What is mini gastric bypass ?

I had gastric bypass surgery almost a year ago.  I just came by this messageboard and out of curiosity was wondering what a mini gastric bypass is.  Could someone explain to me what it is?  How is it different than RNY?

hanks for any information that you want to share.
