Proctitis
Definition
Proctitis is an inflammation of the rectum that causes discomfort, bleeding, and occasionally, a discharge of mucus or pus.
Alternative Names
Inflammation - rectum; Rectal inflammation
Causes
There are many causes of proctitis, but they can be grouped in the following categories:
- Autoimmune disease
- Harmful substances
- Non-sexually transmitted infection
- Sexually transmitted disease (STD)
Proctitis caused by STD is common among those who engage in anal intercourse. STDs that can cause proctitis include gonorrhea, herpes, chlamydia, and lymphogranuloma venereum.
Non-sexually transmitted infections causing proctitis are seen less often than STD proctitis. The classical example of non-sexually transmitted infection occurs in children and is caused by the same bacteria that cause strep throat.
Autoimmune proctitis is associated with diseases such as ulcerative colitis or Crohn's disease.
Proctitis may also be caused by certain medications, radiotherapy, and inserting harmful substances into the rectum.
Risk factors include:
- Autoimmune disorders
- High-risk sexual practices such as anal sex
Symptoms
- Bloody stools
- Constipation
- Rectal bleeding
- Rectal discharge, pus
- Rectal pain or discomfort
- Tenesmus (pain with bowel movement)
Exams and Tests
- Examination of stool sample
- Proctoscopy
- Rectal culture
- Sigmoidoscopy
Treatment
Successful treatment of the underlying cause usually cures the problem. Proctitis caused by infection is treated with antibiotics.
Corticosteroids or mesalamine suppositories may relieve symptoms of some patients.
Outlook (Prognosis)
The probable outcome is good with treatment.
Possible Complications
When to Contact a Medical Professional
Call for an appointment with your health care provider if you have symptoms of proctitis.
Prevention
Safer sex behaviors may prevent the disease from being spread during sexual activity.
