An anal fissure is a small tear in the lining of the anal canal. Pain-sensitive nerve fibres in this region make it one of the most painful conditions in coloproctology. Pain is often described as passing broken glass, deterring toilet use and worsening the constipation that sustains the fissure.
Acute fissures (under six weeks) heal in the majority of cases with conservative management. Chronic fissures (beyond six weeks) develop a sentinel pile (skin tag), hypertrophied anal papilla, and rolled fibrous edges that block spontaneous healing and require medical or surgical treatment. At Ramkrishna CARE Hospitals our expert specialists manage anal fissures with a comprehensive approach and advanced surgical treatments tailored to the condition's severity.
Symptoms of Anal Fissure
The symptom pattern is highly characteristic and allows clinical diagnosis in most cases:
- Severe pain during defecation: Sharp, tearing or burning at the moment of passing stool
- Post-defecatory pain: Pain lasting 30 minutes to several hours after defecation, caused by reflex spasm of the internal anal sphincter (the involuntary muscle keeping the anus closed)
- Bright red rectal bleeding: Small amount of fresh blood on toilet paper or stool surface and never mixed through the stool
- Itching and perianal irritation: Common in chronic fissures with a sentinel pile and mucus
- Fear of defecation: Pain anticipation causes toilet avoidance, harder stools and a self-perpetuating cycle of re-tearing
- Visible tear: Usually visible in the posterior midline in the majority of cases
Causes of Anal Fissure
Anal fissures result from trauma to the anal mucosa combined with sphincter spasm and poor blood supply that prevent healing. This can occur from:
- Constipation and hard stools: A hard stool tears the mucosa and repeated micro-tears prevent healing
- Sphincter hypertonia: Persistent spasm causes ischaemia (poor blood supply) at the posterior commissure, preventing healing; this makes fissures self-perpetuating
- Childbirth trauma: Perineal tearing during delivery causes anterior midline fissures in women
- Chronic diarrhoea: Repeated loose stools irritate and erode the anal mucosa
- Anal intercourse: Mechanical trauma to the anal canal
- Crohn's disease: Lateral, multiple, or complex fissures with perianal tags or fistulae
- Sexually transmitted infections: Syphilis, herpes simplex and HIV cause anal ulceration that resembles or coexists with fissure.
Anal Fissure Diagnosis
Diagnosis is clinical; post-defecatory pain with bright red bleeding is a unique characteristic of anal fissure:
- History: Onset, duration, pain pattern, bleeding, bowel habit and family history of inflammatory bowel disease
- Perianal inspection: Reveals the fissure at the posterior midline, a sentinel pile, or lateral fissures (raises suspicion for Crohn's disease)
- Digital rectal exam (DRE): Performed to check a hypertonic (tight) internal sphincter but if too painful, history and inspection alone suffice
- Proctoscopy: Excludes haemorrhoids when bleeding is prominent
- Colonoscopy or MRI: To detect atypical fissures, Crohn's disease, STIs, or malignancy.
Risk of Anal Fissure
Anal fissures can affect anyone, but these groups carry a higher risk:
- Infants: From hard stools and a tight anal opening
- Young adults: Peak adult incidence between 15 and 40 years
- Pregnant women: Constipation and perineal trauma during delivery predispose to fissures
- Chronic constipation: The strongest adult risk factor
- Previous anal surgery: Fibrotic scar tissue from prior procedures is susceptible to tearing.
Complications of Anal Fissure
Untreated chronic fissures lead to a cycle of pain and progressive complications:
- Chronic fissures develop a sentinel pile, hypertrophied papilla and rolled fibrous edges
- Prolonged sphincter spasm causes functional anorectal dysfunction
- Perianal abscess and fistula-in-ano
- Severe quality of life impact, including disrupted sleep, dietary avoidance and social withdrawal
- Incontinence risk.
Anal Fissure Treatment Options
Treatment depends on the stage. Acute fissures respond to conservative measures, whereas chronic fissures require medical therapy and sometimes surgery. Treatment options are:
- Conservative Treatment
- A high-fibre diet (25 to 35 g daily), 2 litres of water, isabgol and stool softeners soften stools and reduce straining. Warm sitz baths (10 to 15 minutes twice daily) relax the sphincter. The majority of acute fissures heal with these measures alone.
- Topical Medications: For fissures not responding to diet alone topical medications relax the internal sphincter and restore blood flow:
- Topical anaesthetics: Reduce pain and discomfort around the affected area during bowel movements.
- Topical nitrates or calcium channel blockers: Relax the sphincter, improve blood flow and support healing
- Botulinum toxin: Results in temporary chemical sphincterotomy.
- Surgical Treatment
- Lateral internal sphincterotomy (LIS): LIS is the definitive treatment for chronic fissures that are not responding to medical therapy. A small portion of the internal anal sphincter muscle is divided to reduce hypertonia, restore blood flow and allow the fissure to heal. LIS is the gold standard for chronic refractory fissures.
At Ramkrishna CARE Hospitals, Raipur, LIS is a day-case procedure taking 15 to 20 minutes under spinal anaesthesia. Laser-assisted sphincterotomy and fissurectomy are also available for selected patients.
What is the Procedure of Anal Fissure Treatment?
The procedure is structured and stage appropriate:
- Consultation and assessment: History and perianal examination confirm diagnosis, identify acute versus chronic and exclude Crohn's disease.
- Conservative and medical treatment: High-fibre diet, sitz baths and stool softeners started immediately. Topical creams are prescribed and doctors review the condition at 6 to 8 weeks.
- Botulinum toxin injection: It is usually a day-care procedure and Botulinum toxin is injected into each side of the internal sphincter under direct vision and discharged the same day.
- Lateral internal sphincterotomy (LIS): LIS is typically performed as a day-care procedure under spinal or local anaesthesia. A small lateral incision is made to divide lower internal sphincter fibres under direct vision. The wound is usually closed with dissolvable sutures, and most patients can return home within a few hours of the procedure.
- Postoperative care and follow up: Doctors advise sitz baths for 4 to 6 weeks, follow-up at 4 weeks and permanent dietary habits to prevent recurrence.
Benefits of Anal Fissure Treatment
Effective fissure treatment results in:
- Complete pain relief
- Resolution of rectal bleeding
- Normal bowel function is restored and the fear of defecation and resulting constipation are eliminated.
- Early treatment prevents complications like fistula and abscess development.
- High success rates
- Short recovery - Botox is same-day and LIS returns patients to normal activity within 5 to 7 days.
