Malignant neoplasm of the colorectum - Crohn's disease Factor
Crohn's disease is an inflammatory disease of the bowel. It may also be called regional enteritis, granulomatous ileitis or ileocolitis. Diagnosis is by barium enema X-ray, sigmoidoscopy, and biopsy. Treatment may include drug therapy [often corticosteroids] or surgery. Significant medical attention would have been needed at some time although possibly not until symptoms had been present for some time.
Signs and symptoms
- Major symptoms are fever, abdominal pain, diarrhoea, often without blood, and generalised fatigability. There may be associated weight loss. Rectal bleeding is distinctly less common than with ulcerative colitis. There may be associated severe anorectal complications such as fistulas, fissures, and perirectal abscess. These features may appear before the onset of symptoms.
- Typically, the disease has its onset in a young adult male with a history of fatigue, variable weight loss, right lower quadrant discomfort or pain, and diarrhoea. Low grade fever, anorexia, nausea and vomiting may also be present.

3720 the veteran has established the causal connection between the Crohn's disease of the colorectum and operational service for the clinical onset of malignant neoplasm of the colorectum.
Clinical onset and operational service [3720]
32254 the veteran was suffering from Crohn's disease of the colorectum for at least five years before the clinical onset of malignant neoplasm of the colorectum.
3722 the Crohn's disease is causally related to operational service.
Clinical onset and eligible service [3721]
32255 the veteran was suffering from Crohn's disease of the colorectum for at least ten years before the clinical onset of malignant neoplasm of the colorectum.
3723 the Crohn's disease is causally related to eligible service.
