Esophageal Atresia and Associated Duodenal Atresia: A Cohort Study and Review of the Literature

Abstract

Introduction: Esophageal atresia (EA) is associated with duodenal atresia (DA) in 3 to 6% of cases. The management of this association is controversial and literature is scarce on the topic.

Materials and methods: We aimed to (1) review the patients with EA + DA treated at our institution and (2) systematically review the English literature, including case series of three or more patients.

Results: Cohort study: Five of seventy-four patients with EA had an associated DA (6.8%). Four of five cases (80%) underwent primary repair of both atresia, one of them with gastrostomy placement (25%). One of five cases (20%) had a delayed diagnosis of DA. No mortality has occurred. Systematic Review: Six of six-hundred forty-five abstract screened were included (78 patients). Twenty-four of sixty-eight (35.3%) underwent primary correction of EA + DA, and 36/68 (52.9%) underwent staged correction. Nine of thirty-six (25%) had a missed diagnosis of DA. Thirty-six of sixty-eight underwent gastrostomy placement. Complications were observed in 14/36 patients (38.9 ± 8.2%). Overall mortality reported was 41.0 ± 30.1% (32/78 patients), in particular its incidence was 41.7 ± 27.0% after a primary treatment and 37.0 ± 44.1% following a staged approach.

Conclusion: The management of associated EA and DA remains controversial. It seems that the staged or primary correction does not affect the mortality. Surgeons should not overlook DA when correcting an EA.
