Colonoscopy Preparation

WHAT IS A COLONOSCOPY?

A colonoscopy is a diagnostic procedure, which allows us to look at the lining of your large intestine. It is accomplished by using a colonscope, which is a long thin tube, which is flexible and has a light on the end. If an abnormality is seen then both a picture and biopsy can be taken. Polyps (an abnormal growth of colonic tissue) when found can be removed through the instrument. In order to minimize any discomfort you might experience during the examination, you will receive intravenous medications immediately prior to the procedure (please notify us of any known drug allergies or previous problems with anesthesia). The duration of the procedure varies, ranging from ½ to 1-½ hours.

APPOINTMENT DATE AND TIME - please arrive at least 15 minutes before your appointment.

NOTHING TO EAT OR DRINK THE DAY OF THE PROCEDURE. IF YOU HAVE ANY QUESTIONS PLEASE CALL THE OFFICE.


Preparation begins the day prior to the exam. Because the colonoscopy involves looking inside the large intestine, your colon must be thoroughly cleansed.


  • YOU MUST HAVE SOMEONE TO DRIVE YOU HOME. A CAB IS NOT ACCEPTABLE. THE PERSON MUST BE RESPONSIBLE FOR YOU WHILE THE SEDATION WEARS OFF.
  • ASPIRIN CONTAINING PRODUCTS MUST BE AVOIDED 10 DAYS PRIOR TO THE PROCEDURE.
  • AVOIDING CORN FOR 10 DAYS IS BENEFICIAL.
  • IF YOU ARE TAKING COUMADIN, YOU MUST NOTIFY OUR OFFICE.

This “small volume” prep is not meant for any patient who has had kidney failure or kidney problems. If this applies, please call for our alternate prep.


DAY BEFORE THE EXAMINATION

  • A regular breakfast before 10:00 is permitted.
  • Lunch and dinner should consist of clear liquids (see below).
  • At 7:00 p.m. add 1.5 ounces of Fleets Phospho Soda to one half glass of water and drink. This can be followed by clear fruit juice.
  • CLEAR LIQUIDS ALLOWED: WATER, FRUIT JUICE (APPLE,WHITE GRAPE) CHICKEN BOUILLON BROTH, JELLO(AVOID RED JELLO) LEMON ICES, GINGER ALE. NO SOLID FOODS, MILK OR MILK PRODUCTS OR COFFEE.

  • PLEASE DO NOT DRINK ANY ADDITIONAL FLUID AFTER MIDNIGHT EXCEPT FOR THE PREP AT 5:00AM. IF YOU EAT OR DRINK ANYTHING ADDITIONAL, THE PROCEDURE CANNOT BE PERFORMED


WHAT TO EXPECT DURING THE PROCEDURE?

The procedure is usually well tolerated. There may be some discomfort during the colonoscopy, but it is usually mild.


WHAT TO EXPECT AFTER THE PROCEDURE?

  • You might be sleepy for an hour or two after the procedure due to the sedation you will receive at the time of the examination.
  • You will expel gas post procedure as this was passed into the colon during your colonoscopy. This was done solely for visualization purposes.
  • If a polyp is removed, then further instructions may be given to you.
  • Unless you are instructed otherwise, you will be able to resume your regular diet afterwards.
  • Rarely it is necessary to admit a patient after the procedure.


ARE THERE ANY COMPLICATIONS FROM COLONOSCOPY AND POLYPECTOMY?

Colonoscopy and polypectomy are safe and are associated with very low risk when performed by physicians who have been specially trained and are experienced in these endoscopic procedures.

One possible complication is perforation, in which a tear through the wall of the colon may allow leakage of intestinal fluids. This complication usually requires surgery, but may be managed conservatively in selected cases.

Bleeding may occur from the site of biopsy or polyp removal. This is why avoidance of aspirin products is so important. It is also important to tell the doctor of any previous dental or surgical procedures. Bleeding is usually minor, and often stops on its own, or can be controlled with cauterization through the colonoscope. Rarely blood transfusions or surgery may be required.

Localization irritation of the vein may occur at the site of medication injection. A tender lump may develop. This lump could remain for several weeks to several months, but it goes away eventually. Other risks include drug reactions and complications from unrelated diseases, such s heart attack or stroke.
