Anorectal Diseases
Anorectal disease refers to ailments of the anus and/or rectum. The most common conditions include hemorrhoids, anal warts, anal fissures, anorectal abscesses and anal fistulas.
COMMON CAUSES OF ANORECTAL DISEASES
Anal Fissures :are the longitudinal ulcer in the anal canal. It may be acute or chronic. These tears can be caused by hard, dry bowel movements, diarrhea and inflammation. Symptoms include itching, pain, and bleeding.
Hemorrhoids : are the varicosities of the veins of the anal canal. It can be located inside the anus (internal hemorrhoids) or in the area surrounding the anus (external). Common causes of hemorrhoids include:Age, Pregnancy, Obesity, Straining, Lifting heavy objects, Chronic diarrhea, Chronic constipation
Symptoms include pain, inflammation, and itching.
Anorectal Abscess :When anal glands become infected, bacteria or fecal matter can enter surrounding tissues and create an anorectal abscess. This infection around the anus or rectum is filled with pus and causes pain, swelling, skin irritation and fever. Draining the abscess relieves pain and pressure, and most people find relief after the procedure. Larger or deeper abscesses may require an operation.
Anal Fistula :Roughly half of all anorectal abscesses develop into a fistula, an abnormal channel that links infected anal glands to the opening of the skin around the anus. After the abscess has been drained, the passage between the anal gland and the opening in the skin may not always heal. Recurring drainage through the channel can cause fistula formation. Symptoms of an anal fistula are similar to those of an anorectal abscess: including Swelling, Skin irritation, Pus drainage,Fever.
Unlike anorectal abscesses, fistulas usually do not cause pain, but may produce drainage of fecal material.
