Abstract: 【Abstract】〓Objective〓To investigate the clinical effect of digital tomosynthesis on diagnosis of bile duct residual stone. Methods〓Thirty-one patients with hepatolithiasis were performed surgical treatment and stayed the biliary drainage tube after operation. All of patients received both abdomen digital radiography and digital radiography examination. The scores of DR and DTS imagines were analyzed the bile duct resident stones under the standard of choledochoscopy exploration. Results〓The sensitivity,.specificity,.accuracy of bile duct resident stones analyzed with DR imagines were 72%,.33.3%, 64.52%, respectively, while for DTS imagines were 88%, 66.7%, 86.67%. The score of DR imagines was 3.03±0.87,while that of DTS imagines was 4.03±0.79,.and there was statistical difference between two groups (P<0.01). Conclusion〓The clinical efficacy of DTS was better than that of DR, as showed higher sensitivity, specificity, accuracy of bile duct resident stones.
