Abstract：Objective To discuss the value of contrast-enhanced ultrasound (CEUS) in the Bismuth-Corlette Classification and
preoperative evaluation for hilar cholangiocarcinoma (HC). Methods The clinical data of 42 patients with HC confirmed by surgical
pathological examination were analyzed. Conventional ultrasound and CEUS were performed before surgery. The diagnostic
coincidence rate and resectable evaluation consistency were compared with the results of surgery and pathology. Results The
diagnostic coincidence rate of Bismuth-Corlette classification of HC by CEUS was 95.2% (40/42), which was significantly higher
than that by conventional ultrasound 73.8% (31/42) (χ2=7.372, P=0.006). Combined with hepatic portal lymph node metastasis,
hepatic metastasis, hepatic artery and portal vein invasion, the coincidence rate of preoperative resectability assessment and
intraoperative evaluation for HC confirmed by CEUS was 92.9% (39/42), which was better than that by conventional ultrasound
(69.0%) (29/42), and the difference was statistically significant (χ2=7.721, P=0.005). Conclusion CEUS can show the infiltration
range of the tumor, the extent of invasion of surrounding tissues, blood vessels and lymph nodes. It conducts accurate classification
and resectability assessment of HC, which is of guiding significance for the clinical formulation of a reasonable treatment plan.
