Anal and rectal disorders

Anal fissure   Anal itching
An anal fissure is a tear in the internal lining of the anus. Treatment of anal fissures is divided into medical and surgical groups. Medical treatment of acute fissures is based upon topical creams, sitz baths, perirectal hygiene and dietary changes consisting of increasing fiber content.   Anal itching is also called rectal itching. Anal itch is an irritating sensation around the anus that is relieved temporarily by scratching or rubbing. Anal itching occurs more often in men, and, most of the time, no cause can be identified. Anal itching occurs around and near the anus, which is the opening for the bowels.
Anorectal abscess   Hemorrhoids
An anorectal abscess is a collection of pus in the anal or rectal region. Symptoms include painful, hardened tissue in the perianal area, discharge of pus from the rectum, a lump or nodule, tenderness at the edge of the anus, fever, constipation, or pain associated with bowel movements. Treatment involves drainage of the abscess.   Hemorrhoids, often called piles, are clusters of veins in the anus, just under the membrane that lines the lowest part of the rectum and anus. Hemorrhoids are dilated veins which occur in and around the anus and rectum. Humans are prone to hemorrhoids because erect posture puts a lot of pressure on the veins in the anal region.
Ostomy   Pilonidal disease
An ostomy is a surgical procedure performed when normal bowel or bladder function is lost due to birth defects, disease, treatment for disease, or injury. Types of ostomy procedures include colostomy, ileostomy, and urostomy. The type performed depends on the location and extent of the disease or injury.   Pilonidal disease is a chronic skin problem found most often in the sacrococcygeal region. Pilonidal disease usually occurs in young, hairy white men but can also occur in women. Treatment for pilonidal disease can include keeping the area around the crease of the buttocks clean, draining the cyst.
Proctitis   Rectal prolapse
Proctitis is inflammation of the lining of the rectum, called the rectal mucosa. Proctitis can be short term (acute) or long term (chronic). Many diseases spread by sex may cause proctitis, such as gonorrhea, syphilis, or herpes. A rectal injury or putting objects in the rectum may cause proctitis.   Rectal prolapse is a condition in which the rectum, (the lower end of the colon, located just above the anus), turns itself inside out. Rectal prolapse is protrusion of rectal tissue through the anus to the exterior of the body. Several factors may contribute to the development of rectal prolapse.
Imperforate anus    
Imperforate anus is a congenital absence or obstruction of the anal opening. Imperforate anus is a malformation of the anorectal region that may occur in several forms. The rectum may end in a blind pouch that does not connect with the colon. A condition of stenosis (narrowing) of the anus or absence of the anus may be present.
