title: An evaluation of routine operative cholangiography.
abstract: The value of routine use of operative cholangiography was evaluated in 225 patients. In 65 patients (29%), there was one or more clinical or operative indications for common duct exploration and only 21 cases showed positive cholangiographic findings and were explored. There were four negative explorations in this group. In the remaining 160 patients who had no indication for common duct exploration, 157 had a normal cholangiogram and three had false positive cholangiographic findings and were explored unnecessarily. If operative cholangiography had been performed only on those patients with clinical or operative indications for common duct exploration, no ductal stone would have been missed. A selective use of operative cholangiography is advocated and the investigation should be restricted to those patients with clinical or operative indications for exploration of the common bile-duct.
