For patients suffering from hemorrhoids, after surgery, not all patients need to carry out anal expansion treatment, only patients with anal stenosis need to carry out anal expansion treatment, anal expansion treatment should be 14 days after surgery, because hemorrhoids postoperative safety period is generally 14 days, so it is recommended to carry out anal expansion treatment after 3 weeks, and the most safe after 4 weeks. Anal dilation treatment should not be too frequent, 3 to 4 times per week is preferred. As there are differences in the age of the patients and the size of the trauma, the number of dilation treatments varies and you should ask your medical professional.
