How many have had a hida scan? My GI says that he thinks my gallbladder may not be functioning properly because the CT showed that the gallbladder is enlarged at the "neck". I have no idea what this means but my doc also said. 50/50 chance removal of the gallbladder will help the pain. Do I really want to do this. How many have had good results after gallbladder removal? He is kind of hinting that if I can control the problem without surgery I should. What do you think?
