Differences between inflamed and non inflamed appendices diagnosed as acute appendicitis.

Background: Despite the great advances in diagnostic methods, the incidence of the surgical removal of a morphologically normal appendix in patients with clinical and complementary signs of acute appendicitis continues to exceed 20%. This study aimed to compare the clinical, laboratory, and ultrasound findings of inflammatory and noninflammatory appendiceal disorders diagnosed as acute appendicitis.

Methods: The medical records of 208 patients with clinical, laboratory, and ultrasound findings indicative of acute appendicitis were studied.
