We evaluate the accuracy of point-of-care ultrasonography compared with computed tomographic (CT) scan and assess the potential time-saving effect of point-of-care ultrasonography in diagnosing small bowel obstruction.

This was a prospective observational study of a convenience sample of patients with suspected small bowel obstruction in an academic emergency department (ED). Physician sonographers were blinded to clinical data, laboratory results, and CT scan findings. Point-of-care ultrasonographic findings of small bowel obstruction was the primary outcome, defined as bowel-loop diameter greater than or equal to 25 mm with abnormal peristalsis. Maximum bowel dilatation, visible peristalsis, interluminal free fluid, and bowel wall thickness were evaluated. Time to completion of imaging results was abstracted from the medical records for each imaging modality.
