Successful primary repair of oesophageal atresia and distal tracheo-oesophageal fistula in a 525 g neonate, the smallest reported in literature

Advances in neonatal intensive care have meant improved survival of the extremely low birth weight neonate. We report the successful primary repair of a preterm neonate born with an oesophageal atresia and tracheo-oesophageal fistula with a birth weight of just 525 g, on day 1 of life, the smallest survivor so far reported in the literature, now followed up for 5 years.
