What are the examination ranges of electronic colonoscopy

The scope of electronic colonoscopy mainly includes the colon, rectum, and ileocecal area, which can be used to diagnose lesions such as inflammation, polyps, tumors, and can also perform biopsy or therapeutic procedures.

Electronic colonoscopy can clearly observe subtle changes in the colonic mucosa, and has clear diagnostic value for inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Early colon cancer and precancerous lesions such as adenomatous polyps can be detected through endoscopy. During the examination, small polyps can be directly removed or tissue can be taken for pathological examination. For unexplained lower gastrointestinal bleeding, colonoscopy can accurately locate the bleeding point and perform hemostasis treatment. Patients with intestinal obstruction can identify the location and nature of the obstruction through colonoscopy, and in some cases, stents can be placed to alleviate symptoms. The ileocecal examination can assist in the diagnosis of special lesions such as appendiceal abscess and intestinal tuberculosis. Strict bowel preparation is required before the SEP examination to ensure clear visibility. postoperative observation should be conducted for complications such as abdominal pain and rectal bleeding, and vigorous exercise should be avoided. It is recommended to gradually transition from a liquid diet to a normal diet and avoid spicy and stimulating foods. People with long-term constipation or diarrhea should undergo regular follow-up examinations, and those with a family history of colon cancer should shorten the screening interval. If there is persistent fever or severe abdominal pain after examination, seek medical attention promptly.
