Abstract
The best predictors for the presence of common bile duct stones (CBDS) are cholangitis, jaundice, and direct visualization of stones with ultrasound. In the setting of high suspicion of choledocholithiasis, endoscopic retrograde cholangiography (ERC) is indicated because when CBDS are identified, it allows immediate therapy in the same sitting. If there is a moderate probability of choledocholithiasis, endosonography or magnetic resonance cholangiopancreatography are the first-line options. In patients with gallbladder stones and CBDS, preoperative ERC with or without endoscopic sphincterotomy (ES) is widely recommended as a standard approach. The interval between that and laparoscopic cholecystectomy (LC) should be at least 24 h (<6 weeks) to exclude possible complications due to the ERC/ES. In the setting of open cholecystectomy, open bile duct surgery is significantly superior to ERC with sphincterotomy in achieving common bile duct clearance and is the method of choice. Only in centres with advanced laparoscopic expertise is the laparoscopic removal of CBDS an equivalent treatment option.
