Abstract:Objective: To investigate a detective methods of choledocholithiasis.
Methods :Using retrospective study methods, a logistic regression descriminant analysis of 16 factors related to choledocholithiasis was made and a relative discriminant model was constructed.
Results:Logistic regression analyses that had sex, history of jaundice or jaundice, the widest inner diameter of choledochus, AST,ALT and the history of cholecystectomy, cholecystolithiasis and pancreatitis included into discriminant model, gave the best predictive result. A test sample showed the discriminant model had a sensitivity of 89.4％, and a specificity of 80.0%.
Conclusions:Discriminant analysis of logistic regression with clinical data is helpful for diagnosis and treatment of choledocholithiasis.It can also increase the accuracy of the predicion of cholecystolithiasis and serve as a clinical guide.
