30 years, 225 babies with OA have been treated at our institution. Ten babies had associated DA. A total of 19 anomalies were noted; one child had multiple lethal anomalies and received no treatment. In three babies the diagnosis of associated DA was missed initially. For the nine babies who were treated, four had a primary OA repair followed by a delayed DA repair; one had cervical oesophagostomy, gastrostomy and DA repair; and two had a simultaneous repair of OA and DA with a gastrostomy. The last two patients in this series have had a primary simultaneous repair of both anomalies without a gastrostomy. The complications noted in the nine patients treated included anastomotic strictures in five, recurrent tracheo-oesophageal fistula in one, food bolus obstruction in one, and a megaduodenum requiring tapering in one. We believe that adopting a management protocol of primary simultaneous repair of both anomalies without a gastrostomy is justified. There was no apparent increase in morbidity and mortality with such an approach.
