Abstract:
Objective To explore the diagnostic value of contrast-enhanced ultrasonic intravenous imaging and cholangiography in the diagnosis of malignant jaundice obstructive. Methods Forty three patients who were diagnosed with malignant obstructive jaundice by contrast-enhanced computed tomography and contrast-enhanced computed magnetic resonance imaging were enrolled in this study. All of them underwent conventional ultrasound, IV-CEUS and IC-CEUS. According to the results of operation, the diagnosis accuracies were compared among conventional ultrasound, IV-CEUS, IC-CEUS and IV- CEUS combined with IC-CEUS. Results Diagnostic accuracy by the conventional ultrasound , IV-CEUS , IC-CEUS and IV- CEUS combined with IC-CEUS were 72.1%(31/43), 83.7%(36/43), 81.4%(35/43) and 93.0%(40/43), respectively. IV- CEUS combined with IC-CEUS was superior to the conventional ultrasound (P = 0.021). There were no significant differences when the conventional ultrasound was compared with IV-CEUS or IC-CEUS alone (P = 0.194 and 0.307). Conclusions Preoperative evaluation by IV- CEUS combined with IC-CEUS can elaborate the intra-cavitary and extra-cavitary changes of malignant obstructive jaundice. The diagnostic accuracy rate could be effectively improved by IV-CEUS combined with IC-CEUS, which can bring favorable clinical benefit.
