How to treat chronic anal fissure

Treatments for chronic anal fissure include medication, lifestyle adjustments, and surgery. The specific choice depends on the severity of the condition.

1. Drug treatment

Drug treatment is a common method for chronic anal fissures, mainly by relieving pain, promoting healing and improving bowel movements. Nitroglycerin ointment applied to the affected area can relax the anal sphincter and improve local blood circulation. Local anesthetics such as lidocaine gel can relieve pain. Oral laxatives such as lactulose can soften stools and reduce irritation during defecation.

2. Lifestyle Adjustment

Improving lifestyle habits is crucial to the recovery of chronic anal fissures. Increasing dietary fiber intake, such as eating more vegetables, fruits and whole grains, can prevent constipation. Maintaining a daily water intake of 1500-2000 ml helps soften stools. Avoid sitting or standing for long periods of time, and perform proper anal lifting exercises to strengthen the muscles around the anus.

3. Surgical treatment

For chronic anal fissures that are not responsive to medication, surgical treatment is a necessary option. Internal sphincterotomy relieves spasms and pain by cutting off part of the internal anal sphincter. Anal fissure resection directly removes the diseased tissue and promotes the growth of fresh tissue. Laser therapy uses laser energy to promote tissue repair, with minimal trauma and rapid recovery.

The treatment of chronic anal fissure requires a combination of medication, lifestyle and surgical methods. Early intervention can effectively prevent the condition from worsening. Patients should choose a suitable treatment plan based on the doctor's advice and pay attention to daily care to promote healing and prevent recurrence.
