Solitary Rectal Ulcer Syndrome

Solitary rectal ulcer syndrome (SRUS) is a chronic (long-term), noncancerous condition where sores form inside your rectum. Your rectum connects your colon (large intestine) to your anus (butthole). Stool passes through your rectum and your anus when you have a bowel movement (poop).

But the name “solitary rectal ulcer syndrome” is misleading. For example, if you have SRUS, you may have a single (“solitary”) ulcer, or you may have more than one. Also, the sores aren’t always ulcers or even only in your rectum. They may be inflamed tissue or located in the part of your colon above your rectum.

There’s still a lot that researchers are learning about SRUS, including causes and the most effective treatments.

How common is solitary rectal ulcer syndrome?

Solitary rectal ulcer syndrome is rare. It occurs in about 1 out of every 100,000 people. Most people who get this diagnosis are in their 30s or 40s, but it also affects children and older adults.

Are rectal ulcers serious?

Although the ulcers can be uncomfortable, they’re usually not serious. The condition that’s causing a rectal ulcer can be serious, though. This is why you should see your provider to receive a diagnosis if you’re experiencing symptoms of solitary rectal ulcer syndrome.
