It will normally only go as far as the first part of the colon, this is known as the caecum. The colonoscope tube is thin and flexible and ranges from 125 centimetres (48 inches) to 183 centimetres (72 inches) in length.
A colonoscopy is a procedure that lets your health care provider check the inside of your entire colon (large intestine). The procedure is done using a long, flexible tube called a colonoscope.
Colonoscopy (koh-luh-NAH-skuh-pee) lets the physician look inside your entire large intestine, from the lowest part, the rectum, all the way up through the colon to the lower end of the small intestine.
During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon.
For the procedure, you'll lie on a table while the doctor inserts a colonoscope through your anus and into your rectum and colon. The scope inflates your large intestine with air for a better view. The camera sends a video image to a monitor, allowing the doctor to examine your large intestine.
Loops or angulation in the colon are possibly the most common patient-related source of difficulty. Some bends require additional skill to navigate. Loops, particularly in the sigmoid colon, can result in loss of control of the endoscope as well as patient discomfort.
While an endoscopy focuses on the upper gastrointestinal (GI) tract—including the esophagus, stomach, and first part of the small intestine (duodenum)—a colonoscopy specifically targets the lower GI tract, particularly the large intestine and rectum.
As the doctor will need to see the lining of the colon, the bowels must be empty for the procedure to be successful. One of the main preparations for a colonoscopy involves drinking a special liquid or taking other oral laxatives that induce diarrhea and empty the bowels.
How can you tell if your colon is clean and ready for a colonoscopy? Your stool after finishing your bowel prep agent can act as a guide. Your stool should be clear, yellow, light and liquid. The presence of dark particles or thick brown or black stool means you are not ready for colonoscopy.
How long does it take a colonoscopy prep to clear bowels completely? It can take 12 to 16 hours for the bowels to completely clear. Eating a low-residue, soft diet for a day or more before starting the prep can help make it easier and faster.
No, a colonoscopy can't detect IBS, a condition also known as irritable bowel syndrome.
If your colonoscopy results list a positive finding, this means your doctor spotted a polyp or other abnormality in the colon. This is very common, and not a reason to panic. Most polyps are harmless, and your doctor probably removed it during the colonoscopy. Some polyps, however, can be cancerous or precancerous.
After a colonoscopy, minor complications including abdominal discomfort, bloating, nausea, diarrhea, and constipation can occur.
After the test, you may be bloated or have gas pains. You may need to pass gas. If a biopsy was done or a polyp was removed, you may have streaks of blood in your stool (feces) for a few days. Problems such as heavy rectal bleeding may not occur until several weeks after the test.
With the increasing role of endoscopic and intraluminal therapies and surgery, the surgeon/endoscopist will often employ the use of snare techniques to remove intra-colonic pathology. Although an uncommon complication, the snare can become jammed or stuck and unable to be removed by conventional maneuvers.
What if I've taken all my preparation and am still passing solid stool on the day of my exam? In this case, your procedure will need to be rescheduled. You may be prescribed a different preparation for your next procedure. Please call the triage nurse to reschedule your procedure with a different preparation.
The biggest culprits that will show up in a colonoscopy and obscure our view are foods like nuts, seeds and high-fiber cereals. You also want to avoid granola, coconut, dried fruit and fresh fruit with the skin on, like apples and pears, or fruit with seeds, like strawberries and raspberries.
“If you do get nauseous from the prep, it may be because you drank it too fast. Moving around can also help reduce nausea. If you are prone to nausea, your provider may also be able to give you medication to reduce it,” Dr. Kedrin says.
