Treatment for Anal Fissure
Treatment for anal fissure aims to relieve pain, heal the tear, and prevent recurrence. Most acute fissures heal within a few weeks with proper care. Chronic fissures, however, may need medications or even surgery.
Home Remedies and Lifestyle Changes
- High-fibre diet
- Include fruits, vegetables, whole grains, and legumes
- Helps soften stools and reduce straining
- Hydration
- Drink at least 1.5 to 2 litres of water daily
- Warm sitz baths
- Soak the anal area in warm water for 10–15 minutes, 2–3 times a day
- Relaxes the anal muscles and promotes healing
- Stool softeners or mild laxatives
- Prevent constipation and hard stools
- Proper hygiene
- Gently pat dry after bowel movements
- Avoid perfumed soaps and excessive wiping
Medications
- Topical anaesthetics
- Lidocaine creams help reduce pain temporarily
- Nitrate creams (e.g. glyceryl trinitrate)
- Promote blood flow to the area, speeding up healing
- May cause mild headaches
- Calcium channel blockers (e.g. diltiazem ointment)
- Alternative for patients who don’t tolerate nitrates
- Botox injections
- Temporarily paralyse the anal sphincter to allow healing
- Used in chronic fissures not responding to ointments
Surgery
If conservative treatment fails after 6–8 weeks, surgery may be considered:
- Lateral internal sphincterotomy is the most effective procedure
- Involves cutting a small portion of the anal sphincter muscle to reduce spasm
- Success rate is over 90%, but there is a small risk of incontinence
Treatment decisions depend on the fissure’s duration, severity, and the patient’s overall health. Now let’s look at possible complications and how to avoid them.
