Delayed primary anastomosis for repair of long-gap esophageal atresia: technique revisited

Comprehensive review of delayed primary anastomosis technique for long-gap esophageal atresia, where the gap between esophageal segments is too wide for immediate repair. The approach leverages spontaneous esophageal growth in the first 8-12 weeks of life through gastrostomy and upper pouch suction, followed by definitive repair at approximately 3 months of age.
