Abstract

OBJECTIVE: The introduction of laparoscopic cholecystectomy (Lap-chol) has induced routine cholangiography to map the biliary tree and identify common bile duct (CBD) stones. However, the use of more selective criteria for performing intraoperative cholangiography (IOC), drawbacks of IOC and experience with laparoscopic ultrasonography (LU) re-introduced intraoperative ultrasonography for the CBD. The purpose of this study was to compare the accuracy of LU and IOC to identify the anatomy of the CBD and the presence of stones. METHODS: A total of 50 unselected patients undergoing elective laparoscopic cholecystectomy were evaluated by LU and IOC. Stones were found in three patients by IOC and could be confirmed by ultrasonography and CBD exploration in two. RESULTS: Anatomic definition of the biliary tract and success of the procedure was better for LU (90 and 98%) than IOC (86 and 72%). CONCLUSION: For Surgical groups with experience in LU this technique appears to become the standard technique to identify the anatomy of the CBD and assessment of CBD stones.
