Surgery Vs. No Surgery: a Controlled Study of Outcomes Following Bariatric Surgery

Introduction:
Bariatric surgery has been shown to be an effective therapy that results in long term weight loss, resolution of co-morbidities and improved quality of life (QOL). Most of these studies lack comparison with a non-operative group. We hypothesize that after one year, patients who undergo bariatric surgery will see significant weight loss, resolution of co-morbidities and improved QOL compared with morbidly obese patients who do not undergo surgery.

Methods: We identified 166 patients (operative group) in our prospective bariatric database that had bariatric surgery (Roux-en-Y gastric bypass (RYGB) [n= 141] or adjustable gastric band (AGB) [n=25]) with at least 1 year of complete follow-up. Thirty patients who were initially evaluated for bariatric surgery at least one year prior, but never had an operation (non-operative group), were contacted for follow-up. Demographics (age, gender), weight, BMI, co-morbidities (joint pain, hypertension, diabetes, GERD, hypertriglyceridemia, obstructive sleep apnea) and QOL (Obesity Adjustment Survey) were compared initially and at 1 year follow-up. Either ANOVA, t-test or Chi-Square was used for analysis. Significance was set at p
