©2013 UpToDate ® Print Email Balloon extraction of common bile duct stones Left panel shows a balloon catheter being threaded over a guidewire within the common bile duct (thin arrows). At least two gallstones are visible in the distal common bile duct (arrow heads), which is dilated. In the right panel, the balloon has been inflated above a gallstone (arrow), which permits the balloon to drag the gallstone out of the duct. Courtesy of Isaac Raijman, MD.
