description Background: Decision-making in patients suspected of having acute appendicitis has remained a diagnostic challenge worldwide despite the advances in imaging and appendiceal surgery. There have been efforts to improve the diagnosis of appendicitis using clinical scoring systems. Aim: We evaluated and compared the diagnostic accuracy and role of Alvarado score (AS) and two of its modification (Kalan and Al-Fallouji) in the preoperative diagnosis of acute appendicitis. Materials and Methods: This was a prospective study conducted at the Usmanu Danfodiyo University Teaching Hospital, Sokoto, of all adult patients operated for acute appendicitis from July 2014 to June 2017. The results were analyzed on computer using Statistical Package for the Social Science version 15.Results: One hundred and eleven patients were studied. Sixty-six (59.5%) patients were males and 45 (40.5%) were females. The male-to-female ratio was 1.5:1. The mean age was 23.89 ± 4.93 years. The AS sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of 90.3%, 83.3%, 96.6%, 62.2%, and 89.2%, respectively, were similar to the findings of Kalan score (90.3%, 83.3%, 96.6%, 62.5%, and 89.2%, respectively) and Al-Fallouji score (96.8%, 66.7%, 93.8%, 80%, and 91.9%, respectively). The receiver operating curve and area under the curve show that Alvarado, Kalan, and Al-Fallouji are accurate scores in the preoperative diagnosis of acute appendicitis with an area under the curve of 0.88, 0.86, and 0.85, respectively. Conclusion: Kalan and Al-Fallouji scores have comparably good diagnostic accuracy as the AS among our patients. Any of these scores can be used as an adjunct in the preoperative diagnosis of acute appendicitis.
