Esophageal motor abnormalities in gastroesophageal reflux and the effects of fundoplication.
Recordings of esophageal manometry obtained from 18 healthy control subjects and 32 patients with gastroesophageal reflux disease both before and after fundoplication were assessed. Preoperatively, the patients had a mean lower esophageal sphincter pressure at rest that was significantly lower (p less than 0.001) than that observed in the control group. The amplitude of peristaltic contractions, elicited by wet swallows, varied along the length of the esophagus. In patients with gastroesophageal reflux disease, the mean amplitudes recorded from the upper, middle, and lower esophagus were significantly lower (p less than 0.001) than those recorded from control subjects. No significant differences were observed between those patients with (53%) and without preoperative endoscopic evidence of esophagitis. After antireflux surgery (modified Nissen fundoplication), the mean amplitude of peristaltic contractions increased significantly (p less than 0.001) at all levels of the esophagus and were not significantly different from control values. This study describes motor abnormalities in the body of the esophagus associated with gastroesophageal reflux disease. These may arise secondary to gastroesophageal reflux inasmuch as they disappear after fundoplication.[1]References
