Colonoscopy

The following information aims to assist you in preparing you for your colonoscopy procedure, provides helpful hints as you are taking your bowel preparation, briefly provides what to expect when you go home and when to seek medical help.

Preparation for colonoscopy

Bowel preparation

For a successful colonoscopy it is important the bowel is very empty. An empty bowel
means the doctor is more likely to see the lining of the bowel and detect any problems.
Poor preparation may mean the procedure will need to be repeated on another day.


Carer

It is important to arrange to have a ‘Carer’ to care for you when you leave
hospital. Every patient who has a procedure performed under sedation or general
anaesthetic and is leaving hospital within the same day as their procedure needs
to be handed over to a carer (over 18 years of age). This person will be responsible
for your wellbeing and recovery for up to 12 or 24 hours depending on the type
of anaesthesia received. The ‘Responsible Person’ brochure will provide more detail
regarding the expectation of responsibilities and the required time period.


Work arrangements

In preparing for your colonoscopy it is also important that you re-arrange your normal
activities and take time off for:

  • the preparation of the procedure
  • the day of the procedure
  • the day after your procedure (if instructed).

A medical certificate will be provided on discharge for yourself and the person
responsible for picking you up from hospital and caring for you at home.
If you have any questions before your procedure contact the preadmission
department on 3163 3426.


Medications and your procedure

Some medications must be stopped prior to your procedure. These instructions will be given by your doctor and listed on your bowel preparation instructions. Ensure you check and follow these instructions.


Diet preparation and bowel preparation

For the colonoscopy to be successful it is important to follow the diet and bowel
preparation instructions that are included in your ‘Bowel preparation medication’ pack.
Bowel preparation for your colonoscopy will take five (5) days. Refer to your bowel
preparation instructions to find the date of when to commence your preparation.
The following steps are a summary of the bowel preparation program:

Days 1–3: On these days you will need to eat a low fibre diet to reduce the bulky
waste in the bowel. This assists the preparation medication to empty the bowel. To
assist you with your low fibre diet plan refer to ‘Guide for selecting low fibre diet
options’ at the end of this booklet.

Day 4 (Day before your procedure): On this day you will need to have a clear
fluids diet and start your bowel preparation. To assist you with your clear fluids
diet plan, follow the ‘Guide for selecting clear fluids diet options’ at the end of this
booklet and the bowel preparation instructions ‘Day before procedure’.

Day 5 (Day of your procedure): Diet and bowel preparation continue on this
day and are outlined clearly under ‘Day of procedure’ in your bowel preparation
instructions. Depending on whether your procedure is booked as a morning
procedure or an afternoon procedure will be the guide as to which instructions you
will need to follow. Please note the time when to stop eating and drinking.

Some patients who experience constipation will also be prescribed pre-treatment
laxatives for three days prior to their procedure.

Helpful hints while going through bowel preparation

Bowel preparation

  • Use a measuring container with a one litre (1 L) mark. This will provide an accurate measure instead of an estimated measure.
  • If you find the taste of the preparation drink unpleasant or it makes you feel nauseated try the following suggestions:
    - Drink the bowel preparation through a straw. This helps reduce the amount of taste.
    - Sip fluids steadily instead of drinking large amounts quickly.
    - Suck an occasional barley sugar or butterscotch lolly between drinks.
    - Brush teeth or suck on ice cube prior to drinking the prep.
  • If you are feeling unwell or bloated try:
    - walking around
    - sipping on a warm clear fluid drink (e.g. peppermint tea).
  • Set an alarm to ensure you wake for your early morning bowel prep drink.
  • Keep a light on for safety when going to the toilet during the night.
  • Keep to the drinking timeframes set out in the bowel preparation instructions to assist with clearing your bowel appropriately.
  • To enhance the taste of the bowel preparation drink, add some cordial (diabetic cordial for diabetics). It is important to avoid blue, red, purple and green coloured cordial.
  • Drink extra clear fluids to assist in the cleansing of the bowel.
  • Keep warm.
  • You may feel more comfortable wearing a continence pad.


Keep well hydrated

During the bowel preparation it is expected you will be emptying your bowel
frequently and therefore losing fluids from your body. The following points will help
manage the fluid loss:

  • Be prepared with extra clear fluids by having a variety of options for clear fluids prepared prior to starting your bowel preparation.
  • Drinking plenty of fluids will help replace the fluids lost and can help to avoid headaches. If you develop a headache, you may take the medication you usually take for pain or a headache according to the medication instructions.

Reduce irritation

  • Apply protective cream around anal area to reduce irritation e.g. lanolin, paw-paw ointment, vaseline.
  • Wipe gently after each bowel motion.
  • Use wet wipes instead of toilet paper, disposing of them in the bin instead of flushing.
  • Use haemorrhoid cream to reduce discomfort if you have haemorrhoids.

 

What to do if the following occurs during bowel preparation

Failure to have a bowel motion

People vary in the time it takes to have a bowel motion after commencing the
bowel preparation. To help relieve any concerns about your progress the following
information will help guide you.

Day before your procedure:
If you have not had a bowel motion and you are not experiencing pain or vomiting,
continue drinking.

Day of your procedure:
If you are scheduled to arrive at hospital before 7.30 am and you have not had a
bowel motion or your bowel motions are not clear, go to the hospital as planned
and at the admission desk ask to speak with a nurse as soon as possible regarding
concerns about your bowel preparation.

If you are scheduled to arrive at hospital after 7.30 am and you have not had a bowel
motion or your bowel motions are not clear, please phone 3163 1630 and leave
a message for the endoscopy unit nurse. The endoscopy nurse is available to take
messages from 7:30 am and will provide you with further instructions.


Severe pain and vomiting

If you have severe pain or vomiting, or you are unwell and concerned about your
health, it is wise to attend your nearest emergency department or phone an
ambulance on 000 in order to be assessed by medical staff.


Planning for going home after the procedure

Before you go home, a nurse will speak with you and your carer about what to expect.
You will be given a copy of your procedure report and discharge instructions. A copy
of this report will be sent to your GP. Your procedure and results are to be discussed
at a follow up appointment with your GP (allow 7 days for pathology reports to be
available). You may receive a phone call or if you are required to attend the hospital
outpatient department for follow up, an appointment letter will be sent to you.


Important information for after your procedure

After you leave the hospital, if you have any non-urgent concerns please speak with
your GP or contact the procedure department on 3163 1630 or 3163 8324.
