Aims & Objective:- To estimate the accuracy of ultrasonography in diagnosis of acute appendicitis and its

correlation with histopathological examination.

Materials & Methods:- Patients who were suspected having acute appendicitis and operated based on clinical and imaging 􀃶ndings were

included in this study. Findings of histopathological examination of the operative specimen were then correlated with ultrasonography

􀃶ndings.

Results:- Out of the 141 patients included n this study 101 patients were found to have acute appendicitis on histopathological

examination. Ultrasonography was shown to have sensitivity 70.29%, speci􀃶city 92.5%. Sensitivity was lower when cut off value for

appendicular diameter was increased to 7mm (62.3%).

Conclusion:- Ultrasound should be considered 􀃶rst line investigation in suspected acute appendicitis because of its real time nature,

availability and ease of interpretation. Cut off value for appendicular diameter should be 6mm to impart higher sensitivity.
