Volvulus is when part of the large intestine twists on itself and the mesentery. Mesentery is tissue that holds the intestines to the abdomen wall. The twisted intestine cuts off the intestine’s blood supply and affects bowel function.
Volvulus can happen anywhere in the large intestine. It is most common in the lowest part near the rectum.
This condition needs to be treated right away.
The cause of volvulus is not known.
Volvulus is more common in older, inactive people and those who live in care homes. Other things that may raise the risk are:
Symptoms may be:
The doctor will ask about symptoms and past health. A physical exam will be done.
Blood tests will be done to check for problems.
Imaging will be done to see the intestines and confirm the diagnosis. Tests include:
The goal is to clear the blockage and help the bowels work again. Treatment depends on where the twisting is and if there has been damage.
Care may include:
There are no current guidelines to prevent volvulus.
