Extra-anal polyps usually do not go away on their own. An extra-anal polyp is a benign condition that occurs outside the anus and is considered to be a type of hemorrhoid that is asymptomatic and quiescent. Extra-anal polyps are new organisms that occur on the mucosa of the anal canal or rectum, most of which are round or oval masses with tips that can protrude into the intestinal lumen and move up and down. There are many causes of extra-anal polyps, such as polyps caused by dietary factors, polyps caused by genetic factors, and polyps caused by inflammatory irritation. The main symptom of extra-anal polyps is blood in the stool, which is characterized by blood in the stool. Extra-anal polyps usually need to be removed surgically, followed by more bed rest to avoid complications such as bleeding. The diet should also pay more attention, fasting for more than six hours a day after surgery, two days after surgery into a liquid diet, usually a semi-liquid diet, a week after surgery can resume normal diet.
