What's with the colonoscopy?

colonoscopy is to use a flexible fiber hose with a light source and a miniature electronic camera at the end, which is about 14CM long, and slowly enter the large intestine from the anus to check the lesions, tumors or ulceration of the large intestine. If necessary, tissue examination or polypectomy can be taken. Colonoscopy is an invasive examination, and patients will definitely feel uncomfortable, and even a few patients will have to stop the examination in the middle. Therefore, many hospitals have now implemented painless colonoscopy, and patients can be in a comfortable sleep state during the examination. After the examination, patients only need to rest for a while to leave, which also reduces the psychological pressure and fear of patients and is more conducive to doctors' examination, treatment and diagnosis. The results of colonoscopy are intuitive and accurate, which is an important basis for clinical diagnosis of intestinal diseases. Therefore, if you really need to have a colonoscopy, please don't give up eating because of choking. The current medical examination methods have become more and more humanized.
