A Study Examines The Benefits And Drawbacks Of Common Weight-Loss Surgeries.


A research team led by the University of Michigan Health discovered that sleeve gastrectomy is safer than gastric bypass among the most common weight-loss surgeries.

The study’s findings were published in the journal ‘JAMA Surgery.’Patients who had a sleeve gastrectomy, which involves removing part of the stomach, had a lower risk of death and complications five years later than those who had their stomachs divided into pouches through gastric bypass surgery.

However, gastric bypass was superior in one area: sleeve gastrectomy patients were more likely to require follow-up surgery, suggesting that gastric bypass is more effective long-term, despite carrying more risks.”It’s really important for patients to understand the risk of significant issues like death, complications, and hospitalisation after these two procedures because that helps inform the decision about which type of bariatric surgery to choose,” said Ryan Howard, MD, the study’s first author and a general surgery resident at Michigan Medicine.

“You could imagine a scenario in which a patient is averse to that risk, and so even if a sleeve gastrectomy does not confer as much weight loss, they may want it because it is the safer surgery,” Howard added.”However, if a patient has a lot of comorbidities and a bypass will provide a better clinical benefit, maybe that risk is worth it,” Howard concluded.Short-term studies have shown that sleeve gastrectomy is the safer option, but this is the largest study to compare the outcomes of the two procedures over a longer period of time.
