what is it and describe the procedure
Answer:
Basically, a thin wire-based camera is inserted into your rectum and large intestine. The physician examines whatever he means to examine, and then the camera is removed.
The procedure takes very little time and is completely painless -- you're under general anesthesia. I underwent it once and it was the easiest surgical procedure I've ever undergone.
This procedure is best described by a doctor, if he wants you to have it get it done
it's a procedure that takes a flexible camera tiny, and goes up into your colon via your rectum. while the procedure is taking place you should be asleep, it doesn't hurt ask your doctor to give you diprivan to put you to sleep. it's over before you know it and the doctor can tell if you have any cancer or polyps in your colon, it's a life saver and soooo easy. the only thing uncomfortable is the clean out of the bowels before you have this and that is by taking something to cause you to have many loose stools it's individualized by your doctor. so go for it and don't be afraid. it may save your life. and good luck

Colonoscopy is the minimally invasive endoscopic examination of the large colon and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus.
The first step is usually a digital rectal examination, to examine the tone of the sphincter and to determine if preparation has been adequate. The endoscope is then passed though the anus up the rectum, the colon (sigmoid, descending, transverse and ascending colon, the cecum), and ultimately the terminal ileum. The endoscope has a movable tip and multiple channels for instrumentation, air, suction and light. The bowel is occasionally insufflated with air to maximize visibility. Biopsies are frequently taken for histology.
my mother-in-law has had this done a few times as well as other fam. members. basically they stick a tube w/a camera on the end up your rear to see what's going on and take pics. sometimes (mil's case) it's b/c there's something going on that they need to check other times they just like you to have it done at a certain age just so they can keep tabs on your health. not fun-you have a restricted diet for a day or so before-mostly clear liquids and no red dye (that includes orange and purple) and they make you drink some stuff that makes you go so you clean your system out.
HAVE FUN!:)
A colonoscopy preformed in CANADA, involves pen sized tube with a scope (camera) being put up you behind and threaded into you lower bowel, usually done to find tumors (both benign and cancerous) or lesions (cuts). This procedure can be completed with both sedation and without sedation.. The sedation usually used (unless alergies are present) is Valium, Demerol, and versaid. The combination of these 3 drugs take you to a happy place. you are not put out like for surgery. You should not have any memory of the procedure being done. The bowel empting prep that you have to take the day before the procedure is the worst part of the whole procedure. The actual colonoscopy takes less that 20 minutes.
Basically, they stick a camera snake up your colon to look for polyps, diverticulitis and the early signs of colon cancer.
It is not fun, for you have to cleanse your bowels (which means to need to have an enema) and you must stop eating for at least 24 hours before the procedure.
Can you imagine the guy who does this for a living all day long?

Colonoscopy is the minimally invasive endoscopic examination of the large colon and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus. It may provide a visual diagnosis (e.g. ulceration, polyps) and grants the opportunity for biopsy or removal of suspected lesions. Virtual colonoscopy, which uses 2D and 3D imagery reconstructed from computed tomography (CT) scans or from nuclear magnetic resonance (MR) scans, is also possible, as a totally non-invasive medical test, although it is not standard and still under investigation regarding its diagnostic abilities. Furthermore, virtual colonoscopy does not allow for therapeutic maneuvers such as polyp/tumor removal or biopsy nor visualization of lesions smaller than 5 millimeters. If a growth or polyp is detected using CT colonography, a standard colonoscopy would still need to be performed. Colonoscopy can remove polyps smaller than one millimeter. Once polyps are removed, they can be studied with the aid of a microscope to determine if they are precancerous or not. Colonoscopy is similar but not the same as sigmoidoscopy. The difference between colonoscopy and sigmoidoscopy is related to which parts of the colon each can examine. Sigmoidoscopy allows doctors to view only the final two feet of the colon, while colonoscopy allows an examination of the entire colon, which measures four to five feet in length. Often a sigmoidoscopy is used as a screening procedure for a full colonoscopy.
