A new analysis looked at how well a newer type of weight-loss surgery, called single-anastomosis sleeve ileal (SASI) bypass, works compared with other common bariatric procedures. The researchers combined results from 1,603 patients who had SASI, sleeve gastrectomy, one-anastomosis gastric bypass, or Roux-en-Y gastric bypass. They focused on weight loss after 12 months.
The analysis found that people who had SASI bypass lost an average of 35.9 kg (about 79 pounds) in the first year. This is a large amount of weight loss, but the researchers caution that the quality of the evidence is low to very low. That means the true effect could be different.
The study included both randomized trials and non-randomized studies, which can make the results less reliable. Also, the researchers did not report on safety issues like complications or side effects, so it is not clear how safe SASI is compared with other procedures.
For anyone considering weight-loss surgery, this finding is promising but not definitive. More high-quality studies are needed to confirm how well SASI works and to understand its risks. Always talk to your doctor about the best options for your situation.
