Acute appendicitis: Factors associated with inconclusive ultrasound study and the need for additional computed tomography.

Purpose: To identify variables associated with inconclusive ultrasound examination and the need for further abdominopelvic computed tomography (CT) examination for the diagnosis of acute appendicitis.

Materials And Methods: A total of 105 adult patients with acute appendicitis were included. There were 55 patients (38 men, 17 women; mean age, 23±9 [SD] years; range: 15-58 years) with a diagnosis of acute appendicitis using ultrasound alone and 50 patients (30 men, 20 women; mean age, 31±14 [SD] years; range: 16-83 years) who required further CT.

Does IV contrast extravasation on CT in anticoagulant-related rectus sheath and iliopsoas hematoma predict hematoma expansion and patient outcomes?

Objective: The purpose of the study was to evaluate if IV contrast extravasation on CT in anticoagulant-related rectus sheath and iliopsoas hematoma predict hematoma expansion and patient outcomes.

Materials And Methods: All patients presented with anticoagulation-related spontaneous IP hematoma or RS hematoma and who underwent contrast-enhanced CT exploration, with injection of a contrast material, from January 2012 to January 2015 in our institution were included in this study. Considering the retrospective nature of our study, our institutional review board judged our study to be exempted from ethical approval and no patient consent was required.
