Safety & Efficacy
Bariatric surgery improves obesity-related diseases and reduces the risk of mortality
"Surgical intervention in obesity significantly reduces the risk of DM [diabetes mellitus] and the risk of future mortality and is cost effective."
Bariatric Surgery Centers of Excellence must report outcomes data to a national registry, thereby providing good data to assess the results of the surgery.
Based on reported procedures to the national registry for a period between June 2007 and September 2009, the percentage of serious events following all 3 types of bariatric surgery was below 2%. The percentage of mortality was less than .25%.306
The mortality rate for bariatric and metabolic surgery is lower than for other common procedures such as a laparoscopic cholecystectomy, hip replacement or coronary artery bypass.
While there are risks with any surgery, advances in bariatric surgery over the years and the fact that 90% are performed laparoscopically have reduced the incidence of serious events and/or deaths.
Risk of premature death – reduced 89%302
Over the years, bariatric surgery has progressively become safer for these reasons:290
- Advances in the procedures and techniques
- At least 90% of bariatric procedures are now performed laparoscopically291
- Center of Excellence (COE) accreditation has been established
