Post op 13yrs fistula tract????!!!

Ok so I am now post op Rouxeny and was able to maintain my weight pretty good  until about a year ago.  I just found out I have a fistula tract, a hole from my pouch leading to my old stomach which hasn't been used in 13yrs. I was wondering if anyone else has had this issue due to I thought the suture line totally disconnected the old stomach. I had my surgery open at Albany Medical Center.
