Thoracoscopic versus conventional open repair of tracheoesophageal fistula in neonates: A short-term comparative study

Esophageal atresia with or without a tracheo-esophageal fistula is a challenging anomaly in neonates. Thoracoscopic repair is gaining popularity now in pediatric surgery community. The present study aims at comparing the short term outcomes of thoracoscopy versus classic thoracotomy for repair of such conditions.

Thirty neonates with tracheoesophageal fistula were randomly divided into two equal groups (n=15) after excluding patients with birth weight <2000g, multiple associated anomalies and cardiorespiratory instability. One group had conventional open repair while the other had thoracoscopic repair. Demographic data, intraoperative result and post-operative findings were recorded and compared between both groups.

Both groups showed similar results regarding demographic and patients' characteristics. Thoracoscopic repair had relatively longer, yet non-significant operative time but with highly significant difference in preserving azygos vein. There was low conversion rate with thoracoscopy (6.66%). Open repair resulted in a longer hospital stay (11.73±5.68 vs 9.2±2.95). Complication rate was comparable in both groups; however, thoracoscopy was associated with better cosmetic results as reported by parents and surgeons (p=0.00).

Compared to thoracotomy, thoracoscopic repair offers a less invasive, effective and safe technique with similar short term outcomes, but with superior cosmetic results and better ability to spare azygos vein.
