Fissure vs Fistula — What’s the Difference?

Anal fissure and anal fistula are two common yet often confused anorectal conditions. While both cause discomfort and pain near the anal area, they differ in causes, symptoms, and treatment methods. Let’s explore how they differ and which treatment options offer the best outcomes.

What is an Anal Fissure?

An anal fissure is a small tear or crack in the lining of the anus, usually caused by passing hard stools or constipation. It results in sharp pain and bleeding during bowel movements.

  • ⚠️ Pain during or after bowel movement
  • ⚠️ Bright red blood on toilet tissue
  • ⚠️ Itching or burning sensation

What is an Anal Fistula?

An anal fistula is an abnormal tunnel that connects the anal canal to the skin near the anus. It often develops due to infection or abscess in an anal gland. This tunnel allows pus or discharge to drain from the infected area.

  • ⚠️ Swelling or pus discharge near anus
  • ⚠️ Persistent pain and irritation
  • ⚠️ Recurrent abscess formation

Fissure vs Fistula: Key Differences

Feature Fissure Fistula
Definition Small tear in anal lining Abnormal tunnel between anal canal and skin
Main Cause Constipation, hard stools Infection or abscess
Pain Type Sharp during stool passage Constant throbbing or dull pain
Discharge Rare Frequent pus or fluid
