Regular re-examination: after complete recovery, regular annual re-examination is also needed to determine whether the polyps are accompanied by recurrence, especially for adenomatous polyps, which are found to recur and need to be further resected. After the resection of intestinal polyps need to be re-examined, mainly to prevent the lesion control is not timely on the physical condition of the serious impact of the need for standardized treatment under the guidance of clinicians.
