Objective  To evaluate the clinical value of intraoperative cholangiography.Methods  From Oct.1993 to Oct.2001,737 cases of cholecystectomy divided into three groups were analyzed retrospectively.Results  In 312 cases of cholangiography groups,135 cases were explorated in the common duct according to the intraoperative cholangiography,and the positive rate of choledocholith was 94  1%.In 114 cases of direct exploration groups the positive rate of choledocholith was 53  5%.In 311 cases of simple cholecystectomy groups,there were three postoperative residual calculus in biliary tract.Conclusion  Intraoperative cholangiography can avoid unnecessary exploration in the common duct,reduce the residual calculus in the biliary tract,decrease the injury of biliary tract and increase the curative rate of cholelithiasis,which are of great practical value in clinic.
