Accurate Diagnosis Of Acute Appendicitis By New Scoring System, A One Year Study

Abstract

Background ABSTRACT Acute appendicitis is common surgical emergency. Accurate diagnosis and timely intervention is very important to reduce the morbidity and mortality. The diagnosis of acute appendicitis is primarily clinically based on signs and symptoms supported by investigations. In an attempt to increase the diagnostic accuracy numerous scoring systemshave been developed. The new scoring system was formulated to develop as a simple and reliable scoring system with high diagnostic accuracy. Objective The objectives of the study were to evaluate the predictability of new scoring system in diagnosis of acute appendicitis and compare its accuracy with histopathological report. Methods A prospective non ranadomized study was conducted in 100 patients with clinical diagnosis of acute appendicitis undergoing emergency appendectomy over a period of 1 year. The new score was obtained at the time of admission. Histological diagnosis of acute appendicitis was considered as final diagnosis. Results New score ( ≥13) was 82.9% sensitive and 81.1% specific , positive predictive value of 79.5% and negative predictive value of 84.3%, in diagnosing acute appendicitis with an overall diagnostic accuracy of 82%. IV Conclusion Acute appendicitis is a common surgical emergency. Good clinical judgment aided by investigation, scoring system can help to reduce the negative appendectomy rate. The new scoring system can be used as effective modality to establish the accurate diagnosis of acute appendicitis.
