Key result
Ultrasonography demonstrated higher sensitivity (92.47%) compared to the Modified Alvarado Score (83.87%) for diagnosing acute appendicitis, with both modalities showing 100% specificity.
Why the study?
Does the Modified Alvarado Score combined with ultrasonography accurately diagnose acute appendicitis in suspected patients?
Observational (n=100)
No
Does the Modified Alvarado Score combined with ultrasonography accurately diagnose acute appendicitis in suspected patients?
Absolute Event Rate: 92.47% vs 83.87%
The Modified Alvarado Score combined with ultrasonography provides high diagnostic accuracy and positive predictive value for acute appendicitis, which can help reduce negative appendicectomy rates.
May support ultrasonography over scoring for appendicitis sensitivity; leaves open need for prospective validation before practice change.
Background: Acute appendicitis is most common cause of pain abdomen. The diagnosis of which remain difficult in many cases. Methods: A 100 consecutive patients suspected of acute appendicitis who were admitted in department of surgery, sardar patel medical college & AGH, Bikaner, Rajasthan. They were prospectively evaluated using the modified Alvarado scoring (MAS) to determine whether or not they had acute appendicitis. The MAS was correlated with USG and histopathological findings. Results: 78 (true positive) patients who had MAS 7 or more had appendicitis on histopathology while no patients (false positive) had a normal appendix; 15(false negative) patients with MAS less than 7 had appendicitis and 7(true negative) had a normal appendix removed.

Samay Singh (2018) conducted an observational in Acute appendicitis (n=100). Modified Alvarado Score and Ultrasonography vs. Histopathology was evaluated on Diagnostic sensitivity for acute appendicitis. Ultrasonography demonstrated higher sensitivity (92.47%) compared to the Modified Alvarado Score (83.87%) for diagnosing acute appendicitis, with both modalities showing 100% specificity.
