On April 27th, Red Net Time (correspondent Li Shu), colonoscopy is a diagnostic method used by doctors to check the lesions in the large intestine and colon. In recent years, with the popularization of painless colonoscopy, the pain of colonoscopy has been greatly reduced, patients can easily complete colonoscopy, and people are no longer afraid of colonoscopy as in the past. Electronic colonoscopy can clearly display some images of the patient's lesions on the computer screen, which is small in diameter and can be inserted from the anus into the intestine. The lens can be used for multi-angle and multi-directional examination and treatment, and can be tracked randomly, which is convenient for comparison, inquiry and consultation of lesions.

So, what kind of symptoms should colonoscopy check? Li Hui, deputy chief physician of the Department of Gastroenterology, Changsha Dongda Anorectal Hospital, said that colonoscopy plays a decisive role in the diagnosis and treatment of inflammatory diseases such as colorectal polyps, ulcerative colitis, chronic colitis, and malignant transformation of colon. Therefore, colonoscopy is needed in the following situations:

1, stool bleeding

Stool bleeding, if only once or twice occasionally, and the blood is bright red liquid, may be caused by anal fissure, hemorrhoids and so on. However, if the color of stool bleeding is dark red and occasionally caked, it means that the blood comes from the intestine, and colonoscopy should be considered at this time.

2. Long-term diarrhea or changes in defecation habits

People with chronic diarrhea or changed defecation habits suddenly have chronic diarrhea or constipation if they have not had constipation or diarrhea before. Or generally defecate in the morning, and defecation habits suddenly change. At this time, colonoscopy is needed to find out the specific reasons.

3, chronic abdominal pain, unexplained emaciation

Intestinal inflammation and tumors can cause chronic abdominal pain. When patients have long-term abdominal pain accompanied by emaciation and other symptoms, they should be alert to the occurrence of malignant tumors and go to the hospital for examination and treatment in time to avoid delaying their illness.

4, abdominal mass

There is an unknown mass in the abdomen that can be felt. At this time, colonoscopy should also be considered, because it is likely to be caused by intestinal polyps or intestinal malignant transformation.

5. People with family history of intestinal cancer or over 40 years old.

People with a family history of colorectal cancer or adenoma should be highly vigilant and need to have colonoscopy regularly. With the increase of age, the prevalence of colorectal cancer will also increase, so it is recommended that people over 40 years old have a colonoscopy every year.

Changsha Dongda Anorectal Hospital reminds that colonoscopy can observe the internal situation of colon and large intestine, which plays a very important role in the diagnosis of digestive tract diseases. Therefore, when there are symptoms such as long-term diarrhea or change of stool habits, bloody stool, unexplained fatigue, anemia, emaciation, etc., you should go to a regular hospital in time to receive colonoscopy, clarify the cause and treat the symptoms.
