Abstract

Objectives: to evaluate the role of ultrasound in the diagnosis of acute appendicitis. Subjects and methods: a retrospective, cross-sectional study of 81 cases of acute appendicitis operated at hospital E, with pathological results, preoperatively diagnosed by ultrasound. Results: mean age was 37.4 ± 15.2, youngest was 12, oldest was 93, age group 17-40 accounted for the highest percentage (53.1%), male/female ratio ~ 1.13/1; appendix in right iliac fossa occupied 82.7%; appendix diameter ≥ 7 mm accounted for 79%, wall thickness ≥ 3 mm accounted for 56.8%; peri-appendicular infiltration accounted for 87.6%; fluid in the appendix lumen accounted for 85.2%, the appendix did not collapse when squeezing the probe accounted for 93.8%; fecal stones accounted for 23.4%; the sensitivity of ultrasound for the acute appendicitis was 83.7%, accuracy was 83.9%, positive predictive value was 100%. Conclusion: Ultrasonography had the high value and played an important role in the diagnosis of acute appendicitis, as the first choice imaging modality for clinicians in front of an acute abdominal pain.
