OBJECTIVE: To evaluate the efficiency of ultrasound diagnosis in detecting and staging @entity201 . MATERIAL AND METHODS: An ultrasound study (USS) was conducted in 120 @entity1 aged 19 to 84 years with @entity201 . The @entity1 were divided into 3 groups by the location of a @entity5 process: 1) 47 (39.2%) @entity1 with @entity5 ; 2) 49 (40.8%) with portal duct or @entity6984 ; 3) 24 (20%) with distal one. Ninety (75%) @entity1 were operated on; the others underwent minimally invasive X-ray surgical interventions as percutaneous transhepatic cholangiostomies. The data of ultrasound diagnosis were compared with the results of other studies, intraoperative assessment and morphological examination of a removed gross specimen. RESULTS: A @entity5 was detectable by USS only in 90 (75%) @entity1 ; its sensitivity was 100% for @entity201 ; 69.4 and 37.5% for portal duct and distal ones, respectively. It is most difficult to diagnose @entity189 of the common bile duct. USS reveals no semiotic signs of @entity201 , which could distinguish the latter from other @entity96 . The specific features of the infiltrative growth of a @entity1126 , such as hyperechoic infiltration along the external outlines of the ducts or @entity2617 during thickening of the duct walls, were ascertained. The sensitivity of intraoperative USS in identifying @entity1419 was 100%. That of USS in detecting lymph node @entity3 was 61%; developed the semiotics of altered metastatic lymph nodes. CONCLUSION: The findings have indicated the high informative value of ultrasound diagnosis in determining the dilatation of the bile ducts and the spread of a @entity5 to the liver and lymph nodes. It is recommended that the indications for intraoperative USS should be expanded in @entity201 to define the extent of @entity189 .
