Ultrasonography findings may also aid clinicians in differentiating complicated from uncomplicated appendicitis, which in turn guides the decision making regarding whether to administer antibiotic therapy first or initiate and perform appendectomy. [51] In a retrospective, blinded study, the medical records of 119 patients with acute appendicitis were reviewed, of which 32 patients had complicated appendicitis (including gangrenous, with or without perforation). Investigators found that the only significant independent predictor of complicated appendicitis was loss of the normally echogenic submucosal layer, with 100% sensitivity and 92.0% specificity. [51]
