A technic of intraoperative contact cholangiography is described in which a sterile wrapped film is placed behind the mobilized duodenum and common bile duct. In series of 120 cholecystectomies this technic, in conjunction with conventional cholangiography, allowed a low rate of exploration of the common bile duct (15 per cent) and has detected otherwise unsuspected stones in two patients.
