Thoracoscopic resection of foregut duplication cyst in a neonate

Foregut duplication is more common in girls, particularly if there is bronchopulmonary involvement. The incidence of oesophageal duplication cyst is estimated to be one in 8200 live births with male prevalence. Most duplications are benign, but the presence of ectopic gastric mucosa and the potential for malignant degeneration remain a concern. A newborn female, antenatally diagnosed with right-sided thoracic mass, was diagnosed with a foregut duplication cyst of size 4.1 cm × 3.7 cm × 8 cm in the posterior mediastinum. Thoracoscopic resection was done on day of life 14. The postoperative recovery was uneventful and histopathology confirmed the diagnosis. A literature search revealed only a few cases of an early thoracoscopic intervention, and ours is the earliest reported. Thoracoscopy in the neonatal period is safe and effective.
