Ultrasound of Small Bowel Obstruction: A Pictorial Review

Abstract: 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% C… Show more

“…[30] The roles of POCUS in clinical practice and its accuracy in the evaluation of IO have been well described in the literature. [13,22,31] In this paper, we summarized the diagnostic criteria of ultrasound for SBO and CO, pertaining to the morphological and functional characteristics of bowels. Having clear criteria would help further in making systematic and accurate clinical judgments.…”

“…Fluids, especially if poor in cells, appear as black, hypoechoic to anechoic in US, because most of the US’ beam goes through them and only a small part of the waves is reflected and returns to the transducer. The search for black fluid and its possible shades of gray is the basic principle of our POCUS protocol [ 3 , 4 , 7 ]. This US approach is versatile and a valuable tool for physicians involved in emergency settings and also suitable for physicians without extensive training or background in clinical sonography [ 8 ].…”
