Outcome of laparoscopic antireflux surgery in patients with nonerosive reflux disease.

As many as 50% of patients with gastroesophageal reflux disease (GERD) have no endoscopic evidence of esophagitis (EGD negative). Laparoscopic antireflux surgery (LARS) provides effective symptomatic and endoscopic healing in patients with erosive GERD (EGD positive). The surgical outcome of patients undergoing LARS for EGD-negative GERD has not received wide attention. The objective of this study was to compare surgical outcomes between EGD-negative and EGD-positive patients. During the period from June 1996 to September 1998, all patients undergoing LARS for persistent GERD symptoms despite medical therapy, who were EGD-negative, were invited to respond to a questionnaire regarding their clinical status before and after LARS. To perform a comparative analysis, the same questions were posed to a randomly selected equal number of EGD-positive patients who underwent surgery during the same study period. LARS was performed in 255 patients during the study period; 59 patients (23%) had EGD-negative GERD, and 148 (58%) were EGD-positive. Forty-eight patients (19%) did not meet the entry criteria and were excluded from analysis. LARS provided effective symptomatic relief in patients with EGD-negative and EGD-positive GERD. There were no significant differences in patient satisfaction or symptom improvement between the two groups (P = 0.82). The surgical outcome of EGD-negative patients is similar to the outcome for patients with erosive esophagitis. LARS is a valuable treatment option for patients with persistent GERD symptoms regardless of the endoscopic appearance of the esophageal mucosa.
