For what it's worth, I'll pray for you and your wife, Justin.
I concur with the other poster who advised your wife should stay away from fatty foods. My father had his gal blatter removed when I was a child, and greasy food is a no-no, both now and after the gal bladder is removed (though I've heard they don't always remove them nowdays; there are ways to dissolve the stones without removing the gal bladder itself.) To this day, my father doesn't do too well eating things like this.
