[B-mode ultrasonography in the diagnosis of appendicitis].
This article reports the ultrasonographic data in the diagnosis of 142 cases of appendicitis. 30 out of 40 cases originally misdiagnosed by the surgeon were proved to be other disease entity by this method preoperatively. Of 102 cases of appendicitis, 95 were accurately diagnosed by ultrasound including 14 cases with entirely atypical history and 7 cases with unusual position. The accuracy of diagnosis made by B-mode ultrasonography was 93.1%. By B-mode ultrasonography, the data of appendiceal diameter, inner diameter and the peri-appendiceal exudate were used to diagnose and classify appendicitis preoperatively, thus the misdiagnose rate went down from 10.6% to 1.8%.
