You need to have a bile Diversion surgery. You may have to go to the Mayo Clinic or to Boston to find a surgeon that does this procedure.
I had a distal gastrectomy and roux-en-y surgery last March due to bile reflux which was caused from a previous gastroenterostomy to correct my delayed gastric emptying. Anyway, one thing led to another. There can be many side effects to this type of surgery including malabsorption of minerals and vitamins, nausea, dumping syndrome, diarrhea, and others. I have experienced all of the above mentioned, but the dumping syndrome is improving. I no longer have the chronic burning in my stomach which at times was awful and the nausea is usu. not as severe. Am I better for having it done? Probably a little. Since you've already had a gastrectomy with a Billroth ll, you may not have as many side effects as most people. Good luck!
