Abstract
Background: Appendix is a blind muscular tube derived from the midgut. During the embryogenic development, in the 6th week appendix and cecum appear as out pouching from midguts caudal limb. Acute appendicitis is one the most common diagnosis made whenever patient presents with right illac fossa pain and mostly encountered in young and middle-aged individuals. The diagnosis and management of acute appendicitis depend on clinical presentation, that is, clinical signs and symptoms. The most common presentations in these cases have abdominal pain along with fever, anorexia, nausea, and vomiting. Various Scoring systems are developed to diagnose acute appendicitis based mainly on the presenting signs and symptoms, but widely none of them are used as an uniform scoring system.

Aims and Objectives: The purpose of this study was to assess effectiveness and comparison of modified Alvarado score and Tzanaki’s Score in the early diagnosis of acute appendicitis.

Materials and Methods: A prospective observational study was done in department of General Surgery JLN Medical College Hospital, Ajmer which included 200 patients presenting with the signs and symptoms of acute appendicitis, clinically. During admission the patients were evaluated by Modified Alvarado score and Tzanaki’s Score and final surgical decision was taken by the treating surgeon. Finally, the scores were compared with the histopathological examination of the surgically operated specimen.

Results: The sensitivity and specificity of Modified Alvarado Score was 84.26% and 72.7%, respectively, with a positive predictive value of 96.15% and negative predictive value of 36.3%. The sensitivity and specificity of Tzanaki’s score was 88.2% and 72.7%, respectively, with a positive predictive value of 96.31% and negative predictive value of 43.24%. The diagnostic accuracy of Alvarado score was 83% and that of Tzanaki’s score was 86.5%.

Conclusions: Our study showed that Modified Alvarado scoring system is a simple tool with limited features for bedside diagnosis of acute appendicitis, but its effectiveness is not as good as that of Tzanaki’s scoring system.

Key words: Acute Appendicitis; Histopathological Examination; Tzanaki’s Score; Modified Alvarado’s Score
