F. C. Laing, M. C. Frates, V. A. Feldstein, R. B. Goldstein and S. Mondro
The purpsoe of this study is to discuss the causes and sonographic appearances of blood in the gallbladder and biliary tree. Over a 12 year period, 18 patients with hemobilia had ultrasonographic examinations at one of three hospitals. Hemobilia was categorized as traumatic (50%), spontaneous (28%), or inflammatory (22%), with coagulopathy present in half of the cases. The sonographic appearances of intracholecystic blood varied, but with the exception of a single case, masslike intracholecystic material was present. Biliary dilatation occurred in five patients, with echogenic material visible in the extrahepatic bile duct in three of these cases. |
