Abstract Background: It has been suggested that antireflux surgery may cause an improvement in esophageal motor function (EMF) and lead to reduced postoperative dysphagia. Methods: We evaluated the changes in dysphagia symptom scores and esophageal and lower esophageal sphincter (LES) pressures in patients before (n= 381), at 6 months (n= 260), and at 24 months (n= 97) after laparoscopic fundoplication. Results: There was a significant increase in LES basal and nadir pressure following surgery in all patients and an improvement in EMF only in patients with poor preoperative esophageal motor function. A total of 76% of the patients reported no dysphagia or an improved dysphagia score 6 and 24 months after surgery. This improvement was more marked in patients with poor EMF. An improvement in EMF did not correlate with the improvement in dysphagia score reported by other patients. Patients with increased dysphagia scores 2 years after surgery had significantly higher LES basal and nadir pressures as compared to other patients. Conclusions: Laparoscopic Nissen fundoplication is associated with an overall reduction in dysphagia scores and leads to an improvement in esophageal motor function in patients with poor preoperative esophageal motility. Tightness and inadequate relaxation of the wrap during swallowing may be a determinant of long-term dysphagia.
