Ultrasonography in the diagnosis of gallbladder carcinoma.

Sonographic examination of the gallbladder (GB) was performed in 21.646 patients. A histopathologically documented gallbladder carcinoma (GBC) was present in 59 patients (0.27%). Five different sonographic patterns were revealed with differences in number of associated findings, echo pattern and correct preoperative diagnosis. The sonographic diagnosis was correct in 59% and retrospective diagnosis in 65%. Most of the sonographically detectable GBC were inoperable (90%). 15 fine-needle biopsies were positive in 100% and reduced the number of explorative laparotomies. The survival rate was 3 days to 4 years after the first sonographic examination.
