[The value of intraoperative cholangiography].

The 99 intraoperative cholangiography results from the last two years are analyzed. The indications are mentioned, as the intraoperative cholangiography was not used performing every one cholecystectomy. The authors think that the intraoperative cholangiography is necessary before the exploration of the common bile duct. The results are compared with the preoperative i.v./inf. cholangiography findings performed in 95 cases; the rule is, that we do not operate the bile tract without preoperative cholangiography. The diagnostic intraoperative cholangiography findings value that proves the common bile duct obstruction is 0,90, and 0,70 for the preoperative cholangiography. That two diagnostic values relation is 0,95:0,85 for the intraoperative cholangiography. The choledochotomy findings in this group (66%) were controlled by instrumental exploration and even by choledochoscopy. There were no complications in this group performing intraoperative cholangiography.
