[|Human|] Had gallbladder removed March 2012. Last 4 months have developed pain under right ribs (lower, almost at the bottom of ribcage), almost constant gas, and I can at times feel my right side twitching. I take Nexium and Carafate for GERD and Welchol when needed for excessive bile , which I get frequently since the GB surgery. I had a colonoscopy (clear) and endoscopy (minor gastritis, 3cm of Barretts and 1 diverticulosis ) last May. Im concerned about the gas and pain under right side lower ribs. It is the same type pain I had prior to gallbladder removal.
[|AI|]  Hello! Thank you for the query. Your symptoms are most likely caused by stones in the bile ducts. Adhesions which has appeared after the surgery are also possible. I suggest you to have blood work, liver tests (AST, ALT,GTP, AP), amylase, bilirubin, urine amylase and abdominal ultrasound. If stones will be found, ERCP procedure will be necessary and will cure these conditions. If no findings in these tests, abdominal CT should be performed to see if the pancreas is fine and if there is no other things inside the abdominal cavity. Hope this will help. Regards.
