RESUMO
Sixty acute appendicitis suspects with unclear clinical picture were examined with high-frequency ultrasound and native CT. The results of the examinations were compared with clinical data, surgical findings and histological evidence. Acute appendicitis was in 39 patients, other diseases of abdominal cavity and small pelvis--in 21. Sensitivity of CT was 95%, specificity--91.3%, accuracy--96.6%. Sensitivity of US was 92.3%, specificity--100%, accuracy--95%. The above parameters for non-invasive diagnostic methods were similar to ones for laparoscopy. Native CT and US are highly precise methods for diagnosis of acute appendicitis. They are preferable in unclear clinical situations, atypical location of the appendix, in children, elderly and aged patients, and in patients with mental disorders.
