Colonoscopy
What is a colonoscopy?
A colonoscopy is a specialised endoscope (a flexible tube with a camera) to look inside the colon (large intestine) and the last part of the small intestine. The magnified and detailed view of the bowel that is possible through a colonoscopy is why it is an essential tool in the diagnosis of various bowel disorders and, in some cases, to perform treatments of bowel conditions such as the removal of polyps (polypectomy).
What is the importance of a colonoscopy?
Colonoscopies allow for a complete visualisation of the bowel, allowing for diagnoses that otherwise that can’t be made such as in cases of bleeding, the presence of polyps and even bowel cancer. Picking up diseases of the colon, and where appropriate, treating them, stops the progression of the condition and potentially avoiding major surgery.
When is a colonoscopy recommended?
A colonoscopy may be recommended when patients have:
- Rectal bleeding or a positive result on a Faecal Occult Blood Test (FOBT).
- Anaemia symptoms (low red blood cell count).
- Abdominal pain without any explanation or bowel habits change.
- Significant or unexplained weight loss.
- A family history of bowel cancer or polyps.
- Monitoring of patients with inflammatory bowel disease (IBD).
- Ongoing monitoring of previously treated polyps or bowel cancer.
How to prepare for a colonoscopy
Preparation aims to achieve a clean bowel which is necessary for the clear visualisation:
Dietary Restrictions: Have a clear-fluid diet (water, apple juice, clear broth, etc.) 24 hours before the procedure.
Bowel Preparation: Take the prescribed laxatives (Glycoprep or PicoPrep) according to the instructions provided to completely empty the bowel.
Details of the procedure
The colonoscopy procedure is usually conducted for about half an hour. You are kept comfortable under an anaesthetic and patients are kept under observation for 1-2 hours post the procedure before they are discharged.
Care after the procedure
You will need a driver after the procedure as sedation impacts your coordination for 24 hours. During this period, avoid using machinery, signing legal documents, or make important decisions.
Risks and complications
Colonoscopy is a procedure that is mostly safe, but as is the case with all medical procedures, it is not without risks:
- Common: Mild abdominal discomfort, nausea, or bruising at the injection site.
- Rare: Bleeding, bowel perforation, or missed abnormalities.
Why it's important to have a colonoscopy
A colonoscopy can diagnose a wide array of conditions, including polyps, and remove them if found. Polyps are pre-cancerous, and by removing them by polypectomy, the odds of developing bowel cancer in the future are significantly reduced.
