| Abstract | ||||
| Background: One of the most frequent reasons for acute abdomen that necessitates surgery is acute appendicitis. Even though appendicectomy is the standard treatment, there is a chance of complications following surgery. To assess individuals exhibiting equivocal symptoms, computed tomography (CT) scans have been introduced. Its application might reduce needless intervention by stratifying patients. Objectives: To evaluate the diagnostic precision of contrast-enhanced computed tomography for suspected acute appendicitis. Methods: Seventy-three individuals with probable acute appendicitis (Alvarado score range from 4 to 6) were included in this research. Prior to appendectomy, the patients had preoperative CT scans of their abdomen and pelvis with intravenous contrast. The final pathology was correlated with the CT results. Results: The mean age of the study population 26.7 ± SD 11.9 years old. The incidence of positive appendicitis by intraoperative assessment was 70.5% while the incidence was 79.5 % by definitive pathological diagnosis. CT scan in the preoperative settings had a sensitivity, specificity and diagnostic accuracy of 75.3%, 100% and 80.3% respectively. There were 5 significant CT predictors for acute appendicitis: Distended appendix, thick enhancing wall, fat plane smudging, periappendicular fluid collection and appendicolith. A CT scoring system was created using the significant findings. A score of 2 or more had a 70.5% sensitivity, 100% specificty for diagnosing a pathologically proven acute appendicitis. Conclusion: CT abdomen and pelvis with IV contrast is a useful tool with high accuracy in diagnosing or excluding acute appendicitis. | ||||
