K60: Fissure and fistula of anal and rectal regions

K60.2: Anal fissure, unspecified

The anus is located at the end of the intestines and is ring-shaped. A sphincter muscle in the last segment of the intestines ensures that we only intentionally excrete feces through the anus.

The skin on the anus may tear for instance because of an inflammation or if you strain heavily during a bowel movement. The fissure on the anus can cause pain, especially during and after a bowel movement. Because of the pain, you generally try to avoid a bowel movement. That can cause constipation. There can also be weeping or bleeding from the fissure on the anus. The fissure may cause the anus to itch.
