Solitary rectal ulcer syndrome is a condition that occurs when one or more open sores (ulcers) develop in the rectum. The rectum is a muscular tube connected to the end of your colon. Stool passes through the rectum on its way out of the body.
Solitary rectal ulcer syndrome is a rare and poorly understood disorder that often occurs in people with chronic constipation. Solitary rectal ulcer syndrome can cause rectal bleeding and straining during bowel movements. Despite the name, sometimes more than one rectal ulcer occurs in solitary rectal ulcer syndrome.
Solitary rectal ulcer syndrome may improve with simple lifestyle strategies, such as changing your diet and drinking more fluids. In severe cases, however, surgery may be needed.
Signs and symptoms of solitary rectal ulcer syndrome include:
- Constipation
- Rectal bleeding
- Straining during bowel movements
- Pain or a feeling of fullness in your pelvis
- A feeling of incomplete passing of stool
- Passing mucus from your rectum
- Fecal incontinence
- Rectal pain
However, some people with solitary rectal ulcer syndrome may experience no symptoms.
It's not always clear what causes solitary rectal ulcer syndrome. Doctors believe stress or injury to the rectum may cause rectal ulcers to form.
Among the things that could injure the rectum are:
- Constipation or impacted stool
- Straining during bowel movements
- Rectal prolapse, which occurs when the rectum protrudes from the anus
- Uncoordinated tightening of the pelvic floor muscles that slows blood flow to the rectum
- Attempts to manually remove impacted stool
- Intussusception, which occurs when one part of the intestine slides inside another part
