Answer

In a small study by Jang et al in which the use of bedside ultrasonography by emergency physicians was compared with radiography for the detection of small-bowel obstruction (SBO), emergency physician ̶ performed ultrasonography compared favorably with radiography. Dilated bowel on ultrasonography had a sensitivity of 91% and a specificity of 84% for SBO, while radiography had a sensitivity of 46% and a specificity of 66%. [26]
