“…The cause of mechanical obstruction can be intraluminal (gallstones, vegetative tumors, or foreign bodies), intramural (stenosis generated by parietal infiltration of the tumoral process or by an inflammatory reaction, e.g., Crohn’s disease), or extraintestinal (bands, adhesions, carcinosis, retro/intraperitoneal mass). The most frequent cause of small bowel occlusion is adhesions, followed by hernias and neoplasm; in developing countries, infectious causes (such as abdominal tuberculosis) should be considered [ 5 , 6 , 7 , 8 , 9 ]. Although adhesions resulting from prior abdominal surgery are the predominant cause of SBO, accounting for 60% to 75% of cases, SBO should not be excluded in patients without any history of previous surgical procedure (‘virgin abdomen’).…”

Small bowel obstruction (SBO) is a common condition requiring urgent attention that may involve surgical treatment. Imaging is essential for the diagnosis and characterization of SBO because the clinical presentation and results of laboratory tests may be nonspecific. Ultrasound is an excellent initial imaging modality for assisting physicians in the rapid and accurate diagnosis of a variety of pathologies to expedite management. In the case of SBO diagnosis, ultrasound has an overall sensitivity of 92% (95% CI: 89–95%) and specificity of 93% (95% CI: 85–97%); the aim of this review is to examine the criteria for the diagnosis of SBO by ultrasound, which can be divided into diagnostic and staging criteria. The diagnostic criteria include the presence of dilated loops and abnormal peristalsis, while the staging criteria are represented by parietal and valvulae conniventes alterations and by the presence of free extraluminal fluid. Ultrasound has reasonably high accuracy compared to computed tomography (CT) scanning and may substantially decrease the time to diagnosis; moreover, ultrasound is also widely used in the monitoring and follow-up of patients undergoing conservative treatment, allowing the assessment of loop distension and the resumption of peristalsis.
