There are no specific ultrasound findings associated with ileus. However, patients with ileus for more than seven days (prolonged ileus) may be evaluated with an abdominal and pelvic ultrasound to determine the underlying cause. Prolonged ileus is generally due to mechanical obstruction and an ultrasound can be done to determine the etiology, such as abscess, strangulated hernia and necrotic bowel.

• Prolonged ileus is generally due to mechanical obstruction and an ultrasound may be done to determine the etiology (abscess, perforation or malignancy).
• An ultrasound can also identify and rule out a secondary cause of ileus such as small bowel obstruction, strangulated hernia , ischemic, or necrotic bowel and pelvic abscess.
