title: Use of intraoperative esophageal manometrics in surgical treatment of gastroesophageal reflux in pediatric patients.
abstract: Intraoperative lower esophageal sphincter (LES) pressures and lenghts were measured in 10 pediatric patients requiring surgery for compications of gastroesophageal reflux. LES pressure changed significantly pre- and post-Nissen fundoplication (9.8 +/- 1.51 mm Hg vs. 32.8 +/- 2.68 mm Hg, p less than 0.001). LES length also showed a significant change (1.3 +/- 0.13 cm vs. 2.8 +/- 0.26 cm, p less than 0.001). One week postoperatively LES pressures were significantly greater than preoperative values (26.4 +/- 1.74 mm Hg vs. 15.6 +/- 2.64 mm Hg, p less than 0.01). Eight of 10 patients have been evaluated 6 mo post fundoplication. None has gastroesophageal reflux by acid reflux testing or water siphon barium esophagram. None of the 10 patients has had gas bloat syndrome during the follow-up period.
