Sonography in the diagnosis of acute appendicitis.

Am Fam Physician · 1991

Where this comes from

Abstract

Acute appendicitis can be a diagnostic dilemma. The classic triad of leukocytosis, pain at McBurney's point and a history compatible with appendicitis has a diagnostic accuracy rate of only 80 percent. Ultrasonography, combined with this triad, can improve the diagnostic accuracy, decreasing the negative laparotomy rate from 20 percent to less than 10 percent.
