Anal Fissure Surgery
An anal fissure is a tear in the lining of the anal canal. Most acute fissures improve with stool-softening measures and topical treatment; surgery is reserved for chronic fissures or severe symptoms that persist despite appropriate non-operative care.
Educational planning information. Individual advice follows examination and review of investigations. Consultations are available in Rawalpindi for patients from Rawalpindi and Islamabad.

01 · Understanding the procedure
What Anal Fissure Surgery is designed to achieve
Pain can cause the internal anal sphincter to spasm, reducing local blood flow and delaying healing. Chronic fissures may develop a skin tag or visible muscle fibres.

03 · Symptoms
Symptoms that may lead to a Anal Fissure Surgery consultation
Sharp or burning pain during and after a bowel movement
Bright red blood on toilet paper or the stool surface
A small skin tag near a chronic tear
Fear of opening the bowels can worsen constipation
Symptoms can overlap with other conditions. Severe, rapidly worsening or emergency symptoms require urgent medical assessment.

Why the condition behind Anal Fissure Surgery may develop
- 01
Passing a hard or large stool and constipation
- 02
Frequent diarrhoea or local trauma
- 03
Childbirth
- 04

06 · Diagnosis
How the need for Anal Fissure Surgery is assessed
A careful history and external inspection often establish the diagnosis. Examination is gentle because pain may be severe. Further tests are considered for recurrent, multiple, off-midline or non-healing fissures.
Clinical history
A careful history and external inspection often establish the diagnosis.
Focused examination
Examination is gentle because pain may be severe.
Laboratory testing
Further tests are considered for recurrent, multiple, off-midline or non-healing fissures.
Imaging
Imaging is chosen when it can define anatomy, disease extent or an alternative explanation for the symptoms.
Special investigations
Any endoscopy, tissue sampling, vascular study or other specialist test is selected for the clinical question raised by an anal fissure; not every patient needs every test.
07 · Treatment options
Treatment choices before and alongside Anal Fissure Surgery
Observation, lifestyle measures, medical care, a focused procedure or surgery may be considered according to the confirmed diagnosis.
Lifestyle & supportive care
Fibre, fluids, stool softeners and warm baths
Non-surgical option 02
Topical glyceryl trinitrate or calcium-channel blocker treatment when prescribed
Targeted treatment
Botulinum toxin injection
Surgical treatment
Lateral internal sphincterotomy or selected flap procedures
08 · Surgical indications
When Anal Fissure Surgery may be recommended
Surgery is discussed only when the diagnosis, expected benefit, alternatives and individual risks support intervention.
- A chronic fissure fails a full course of conservative and topical treatment
- Pain remains disabling or recurs repeatedly
- Sphincter function and continence risk have been assessed
09 · Procedure overview
The Anal Fissure Surgery care pathway
Consultation
Discuss symptoms, priorities, previous care and relevant reports before deciding whether Anal Fissure Surgery is appropriate.
Diagnosis
A careful history and external inspection often establish the diagnosis.
Preparation
The team reviews medicines, anaesthetic readiness and procedure-specific instructions for Anal Fissure Surgery.
Procedure
Lateral internal sphincterotomy divides a small part of the internal sphincter to reduce spasm Botulinum toxin temporarily relaxes the sphincter without cutting it
Recovery
Pain often improves as the fissure heals, but bowel movements may remain sensitive initially.
Follow-up
Healing, symptoms and the result of Anal Fissure Surgery are reviewed, with further care arranged when clinically necessary.
10 · Operative approach
How Anal Fissure Surgery may be performed
- 01
Lateral internal sphincterotomy divides a small part of the internal sphincter to reduce spasm
- 02
Botulinum toxin temporarily relaxes the sphincter without cutting it
- 03
Advancement flap may be considered when sphincter division carries higher continence risk
What Anal Fissure Surgery aims to improve
- High likelihood of fissure healing after appropriate selection
- Relief of pain and sphincter spasm
- Improved ability to pass stool comfortably
Balanced consent for Anal Fissure Surgery
- Bleeding, infection, abscess or recurrence
- Temporary urgency or leakage
- A small but important risk of persistent continence change, influenced by prior childbirth or sphincter injury
No operation can guarantee an outcome. Personal risk depends on diagnosis, anatomy, health and the final technique.
13 · Recovery timeline
Recovery checkpoints after Anal Fissure Surgery
Pain often improves as the fissure heals, but bowel movements may remain sensitive initially. Stool-softening measures continue during recovery to avoid re-injury. These checkpoints are planning prompts—not promises—and the treating team’s instructions take priority.
Week 1
Pain often improves as the fissure heals, but bowel movements may remain sensitive initially. Early priorities include pain control, safe movement and the first wound or procedure check when advised.
Week 2
Keep stool soft with fibre, fluid and prescribed medication Activity still follows the individual discharge plan.
Week 4
Use warm baths and pain relief as directed Return to work or exercise depends on the procedure and job demands.
Week 6
Avoid prolonged straining A slower or faster course can both be normal depending on the operation.
Long-term
High likelihood of fissure healing after appropriate selection Ongoing surveillance or specialist follow-up is arranged when the diagnosis requires it.
14 · Preparation
Preparing safely for Anal Fissure Surgery
01
Bring the complete record
Take reports, imaging, pathology and details of previous treatment relevant to an anal fissure.
02
Review medicines and allergies
Share prescribed medicines, blood thinners, diabetes treatment, supplements and allergies. Do not stop treatment without clinical instruction.
03
Complete pre-operative checks
A careful history and external inspection often establish the diagnosis.
04
Follow fasting instructions
Fasting depends on the anaesthesia plan for Anal Fissure Surgery; use the exact times supplied by the treating hospital.
05
Prepare for discharge
Arrange transport, suitable support and the supplies recommended for the expected commonly planned as a day-case procedure.
06
Know the recovery plan
Ask about wounds, bathing, diet, lifting, driving, work, exercise and the warning signs specific to Anal Fissure Surgery.
15 · Aftercare
Aftercare following Anal Fissure Surgery
Written discharge instructions are individualized. Keep them accessible and contact the treating team when recovery differs from the expected plan.
- Keep stool soft with fibre, fluid and prescribed medication
- Use warm baths and pain relief as directed
- Avoid prolonged straining
- Seek review for fever, increasing swelling, pus, heavy bleeding or new continence difficulty
16 · Patient questions
Frequently asked questions about Anal Fissure Surgery
Ten procedure-specific answers to support a more informed consultation.
01Will every fissure need surgery?+
No. Most acute fissures heal with bowel regulation and topical treatment.
02Why is continence discussed?+
The sphincter controls continence. Surgery that relaxes it is highly effective but must be balanced against individual risk.
03Can the fissure return?+
Yes, especially if constipation, hard stool or diarrhoea continues.
04How is the need for Anal Fissure Surgery confirmed?+
A careful history and external inspection often establish the diagnosis. Examination is gentle because pain may be severe. Further tests are considered for recurrent, multiple, off-midline or non-healing fissures.
05When might Anal Fissure Surgery be recommended?+
A chronic fissure fails a full course of conservative and topical treatment Pain remains disabling or recurs repeatedly
06Are there alternatives to Anal Fissure Surgery?+
Fibre, fluids, stool softeners and warm baths Topical glyceryl trinitrate or calcium-channel blocker treatment when prescribed Botulinum toxin injection
07What anaesthesia may be used for Anal Fissure Surgery?+
Local, regional or general, depending on the procedure. The anaesthetist confirms the safest option after reviewing the operation, medical history and individual risk.
08How long might I stay in hospital after Anal Fissure Surgery?+
Commonly planned as a day-case procedure. Discharge depends on the procedure, pain control, mobility, eating or drinking where relevant, and the absence of concerning findings.
09What should I expect while recovering from Anal Fissure Surgery?+
Pain often improves as the fissure heals, but bowel movements may remain sensitive initially. Stool-softening measures continue during recovery to avoid re-injury.
10Which warning signs matter after Anal Fissure Surgery?+
Follow the discharge instructions provided by the treating team. Important procedure-specific advice includes: Avoid prolonged straining Seek review for fever, increasing swelling, pus, heavy bleeding or new continence difficulty
