Exploratory w/ Possible Revision scheduled

I saw Dr. Needleman on Tuesday and he has me scheduled for an exploratory surgery on the 19th. He's going to check everything from the pouch and old stomach all the way through my intestines. I hope he finds the problem! I have more unanswered questions than anything - could be lap or open, could go home the same day or be admitted, could get revised with a shorter common channel or not ... etc etc .... it's killing me!! Anyone else ever had an "exploratory" done? My original RNY was in 2003 ... so so many problems going on right now!
