[Intraoperative laparoscopic cholangiography -- when is it useful?].
Since the introduction of laparoscopic cholecystectomy (LC), a decrease in the practice of intraoperative cholangiography (IOC) has been reported. Are there actually reasons for carrying on IOC during LC? Depending on the management of common bile duct (CBD) stones treatment a different IOC regime is recommended. If the single-stage laparoscopic extraction of ductal calculi during LC is preferred, routine IOC is generally necessary to detect all CBD stones for desobstruction via ductus cysticus or choledochotomy. When therapeutic splitting is favoured, including two-stage management with endoscopic desobstruction and later LC, routine IOC can be foregone. However, selective practice of IOC can help to reduce the rates of unnecessary preoperative investigations from 40-60 % to 20 % when postoperative endoscopic desobstruction demonstrates similar success rates of about 95 %. Regarding the preventive character of laparoscopic IOC to CBD injuries, a routine investigation should be adopted by institutions with injury rates > 0.4 % and in the learning phase of young surgeons. For all other institutions a selective practice should be recommended when difficult intraoperative conditions render recognition of the anatomical situation more difficult or for identification of dissected non-bleeding ducts near the triangle of Calot.
