Preoperative esophageal manometry does not predict postoperative dysphagia following anti-reflux surgery

Abstract

This prospective study was undertaken to determine the value of manometric studies in predicting postoperative dysphagia in patients undergoing laparoscopic Toupet fundoplication. Two hundred and twenty-nine out of 401 patients (57%) had preoperative dysphagia, and 26 patients had late postoperative dysphagia (6.5%). Eight patients who had no preoperative dysphagia developed dysphagia following surgery. There were no significant differences in esophageal motility for patients without postoperative dysphagia (n = 375) compared with those with postoperative dysphagia (n = 26). Among patients with postoperative dysphagia as a new symptom (n = 8), six had normal preoperative distal esophageal pressures, and none had esophageal hypomotility. In those with both pre- and postoperative dysphagia 15 of 18 had normal esophageal motility and hypomotility was only found in one. The positive predictive values of distal esophageal hypomotility and other measures for postoperative dysphagia are poor. In conclusion, preoperative manometry does not predict postoperative dysphagia following laparoscopic Toupet partial fundoplication. © 2005 ISDE.
