A colonoscopy cannot cut out internal hemorrhoids. Treatment under colonoscopy does not include hemorrhoids. Enteroscopy is a long, thin, bendable medical instrument that can enter the rectum and colon through the anus, thus observing the internal condition of the rectum and colon, and checking for congestion, redness, swelling, erosion, ulcers, polyps, tumors, etc., in the intestinal mucosal tissues. The treatment under colonoscopy can remove polyps or tumors, etc. in the rectum and colon area, but not hemorrhoids. After a patient develops internal hemorrhoids, if there is bulging hemorrhoidal tissue or blood in the stool, he or she can be observed using colonoscopy, but it is not possible to remove them directly. Moreover, internal hemorrhoids are close to the anus, and the colonoscope cannot be operated. Therefore, after the appearance of internal hemorrhoids, it is still recommended to use adhesive ring ligation treatment to block the blood flow of the entire internal hemorrhoids, so that the hemorrhoids part of the necrosis, shedding, and then achieve the purpose of healing. Alternatively, surgical treatments such as hemorrhoidectomy and cricothyrotomy can also be considered. Therefore, it is recommended that patients with internal hemorrhoids follow the doctor’s advice to choose the appropriate treatment plan according to their condition.
