Abstract
Laparoscopic Nissen-Rossetti fundoplication is now recognized as a valid therapy for the treatment of gastroesophageal reflux disease. This retrospective study evaluates the effects of laparoscopic fundoplication on esophageal motility and correlates these effects to postsurgical symptoms. A total of 123 patients underwent laparoscopic fundoplication at our institution. Pre- and postoperative esophageal manometric data were analyzed with regard to the effect of surgery and postsurgical outcome. Postoperative lower esophageal sphincter pressure was significantly increased compared wtih preoperative values (1.7 +/- 0.8 kPa vs 0.9 +/- 0.7 kPa). Duration and amplitude of esophageal body contractions were not modified. The percentage of deglutition-induced complete peristaltic waves and the velocity of propagation were significantly decreased after surgery (P < 0.05). Postoperative symptoms were significantly correlated with postoperative lower esophageal sphincter pressure only. Laparoscopic fundoplication significantly increases lower esophageal sphincter pressure. It significantly decreases esophageal body peristaltic efficiency, a decrease that is most likely of minor clinical significance.
