Discussion about the necessity of intraoperative cholangiography resta
rted when laparoscopic cholecystectomy was established, The value of c
holangiography was examined in a prospectively randomized study of one
hundred patients, We could show that the routinely performed intraope
rative cholangiography represents a careful, secure and sensitive meth
od for the detection of common bile duct stones, As it is not very tim
e consuming nor linked to high costs we believe it to be unrenouncible
. It allows a detailed anatomic presentation and may be combined with
ERCP for definitive treatment of bile duct stones.
