Introduction
If you have been suffering from a fissure for weeks or months without lasting relief, you are not alone and you are not out of options. In this blog, Dr. Trisha Rai, Noida’s trusted female proctologist, explains exactly why chronic fissures develop, why they struggle to heal on their own, and most importantly, how to get rid of a chronic fissure permanently.
Why Does a Fissure Become Chronic?
Understanding why a fissure becomes chronic is essential to understanding why standard home remedies stop working for these cases.
1. The Pain-Spasm Cycle
When an anal fissure develops, the pain triggers a reflex spasm of the internal anal sphincter muscle. This spasm reduces blood supply to the already-injured tissue, preventing healing. The next bowel movement reopens the wound, causing more pain and more spasm. This self-perpetuating cycle is the primary reason acute fissures progress to chronic ones.
2. Fibrotic Tissue Formation
Over time, the repeated trauma and failed healing attempts cause the edges of the fissure to become hardened and fibrotic, thick,- non-elastic scar tissue that is incapable of the normal tissue regeneration required for healing.
3. Sentinel Skin Tag and Hypertrophied Papilla
In chronic fissures, a sentinel skin tag typically develops at the outer edge of the fissure and a hypertrophied anal papilla at the inner edge. These structures are markers of chronicity and confirm that conservative treatment alone is unlikely to achieve complete healing.
4. Reduced Local Blood Supply
The posterior anal canal, where the majority of fissures occur, already has a limited blood supply. Chronic spasm further reduces circulation to this area, compounding the healing deficit.
Conservative Treatments: What Works and What Doesn’t
For chronic fissures, conservative treatments provide symptomatic relief but rarely achieve permanent healing. Understanding their limitations helps set realistic expectations.
- Topical anesthetic creams reduce pain temporarily but do not address the underlying muscle spasm or promote tissue healing.
- Topical Glyceryl Trinitrate (GTN) Cream relaxes the internal anal sphincter, improving blood supply and reducing spasm. Effective for some acute-to-subacute fissures but has a high recurrence rate in truly chronic cases. Headaches are a common side effect.
- Diltiazem cream is a calcium channel blocker that relaxes sphincter spasm with fewer side effects than GTN. More effective than GTN for longer-term use but still insufficient for established chronic fissures with fibrotic edges.
- Botulinum Toxin Injection Botox injected into the internal anal sphincter provides temporary muscle relaxation for 2–3 months. This window of reduced spasm can allow healing in some subacute cases. However, it has a significant recurrence rate in fully chronic fissures and requires repeat injections.
- Sitz baths and dietary modification remain important supportive measures regardless of other treatment being used. They do not cure chronic fissures but support overall comfort and bowel regularity.
Definitive Treatment: How to Permanently Get Rid of a Chronic Fissure
For truly chronic fissures, those with fibrotic edges, sentinel tags, and a history of failed conservative treatment, surgical intervention is the most reliable path to permanent relief.
Laser Fissure Treatment: The Most Advanced Option
Laser fissure treatment is the most effective and least invasive surgical option for chronic anal fissure. Dr. Trisha Rai uses precise laser energy to remove the fibrotic edges of the chronic fissure, stimulate fresh tissue regeneration, and relax the internal anal sphincter all without cutting the muscle or creating large wounds.
Benefits of laser fissure treatment:
The procedure takes 20–30 minutes under short anesthesia. There is no pain during the procedure. Most patients are discharged the same day. Return to normal activities is possible within 24–48 hours. The recurrence rate is significantly lower than traditional surgery. There is no risk of incontinence; the sphincter is not cut.
Lateral Internal Sphincterotomy (LIS)
LIS is the traditional gold standard surgical treatment for chronic fissures. A small portion of the internal anal sphincter is divided to permanently relieve the muscle spasm that prevents healing. It has a high success rate but carries a small risk of incontinence, particularly in women and older patients. Dr. Trisha Rai recommends laser treatment as a first option precisely because it achieves comparable healing without any sphincter division.
Fissurectomy
Surgical excision of the fibrotic fissure edges combined with removal of the sentinel tag allows fresh tissue to fill the wound and heal properly. Often combined with sphincter relaxation techniques for optimal outcomes.
Dr. Trisha Rai’s Approach to Chronic Fissure
Dr. Trisha Rai follows a structured approach to every chronic fissure case. The consultation begins with a thorough history to understand symptom duration, previous treatments, dietary habits, and bowel patterns. A gentle examination confirms the diagnosis and assesses the degree of chronicity. Conservative options are discussed honestly, including their limitations for established chronic cases. Laser fissure treatment is explained in detail, including procedure, recovery, and expected outcomes. The procedure is performed at a convenient appointment with complete pre-operative preparation. Post-operative dietary guidance and follow-up appointments ensure complete healing.
Lifestyle Changes to Support Healing and Prevent Recurrence
Even after successful laser treatment, these lifestyle habits are essential to prevent recurrence. Maintain a consistently high-fiber diet with at least 25–30 grams of fiber daily. Drink 8–10 glasses of water every day. Never strain during bowel movements. Take short walks daily to maintain bowel regularity. Continue sitz baths for at least 4–6 weeks after treatment. Attend all scheduled follow-up appointments with Dr. Trisha Rai.
FAQ
Q: How long does a fissure have to last to be considered chronic?
A: A fissure that persists for more than 6 weeks despite conservative treatment is classified as chronic. The presence of fibrotic edges and a sentinel skin tag confirms chronicity regardless of duration.
Q: Can a chronic fissure ever heal without surgery?
A: In a small number of cases, intensive conservative treatment, including Botox injection and topical muscle relaxants, can achieve healing. However, for the majority of chronic fissures with established fibrotic tissue, surgical intervention provides the most reliable permanent relief.
Q: Is laser treatment painful for chronic fissure?
A: The procedure is performed under anesthesia; there is no pain during surgery. Post-operative discomfort is minimal and well managed with prescribed medications.
Q: How quickly can I return to work after laser chronic fissure treatment?
A: Most patients return to desk work within 24–48 hours after laser fissure treatment. Physical work should be avoided for 1–2 weeks.
Q: Will my chronic fissure come back after laser treatment?
A: Laser treatment for chronic fissure has a low recurrence rate. Maintaining a high-fiber diet, adequate hydration, and avoiding constipation significantly reduces the risk of recurrence.
Q: How many follow-up visits are needed after chronic fissure treatment?
A: Dr. Trisha Rai typically schedules 2–3 follow-up visits after laser fissure treatment to monitor healing progress and ensure complete recovery.
