We evaluated the influence of laparoscopic Nissen fundoplication on impaired esophageal motility. Methods: In this pathological manometric study, we divided the patients into two groups preoperatively: the hypomotility group (mean amplitude of esophageal contraction wave <40 mm Hg; HYPO group, n = 11) and the normal group (mean amplitude of esophageal contraction wave >40 mm Hg; NORM group, n = 43). The amplitudes of esophageal contraction waves 3 and 8 cm above the lower esophageal sphincter and the percentage of peristaltic contraction waves of the tubular esophagus were analyzed pre- and postoperatively. Results: In total, 54 patients with GERD underwent esophageal manometry before and 6 months after Nissen fundoplication. The length and pressure of the lower esophageal sphincter were increased in both groups postoperatively (p < 0.01). Patients in the HYPO group (n = 11) showed a statistically significant increase of mean amplitude of esophageal contraction (32.8 vs. 57.3 mm Hg; p < 0.01), while no change was found in the NORM group (n = 43). A total of 72% of patients with preoperative motility disorder showed normal postoperative manometry. Conclusion: Nissen fundoplication normalizes esophageal motility, especially in patients with preoperative hypomotility. Patients with impaired esophageal motility should not per se be excluded from antireflux surgery. ER -
