Why mini gastric bypass over RNY?

I got banded in October 2007.  I initially lost 35lbs and have gained 20 of it back.  I am looking into revision and really can't fingure which is the way to go.  Mini or RNY.  I have looked at all the pictures and see how they are done and can't see much of a difference.  Can someone explain what makes the mini differnet from the RNY other than the time it takes to do it.  What is the difference between they way the bypass is done with the RNY compared with the loop in the mini.  Also, what about the complications with digestive juices that occured with the original loop procedures in the past.

Finally, does anyone know if the lapband has to be removed first, in a seperate surgery, or can the reversion all be done in one surgery?

Hi

Basically the connections are different and the reconnection site is different.  In the MGB, you don't need the "Y" connection.  Also in the MGB, about seven feet of the small intestines is bypassed.  In the RNY, I think about 13 inches is bypassed.  The MGB's basic claim to fame is its revisability and reversability. Plus with that much of a bypass, weight loss is good.  Keep in mind everyone is different and everyone loses at a differernt rate.

There has been only a few issues with reflux with the MGB.  Mostly it is due to what is eaten and bad food choices.  I think both share that side affect. 

I think yes, they both can be done at the same time.  You would have to check with your surgeon. A good website to learn more is http://clos.net.
