Anal blockage is most common in perianal hemorrhoids these diseases, especially internal hemorrhoids, stage III and IV internal hemorrhoids will repeatedly prolapse the mucosa of internal hemorrhoids, and in severe cases will manifest as prolapse or even inability to return. In this case, the patient will show significant perianal pain and discomfort, blockage, and even difficulty in defecation. For recurrent hemorrhoids you should opt for surgical treatment, which is easier to deal with in the early stages and can be done by applying an anastomosis and choosing local excision of the hemorrhoidal mucosa or circumferential excision, paying attention to avoiding collateral damage during surgery. If severe internal hemorrhoids are secondary to prolapse, you can also inject sclerosing agents in the submucosa to promote local adhesions or choose open rectal fixation surgery, both of which can alleviate the patient’s symptoms to some extent. After surgery it is also important to adjust the diet, actively treat constipation and eat a reasonable diet.
