For education and visit preparation; individual assessment requires a clinical history and examination.
What does the operation change?
Lateral internal sphincterotomy reduces sphincter pressure in selected patients with a chronic anal fissure. It is a different operation from opening a fistula tract. Examination and confirmation of the diagnosis come first.
Why is duration alone insufficient?
The clinician reviews the fissure, previous treatment and response. Persistent pain can require reassessment, particularly with an unusual pattern. A long history alone does not establish that cutting the sphincter is appropriate.
Continence history matters
Describe any gas or stool leakage, childbirth-related injury and previous anal operations. These details help balance healing against the risk of altered control and can make another approach preferable.
Before agreeing to surgery
Ask about the intended extent of the operation, alternatives, wound care and follow-up. General healing figures are not a guarantee for an individual. Make sure the discussion includes both symptom relief and continence.
Questions for your appointment
- Why is surgery appropriate for this fissure?
- How does my existing continence affect the choice?
- What alternatives are available if my risk is higher?
