In general, a foreign body sensation can be felt in the anus, and the anal papilla can be prolapsed out of the anus during defecation. The large papilla can be pushed back into the anus by hand, which can cause anal edema and swelling if not reset in time, and the small papilla can return to the anus by itself. The enlarged papillae can cause irritating anal gland secretion, which can cause anal itching and wetness. Local examination: the enlarged anal papillae can be palpated, and small anal papillae can be seen under the speculum as triangular protrusions, while large anal papillae are like soy or grape-like elevations, hard, smooth, with a large head and small tip, which can be prolapsed outside the anus. The surface is covered with skin and is gray or yellowish white. How to treat anal papilloma The treatment of papillary fibroma, mainly surgery, can achieve the purpose of radical treatment. Although anal papilloma is a benign tumor, anal papilloma is generally considered to have a tendency to become malignant and should be treated surgically. The specific treatment methods are: 1. Non-surgical treatment of anal papilloma: Non-surgical treatment is still the main treatment method for some patients with mild symptoms. (1) sitz bath method: hot water sitz bath 1-2 times a day, local hot compress, improve blood circulation to promote the absorption of inflammation. (2) 10% silver nitrate solution, or 1 to 3% gentian violet solution, applied to the nipple, can be cured. (3) Hemorrhoid cream or bolus nano-anal, 1 to 2 times a day, can reduce the symptoms. 2.Surgical treatment of anal papilloma (1)Excision and ligation of anal papilloma: (2)Electrocautery: routine anesthesia in the anus, expose the anal papilloma under anoscope, press the high frequency electrocautery probe on the root of the tumor, turn on the power, and cauterize the papilloma completely.
