Revision from RNY bypass to Distal bypass-Question

I just got an approval letter to do the distal bypass surgery. Has anyone gone from a RNY Bypass to a distal bypass. If so can you tell me the good, bad, and ugly. All the things that the doctor may not have told me. I'd like to get some real life experiences and views from people. Thank you for your help.

Do you mind if I ask which surgeon and where they practice? Im looking for a surgeon to do revision and am having a terrible time finding one that will do it.

I, too, would like to hear from someone that has had this procedure.

Thanks!
