Antireflux surgery enhances gastric emptying.

Abstract
THE PATHOGENESIS of gastroesophageal reflux disease is multifactorial.1 In surgical management, Nissen fundoplication is the favored method, with success rates of 91% to 95%.2,3 Multiple mechanisms of action have been suggested for Nissen fundoplication.4-9 Restoration of the normal lower esophageal sphincter pressure with reduced frequency of transient lower esophageal relaxation is documented,4,5 but its role in curing the esophagitis has been questioned.6,7 Esophageal motor activity was found to improve after fundoplication.8,9
