dc.description.abstract | The aim of this study was to evaluate the sensitivity and specificity of ultrasound in the diagnosis of acute appendicitis at Al-Shefa hospital, Gaza Strip, Palestine. Patients who had appendicitis diagnosed by ultrasound over the study period [n = 180] underwent surgical excision of the appendix. The negative appendectomy rate was low, with only 4.4% [8/180] false positives. A significantly higher false diagnosis rate [False negatives + false positives] was obtained in female patients than in males: 38.5% versus 6.2%. A high proportion of falsely diagnosed cases had abnormal weight [overweight or obese] [82.1%]. The overall sensitivity and specificity of ultrasound, using surgical outcome as the gold standard, were 84.8% and 83.3% respectively, and the positive and negative predictive values were 93.3% and 66.7% respectively. Sensitivity and specificity were higher in males [95.7% and 88.2% respectively] than females [84.6% and 71.4% respectively] | EN |
