Bowel preparation instructions
Before Procedure
Please follow the instructions for bowel preparation as given in the leaflet dispensed by the pharmacist. Good bowel prep response is important for a successful procedure with adequate views of the bowel lining.

If taking iron tablets, anticoagulants and diabetic medications, these need to be stopped or doses modified as appropriate.

This is a day case procedure, on arrival to hospital, nursing team would check the details and do baseline observations.
Consent form would be signed for the procedure and if there are any further questions it could be discussed.

Procedure

The colonoscopy procedure usually takes around 30 to 45 minutes.

Observations including pulse and BP would be checked and throughout the procedure, the pulse oximeter probe will be placed on the finger. Additional oxygen will be given through the nasal cannula.

A sedative and a painkiller will be given through the vein to help relax and be comfortable during the procedure. 

At the start of the procedure you will lie on your left-hand side and a cold lubricating jelly would be applied to examine the back passage. The colonoscope (flexible tube with camera at the tip) would be then inserted through the back passage.

To view the lining of the colon the bowel lumen is expanded slightly with air which would cause mild discomfort and distention of the abdomen. The tip of the colonoscope passes through curves and bends in the colon and it can cause mild discomfort. This discomfort is minimised by changing positions and if needed additional sedative/analgesia would be given.

As part of this procedure biopsies may be taken and if feasible polyps would be removed. Polyps (small cauliflower/broccoli like growths) are usually benign (not cancerous), but they can change into cancer over time.  The samples will be sent to a laboratory for testing to see if the cells are benign or malignant (cancerous).​
Recovery
After the procedure, you will be taken to your room/recovery bay and nurses would do another set of observations. Refreshment drink/snacks would be provided when awake.  

The recovery process would be for less than a hour. If there are no symptoms apart from mild abdominal distention/dicomfort (due to the air insufflation as part of the procedure) you can go home. 

Follow up appointment in clinic would be usually organised after the procedure, to explain the endoscopy and biopsy results.
Risks
This is a safe procedure however like with any other procedure there are some risks of complications.

The main risks are bleeding, perforation (small tear in the lining of bowel) and sedation related complications including aspiration pneumonia. The risk of bleeding and perforation increases if there is a need to do polypectomy.

If there is excessive bleeding through the back passage or increased severity of abdominal pain, please seek assistance, which could include A&E visit.

The procedure is done carefully and safely to avoid these risks.
