Evaluation of Azygos vein Preservation Necessary in Primary Repair of Trachea Esophageal Fistula in Patients with Esophageal Atresia

Abstract

Introduction: Esophageal atresia is one of the most common congenital anomalies in neonates, and it can increase the incidence of complications and mortality, so it is essential to find a way to cure this disease more successfully. Therefore, the aim of this study was to evaluate the efficacy of maintaining the azygos vein in esophageal fistula in esophageal atresia patients. Materials and Method: This study was performed on 40 neonates (20 patients in the preserved group and 20 patients in the ligation group). After recording the patient's demographic data, the complications of both surgical procedures, duration of surgery and hospital stay were recorded. Chi-square and t-tests were used to compare the data. Results: In the present study, it was found that the maintenance of azygos vein in neonates with esophageal atresia can increase the duration of surgery (P <0.05), but it also reduces the hospitalization and ICU stay and, on the other hand, the incidence of various complications such as pneumonia and anastomosis leak decreased. (P <0.05) Conclusion: Therefore, in neonates who are candidates for surgical treatment of esophageal atresia and who are admitted to the surgical department, this surgical method can be used instead of the classical
