The importance of the real-time fluoroscopic intraoperative direct cholangiogram in the laparoscopic cholecystectomy using a new instrument.
OBJECTIVE
Laparoscopic cholecystectomy (LC) has become an accepted standard operative technique for gallstone treatment worldwide. On the other hand, complications, such as bile duct injuries, have been reported recently with the expansion of indication for LC. Intraoperative cholangiogram (IOC), to minimize the risk of bile duct injury, is now considered to be essential for safe LC. There are disadvantages to IOC such as increased operating time, the possibility of bile duct injury and the difficulties of manipulation.


METHODS
We have developed a method for real-time fluoroscopic cholangiograms using a new instrument designed by our group for safe LC. First, a round-tip stylet is inserted through a sheath to coax it gently through the spiral valves of the cystic duct. Secondly, the stylet is removed and the cholangiogram catheter is inserted smoothly. Digital C-arm fluoroscopy provides "real-time" imaging of biliary tree. As a result, we became able to obtain a clear cholangiogram easily in a very short time.


RESULTS
In the first 136 patients, direct cholangiograms were attempted in 106 cases and successfully completed in 102 cases (96.2%).


CONCLUSIONS
With the development of real-time fluoroscopic intraoperative direct cholangiogram, we are able to cope with bile duct injuries and anomalies, and unsuspected bile duct stones.
