An anal fissure is a tear in the lining of the lower rectum anal canal that causes pain during bowel movements. Anal fissures don't lead to more serious problems. Most anal fissures heal with home treatment after a few days or weeks. These are called short-term acute anal fissures. If you have an anal fissure that hasn't healed after 8 to 12 weeks, it is considered a long-term chronic fissure.
Hemorrhoids and fissures occur in the rectum when chronic constipation and more tender damage anal tissues. A hemorrhoid is a pile of inflamed varicose veins in the inner layer of the rectum and anus. You should look out for an extended area of skin just beyond the anus if afflicted with external hemorrhoid. These are dilated veins that gradually extend repeated deformity and are pushed outward towards the anus. You can treat external hemorrhoids with oral medications and ointments to apply locally.
An anal fissure is a common, mostly benign, condition that can be acute or chronic. The diagnosis is usually made on history and physical examination, but further investigations are sometimes necessary. Primary fissures are usually benign and located in the posterior or anterior position. Secondary fissures are lateral or multiple and often indicate a more serious underlying pathology. The management of primary anal fissures is generally non-operative and includes increased dietary fibre, sitz baths, topical ointments and botulinum toxin injections.
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. Anal fissures can occur at any age and have equal gender distribution. A small number of patients may actually have fissures in both the front and the back locations.
