Pyloroplasty in association with Nissen fundoplication in children with neurologic disorders.

Previous studies have suggested that delayed gastric emptying occurs in severely mentally retarded patients with gastroesophageal reflux. Based on this data, pyloroplasty was employed in such patients. A retrospective analysis of 99 consecutive patients who underwent primary fundoplication for GER was performed. Gastric emptying, as measured by successful removal of the nasogastric tube or elevation of the gastrostomy tube, was studied. Children with neurologic disorders had no clinically significant difference in gastric emptying after fundoplication (3.31 days) when compared with neurologically normal patients (2.21 days). When added to Nissen fundoplication, pyloroplasty did not hasten the return of gastrointestinal function in the severely impaired patients (4.91 days). A prospective study employing gastric isotope bolus feedings before and after Nissen fundoplication will determine if pyloroplasty improves gastric emptying when used in conjunction with Nissen fundoplication for patients with severe neurologic disorders.
