Ischemic disease of the small and large bowel

Ari Grinspan, Asher Kornbluth

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Acute mesenteric ischemia (AMI) and colonic ischemia (CI) are two very different disease processes with very different management strategies. AMI typically occurs with a proximal occlusion of the superior mesenteric artery or one of its branches, while CI arises from insufficient blood flow to the distal capillaries in watershed areas of the colon. Incidence of CI is significantly higher than AMI. AMI classically presents with pain out of proportion to examination in a susceptible patient. Early diagnosis is essential, as ischemia can quickly develop into intestinal infarction leading to remarkably high mortality rates. CI typically presents with crampy abdominal pain associated with bright red blood per rectum and commonly has a benign course.
