Abstract: Background: Acute appendicitis is the most common clinical diagnosis in general surgery clinics for which patients require urgent surgery. Delayed diagnosis, may cause complications like perforation of the appendix or abscess formation, and misdiagnosis, may lead to unnecessary surgery. To minimize these cases several scoring systems have been developed based on various symptoms, signs, and some basic laboratory investigations. Aims and objective: To compare sensitivity, specificity, positive predictive value, and negative predictive value of OHMANNS SCORING SYSTEM VERSUS HIGH-RESOLUTION ULTRASONOGRAPHY. Materials and methods: A Prospective study was carried out in 50 patients presented with right lower quadrant pain who underwent appendicectomy. Ohmanns Score of each patient calculated using clinical parameters and laboratory findings and HR-USG findings of each patient were noted down preoperatively. After appendicectomy, the specimen was sent for HPE (histopathological examination). Sensitivity, Specificity, Positive predictive, and negative predictive values are then calculated using HPE findings as gold standard. Results: Sensitivity and negative predictive value of HR-USG is higher than Ohmanns Scoring System, whereas Specificity and Positive predictive value of Ohmanns scoring system is higher than that of HR-USG. Conclusion: Sensitivity and negative predictive value of HR-USG is higher than Ohmanns Scoring System, whereas Specificity and Positive predictive value of Ohmanns scoring system is higher than that of HR-USG.
