Gastroesophageal reflux disease (GERD) is a well-recognized condition in neonatal period. It is common in preterm infants, clinical spectrum is wide and the management may be difficult. Nissen fundoplication operation is well established as effective treatment for GERD in most children intractable to medical therapy, but its role in neonates is less clear and its effect in premature infants is not well established. Here, we report a case of a premature infant, who had severe respiratory system problems that needed mechanical ventilation despite all medical therapy, and demonstrate dramatical clinical and radiological improvement as a result of Nissen fundoplication surgery.
