Effect of laparoscopic antireflux surgery on esophageal motility in patients with GERD

Background: Nissen-Rosetti fundoplication was developed to treat therapy resistant reflux disease. The aim of this study was to evaluate the long-term effect of laparoscopic Nissen fundoplication on esophageal motility. Methods: Esophageal manometry was done preoperatively, six month and five year after the operation at 10 patients with GERD. Peristaltic wave amplitude, propagation velocity, incidence of peristaltic dysfunction, LES length, tone and relaxation were analyzed. Results: Preoperative 6 month control 5 year control LES pressure 11,37±5,16 22,15±6,11 15,61±6,38 LES relaxation 92,9±5% 78,3±9% 76,5±4% P…
