Effect of adjustable gastric banding on changes in gastroesophageal reflux disease (GERD) and quality of life

AbstractObjective:Bariatric surgery is an effective treatment for the reduction of weight in obese patients (BMI ≥ 40 kg/m2 or 30 kg/m2 with ≥1 comorbidities), who are refractory to behavioral and medical therapies. This study examined the effect of the adjustable gastric band (AGB) system on changes in gastroesophageal reflux disease (GERD) and patient-reported outcomes, including measures of quality of life.Methods:Two-year interim analysis of patients (N = 171) in the 5 year, prospective APEX study who reported GERD prior to the AGB procedure. An unrecorded number of hiatal hernia repairs were conducted during the APEX study.Results:At baseline, 171 of 395 patients (43%) reported GERD requiring daily medical therapy. After 2 years, 122 patients had sufficient data to assess outcome (71%). Complete resolution of GERD was reported in 98 patients (80%), improvement in 13 (11%), no change in 9 (7%), and worsening in 2 (2%). Overall, 91% of GERD patients experienced resolution and/or improvement of GERD. Ba...
