If an anal fissure fails to heal on its own, surgery may be required. For large fissures that are unable to heal, the area may need to be fully removed or covered by other surrounding tissue.
Fissure surgery will effectively help to heal more serious anal fissures. Anal fissures can continuously cause burning sensations, uncomfortable itching, and bleeding. If left untreated for prolonged periods of time, harmful infections and even cancer may arise.
