Minor anal fissures are best treated conservatively with medication. Minor anal fissures indicate that the fissures have occurred for a relatively short period of time, the fissures are relatively fresh, and the local fissures are relatively small, so the fissures can be healed by using medication. Commonly used drugs include laxatives, fissure healing drugs and pain relief drugs, as follows: first, laxatives: for example, lactulose, which can keep the patient’s bowels open and prevent constipation and dry stools from aggravating the fissure; second, fissure healing drugs: including various types of hemorrhoid suppositories, hemorrhoid cream and moist burn cream; third, pain relief drugs Third, drugs to relieve pain: such as lidocaine gel and other surface anesthetic drugs can effectively relieve the painful symptoms of anal fissure.
