(1) Lintula scoring system is based solely on clinical examination. This might improve the clinical outcomes in adults with suspected appendicitis. A study was conducted on 50 patients suspected of having acute appendicitis were admitted in surgery department. The variables of the Lintula score were recorded and the sum of the score for each patient was calculated. Patients were treated according to standard protocol decided by consultant. The result of the score will be compared to intraoperative diagnosis using chi square test.After comparing positive and negative appendicitis with positive and negative Lintula scores, sensitivity and specificity of Lintula scoring system in diagnosis of acute appendicitis were found to be 55% and 90% respectively. The positive predictive value and diagnostic accuracy of the test has been found to be 95.65% and 80% respectively. (p value <0.05).
