Plea for selective operative cholangiography.

Abstract

A prospective study was carried out to evaluate the use of routine operative cholangiography in 382 patients undergoing elective cholecystectomy. Operative cholangiography was performed in 356 patients. In each patient, the presence or absence of clinical and operative indications for common duct exploration was correlated with the result of the operative cholangiography. In 114 patients (32%) there were one or more indications for exploration and only 34 patients showed positive cholangiographic findings and were explored. Ductal stones were found in 25 patients and nine patients had negative explorations. In the remaining 242 patients who had no indication for common duct exploration, normal cholangiogram was obtained in 234 patients and eight had false positive cholangiograms and were explored unnecessarily. No unsuspected common duct stones were detected in the whole series. Based on these results, a plea is made for selective operative cholangiography.
