Overview
Brief Summary
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.
Detailed Description
Bowel obstruction (BO) is frequently suspected in the Emergency Department (ED). Computed Tomography (CT) is commonly used to diagnose this disease. However, CT is not always available in real-time, requires technician times, is associated with increased cost and exposes patients to radiations. The researchers will investigate the diagnosis performances of POCUS for the diagnosis of BO with comparison with CT which will be considered as the gold standard. The wain objective will be the ability to exclude the diagnosis of BO, the main criteria being the negative predictive value. The secondary objectives will be the diagnosis performances (sensitivity, specificity, positive predictive value), duration and difficulty of POCUS
