Diagnostic Performance of Point of Care Ultrasound to Identify Intestinal Obstruction

As reported in previous studies, Point-of-Care Ultrasound (POCUS) has good performance for the diagnosis of bowel obstruction even when compared with CT. This inexpensive, radiation-free tool is available in a majority of ED. It is performed at the patient's bedside with immediate results. The learning curve allows Emergency Physicians (EP) to perform this exam after a relative brief training period. The investigators aim to investigate the ability of POCUS performed before CT to exclude the diagnosis of bowel obstruction in patients admitted for abdominal pain.
