I understand that the number 1 choice for successful removal is performing a Cholecystectomy which is a full removal of the gallbladder. My question is are there any other non surgical methods in removing stones if the size is within 2cm? I heard that the use of shockwaves can also be utilized to dissolve the stones? - I am curious because I have noticed an increase in gallstone cases and was also curious if there are any known airline pilots that have this problem and how they dealt with it. And what is the best way to prevent it?
