Treatment is removal of the gallstone from the<unk> <unk>  using ERCP or an intraoperative cholangiogram. In these procedures, a thin tube is introduced into the<unk> <unk> <unk>  to perform a cholangiogram. If<unk> s are identified, the surgeon inserts a tube with an inflatable balloon to widen the<unk> , and the<unk> s are usually removed using either a balloon or tiny basket. A laser can be used to split big<unk> s and make it easier to solve it using laparoscopy. If the either of these procedures is unsuccessful, the<unk>  can be removed during surgery through an incision into the<unk> <unk>  at the location of the<unk>  (called choledocholithotomy). This procedure may be used if the<unk>  is very large or if the<unk>  anatomy is complex. Typically, the gallbladder is then removed, an operation called cholecystectomy, to prevent a future occurrence of<unk> <unk> <unk>  obstruction or other complications.
