Abstract
A positive US finding can prevent further delay of the diagnosis of acute appendicitis (AA), but what is the value of a negative test? A US examination of the whole abdomen was performed in 279 patients clinically suspected of having appendicitis. In 86 of the 279 patients who had no evidence of appendicitis sonographicallym we tried to exclude appendicitis by an added effort to find the normal appendix or a condition mimicking AA. Of these 86 patients, 44 had another disease confirmed sonographically. The normal appendix was visible in 53 cases. Using the combination of these signs appendicitis could be excluded in 66 cases (76%). None of the ultrasonographically visualised normal appendices proved to be inflamed surgically. In 5 cases differential pathology coexisted with appendicitis. The best way of excluding AA is the visualisation of the normal appendix in its whole length, which was possible with forced search in 62% of cases.
