Colonoscopy Consent 💩

🔍 Procedure

Colonoscopy – visual inspection of the entire colon using a flexible camera inserted via the rectum.

Performed under sedation ± analgesia. Patient lies on left side.
Patient must follow a strict bowel preparation the day before the procedure to ensure clear views — this may involve laxatives and a special diet.
A flexible camera is inserted via the rectum to visualise the entire colon.
CO₂ or air is insufflated to distend the colon for better visualisation.
Procedure takes ~30 minutes; biopsy or polyp removal may be performed.
Patient monitored post-procedure until safe for discharge.

Common (1 in 10): Abdominal bloating, discomfort, minor bleeding from biopsy/polyp site
Less Common (1 in 100): Incomplete procedure, sedation-related issues such as drowsiness, nausea, or breathing difficulties
Rare (1 in 1,000): Bowel perforation, heavy bleeding requiring intervention
Very Rare: Anaesthetic complications, infection

Will it hurt? — Some cramping or bloating is expected, but sedation is given for comfort.
Will I be asleep? — Most are drowsy but awake; general anaesthesia is not usually required.
Can I go home after? — Yes, but you must not drive for 24 hours post sedation.
Will I be able to eat? — Resume normal diet after recovery unless told otherwise.

CT colonography (less sensitive for small polyps)
Flexible sigmoidoscopy (views only part of colon)
No investigation – not recommended in most cases due to risk of missed serious pathology

Ensure anticoagulation status reviewed – may need to pause warfarin or DOACs
Check renal function if bowel prep or contrast is used
Assess capacity and language needs (interpreter if required)
Ensure patient understands not to drive, operate machinery, or make major decisions for 24 hours post sedation
Advise who to contact in case of bleeding, severe pain, or fever after the procedure

We are recommending a colonoscopy to investigate your symptoms. This involves inserting a flexible camera into your bowel to look for causes such as bleeding, inflammation, or growths.
The benefits include diagnosing conditions, removing polyps, or taking biopsies during the same procedure if needed.
Risks include bloating, minor bleeding, or — rarely — perforation of the bowel or a reaction to the sedation. You will be monitored closely throughout.
You will receive sedation to help you relax. After the procedure, you should not drive or make important decisions for 24 hours.
You have the right to ask questions, refuse the procedure, or withdraw consent at any time. Do you have any questions or concerns?
