Don’t think it’s wrong. It’s just a common conversation in colonoscopy. Who hasn’t been to the hospital several times? If you want to say that there are so many strange examinations in the hospital, colonoscopy must be on the list.
colonoscopy is an examination in the Department of Gastroenterology. It is a kind of slender and flexible medical instrument. It mainly transmits the image of intestinal mucosa to the computer processing center through the electronic camera installed at the front end of colonoscopy during the process of pushing in-depth examination, and the processed images are displayed on the screen in real time to realize the inspection function. Examination, from the anus into the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, to the appendix.
this kind of invasive inspection method will bring discomfort to people more or less. Moreover, before colonoscopy, the patient needs to take some diarrhea drugs to fully discharge the feces. Otherwise, the feces in the intestinal tract may block the camera, making doctors unable to clearly observe the condition of intestinal mucosa, which will also bring discomfort. So colonoscopy, in many people’s eyes, looks terrible.
as mentioned above, colonoscopy has a wide range. It is of great significance in helping doctors guide the diagnosis or treatment of intestinal mucosal diseases. It can help to find intestinal polyps, intestinal tumors, intestinal inflammation and other diseases, especially intestinal cancer.
colonoscopy has a high diagnostic rate for early colorectal cancer. The lancet has published a study on screening for colorectal cancer. Follow up of 170 thousand people has been followed up for 17 years. Conclusion: a flexible sigmoidoscopy can significantly reduce the incidence of colorectal cancer and reduce the incidence rate of colorectal cancer by nearly 30% in the next 17 years.
the indications of colonoscopy are very wide, not limited to the above. In general, if the colon is suspected to have lesions, priority should be given to colonoscopy. Colonoscopy is a kind of physical examination item, actually has no symptom, also can do colonoscopy. For people over 40 years old, even if they have no obvious symptoms of lower digestive tract, it is recommended to take colonoscopy regularly to achieve the purpose of physical examination. For people with family history of intestinal cancer, it is recommended to carry out regular physical examination of colonoscopy at the age of 35.
Yu Changhui, deputy chief physician of the Department of Gastroenterology, Zhujiang Hospital, Southern Medical University, said that according to the development speed of colorectal lesions, theoretically, one colonoscopy can ensure 10 years of safety. Because in most cases, it takes 10 years or even longer for high-grade neoplasia from normal mucosa to polyps, and it may take 10 years or more for polyps to develop into tumors. Therefore, under the premise of high-quality colonoscopy, if no abnormality is found in the examination, ordinary people can feel at ease for 10 years after a colonoscopy.
However, generally speaking, it is recommended to have colonoscopy reexamination within 3 to 5 years because of individual differences and some special situations. Now colonoscopy can’t detect all parts of the intestine. Some lesions in the folds of the colon, or some tiny polyps, may be missed. If the patients have related discomfort and lesions, they need to review strictly under the guidance of doctors according to their own conditions, which may be shorter time.
