So, what should we do if we have an anal fissure? Generally, for patients with early-stage anal fissures where the fissure is still fresh and without complications such as sentinel piles, hypertrophied anal papillae, anal papillitis, anal stenosis, subcutaneous fistulae, or subcutaneous abscesses, conservative treatment under medical supervision can be pursued. First, altering the diet by increasing water intake and consuming more vegetables and fruits can improve the characteristics of the stool. Post bowel movement, traditional Chinese herbal remedies for pain relief, such as Shen Tang, or sitz baths using potassium permanganate solution can be used. Locally, applications like Longzhu Ointment or Jiuhua Ointment may be applied. If constipation is present, stool softeners should be used to aid bowel movements. In the chronic stage, if symptoms are only accompanied by internal sphincter spasm and no other complications such as sentinel piles or hypertrophied anal papillae, in addition to the general treatments mentioned above, anal dilation can be considered. If dilation is ineffective, then surgical treatment should be considered at this time. For patients with chronic anal fissures who also have symptoms like sentinel piles, hypertrophied anal papillae, anal stenosis, or for those who have had prolonged ineffective treatment of initial anal fissures, it is advisable to seek surgical treatment at a hospital.
