Weight loss surgery is more effective than previously reported, and getting safer, according to a recent study published online in JAMA Surgery.  The study is an update to a meta-analysis of studies conducted between 1990 and 2003 that was published in JAMA back in 2004. More than 162,000 patients from 164 studies (37 randomized clinical trials and 127 observational studies) were included in the analysis. The study highlights higher remission rates of diabetes and high blood pressure, as well as a lower mortality rate than previously reported.  The key findings included:

  • Higher diabetes remission: 92% of patients in randomized clinical trials experienced diabetes remission after surgery, compared to 86% remission rate found in observational studies, and significantly higher than the 76.8% remission rate reported in the 2004 JAMA study.
  • Better blood pressure: Remission rates for hypertension were about 75%  in both the randomized clinical trials and observational studies, while the remission rate in 2004 was 61.7%.
  • Improved safety: In the new study, 30-day mortality rate was 0.08%, down from the 0.3% in the 2004 report. Complication rates ranged from 10 to 17% and the reoperation rate was about 7%. (Complication and reoperation rates were not reported in the previous meta-analysis).

The results provide further support for offering weight loss surgery as a safe and effective treatment for obesity. At Oregon Weight Loss Surgery (OWLS), we specialize in the 3 most common “restrictive” weight loss procedures: laparoscopic adjustable Gastric Banding, laparoscopic Roux-en-Y Gastric Bypass, and laparoscopic Sleeve Gastrectomy. These procedures are restrictive because they reduce the amount of food your stomach can hold. Patients eat smaller meals, which allow them to lose weight.  While all three are restrictive procedures and performed with laparoscopic techniques, there are significant differences—and each has its own distinct advantages and disadvantages. You can learn more about the procedures and if weight loss surgery may be a good option for you by attending one of our free informational seminars.  Register online here or call our office at 503-227-5050.
