An anal fistula is a small channel that can develop between the end of the bowel and the skin near the anus.
An anal fistula can cause bleeding and discharge when passing stools - and can be painful.
An anal fistula can occur after surgery to drain an anal abscess. In some cases, an anal fistula causes persistent drainage. In other cases, where the outside of the channel opening closes, the result may be recurrent anal abscesses. The only cure for an anal fistula is surgery.
An anal fissure (fissure-in-ano) is a small, oval shaped tear in skin that lines the opening of the anus. Fissures typically cause severe pain and bleeding with bowel movements. Fissures are quite common in the general population, but are often confused with other causes of pain and bleeding, such as hemorrhoids.
Piles are hemorrhoids that become inflamed. Hemorrhoids are masses, clumps, cushions of tissue in the anal canal - they are full of blood vessels, support tissue, muscle and elastic fibers.
A perirectal abscess is a collection of pus in the deep tissues surrounding the anus. By contrast a perianal abscess is a shallower collection of pus under the skin surrounding the anus; however, both are sometimes described as an anal abscess. Both types of abscesses need immediate medical attention; however, a perirectal abscess usually is the more severe infection. A delay in treatment may cause serious worsening of the condition and unnecessary complications.
Rectal prolapse is a condition in which the rectum (the lower end of the colon, located just above the anus) becomes stretched out and protrudes out of the anus. Weakness of the anal sphincter muscle is often associated with rectal prolapse at this stage, resulting in leakage of stool or mucus. While the condition occurs in both sexes, it is much more common in women than men.
Anal itching is a common condition. The itch, situated in your anus or on the skin just around your anus, is often intense and may be accompanied by a strong urge to scratch. You may find anal itching to be embarrassing and uncomfortable. Also called Pruritus Ani (proo-RIE-tus A-nie), anal itching has many causes, such as skin problems, excessive washing or hemorrhoids.
Pudendal Neuralgia is a chronic pain condition that affects the pelvic floor. Pain may occur in the genitals, perineum, and anus. Pain typically worsens throughout the day, especially with sitting. Pudendal neuralgia usually occurs with compression, rubbing, or stretching of the Pudendal nerve. A number of conditions can cause symptoms similar to those of Pudendal neuralgia, so this condition is normally diagnosed by process of elimination.
Several factors contribute to establishing a correct diagnosis of STDs of the Anorectum. Included in these are:
Colorectal cancer (also known as colon cancer, rectal cancer or bowel cancer) is the development of cancer in the colon or rectum (parts of the large intestine). It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and feeling tired all the time.
