Esophagoesophagopexy technique for assisted fistulization of esophageal atresia.

PURPOSE: We describe our experience using a modified suture fistula technique for addressing tension in longer gap esophageal atresia (EA). Esophagoesophagopexy (EEP) is the tacking of the proximal and distal ends of esophageal pouches without formal anastomosis. In this retrospective cohort, we review the outcomes of patients with EA after EEP.

METHODS: We reviewed the operative reports of EA cases treated at our institution from 1997 to 2016 and identified all patients described as having EEP.

RESULTS: Of 129 EA cases, five patients underwent EEP. Formal anastomosis was not done due to patient's instability, prematurity, or long gap. Median birth weight was 1.4 kg (0.6-2.2 kg), and median gestational age at birth was 29 weeks (25-34 weeks). Age at time of EEP ranged 0-5 months. Esophagoesophageal fistula was confirmed in three patients. All three had strictures requiring weekly dilations. One of these patients died. The two surviving patients underwent fundoplication.

CONCLUSION: We describe an alternative technique for esophageal anastomosis in patients for whom a standard anastomosis is not possible. EEP can lead to a functional anastomosis through fistulization and avoid the morbidity of multiple thoracotomies and lengthening procedures. Families should be educated on the potential need for dilations and antireflux procedures.
