title: Gastroesophageal reflux secondary to gastrostomy tube placement.
abstract: We evaluated five children with severe psychomotor retardation who developed frequent vomiting and poor weight gain after surgical placement of a feeding gastrostomy tube. Prolonged pH probe testing before surgery did not reveal notable gastroesophageal reflux (GER). Treatment with 12-hour gastrostomy tube feeding resulted in a marked reduction in vomiting; after one year of continuous feeding, all patients had achieved significant weight gain (mean, 44.0%). Esophageal manometrics and 24-hour pH probe testing before and at the end of the 12-month continuous-feeding period demonstrated low pressures of the lower esophageal sphincter and significant GER in the five children studied. These results indicate that children may develop symptomatic GER after gastrostomy tube placement. In such patients continuous gastrostomy tube feeding may result in a cessation of vomiting and achievement of significant weight gain. Definitive antireflux surgery can then be performed with the patient in an improved nutritional state.
