Acute appendicitis is a common surgical condition that requires prompt diagnosis. However adecision to operate based on the clinical suspicion alone can lead to removal of the normalappendix in 15-30% cases. Besides the modern imaging techniques, scoring systems, based onclinical signs and symptoms and routine laboratory assessments, have been used as a diagnosticaid. However, differences in sensitivities and specificities were observed if the scores were appliedto various populations and clinical settings. The purpose of this paper is to assess the validity of theOhmann score and the correlation of ultrasound in diagnosis of acute appendicitis. A total of 80patients were enrolled in this study, 52 male patients and 28 females patients suspected of acuteappendicitis that were admitted, investigated and treated. After detailed examination andinvestigations, the Ohmann score was applied to these patients. A cut off point of 9 was taken.Patients were divided into two groups, group I score of ≥ 9 and group 2 score of < 9. This studywas conducted at SDM College of Medical Sciences and Hospital Dharwad.Proportion of truepositive for score ≥ 9 is 86.9%, Proportion of true negatives for score <9 is 87.1%. Sensitivity andspecificity of this study being 96% and 66.7%, positive predictive value and negative predictivevalue being 82.8 % and 90.9% respectively. Diagnostic odds ratio being 48 and P value of <0.005.The high scores in Ohmann scoring system is dependable aid in the early diagnosis of acuteappendicitis. Combined with ultrasound, the Ohmann scoring system has high sensitivity andspecificity, in the prediction of acute appendicitis.
