Lap RNY Revision?

I have an appt. to see a doctor regarding a revision from Lap RNY to ? Has anyone had this done? Can a revision be done on someone like me? The reason I am seeing a doctor is because after almost 4 years, I am starting to put my weight back on. I want to be checked to make sure that the opening (stoma?) hasn't stretched and to make sure that my staples are still present. What worries me is a pain that I always have on my right side, near the stomach. I am wondering if I can have this revised to a DS? Thanks for your help!
