Hemorrhoids generally do not require anal dilation for surgery, but a few patients do. Hemorrhoids are the most common anorectal disease, mainly due to congestion and enlargement of the veins of the anal canal or the lower end of the rectum, which can be manifested as blood in the stool, anal itching and prolapse of hemorrhoids and other symptoms. For patients suffering from hemorrhoids, their general surgery does not need to dilate the anus, but a few patients need to dilate the anus. The majority of patients do not require anal dilation, while patients with circumferential mixed hemorrhoids may require anal dilation. If they do not dilate the anus, it may lead to narrowing of the rectum and anus, which may lead to symptoms such as constipation or even intestinal obstruction. If a relatively large number of hemorrhoids are removed, anal dilatation can be used to prevent anal stenosis and thus reduce postoperative complications. If you encounter the above problems, it is recommended to go to a regular hospital in time, consult with a professional doctor, and choose the appropriate method of treatment according to the doctor’s advice.
