The causes of anal fissure include infection, trauma, mental factors, anatomical factors and anal canal stenosis. Medical treatment or surgical treatment can usually be taken to relieve clinical symptoms.

1, the cause of anal fissure

(1) infection factors: if there is anal sinusitis, it will lead to local infection, because anal sinusitis occurs on the sawtooth line and then belongs to the anal canal. Due to inflammatory stimulation, it can cause local ulcers of anal canal and anal fissure.

(2) Traumatic factors: If constipation occurs, because the stool is relatively dry, it is easy to break the anus during defecation and form anal fissure.

(3) Mental factors: If you are in a state of excessive mental stress for a long time, it will cause anal pressure to increase, muscle tension, and induce anal fissure.

(4) Anatomical factors: Because the anorectal ligament is hard and has poor elasticity, it is usually easy to spread and form anal fissure when stool is dry.

(5) Anal canal stenosis: If the patient has congenital anal canal stenosis, anal fissure can be slowly formed during defecation.

2. Treatment of anal fissure

(1) Drug therapy: If you take Maren Pills, Changweishu Capsules and other drugs orally according to the doctor's advice, you can improve constipation and keep your stool unobstructed. At the same time, local application of erythromycin ointment is beneficial to the recovery of the disease. In addition, lidocaine gel can be applied locally according to your own situation to relieve pain.

(2) Surgical treatment: If the symptoms of anal fissure are serious or the drug treatment effect is not good, you can choose surgical treatment according to your own situation. Commonly used surgical methods include anal dilatation, anal fissure scratch line, anal fissure resection, sphincterotomy, etc.
