It can be so painful that patients are unwilling to have a bowel movement, leading to constipation and fecal impaction. Bleeding, itching and foul-smelling discharge are other symptoms that may occur. Pain following bowel movements is the most common symptom of anal fissures. Anal fissures can occur as a result of HIV, anal cancer, and tumors in rare cases. Inflammatory bowel disease, constipation, and straining are some common symptoms. Anal fissures can be associated with any number of non-traumatic conditions and should be suspected when they appear in unusual locations. Causes of Anal Fissures:Īnal Fissures are mostly caused by trauma. A hairless, glandless, extremely sensitive anoderm spreads the entire length of the anal canal until it meets the dentate line that separates the rectum from the anal canal. Within the anus (the anal verge or groove), the skin (dermis) of the inner buttocks changes into an anoderm.Īnoderm does not have hair, sweat glands, or sebaceous (oil) glands, and it contains an increased number of sensory nerves that can detect light touch and pain. They cause pain during bowel movements that are often severe.Īnal fissures occur in specialized tissue called anoderm that lines the anus and canal. They cause rectal bleeding in infants.įissures are a common condition in the anus and anal canal and are responsible for 6% – 15% of the visits to a colon or rectal surgeon. People of all ages and gender are affected by fissures. This is usually a tear or cut occurring in the anus (the opening that allows stool to exit the body) that extends upward into the anal canal. Anal fissures are common in people with constipation and are typically not a severe condition but an annoying experience.
