Laparoscopic ultrasound has shown some promise as a primary method for bile duct imaging during laparoscopic cholecystectomy. [17] Yao et al were able to evaluate the common bile duct with laparoscopic ultrasound during laparoscopic cholecystectomy in 112 of 115 patients (97.4%) with cholelithiasis.

In patients who were categorized preoperatively as having a low probability of bile duct stones, the occurrence rate of stones was found to be 7%; in those who were preoperatively assessed as having an intermediate probability of such stones, the occurrence rate was 36.4%; and in those who were rated with the highest probability of bile duct stones, the occurrence rate was 78.9%. [17]

The investigators suggested that as experience increases with laparoscopic ultrasound, this method may become routine for evaluating the bile duct during laparoscopic cholecystectomy. In addition, Yao et al advised mandatory aggressive preoperative evaluation of the common bile duct in those who are suspected to have an intermediate or high risk of having choledocholithiasis.
