When it comes to anal health, many people confuse a fissure with a fistula—two very different conditions that affect the anus. While both may cause discomfort and are located in the same region, their causes, symptoms, and treatments are completely different.
In this blog, Dr. Nitin Jha, leading Laparoscopic and Colorectal Surgeon in Delhi NCR, explains how to differentiate between an anal fissure and an anal fistula, and when you should seek medical help.
What is an Anal Fissure?
An anal fissure is a small tear or cut in the thin, moist lining of the anus. It usually occurs due to trauma, such as:
- Passing hard or large stools
- Chronic constipation
- Straining during bowel movements
- Inflammation in the anal canal
🔹 Common Symptoms of Anal Fissure:
- Sharp pain during and after bowel movement
- Bleeding on the toilet paper or in the stool
- Burning or itching sensation near the anus
- A visible tear near the anal opening
Fissures are generally acute (lasting less than 6 weeks), but if not treated, they can become chronic, requiring more intensive care.
What is an Anal Fistula?
An anal fistula is an abnormal tunnel that forms between the inside of the anal canal and the skin near the anus. This condition typically develops due to:
- An abscess (infected gland) that drains
- Chronic infection in the anal gland
- Crohn’s disease or tuberculosis (in rare cases)
Common Symptoms of Anal Fistula:
- Persistent pain and swelling around the anus
- Discharge of pus or blood from a small opening near the anus
- Recurrent anal abscesses
- Skin irritation or redness
Fistulas do not heal on their own and almost always require surgical intervention.
Key Differences Between Fissure and Fistula
| Feature | Anal Fissure | Anal Fistula |
| Nature | Tear in the anal lining | Abnormal tract between anus and skin |
| Cause | Trauma from passing hard stool | Abscess or infection |
| Pain | Sharp, stabbing pain during bowel movement | Dull, constant pain that may worsen while sitting |
| Discharge | Fresh blood | Pus or foul-smelling discharge |
| Healing | Often heals with medication and lifestyle changes | Usually needs surgical treatment |
Diagnosis
Both fissures and fistulas are diagnosed through a clinical examination. In some cases, your doctor may suggest:
- Proctoscopy – to inspect the anal canal
- MRI or ultrasound – especially for fistulas to understand the tract
- Blood tests – to rule out infections or systemic diseases
Treatment Options
For Anal Fissure:
- High-fiber diet and hydration
- Stool softeners
- Topical ointments (nitrates, calcium channel blockers)
- Warm sitz baths
- In chronic cases: Lateral internal sphincterotomy (LIS) surgery
For Anal Fistula:
- Surgical treatment is the gold standard
- Fistulotomy – for simple fistulas
- Seton placement – for complex or high fistulas
- LIFT procedure – sphincter-saving technique
- Laser or VAAFT – minimally invasive options
- Antibiotics if there’s ongoing infection
When Should You See a Doctor?
If you’re experiencing any of the following, it’s time to consult a specialist like Dr. Nitin Jha:
- Persistent anal pain
- Bleeding or discharge from the anal area
- A lump or swelling near the anus
- Recurrence of anal abscess
- Delayed healing or worsening symptoms despite home remedies
Early diagnosis and proper treatment can help you avoid complications and chronic pain.
