Proctitis is inflammation of the lining
of the rectum, called the rectal mucosa. Proctitis can be short term (acute)
or long term (chronic). Proctitis has many causes. It may be a side effect
of medical treatments like radiation therapy or antibiotics. Diseases
like ulcerative colitis, Crohn's disease, and sexually transmitted diseases
may also cause proctitis. Other causes include rectal injury, bacterial
infection, allergies, and malfunction of the nerves in the rectum.
Symptoms include constipation, a feeling of rectal fullness,
left-sided abdominal pain, passage of mucus through the rectum, rectal
bleeding, and anorectal pain.
Physicians diagnose proctitis by looking inside the rectum
with a proctoscope or a sigmoidoscope. A tiny piece of tissue from the
rectum may be removed and tested for a bacterium, fungus, or virus.
Treatment depends on the cause of proctitis. For example,
the physician may prescribe antibiotics for proctitis caused by bacterial
infection. If the inflammation is caused by Crohn's disease or ulcerative
colitis, the physician may recommend the drug 5-aminosalicyclic acid (5ASA),
or corticosteroids applied directly to the area or taken in pill form.
Additional Information on Proctitis
The National Digestive Diseases Information Clearinghouse collects resource
information on digestive diseases for the Combined Health Information
Database (CHID). CHID is a database produced by health-related agencies
of the Federal Government. The CHID database located on the World Wide
Web at http://chid.nih.gov/simple/simple.php, provides titles, abstracts,
and availability information for health information and health education
resources. See the results of our CHID research on
