Imaging in Acute Intestinal Obstruction

Acute intestinal obstruction is a common cause of morbidity in patients who present with an acute abdomen and accounts for 20% of admissions for “surgical abdomen.” Imaging is important in confirming the diagnosis and identifying the underlying cause. Safe and effective management depend on prompt and accurate diagnosis. Bowel obstruction is subdivided into small and large bowel obstruction, based on the site of luminal narrowing. The causative factors for the two subgroups are usually quite different.
