dc.description.abstractThe 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
