What is the experience of colonoscopy?

Colonoscopy refers to inserting a slender flexible endoscope hose with lens into the intestinal cavity of a patient from the anus. With the help of the lens, we can clearly observe the specific lesions of the whole large intestine cavity, such as rectum, sigmoid colon, descending colon, transverse colon, ascending colon, cecum, etc. When the lesions are found, we can take out suspicious intestinal tissue for pathological examination.

Therefore, colonoscopy is called the gold standard for the diagnosis of colorectal cancer.

During colonoscopy, in order to make the endoscope enter the intestinal cavity smoothly, the medical staff will inflate the patient's intestine from time to time; At the same time, it can obtain a more ideal and clearer view of the intestine, which is convenient for better observation of the intestinal cavity; In the initial inflation process, patients will feel abdominal distension, but under the guidance of medical staff, abdominal distension will gradually adapt.

In addition, because people's intestines are "nine bends and eighteen bends", when the mirror shines in the corner, the pain will be accompanied by bloating (everyone's intestines are different, so the pain will vary from person to person, not to say that everyone has similar feelings).

Colonoscopy is aimed at the large intestine of human body, and the abdominal distension and pain produced during examination can be tolerated by most people. Except for some patients with poor tolerance, ordinary patients can choose ordinary colonoscopy for examination.

The examination of small intestine usually adopts colonoscopy, which can be entered from oral cavity or anus, and the examination method is similar to colonoscopy; However, because the length of the small intestine accounts for four-fifths of the whole intestine, it needs to hover in the abdominal cavity several times during colonoscopy, and the pain caused by it is unbearable for ordinary people. Therefore, painless enteroscopy or capsule endoscopy can be used to examine the small intestine.
