Gastric Bypass Better than Gastric Band for Long-Term Results

Oct 17, 2014


Gastric bypass surgery shows better outcomes for long-term weight loss, controlling type 2 diabetes, hypertension, and cholesterol level….
Puzziferri and colleagues conducted a clinical review of 29 studies (7,971 patients) looking at outcomes of gastric bypass, gastric band or sleeve gastrectomy on patients with BMI ≥35 at 1 year after surgery. The researchers examined the effectiveness of each procedure for weight loss, type 2 diabetes, hypertension, and hyperlipidemia.
The results suggest that greater weight loss was accomplished with gastric bypass, 65.7%, compared to gastric band, 45%. Also, remission rate of HbA1c <6.5% without medication was higher with gastric bypass, 66.7%, compared to gastric band, 28.6%. The remission rates for hypertension were much higher with gastric bypass, 38.2%, compared to gastric band, 17.4%. Moreover, the remission rates for hyperlipidemia were also greater after gastric bypass, 60.4%, compared to gastric band, 22.7%.
“Studies of bariatric surgery long-term outcomes demonstrate substantial and sustained weight loss for gastric bypass procedures exceeding that for gastric band,” the researchers wrote. There should be more studies conducted to fully characterize the efficacy of bariatric surgeries.
Practice Pearls:
  • This study was conducted to compare long-term results of gastric bypass and gastric band.
  • The data results found that gastric bypass has better long-term outcomes for weight loss, better control for diabetes, hypertension, and dyslipidemia.
