Endoscopic retrograde cholangiopancreatography (ERCP) may be useful for visualizing the anatomy in patients at high risk for gallstones if signs of common bile duct obstruction are present. A study performed by Sahai et al found that ERCP was preferred over endoscopic ultrasonography and intraoperative cholangiography for patients at high risk for common bile duct stones undergoing laparoscopic cholecystectomy. [33]

Disadvantages of ERCP include the need for a skilled operator, high cost, and complications such as pancreatitis, which occurs in 3%-5% of cases.
