Small bowel obstruction (SBO) is a common presentation to the emergency department (ED) and represents 15% of hospital admissions for acute abdominal complaints. Plain radiography, although traditionally recommended as the initial diagnostic imaging modality of choice, has a sensitivity of only 59% to 77%. When clinical and radiographic assessment is indeterminate, computed tomography (CT) becomes the test of choice due to its superior resolution and increased ability to identify both obstruction and its aetiology Aim: this is a prospective study in a sample of patients presenting to the emergency department (ED) with abdominal pain, vomiting, or other symptoms suggestive of a SBO (history of previous surgeries, constipation, abnormal bowel sounds, and abdominal distention). Patients will be evaluated with US prior to x-ray and CT, with possible diagnostic confirms by endoscopy or surgery.

Moreover, which clue, if any, such as anaemia, CRP, NLR, hypotension, could reinforce the need of US intestinal study.
According to the emergency referral protocols, patients that are assessed at the triage phase as likely to have any abdominal acute disease, including bowel occlusion, are preliminary studied by laboratory concurrently with the record of vital signs (blood pressure, electrocardiogram, pulse oxymetry). These information will be available during the actual visit of the Abdominal ultrasound in emergency may show fluid effusion, hemorrhagic or not, liver and/or gallbladder disease, spleen disease - possible leakage -, vascular disease (such as aneurism), inflammatory disease (Appendicitis, diverticulitis, Crohn's disease), masses and nodes (tumors, parasitic, others) and bowel occlusion . Clues, (anaemia, increased C-Reactive Protein, electrolyte abnormalities, clinical symptoms, hypotension) may reinforce the opportunity of US intestinal study, according also to the concordance with the subsequent confirmatory procedures.

definition of prevalence of US detected obstruction in patients referred to an emergency facilities with symptoms potentially suggestive for such diagnosis. Moreover, which clue, if any, could reinforce the need of US intestinal study, such as anaemia, CRP, NLR, hypotension. This information is not yet available elsewhere. Moreover, in this context, sensitivity and specificity of ultrasound vs. confirm by CT and other procedures will make more sense and will be consequently assessed.
