Amelioration of gastroesophageal reflux symptoms following Roux-en-Y gastric bypass for clinically significant obesity.
Symptoms of gastroesophageal reflux disease (GERD) are frequent in patients with clinically significant obesity and are reported to improve after Roux-en-Y gastric bypass (RYGB). The purpose of this study is to determine timing and duration of improvement of GERD symptoms in patients undergoing RYGB. Prospectively collected data from patients who underwent RYGB from January 1998 to August 2004 were analyzed. Patients answered a standardized questionnaire pre- and postoperatively inquiring about frequency of GERD symptoms (none, one episode/ week, one episode/day, more than one episode/day) and medication use. Of 606 patients undergoing RYGB, 239 patients (39%) reported GERD symptoms preoperatively (mean age 43 +/- 1 years; body mass index 51 +/- 1 kg/m2). Of these, 89 per cent of patients reported improved at 3 months post-op and 94 per cent of patients 9 months post-op (P < 0.001). Medication usage decreased from 30 per cent to 3 per cent by 3 months and 5 per cent beyond 9 months (P < 0.001). Percentage of excess weight loss was 18 +/- 1 per cent and 75 +/- 2 per cent at 3 and 9 months, respectively. Symptoms of GERD significantly improve and use of antireflux medications is reduced after RYGB independent of weight loss. RYGB may be the treatment of choice for GERD in obese patients.
