COLONOSCOPY :

Colonoscopy is an internal examination of the colon ( large intestine ) and rectum, using an instrument called a colonoscope.

PREPARATION :

  1. Exelyte solution ( 30 ml + 30 ml ) to be taken with 300ml of Limca 6 hrs before the procedure.
  2. After Exelyte drink at least 2 to 3 liters water should be taken in next 2 hrs.
  3. Don’t eat or drink anything for 3 hrs prior to colonoscopy.

PROCEDURE :

The colonoscope has a small camera attached to a flexible tube. Unlike sigmoidoscopy, which can only reach the lower third of the colon, colonoscopy examines the entire length of the colon.

You have to lie on your left side with your knees drawn up toward your chest. After you have received a sedative and pain reliever, the colonoscope is inserted through the anus. It is gently moved into the beginning of the large bowel and sometimes into the lowest part of the small intestine.

Air will be inserted through the scope to provide a better view. Suction may be used to remove fluid or stool. Because the health care provider gets a better view as the colonoscope is pulled back out, a more careful examination is done while the scope is being pulled out. Tissue samples may be taken with tiny biopsy forceps inserted through the scope. Polyps may be removed with electrocautery snares, and photographs may be taken. Specialized procedures, such as laser therapy, may also be done.

WHY COLONOSCOPY ?

Abdominal pain, changes in bowel movements, or weight loss.

  1. Abnormal changes ( such as polyps ) found on sigmoidoscopy or x-ray tests ( CT scan or barium enema ).
  2. Anemia due to low iron ( usually when no other cause has been found ).
  3. Blood in the stool, or black, tarry stools.
  4. Follow-up of a past finding, such as polyps or colon cancer.
  5. Inflammatory bowel disease ( ulcerative colitis and Crohn’s disease ).
  6. Screening for colorectal cancer.
