Motor and Sensory Function of The Proximal Stomach in Reflux Disease and After Laparoscopic Nissen Fundoplication

Abstract

Post-Nissen patients have a significantly reduced postprandial gastric relaxation and significantly accelerated gastric emptying, which may explain postoperative dyspeptic symptoms. The abnormalities result from fundoplication and not from vagus nerve injury or reflux per se, because in reflux patients gastric relaxation and gastric emptying are prolonged.
