We have previously shown that routine preoperative ambulatory esophageal pH monitoring is of marginal benefit in patients with endoscopic esophagitis and heartburn. The aim of this study was to compare the results of laparoscopic antireflux surgery (LAS) in patients who had routine preoperative pH study to those who did not have a preoperative pH study. Methods: Of 340 patients who underwent LAS, 155 underwent pH study as part of a routine preoperative workup (Group 1). More recently, 185 patients without endoscopic esophagitis did not undergo pH study (Group 2). Symptoms of chest pain, heartburn, and dysphagia were scored from 0 (none) to 4 (severe) before, six weeks after and one year after surgery. One year follow up data were available for 83 and 31 patients in groups 1 and 2, respectively. Symptom scores were compared using the Mann-Whitney U test. Results: There were no differences between the two groups with respect to age. gender, and preoperative symptom scores. Both groups experienced significant improvement in reflux symptoms six weeks and one year postoperatively. There were no differences in postoperative symptom scores between the two groups.
