title: Medical management of severe inflammatory disease of the rectum and distal colon: non-nutritional aspects.
abstract: Rectal bleeding is the cardinal symptom in patients with inflammation of the rectum, and initial management must be directed at establishing an underlying diagnosis. In many patients in the Western World this will be idiopathic inflammatory bowel disease, although in all cases other causes such as infection must be excluded. Idiopathic proctitis is usually due to either ulcerative colitis or Crohn's disease, and in both conditions corticosteroids, either systemic or topical, provide the mainstay of treatment. The 5-aminosalicylic acid drugs are helpful in both acute and maintenance treatment, again given either systemically or topically, while metronidazole is of value in patients with Crohn's disease. In those with refractory proctitis alternative agents such as azathioprine, immunomodulating drugs and barrier agents may be useful. Severe inflammation of the rectum secondary to pelvic irradiation will also usually respond to topical steroid therapy, although sucralfate enemas may be equally successful; in resistant cases other treatments may be needed. Infective proctitis, when diagnosed, may require treatment with specific antimicrobial agents.
