hemorrhoids zinc oxide,Long pain is not as good as short pain, colonoscopy can not be saved

    With the westernization of modern lifestyles, including eating habits, colorectal diseases, which were originally common diseases in Europe and the United States, have shown a significant increase in incidence in China in recent years. Including various benign diseases and tumors of the large intestine. Especially in economically developed coastal areas such as Shanghai, this trend has become more obvious. The incidence of colorectal cancer in Shanghai is increasing by 4.2% every year. This phenomenon deserves the vigilance of the general public. Compared with Japan and South Korea, more than 80% of colorectal cancer diagnosed in China are in the middle and late stages, while 80% in Japan and South Korea are early cases. Compared with other digestive system tumors such as stomach, liver, gallbladder and pancreas, the effect of colorectal tumor treatment is much better, but if it is found late, the effect of radical surgery will be greatly reduced. More importantly, most colorectal cancers originate from the malignant transformation of colorectal polyps, which is the result of years of accumulation. Therefore, if the polyp is removed very early under colonoscopy, it will be killed in the "cradle". But it must be understood that smaller intestinal polyps can only be found and treated through colonoscopy. Compared with many expensive examinations such as CT, MRI, PET-CT, etc., low-cost colonoscopy is irreplaceable. Regrettably, many of our patients are afraid of colonoscopy and have poor compliance with doctors’ recommendations, believing that they magnify the pain caused by colonoscopy. Don't say that colonoscopy is not so "painful" at all. Even if it is a little sad, it is of great significance to disease prevention and treatment. The so-called "long pain is not as good as short pain" is this truth. You know, the detection probability of small colorectal polyps in the population is still quite high. Therefore, it is estimated that it is imperative for people above the middle age to include colonoscopy as a routine physical examination in the future. This is where the successful experience of Japan and South Korea lies.

    At present, electronic colonoscopy can be performed under the following conditions without contraindications:

    1. Unexplained lower gastrointestinal bleeding.

    2. Chronic diarrhea of ​​unknown cause.

    3. Abdominal masses of unknown cause cannot be excluded from lesions of the large intestine and terminal ileum.

    4. Unexplained middle and lower abdominal pain.

    5. Suspected benign or malignant colon tumors who cannot be diagnosed by X-ray examination.

    6. Suspected chronic intestinal inflammatory disease.

    7. Barium enema or intestinal examination found to be abnormal, and the nature and scope of the disease should be further clarified.

    8. Determine the scope of lesions before colon cancer surgery, and follow-up after colon cancer and polyps surgery.

    9. Unexplained low intestinal obstruction.

    10. Unexplained anemia and weight loss.

    11. Certain gastrointestinal tumors of unknown cause are abnormally elevated in serum markers, such as CEA, CA199, etc.

    12. Those who have a clear family history of colorectal cancer, that is, their immediate family members have suffered from the disease.

    13. Those who have recently experienced unexplainable changes in stool habit or stool characteristics.

    14. Before surgical treatment of hemorrhoids.

    At present, colonoscopy is not as painful as people thought in the past, and most people can accept it.

    In addition: The patient can also request a painless colonoscopy under general anesthesia. When you sleep, the colonoscopy is already done, but the risk of general anesthesia must be considered.

    Contraindications of electronic colonoscopy: Endoscopy should not be performed when the anorectal stenosis and the endoscope cannot be inserted. Patients with symptoms of peritoneal irritation, such as intestinal perforation, peritonitis, etc., are contraindicated to do this examination. In the acute stage of anorectal infection or painful lesions, such as anal fissures, perianal abscesses, etc., avoid colonoscopy. Women's menstrual period should not be checked, and should be done with caution during pregnancy. Elderly patients with body failure, severe hypertension, anemia, coronary heart disease, and cardiopulmonary insufficiency should not undergo endoscopy. In the early period after abdominal and pelvic surgery, if there is suspected perforation, intestinal fistula or extensive abdominal adhesion, this examination is contraindicated.
