[Selective use of intra-operative cholangiography in gallstone surgery]

The authors report their experience of the use of intraoperative cholangiography in 350 operations for biliary stones. The cholangiography was performed on all 52 patients with preoperative diagnosis of stones in CBD. In the 298 patients with gallbladder stones intraoperative colangiography was performed in 32 times, on the basis of previous jaundice, pancreatitis, microlithiasis, enlarged cystic duct or choledochus, and suspected palpatory reports of hepatic duodenal ligament. Intraoperative colangiography showed stones in all the patients of the first group and in 8 (25%) of the second. No patients reported disturbances attributable to residual stone with an average follow-up of 6 months.
