    Ulcerative Colitis
    Ulcerative colitis is an inflammatory bowel disease (IBD) in which the lining of the large intestine (colon or bowel) and the rectum become inflamed. This inflammation produces tiny sores or ulcers on the lining of the colon. It usually begins in the rectum and spreads upward. It rarely affects the small intestine beyond the lower portion.

    The inflammation causes the bowel to move bowel contents rapidly and empty frequently. As cells on the surface of the lining of the bowel die, ulcers (open sores) form. The ulcers may cause bleeding and discharge of mucus and pus.

    This disease affects people of all ages. Symptoms tend to develop when people are between the ages of 15 and 30, or between the ages of 50 and 70.

    What Causes Ulcerative Colitis?
    The cause of this condition is not known. Researchers no longer believe that it is caused by stress. Today, research focuses on the immune system and heredity for possible causes.

    Who Is at Risk for Ulcerative Colitis?
    Most people with ulcerative colitis don’t have a family history of the condition. However, you are more likely to develop it if a close family member also has the condition.

    Ulcerative colitis can develop in a person of any race, but it is more common in Caucasians. If you are an Ashkenazi Jew, you have a greater chance of developing the condition than most other groups.

    Some studies show a possible link between the use of the drug isotretinoin (Accutane, Amnesteem, Claravis, or Sotret) and ulcerative colitis. Isotretinoin is used to treat cystic acne.

    Treatment of Ulcerative Colitis
    Ulcerative colitis is a chronic condition. Treatment usually involves drug therapy or surgery. The goal of treatment is to reduce the inflammation that causes your symptoms.

    Your doctor may prescribe an anti-inflammatory medication. These include sulfasalazine (Azulfidine), mesalamine (Asacol and Lialda), balsalazide (Colazal), and olsalazine (Dipentum). Reducing inflammation will help with abdominal cramps and diarrhea. More serious cases may need corticosteroids, antibiotics, or medication to suppress immune function.

    If your symptoms are severe, you will need to be hospitalized to correct the effects of dehydration and malnutrition that diarrhea causes.

    Only about 25 to 40 percent of people with this condition will need surgery to remove their colon. Surgery is performed because of massive bleeding, chronic debilitating symptoms, perforation of your colon, or if there is a risk of cancer. A barium enema and a colonoscopy can detect these serious problems.

    Surgical options include proctocolectomy with ileostomy (the most common surgical treatment) and ileoanal anastomosis.
    roctocolectomy with ileostomy involves the removal of the entire colon and rectum. A small opening is made in the abdominal wall through which the tip of the lower small intestine (the ileum) is brought to the skin’s surface. Waste will drain through the opening into a bag.

    In ileoanal anastomosis, the diseased part of the colon is removed but the outer muscles of the rectum are spared. The ileum is attached inside the rectum and a small pouch formed. After this surgery, an individual is able to pass feces through the rectum. Bowel movements will be more frequent and watery than normal.

    Complications of Ulcerative Colitis
    Ulcerative colitis increases your risk of colon cancer. Your doctor will do a colonoscopy and check for cancer when you’re first diagnosed. It is important to schedule a follow-up screening eight to 12 months after you’re diagnosed with ulcerative colitis. This helps lower your risk of colon cancer. Repeat screenings every one to two years are needed thereafter. Follow-up screenings can detect precancerous cells early.

    Long-Term Outlook for Ulcerative Colitis
    There is no known cure for ulcerative colitis. If you have this condition, you will need to be monitored by your doctor and carefully follow your treatment plan throughout your life.

    Scripted Voiceover
    This is a colonoscopy in a 75-year old man who presented for mild anemia and positive fecal blood tests. He had long-term therapy with diclofenac for arthritis affecting the large joints. This is the look in the cecum and here, we see this large ulcer that involves most of the ileocecal valve. The terminal ileum is completely normal. Lets have a closer look at the ulcer. It is well circumscribed and surrounded by completely normal mucosa. Virtual chromoendoscopy with FICE reveals no suspicious microvessels within the ulcer ground. The presentation of this ulcer is non-specific, but the appearance and the history of NSAID intake are highly suggestive of an NSAID colopathy with an ulcer. In deed the majority of mucosal changes are found in the right colon. Although histology is nonspecific we should always sample multiple biopsies to exclude other conditions as malignancy, ischemia or vasculitis.

    What is colitis?
    Just like some people get arthritis which is an inflammation of the joints, it is also possible to get inflammation of the colon. Inflammation of the colon (large intestine) is called colitis. Germs can cause colitis. Poor blood supply can cause colitis. Some medications can cause colitis. In most cases, the cause of colitis is unknown; however, colitis is not infectious and cannot be passed from one person to another like the flu or a common cold.
    When no other cause can be found for the inflammation, it falls into either one of two forms of inflammatory bowel disease – ulcerative colitis or Crohn's disease.

    What is Crohn's disease?
    Crohn's disease involves the entire thickness of the wall of the colon, and can also involve other parts of the intestines such as the small intestine. Since Crohn's disease can involve the entire thickness of the intestine, sometimes long ulcers are seen in the colon lining. These ulcers look as if someone had pulled a grass rake across the lining of the colon. They are called rake ulcers or bear claw ulcers. Crohn's disease can be patchy. It can be present in one part of the colon, absent in another, and then present in the next part.
    In children, Crohn's disease slows growth and may delay sexual development.
