ABSTRACT
Objective Comparing the diagnostic values for the malignant obstruction diseases of biliary tract between endoscopic retrograde cholangiopancreatography(ERCP)and MR cholangiopancreatography (MRCP). Methods Parallel analysis for the ERCP and MRCP data of 142 malignancies confirmed by surgery and/or ERCP among 383 biliary tract patients was retrospectively carried out. Results MRCP and ERCP were performed with exploration of 137 cases,showing the total conformity of 96.4%; together with localization conformities of 92.3% and 87.3%,qualitative conformities of 78.5% and 89.8% respectively. Conclusions In diagnosing the malignant obstructing disease of biliary tract,MRCP has the advantages in convenience,safety and low false negative,but with higher false positive than ERCP; however,if combined with ERCP can get higher positive conformity.(J Intervent Radiol,2007,16: 673-675)
ABSTRACT
Objective To study retrospectively the curative effect of emergent transcatheter arterial embolization(TAE)on ruptured liver cancer with hemorrhage. Methods Twenty-three patients with rupture of liver cancer were emergent treated with TAE for massive hemorrhage. Results Twenty-two patients were treated by TAE effectively with good hemostasis and without recurrence of bleeding as well as liver failure, except one referred for surgery due to anomalous vascular route leading to failure of catheterization. Nine of 22 patients accepted more than one time of TAE according to the curative effect and progress of the disease, but reduction of tumor size or necrosis could be achieved in all these patients. Conclusions Emergent TAE is an effective treatment for ruptured liver cancer with hemorrhage, having good effect of hemostasis and providing the possibility for subsequent treatment.
