The objective of this article is to review the pathophysiology of acute small bowel diseases, and to correlate the mechanisms of disease with computed tomography (CT) findings. Disease entities will be classified into the following: immune mediated and infectious causes, vascular causes, mechanical causes, trauma, and others. Having an understanding of acute small bowel pathophysiology is a useful teaching tool, and can lead to imaging clues to the most likely diagnosis of acute small bowel disorders.

    ABSTRACT: Vascular disorders of the small bowel (excluding duodenum) are common pathologic entities that represent a diagnostic challenge. This is because the small bowel is the most difficult part of the gastrointestinal (GI) tract to image due to its location, length, and tortuosity. Advances in imaging and enteroscopic techniques have occurred over the past several years, but these techniques have limitations and the optimal method of assessing the small bowel remains elusive. The aim of this chapter is to provide a comprehensive overview of the etiology, clinical features, and management of small bowel vascular disorders including the selection of appropriate imaging studies and the key features that may allow the characterization of these disorders. Broadly speaking, vascular disorders of the small bowel can be divided into those causing small bowel ischemia and those causing small bowel bleeding.
