I had my gallbladder removed in October and was in the ER within two weeks with very severe gastric pain. Went back to the surgeon, went back to the original GI doc, no help. Liver enzymes very high, several ER trips. Finally, one month ago, my family doc prescribed 60 mg per day–usual dose is 15 mg per day–of lansoprazole (Prevacid). Haven’t had an attack since and have been eating real food again, not just oatmeal and broth. Liver enzymes have come down. Currently taking 30 mg per day, still works, so far. Someone else has also posted here that lansoprazole worked, so maybe there’s something to this. Worth a try!
