Utilization of ultrasound for the evaluation of small bowel obstruction: A systematic review and meta-analysis

The existing literature suggests that ultrasound is a valuable tool in the diagnosis of SBO with a sensitivity and specificity comparable to that of CT. Ultrasound may save time and radiation exposure, while also allowing for serial examinations of patients to assess for resolution of the SBO. It may be particularly valuable in settings with limited or no access to CT. Future studies should include more studies in the Emergency Department setting, comparison of probe choices, and inclusion of more pediatric patients.
