Letter to the Editor Comment on : Preservation of the azygos vein versus ligation of the azygos vein during surgical repair of esophageal atresia-tracheoesophageal fistula-a systematic review and meta-analysis

We read with interest the systematic review and meta-analysis by Shahid et al [1]. comparing preservation versus ligation of the azygos vein during primary repair of esophageal atresia with tracheoesophageal fistula. The authors synthesized an important body of literature addressing a long-standing technical debate in pediatric surgery, and their effort to pool randomized and non-randomized evidence is commendable.
