<s>[INST] Im trying to decide on a course of action after finding out that I have an immobile gallstone in the neck of my gallbladder. I would like to avoid surgery if possible (I know the procedure is relatively simple). Im wondering if the gallstone could be dissolved or if it could become mobile and somehow exit the neck, returning to the body of the gallbladder. [/INST] HIT hank for asking to ChatDoctorIf it is asymptomatic and does not cause cholecystitis jaundice, or cholecystitis, then it may not require surgery in emergency, but if it's creating any kind of such problem then you need to go for surgery, you can try ursodeoxycholic acid gives good result, but you have to consult the physician for exact dose and duration because it all depends upon the clinical sign and symptoms, and imaging studies, else you will have to go for surgery if it fails to respond, take care </s>
