Colonoscopy Consent ๐ฉ
๐ Procedure
- Colonoscopy โ visual inspection of the entire colon using a flexible camera inserted via the rectum.
๐ก Indications
- Investigation of rectal bleeding, anaemia, or change in bowel habit
- Colorectal cancer screening or surveillance in high-risk patients
- Biopsy of lesions or removal of polyps
๐งพ Procedure Walkthrough
- Performed under sedation ยฑ analgesia. Patient lies on left side.
- Patient must follow a strict bowel preparation the day before the procedure to ensure clear views โ this may involve laxatives and a special diet.
- A flexible camera is inserted via the rectum to visualise the entire colon.
- COโ 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.
โ ๏ธ Risks & Complications
- 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
๐ฌ Common Patient Questions
- Will it hurt? โ Some cramping or bloating is expected, but sedation is given for comfort.
- Will I be asleep? โ Most are drowsy but awake; general anaesthesia is not usually required.
- Can I go home after? โ Yes, but you must not drive for 24 hours post sedation.
- Will I be able to eat? โ Resume normal diet after recovery unless told otherwise.
โ Benefits
- Direct visualisation of colon
- Ability to biopsy suspicious areas or remove polyps immediately
- Prevention or early detection of colorectal cancer
๐ Alternatives
- CT colonography (less sensitive for small polyps)
- Flexible sigmoidoscopy (views only part of colon)
- No investigation โ not recommended in most cases due to risk of missed serious pathology
๐ง Special Considerations
- Ensure anticoagulation status reviewed โ 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
