What should you know about ulcerative colitis in rectal stump?

A rectal stump is the remaining rectum after surgery has diverted or removed part of the bowel. The lining can still become inflamed even when stool no longer passes through it. Possible symptoms include mucus or blood from the anus, pressure, urgency, pelvic discomfort or abdominal pain. Some people have little or no sensation, so a change from their usual pattern matters.

These symptoms can also arise from infection, irritation, medication effects or other bowel problems. The fact that someone has discharge or bleeding does not identify the cause on its own. Review may involve an examination, blood or stool tests, and an endoscopic assessment when the specialist considers it appropriate.

Contact the team that performed the operation or manages your ulcerative colitis if new discharge, bleeding, pelvic pain or worsening bowel symptoms appear. Describe the colour and amount of discharge, how often it occurs, associated fever and any change in pain. Do not insert medicines or products into the rectum unless prescribed.

Treatment is individual. Your specialist may discuss topical treatment, medicines for bowel inflammation, surveillance or further surgery depending on the anatomy and findings. Keep taking regular medicines unless a clinician tells you to stop, and bring your operation details and current medication list to appointments.

Seek urgent care for heavy or persistent rectal bleeding, severe or rapidly increasing abdominal or pelvic pain, fever with marked illness, repeated vomiting, fainting, or a swollen abdomen. These symptoms may signal significant inflammation, infection or another complication that needs prompt assessment.

Ask whether the discharge or bleeding fits inflammation of the stump, what examination is planned, how symptoms should be recorded, and which changes require same-day help. Ask whether you need ongoing surveillance and how your current bowel surgery affects treatment choices.
