Hi, about a 1 1/2 ago I underwent a major surgery to repair my bile duct strictures, I had suffered from pancreatis from the time the took my gall bladdar until this surgery (1o years), they perfomed a roux en y (not gastric). I now suffer from severe kidney stones, is this a side effect/result of the suregery preformed? I had never experienced anything like this before. They are very painful and mimick the pain of pancreatits.
