Question: Is there a difference in weight loss between laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass in patients with morbid obesity?

Conclusion: This study did not find a significant difference in weight loss between sleeve gastrectomy and gastric bypass at 5 years of follow-up after surgery.

And M-L.S. I'm going to hang around 5 more years with you so we'll find out for certain, won't we? My surgery will give me a renewed lease on life and I may live a long long time!???

@Frustr8 I'm going to hold you to that promise.

This study knocks the wind out of the widely-held claim that gastric bypass is superior to the sleeve in terms of greater weight loss.

Darn! And here I was feeling all "abdominally" superior and crap...

Interesting article

I think people forget that the sleeve is part 1 of 2 (DS - the most malabsorptive surgery possible) and the efficacy was so widespread in superobese patients part 2 was never needed.
I decided to go with the sleeve because I could just convert to DS later (but I believed it should not be necessary unless GERD - but I have no history, we'll see in 5 yrs))

Findings In this randomized clinical trial that included 217 adults with morbid obesity, percentage excess body mass index loss in patients undergoing sleeve gastrectomy compared with gastric bypass was 61.1% vs 68.3% after 5 years, a difference that was not statistically significant after adjustment for multiple comparisons.

We've been saying for years...

With bypass you'll lose about 70% of your excess weight....with Sleeve, you'll lose about 60% of your excess weight.

If anything, the findings of this very small study...confirm this.

@Creekimp13 Thank you for breaking it down. I pretty much just hit the highlights of the study, so it's great that you're able to pull out the numbers and get to the core of the study. This is definitely good news for those who've opted for the sleeve.
