Intestinal polyps with smooth surface and clear vascular texture are a description of microscopic polyps in colonoscopy, and most of the corresponding conditions suggest benign lesions. When an intestinal polyp is detected through colonoscopy without bleeding or ulceration on the surface of the polyp, and blood vessels can be observed on the surface, it is described as a diagnostic condition, which means that it is just a simple protrusion of the tissue, and there is no localized mucosal damage or ulceration, which is highly suggestive of benign lesions. Further diagnosis can be made by clamping part of the tissue or by direct excision of all polyps for pathologic biopsy. After determining the specific condition, then do the standardized treatment. Simple small polyps, the pathology results are only benign lesions, need to be observed regularly; found malignant lesions, need to be further enlarged resection. It is recommended that patients should consult the doctor in time if they feel sick, and should not be negligent, and need to be standardized under the guidance of the clinician to avoid delaying the condition.
