A colonoscopy is a semi-invasive procedure where a doctor visually examines a patient’s colon and removes cells for biopsy. It is used to detect gastrointestinal problems and is recommended annually for patients over 50 as a screening for colorectal cancer. The patient must prepare by following specific instructions, and the procedure is performed under general anesthesia or sedation. Post-procedure care is provided, and most patients don’t report serious complications.
A colonoscopy is a semi-invasive procedure done under general anesthesia or sedation, in which a doctor visually examines a patient’s colon and, if necessary, removes cells for biopsy. A doctor may order a colonoscopy if a patient has gastrointestinal problems or symptoms. In addition, many doctors recommend an annual colonoscopy for patients over the age of 50 as a screening for colorectal cancer.
Typically, a gastroenterologist or doctor who specializes in the gastrointestinal system performs a colonoscopy. The procedure itself involves a special scope, which is carried through the rectum and into the colon or large intestine. The images collected by the oscilloscope are transmitted to a screen, allowing the doctor to detect any abnormalities that indicate a disease or disorder. Common problems detected by colonoscopy include irritable bowel syndrome and inflammatory bowel disease or ulcerative colitis.
A colonoscopy is performed in a clinical setting on an outpatient basis. The patient must prepare for a colonoscopy by following a specific set of directions provided in advance by their doctor. Preparing for a colonoscopy involves cleaning your bowel to optimize visualization. Most patients are advised to eat a clear liquid diet for 24 hours prior to the scheduled procedure and to take some form of laxative in the scheduled doses. Physicians strongly emphasize that you follow the preparation instructions carefully, as failure to do so may cause inaccurate results or failure of the entire procedure.
When a patient arrives for a colonoscopy, they are provided with a hospital gown and an IV. The IV lead will be used for both general anesthesia and twilight sedation. Different doctors use different forms of anesthesia, but both are effective for relieving apprehension and preventing pain or discomfort during the procedure.
The whole procedure from start to finish usually takes just a couple of hours. Even though a colonoscopy is an outpatient procedure, the patient will need to be transported home afterwards due to the anesthesia. Post-procedure care will be provided by the facility, and most people will be back to their normal diet within twelve hours of the colonoscopy. Most patients don’t report any serious complications after a colonoscopy, but you should see your doctor right away if you do have any problems.
