DIAGNOSTIC ACCURACY IN ACUTE APPENDICITIS: COMPARISON BETWEEN CLINICAL IMPRESSION AND ULTRASOUND FINDINGS
Abstract
A cross-sectional study to determine the diagnostic accuracy of clinical impression and graded compression abdominal ultrasonography in acute appendicitis used individually or complementary to each other was conducted in a busy surgical unit. Eighty-nine cases subjected to categorized clinical impression and ultrasonography preoperatively achieved fairly high sensitivity (84.3% and 81.81% respectively) but low specificity (23.68% and 38.23%) with an overall negative predictive value of 31%, implying it to be a poor indicator to avoid negative appendectomies.References
