Pseudoliths, sometimes referred to as sludge, are thick secretions that may be present within the gallbladder, either alone or in conjunction with fully formed gallstones.
Although unusual, it is possible to have a common bile duct stone despite prior cholecystectomy. One study found that in patients diagnosed with choledocholithiasis, 28% had undergone prior cholecystectomy. Such stones are thought to be the result of stones missed at the time of the cholecystectomy, as opposed to the formation of new stones. [3]

If a stricture is identified, put in biliary manipulation catheter with guidewire measuring 0.035 inches and commence balloon dilatation (with balloon sizes of 8, 10, and 12 mm). Using the balloon catheter, the stones are pushed into the duodenum. If the stones are difficult to push, Dormier basket is used to push them into the duodenum.
This inflammation of the gallbladder is known as cholecystitis and is a common indication for surgical removal of the gallbladder, or cholecystectomy. [ 12 ] Occasionally gallstones may become lodged in the common bile duct and obstruct the flow of bile from the gallbladder to the small intestine– this condition is known as ...
