Enlarged Jejunum???

I am 6 years post op Gastric Bypass Surgery and I am doing great! I now have lost a total of 160lbs and am weighing in under 200lbs.  I am at 195 and my personal goal weight is 175 so I feel that it is really reachable.  The GBS had blessed me with 2 baby girls and shortly after the 2nd I went in for a MRI for back pain and they found a tumor on kidney that turned out to be cancer.  That was 3 years ago.  Recently I went in for my 3 year check up and found that I have an "enlarged jejunum" but they don't know what that means and my regular PCP said since the GBS switched everything they don't even know where it is it and they have never heard of this before.  Has anyone eles had any problems with their Jejunum?  Any information would be helpful and I would also appreciate prayers that is it NOT cancer again.  Thank you all and good luck on your journey.

 You have posted this on the BPD board, which is different from RNY (gastric bypass). I'd re-post on the main or RN board. Many of the WLS vets have recently left here, but can be found at the place in my soggy line, and I personally would go over there and ask them.
