DETERMINATION OF DIAGNOSTIC COLOUR DOPPLER SONOGRAPHIC ACCURACY IN ACUTE APPENDICITIS.

As acute appendicitis is the most common etiology of acute abdomen. This study was done in order to determine sensitivity, specificity, and accuracy of colour Doppler sonography in diagnosis of acute appendicitis.

Materials & Methods: 164 patients clinically suspected to acute appendicitis underwent preoperative colour Doppler sonography and the presence of blood flow in the wall of appendix was indicative of positive result of the study.

Results: Sensitivity, specificity, and accuracy of the sonography were 100%, 94.4% and 98.8% respectively. PPV and NPV of the study were 98.4% and 100%.

Conclusion: Colour Doppler sonography is a very accurate method for diagnosis of acute appendicitis but non visualization of blood flow in the wall of appendix or RLQ is against the diagnosis of acute appendicitis.
