Colonoscopy

Colonoscopy is visual examination of the lining of your colon (large intestine). Along flexible tube is passed through the rectum. Through this telescope the doctor will be able to look for any abnormalities that may be present. If necessary small tissue samples (biopsies) can be taken during the examination (painlessly) for laboratory analysis. Polyps (abnormal growths of tissue) can be removed, using an electric snare wire.

Preparation:

 To allow a clear view, the colon must be completely free of waste material.

You will be given a laxative solution to drink the day before examination and instructions to remain on clear fluids. Do not eat or drink anything after midnight. If you must take prescription medication, use only small sips of water. Avoid taking Aspirin products or Iron preparation for 5 days before the examination.

Clear Liquid Diets:

 Allowed– Fruit flavored, Water, Tea hot or iced, Lemonade/Sprite, Strained fruit juices 7up.

  Not Allowed– Milk, water melon and strawberry or other food/beverage

What Will Happen?

The Doctor and/or Nurse will explain the procedure and answer your question. Please tell them if you have had any other endoscopy examination, or any allergies or any reactions to medications. You will be asked to sign a consent form, giving your

Permission to have the procedure performed. You will be asked to put a hospital gown, and to remove your eyeglasses, contact lenses and dentures.

You will be placed comfortable on your side, and may be given medication by injection through a vein to make you sleepy and relaxed. The Doctor will pass the colonoscope

Through the anus, into the rectum and advance it through the colon. You may experience some abdominal cramping and pressure from the air which is introduced into your colon. This is normal and will pass quickly. You may be asked to change your position during the examination   and you will be assisted by Nurse. The examination takes 15-30minuts.

Afterwards:

You will remain in the unit for at least 2-4hours. A companion MUST be able to drive you home as the sedation impairs your reflexes and judgment. For the remainder of the day you MUST NOT drive a car, operate machinery or make important decision. We suggest that you rest quietly at home.

Risks:

Colonoscopy can result in complications, such as reactions to medicine and bleeding, these complications are very rare(less than 1/1000), but may require urgent treatment. The risks are slightly higher when colonoscopy is used to apply treatment, such as removal of polyps. Be sure to inform us if there is any pain, black tarry stools or persistent bleeding in the hours or day after colonoscopy.
