The colonoscopy can be repeated once every one to two years after the removal of a simple intestinal polyp, and once every six months in the case of multiple intestinal polyps or malignant findings on examination. Most of the intestinal polyps are single, and in most cases, benign polyps are common. Therefore, when the simple intestinal polyp resection, if the test result suggests benign, can be 1~2 years to review the colonoscopy, to avoid polyp reoccurrence and missed detection; if the test result is malignant, should be at least six months to review the colonoscopy. For intestinal polyps, there are some multiple intestinal polyps, in addition, in most cases, there is a malignant situation, so after surgical resection needs to be based on the results of further treatment, and if the results of the test for malignant, need to be rechecked once every half a year, part of the cases need to be rechecked for a shorter time interval. Intestinal polyp resection review colonoscopy time, in most cases is based on the results of the test and the doctor’s guidance, so we recommend that patients follow the doctor’s instructions, do not be careless.
