What is LIS?
Lateral Internal Sphincterotomy involves:
- Making a small cut in the tight internal anal muscle
- Reducing pressure in the anal canal
- Allowing the fissure to heal naturally
It directly treats the root cause — muscle tightness.
When is LIS Recommended?
LIS is advised if:
- Fissure lasts more than 6–8 weeks
- Severe pain during motion continues
- Recurrent fissure problem
- Failure of ointments and medicines
A proper clinical evaluation will decide if this is the right treatment for you.
