Ulcerative colitis is a superficial inflammation of the large intestine, not caused by bacteria, which results in ulceration and bleeding. The patient typically experiences alternating periods with no or few symptoms, and periods with frequent stomach pains and diarrhoea that is mixed with pus, blood, and mucus. It’s rare in the UK, with one new case per 10000 people per year. Currently, there are 100000 patients with ulcerative colitis and usually they are diagnosed between the ages of 15 and 30-years-old. Rarely are people of Asian origin affected, and women are 30 per cent more likely to suffer than men. What causes ulcerative colitis? The exact cause of ulcerative colitis is unknown. Hereditary, infectious and immunological factors have been proposed as possible causes. What are the symptoms of ulcerative colitis? The symptoms of ulcerative colitis can vary considerably. The disease is characterised by periods with diarrhoea, mixed with pus, blood, and mucus, which alternate with periods of few or no symptoms. When the colitis is active, the patient often has mild stomach pains, and sometimes a fever. The symptoms vary according to the extent of the disease. A quarter of patients only have the disease in the rectum, which means that the symptoms are fairly mild. In one third of patients, the disease also affects the lower part of the large intestine. In the remaining patients, ulcerative colitis affects all of the large intestine. How can ulcerative colitis be

Colon cancer and cancer of the rectum usually begin as a small polyp. While most colon polyps are benign, some do become cancerous. Colon cancer symptoms may include a change in bowel habits or bleeding, but usually colon cancer strikes without symptoms. That’s why it’s important to get a colon cancer screening test, such as a colonoscopy. If the cancer is found early, the doctor can use surgery, radiation, and/or chemotherapy for effective treatment. •Many people survive colon and rectal cancer. Histologically, adenomas are classified in three groups: tubular, tubulovillous, and villous adenomas. K-ras mutations and microsatellite instability have been identified in hyperplastic polyps. Therefore, hyperplastic polyps may also have malignant potential in varying degrees. Bleeding is the most common symptom of rectal cancer, occurring in 60% of patients. Bleeding often is attributed to other causes (eg, hemorrhoids), especially if the patient has a history of other rectal problems. Profuse bleeding and anemia are rare. Bleeding may be accompanied by the passage of mucus, which warrants further investigation. Change in bowel habits is present in 43% of patients; change is not evident in some cases because the capacity of a rectal reservoir can mask the presence of small lesions. When change does occur it is often in the form of diarrhea, particularly if the tumor has a large villous component. These patients may have hypokalemia, as shown in laboratory studies. Some

This clip demonstrates a normal colonoscopy and starts in the terminal ileum where the delicate villous architecture is well seen. The colonoscope is withdrawn into cecum. Here at the base of the cecum is the orifice of the appendix. In the tissue surrounding the appendiceal orifice, a speckled pattern of lymphoid aggregates can often be seen. During the colonoscopy, the endoscopist both insufflates the lumen of the colon with air and aspirates the small amount of liquid that remains from the preparation previously taken by the patient to cleanse the colon. The liquid often has a slightly yellowish tinge of bile. Backing out of the cecum, a better view of the ileocecal valve is obtained. It has a rounded slightly yellowish appearance. Traveling down the colon, a repeating pattern of pouches and folds are seen. These pouches are called haustra and the folds are referred to as the plicae semilunares or simply the semilunar folds. A word about the colonic tissue itself. The white dots seen throughout the exam are reflections of the colonoscope’s light off the tissues and back into the viewing lens. Normally the tissue has this glistening pink hue. Also visible is the delicate vascular plexus of capillaries that nurture the colonic mucosa. Here in the sigmoid colon, the earliest signs of diverticulosis are visible. These are outpouchings of the mucosa through the muscular layers of the colon and are seen commonly starting in the fifth decade of life. More dramatic examples

What is a colonoscopy? A colonoscopy allows a doctor to look inside the entire large intestine.The procedure enables the physician to see things such as inflamed tissue, abnormal growths, and ulcers. It is most often used to look for early signs of cancer in the colon and rectum. It is also used to look for causes of unexplained changes in bowel habits and to evaluate symptoms like abdominal pain, rectal bleeding,and weight loss. The colon, or large bowel, is the last portion of your digestive tract, or gastrointestinal tract.
