hi, my father had elevated liver enzymes, especially bilirubin around 3.7, admitted to the hospital with sharp abdominal pain. after all the tests performed, gallstone 0.3 cm was found and removed during ERCP test. Inflammation and infection around the area were the sharp stone was is now treated with Cipro+Flagyl. 2 days after the gallstone removed, pain is gone, but bilirubin levels are not going down. Any ideas why?
