The information provided here will help you to prepare for endoscopy. This information must be reviewed with your doctor prior to surgery, at which point you will be asked to sign the consent form confirming that you understand this information prior to the doctor proceeding.
Prior to the procedure you will be assessed by a qualified anaesthetist. You will be given intravenous sedation (via an injection) by the anaesthetist who will monitor you throughout the procedure. The anaesthetist will ensure that you are asleep and comfortable throughout.
What is the colonoscopy procedure?
The colonoscope is a thin flexible tube, about the thickness of a finger for examination of the large bowel. After you have been given intravenous sedation the tube is inserted gently and moved inside the large bowel up to the junction with (and sometimes into) the small bowel. In about 5% of patients only part of the bowel can be inspected due to variation in the structure of the bowel or technical difficulty. Several procedures can be carried out through the colonoscope including taking small tissue samples (biopsy) and removal of polyps.
Polyps of the large bowel may become cancerous; therefore it is advised that if any polyps are found they should be removed at the time of examination to prevent risk of cancer. At the time of examination you will be sedated and it is therefore not possible to discuss the removal of the polyp with you. If you have any reservation regarding removal of a polyp you must discuss this matter before the colonoscopy with the doctor.
What is the gastroscopy procedure?
The gastroscope is a thin flexible tube, smaller than the thickness of a finger for examination of the oesophagus and stomach. After you have been given intravenous sedation the tube is inserted through your mouth and into the stomach. Several procedures can be carried out through the gastroscope including taking small tissue samples (biopsy).
How can you help before your colonoscopy?
Although colonoscopy is the best way of assessing abnormalities of the large bowel there is still a small chance that abnormalities are not seen, especially when the preparation is poor. Before the procedure, the bowel will need to be emptied to allow proper examination. If the bowel is not adequately emptied the procedure may have to be abandoned and repeated at a later stage. Therefore it is essential that you follow the instructions carefully to empty the bowel. These instructions will be clearly explained to you when you pick up your bowel preparation kit from the Waverley Endoscopy office.
You will need to arrange a friend or relative to drop you off and to pick you up after your procedure as you will be unable to drive yourself.
What you should tell us before your gastroscopy/colonoscopy
Please inform either the medical or nursing staff if you are sensitive (allergic) to any drugs or substances. You must notify the doctor if you have been taking blood thinning tablets (warfarin or coumadin) or are taking any form of aspirin (this also includes plavix or iscover). If you have any doubt about the medication that you are taking, please discuss this with your doctor before the procedure. In addition, if you have heart valve disease or a pacemaker, this must be brought to the attention of the doctor.
