Gastro Oesophageal Reflux Disease :: Colonoscopy :: Polypectomy
Colonoscopy is a procedure used to view large intestine (colon and rectum) using an instrument called colonoscope (a flexible tube with a small camera and lens attached). The procedure can detect inflamed tissue, ulcers, and abnormal growths. It is used to diagnose early signs of colorectal cancer, bowel disorders, abdominal pain, muscle spasms, inflamed tissue, ulcers, anal bleeding, and non-dietary weight loss.
The procedure is done under sedation. The colonoscope is inserted into the rectum which gently moves up through the colon until it reaches the cecum (junction of small and large intestine). Colonoscopy provides an instant diagnosis of many conditions of the colon and is more sensitive than X-ray.
The colonoscope is then withdrawn very slowly as the camera shows pictures of the colon and rectum onto a large screen. Polyps or growths can also be removed by colonoscopy which can be sent later for detection of cancer.
Instructions for colonoscopy
Your physician may provide you written instructions and also will be communicate verbally on how to get prepared for the colonoscopy procedure. The process is called bowel prep.
Gastrointestinal (GI) tract should be devoid of solid food; a strict liquid diet should be followed for 1 to 3 days before the procedure. Patients should not drink beverages containing red or purple dye. Liquids that can be taken before surgery include fruit juices, plain coffee, tea, and water.
Certain medications such as aspirin, ibuprofen, naproxen or other blood thinning medications, iron containing preparation should be stopped before the test. Iron medications produce a dark black stool, and this makes the view inside the bowel less clear.
The day before colonoscopy you are quite to undertake bowel preparation to cleanse the colon. This consists of 2 sachets of Picolax and 2 sachets of Colonlytely. (Please refer to link to Instructions for colonoscopy). This is to eliminate any residue in the colon. The success of your examination depends on the bowel being as clear as possible; otherwise the examination may need to be repeated
Driving is not permitted for 24 hours after colonoscopy.
