Fistula after RNY?

Hi Evernyone, I have a fistula between my pouch and my old stomach.  Its along the staple lines even though the pouch was completely severed from the remaining stomach. 

I understand that this is relatively rare, Anyone else have the same experience?  If so, what did you do about it?

I have not had pain or other symptoms, I found out during an upper GI while looking into a clinical trial for the RESTORe procedure.

I am scheduled to see Dr. Thompson at Brigham & Women's in Boston to see if he can repair the fistula and my enlarged stoma opening endoscopically.
Regards, Kathy
