Can intussusception be seen on ultrasound?

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 hernia cause intussusception?

These confirmed the presence of paraduodenal hernia and intussusception. Many patients with paraduodenal hernia may present incarcerated hernia, and may show risks of ischemia, gangrene and perforation in the absence of treatment options. Therefore, surgery is strongly recommended upon diagnosis.

How do you rule out intussusception with ultrasound?

To confirm the diagnosis, your doctor may order: Ultrasound or other abdominal imaging. An ultrasound, X-ray or computerized tomography (CT) scan may reveal intestinal obstruction caused by intussusception. Imaging will typically show a “bull’s-eye,” representing the intestine coiled within the intestine.

What is intussusception ultrasound?

Intussusception occurs when one segment of bowel is pulled into itself (or a neighboring loop of bowel) by peristalsis. It is an important cause of an acute abdomen in children and merits timely ultrasound examination and reduction to preclude significant sequelae including bowel necrosis.

How sensitive is ultrasound in the diagnosis of intussusception?

Ultrasound in diagnosing intussusception has an overall sensitivity: 0.98 (95% CI: 0.96-0.98), specificity: 0.97 (95% CI: 0.94-0.99), positive likelihood ratio (PLR): 38.5 (95% CI: 15.5-95.8) and negative likelihood ratio (NLR): 0.02 (95% CI: 0.02-0.04), with an area under ROC (AUROC) curve of 0.99 (95% CI: 0.98-1.00).

What is telescoping of the intestine?

Intussusception (in-tuh-suh-SEP-shun) happens when one part of the bowel slides into the next, much like the pieces of a telescope. When this “telescoping” happens: The flow of fluids and food through the bowel can get blocked. The intestine can swell and bleed.

What is the most common cause of intussusception?

The cause of most cases of intussusception in children is unknown. Though intussusception is rare in adults, most cases of adult intussusception are the result of an underlying medical condition, such as a tumor. In children, the intestines can usually be pushed back into position with a minor procedure.

When does intussusception occur?

Intussusception is most common in babies 5 to 9 months old, but older children also can have it. Boys get intussusception more often than girls.

What is the difference between volvulus and intussusception?

What is volvulus? Volvulus also causes a bowel blockage (obstruction), but it is different to intussusception in that the bowel twists around itself rather than being caught up inside itself. A loop of bowel gets wound around another part of bowel along with the tissue that surrounds it (mesentery).

What does intussusception mean?

Intussusception (in-tuh-suh-SEP-shun) is a serious condition in which part of the intestine slides into an adjacent part of the intestine. This telescoping action often blocks food or fluid from passing through.

How does intussusception happen?

What causes intussusception in adults?

In adults, intussusception is usually the result of a medical condition or procedure, including: A polyp or tumor. Scar-like tissue in the intestine (adhesions) Weight-loss surgery (gastric bypass) or other surgery on the intestinal tract.

Which ultrasound findings are characteristic of intussusception?

Children with classic findings of intussusception, however, need to be investigated with an enema, which is both diagnostic (the gold standard in the diagnosis of intussusception) and therapeutic. Ultrasound signs include: target sign (also known as the doughnut sign) pseudokidney sign. crescent in a doughnut sign.

How is intussusception diagnosed in children?

When a child is suspected of having an intussusception, the first-line modality for diagnosis is ultrasound imaging. Abdominal radiography is not recommended. 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.

Can ultrasound help diagnose abdominal wall hernias?

The use of ultrasound in the diagnosis of abdominal wall hernias Abdominal wall ultrasound is a valuable tool in the scheme of management of patients in whom the diagnosis of abdominal wall hernia is unclear.

What is intussusception in the abdomen?

Intussusception. Intussusception occurs when one segment of bowel is pulled into itself or a neighboring loop of the bowel by peristalsis. It is an important cause of an acute abdomen in children and merits timely ultrasound examination and reduction to preclude significant sequelae including bowel necrosis.
