Common Name:

ANAL FISSURE

Medical Term:

Fissure-in-Ano
Description:

A tear or ulcer in the lining of the anus, causing pain on defecation.

Causes:

Causes include stretching of the anal wall by large hard stool or tightening of the anal canal due to tension or the laceration by foreign body.

Prevention:

Avoid constipation by: Drinking at least 8 glasses of water daily; Eating a diet high in fiber; Using stool softeners if needed; Don't strain at stool; Avoid anal intercourse.

Signs & Symptoms

Painful bowel movement associated with bright red bleeding.

Pain then subsides and recurs with the next bowel movement.

Streaks of blood on toilet paper, underwear or diaper.

May become chronic, with periods of exacerbation or remission

Fissure causes the sphincter to go into a spasm, which may prevent healing.

Risk Factors

Constipation

Multiple pregnancies

Leukemia

Crohn's disease

Immunodeficiency disorders

Chronic use of laxatives

Diagnosis & Treatment
General Measures:

Examination of the anus and rectum with an anoscope or sigmoidoscope to rule out other causes of anal or rectal bleeding.

Gently clean the anal area with soap and water after each bowl movement

To relieve muscle spasms and pain around the anus, apply a warm towel to the area

Sitz baths also relieve pain. Use 8 inches of warm water in the bathtub, 2 or 3 times a day for 10 to 20 minutes.

Surgery may be necessary, if conservative treatment is not successful, to remove the fissure or to alter the muscle that contracts and prevents normal healing

Medications:

For minor pain, use non-prescription drugs, such as acetaminophen or topical anesthetics.

Zinc oxide ointment or petroleum jelly applied to the anal opening may help to prevent the burning sensation.

Bulk stool softeners will help to avoid the pain occurring with bowel movements.

Lidocaine ointment may be recommended.

Activity:

No restrictions. Physical activity reduces the likelihood of constipation.

Diet:

A high-fiber diet and extra fluids (ie. 8 glasses of water a day) to prevent constipation are recommended.

Possible Complications :

Permanent scarring that prevents normal bowel movements.

Prognosis

Most adults recover in 4 to 6 weeks with treatment, making surgery unnecessary. Most infants and young children recover after the stool is softened.
