Crohn's symptoms also depend upon the extent of inflammatory damage to organs. About 30 percent of patients have inflammatory Crohn's disease, or damage to the mucosa, the first layer of the lining of the organs, and to the supporting connective tissue under it.
Others suffer a more advanced form of the disease, called fistulizing or perforating Crohn's disease. In these cases, inflammation extends through the wall of the intestines leading to intra-abdominal fistulas, or abnormal passages through which fluids, secretions, and abscesses can pass. This type of Crohn's disease, known as internal or intra-abdominal fistulizing disease, affects about 20 percent of people with the disease. It does not include fistulas involving the anus, rectum and perineal region (region surrounding the anus and including the genitals).
Perineal or perianal disease (known as "Perianal Crohn's disease") occurs in about one third of patients and can become disabling if not treated aggressively. These include swelling of the anal sphincter or development of fissures and ulcers in the sphincter, causing bleeding and pain with defecation. Perirectal abscesses can cause fever, pain, or pus in the anal area. If fistulas have developed, mucus or pus may drain from openings into the skin surrounding the anus. Patients with perianal Crohn's disease frequently need surgical drainage of the abscesses and fistulas that form. Perianal Crohn's disease can involve the vagina. Fistulas from the rectum can let air and often stool pass through the vagina. This complication almost always requires surgery.
The third type of Crohn's is called stenosing or stricturing Crohn's disease. About 50 percent of patients with Crohn's disease affecting the lower portion of the small intestine follow this route. Early in the course of the disease, patients develop thickening, stiffening, and scarring. The narrowing of the small bowel may eventually result in a small bowel obstruction. The symptoms of obstruction are severe painful cramping, vomiting, nausea, and abdominal distention. As a consequence of chronic narrowing of the small intestine, fistulas or perforations of the bowel wall may develop. Most patients with stenosing Crohn's disease will require surgery, usually 7 to 10 years after the onset of Crohn's disease.
