Oesophageal atresia is a group of congenital anomalies with an interruption of the continuity of the oesophagus with or without a persistent communication with the trachea.
Associated anomalies occur in 50% of cases: vertebral, anorectal, cardiac, tracheooesophageal, renal and limb defects.
The causes are largely unknown.
Infants with OA are unable to swallow saliva and are noted to have excessive salivation
The diagnosis may be suspected prenatally by a small or absent stomach bubble on antenatal ultrasound scan at around 18 weeks gestation.
Definitive management comprises surgery.
