Laparoscopic ultrasound as the primary method for bile duct imaging during cholecystectomy.
Intraoperative fluorocholangiography (IOC) has been the standard method for bile duct imaging during cholecystectomy. Laparoscopic ultrasound (LUS) has been evaluated as a possible alternative, but has been used less frequently. The authors examined the evolving use of these two methods to assess the relative utility of LUS as the primary method for routine bile duct imaging during laparoscopic cholecystectomy (LC). ⋯ With moderate experience, LUS can become the primary routine imaging method for evaluating the bile duct during LC. It is as reliable as IOC for detecting choledocholithiasis. In addition, LUS can locate the common bile duct during difficult dissections. On the basis of this experience, LUS is used currently in nearly all LCs and is the sole method for bile duct imaging in 75% of these cases. IOC is used as an adjunct to LUS when LUS imaging is inadequate, when stronger clinical indicators of choledocholithiasis are present, or when biliary anatomy remains uncertain.
