Resection of anal fissure or ulcer

Anal fissure is usually caused by long-term constipation, and its symptoms are mainly pain and blood in the stool, which brings great pain to patients. Prolonged anal fissures can cause children to be afraid to eat because of fear of defecation, leading to malnutrition and affecting their growth and development. If it develops into an old anal fissure, surgical treatment is still needed, and anal fissure resection or ulcer resection is generally used.
