| 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.
