Difference?
Ok....It maybe a silly question among all the know-it- alls here. But I would like to know the difference between a gastric bypass and a "mini" gastric bypass. I mean the surgical/ procedural difference. What is done in one that is not done in the other..?

There are a few differences that I can think of right off the top of my head;
- There is only one anastomosis in MGB vs. RNY.
- The new stomach that is created during MGB is more like a 4 oz to 6 oz sleeve rather than a 2 oz pouch as in RNY.
- The new stomach in MGB is created along the lesser curvature of the stomach which is less elastic tissue and less likely to stretch over time. The RNY pouch is created along the greater curvature.
Here is a good research article that describes outcomes of both MGB and RNY: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1357700/ . The researchers conclude that "both LRYGBP (RNY) and LMGBP (MGB) are effective for morbid obesity with similar results for resolution of metabolic syndrome and improvement of quality of life. LMGBP(MGB) is a simpler and safer procedure that has no disadvantage compared with LRYGBP at 2 years of follow-up.
Happy researching :)
