Colonoscopy Doctors in Jordan

Colonoscopy is an examination in which a thin, flexible tube carrying a camera and light is passed through the anus so the inner surface of the rectum and the whole colon, up to its junction with the small intestine, can be displayed on a screen. It is usually performed under intravenous sedation, and most patients recall little or nothing of the examination. The strength of the technique is that it can look and act at the same time: taking biopsies, removing polyps, stopping bleeding and dilating a narrowing. Its greatest value is preventive rather than purely diagnostic. Most colorectal cancers begin as a small benign polyp that changes slowly over years, and removing those polyps during the examination prevents them from turning into cancer later. Colonoscopy therefore does not only detect disease, it eliminates the risk arising from those particular polyps. The type and number of polyps found determine when the next examination is due, which is why the interval is never left to personal judgement. Some warning signs must not be managed with a laxative or an ointment and must not wait: rectal bleeding or blood in the stool, unexplained weight loss, a persistent change in bowel habit such as new diarrhoea, new constipation or narrowing of the stool, and iron-deficiency anaemia with no clear cause, along with new persistent abdominal pain or a close family history of colorectal cancer. Any of these warrants prompt review by a gastroenterologist. Two beliefs deserve correcting. The first is that colonoscopy is extremely painful; in reality intravenous sedation makes it tolerable for the great majority, and what patients usually report is bloating afterwards rather than pain during. The second is that normal blood tests mean no colonoscopy is needed; in reality blood tests, stool tests and ultrasound cannot see a polyp, an ulcer or an early tumour, and all of them can be normal while a significant polyp is present. Only endoscopy can see, biopsy and remove. The limits are equally clear. Colonoscopy does not examine the stomach or oesophagus, which require a separate upper endoscopy, it sees only the very beginning of the small bowel, and it does not treat irritable bowel syndrome or functional bloating. A normal result is not permanent immunity and does not exclude functional causes of symptoms. Finally, the quality of bowel preparation is the single biggest determinant of the examination's value, and an unclean colon may mean repeating it entirely. Suitability and timing are decided by clinical assessment.
