If left untreated, patients with Crohn's disease can progress into colorectal cancer depending upon the region involved. The common complication of Crohn's disease include obstructions, abscesses, free perforation, and hemorrhage. With treatment, most people achieve a healthy life, and the mortality rate for the disease is low.

Crohn's disease increases the risk of [[cancer]] in the area of inflammation.

Crohn's cannot be cured by surgery, though surgery does happen with blockages, whether partial or a full blockage occurs.  After the first surgery, the Crohn's usually shows up at the site of the resection though it can appear in other locations.  After a resection, scar tissue builds up which causes strictures.  A stricture is when the intestines becomes too small to allow excrement to pass through easily which can lead to a blockage. After the first resection, another resection may be necessary within five years of the first surgery.  [http://ibdcrohns.about.com/od/surgeryprocedures/a/resectioncrohns.htm]

Overview

If left untreated, patients with Crohn's disease can progress into colorectal cancer depending upon the region involved. The common complication of Crohn's disease include obstructions, abscesses, free perforation, and hemorrhage. With treatment, most people achieve a healthy life, and the mortality rate for the disease is low.

Natural History

If left untreated, patients with Crohn's disease can progress into colorectal cancer depending upon the region involved. For example, individuals with Crohn's disease involving the small bowel are at higher risk for small intestinal cancer. Similarly, people with Crohn's colitis have a relative risk of 5.6 for developing colon cancer.[1] Screening for colon cancer with colonoscopy is recommended for anyone who has had Crohn's colitis for eight years, or more.[2][3][4]

Complications

Common complications of Crohn's disease include:[5]

Prognosis

  • Crohn's disease is a chronic condition for which there is currently no cure. It is characterized by periods of improvement followed by episodes when symptoms flare up.
  • With treatment, most people achieve a healthy life, and the mortality rate for the disease is low.
  • Crohn's disease is associated with an increased risk of small bowel and colorectal carcinoma.[7]
  • Many patients will have temporary stoma formations together with possible associated complications.[8]
