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.

Conditions

Bowel Obstruction

Keywords

Bowel obstruction; Computed tomography; Ultrasound

Outcome Measures

Primary Outcomes (1)

• Negative predictive value of POCUS

  Negative predictive value of POCUS for the diagnosis of bowel obstruction compared with computed tomography result

  Through ED stay, up to 24 hours

Secondary Outcomes (3)

• Positive predictive value of POCUS for the diagnosis of bowel obstruction

  Through ED stay, up to 24 hours

• Sensitivity of POCUS for the diagnosis of bowel obstruction

  Through ED stay, up to 24 hours

• Specificity of POCUS for the diagnosis of bowel obstruction

  Through ED stay, up to 24 hours

Interventions

Point-of-Care Ultrasound OTHER

Patients admitted to the ED with abdominal pain and suspicion of bowel obstruction : realization of a Point-of-Care Ultrasound after clinical exam by the Emergency Physician in charge as a standard of care. Beside usual findings, the investigators will search for signs of bowel obstruction: dilated and incompressible small bowel loop, back-and-forth peristalsis sign. Determination of probability of small bowel obstruction. Realization of a computed tomography in search of small bowel obstruction.
