If a small polyp is found outside the anus, it should be surgically removed in a timely manner. Although it is a benign lesion, the repeated stimulation of the polyp after each bowel movement in the perianal area can also induce the possibility of malignant transformation of benign disease. In addition, there will be obvious foreign body sensation, local pain, and even blood in the stool, which also seriously affects the patient’s work and quality of life. The surgery is very simple, with excision under local anesthesia and nodal suturing of the wound, or local electrocautery can be performed. Although benign polyps are said to be benign, routine pathological examination should be performed after surgery. The cause of polyps is mainly due to repeated local chronic inflammatory stimulation of the perianal area. Therefore, you should pay attention to local hygiene and insist on daily cleaning sitz bath. If conditions allow, you can apply saline baths or potassium permanganate baths. Regular anoscopic examination should be performed.
