How do you rule out intussusception with ultrasound?

To confirm the diagnosis, your doctor may order: Ultrasound or other abdominal imaging.

Imaging will typically show a “bull’s-eye,” representing the intestine coiled within the intestine.

What does intussusception feel like in adults?

In adults, intussusception is usually accompanied with intermittent abdominal pain, nausea, vomiting, constipation, melena, weight loss, and fever. Abdominal pain is considered to be the most common symptom, presenting in 70-100% of cases [15].

How do you fix intussusception in adults?

Air or contrast enema: A soft tube is placed in the rectum and air or a contrast fluid, such as barium, is passed through the tube and into the intestines and bowels. This highlights blocked areas on an X-ray. In some cases, an enema helps straighten out the intestine, fixing the intussusception.

How serious is intussusception in adults?

Intussusception can cut off the blood supply to the affected portion of the intestine. If left untreated, lack of blood causes tissue of the intestinal wall to die. Tissue death can lead to a tear (perforation) in the intestinal wall, which can cause an infection of the lining of the abdominal cavity (peritonitis).

Can an ultrasound Miss intussusception?

With its high negative predictive value of 99.7%, an ultrasound exam can rule out intussusception in approximately 86% of patients but can identify the conditions that mimic it. The presence of mesenteric lymph nodes within the lumen of the intusscipiens is a highly specific ultrasound finding.

Can you poop with intussusception?
