Abstract

Objective: To compare the diagnostic value of ultrasonography(US) with CT for pediatric acute and chronic appendicitis. Methods: Clinical data for 134 patients pathologically verified appendicitis at the age of 5 to 12 years old were retrospectively analyzed to compare the value of preoperative CT(n=134) and US(n=134) in the diagnosis and antidiastole of this disease from January 2013 to March 2014. The sensitivity of the two modalities was compared in the diagnosis of acute appendicitis and chronic appendicitis, acute simple appendicitis and acute non-simple appendicitis. Results: The diagnostic value of CT for acute appendicitis was significantly better than that of US. The sensitivity of US vs. CT were 69.75% vs. 81.51% in diagnosing acute appendicitis, respectively. Higher sensitivity was shown by CT in diagnosing acute simple appendicitis compared with US(84.38% vs. 62.50%, respectively; P＜0.05） while no difference was found in diagnosing acute non-simple appendicitis(87.36% vs. 82.76% respectively, P＞0.05) or chronic appendicitis(66.67% vs. 40.00% respectively, P＞0.05). Conclusions: Ultrasonography can be considered as the first choice for the diagnosis of pediatric acute or chronic appendicitis. When US revealed negative or equivocal results with progressively aggravated symptoms, a CT scan was then needed.
