Comparison of ligation versus preservation of azygous vein in primary repair of esophageal atresia with tracheoesophageal fistula in neonates.

Objective: To compare frequency of anastomotic leak with ligation versus preservation azygos vein in the primary repair esophageal atresia (EA) trachea-esophageal fistula (TEF) neonates. Study Design: Randomized Controlled Trial. Setting: Department Pediatric Surgery, Pakistan Institute Medical Sciences, Islamabad. Period: October 2019 to September 2020. Material & Methods: This study involved 180 neonates (1-28 days life) both genders undergoing EA TEF and dividied azygous surgery surgery. Outcome variable was post-operative leak. Results: In a total neonates, mean age 6.75±6.39 days. Majority (n=130, 72.2%) patients were aged ≤7 There 107 (59.4%) male 73 (40.6%) female The significantly lower Azygous group (6.7% vs. 20.0%; p=0.009) as compared group. Conclusion: Preservation associated among TEF.
