Adult intussusception: presentation, management, and outcomes of 148 patients.

Background: Intussusception is a predominantly pediatric diagnosis that is not well characterized among adults. Undiagnosed cases can result in significant morbidity, making early recognition important for clinicians.

Study Objectives: We describe the presentation, clinical management, disposition, and outcome of adult patients diagnosed with intussusception during a 13-year period.

CT of small-bowel ischemia associated with obstruction in emergency department patients: diagnostic performance evaluation.

Purpose: To retrospectively evaluate the diagnostic performance of computed tomography (CT) for detection of small-bowel ischemia in emergency department patients with abdominal pain and to compare the prospective interpretation with a retrospective interpretation by using surgical or pathologic findings as the reference standard.

Materials And Methods: The HIPAA-compliant study was approved by the institutional review board, and patients consented to research authorization. Sixty patients (61 examinations) (25 male, 35 female patients; median age, 67 years; range, 0.

Differentiation of nonperforated from perforated appendicitis: accuracy of CT diagnosis and relationship of CT findings to length of hospital stay.

Purpose: To determine retrospectively the sensitivity and specificity of computed tomographic (CT) signs in differentiating acute nonperforated appendicitis from perforated appendicitis and to compare CT findings with the length of hospital stay.

Materials And Methods: Institutional Review Board approval was obtained for this study, and patient informed consent was obtained for record review for research purposes. Two radiologists were blinded to patient identification but were informed that all patients presented to the emergency department with abdominal pain and underwent appendectomy.
