Anаl Fissure 1. Bаckgrоund Definitiоn: A lineаr tear in the anоderm of the distal anal canal, typically at the posterior midline, causing severe pain during and after defecation. Pathophysiology: Tear results from trauma to the anal canal (hard stool, straining, constipation, or childbirth). Pain causes reflex spasm of the internal anal sphincter, reducing blood flow and impairing healing — creating a vicious cycle of pain and re-injury. Epidemiology: Common in young adults and postpartum women. May occur acutely or become chronic (>8 weeks). Atypical fissures (off-midline) may suggest underlying conditions: Crohn disease, tuberculosis, HIV, syphilis, or malignancy. 2. History Symptoms: Severe, sharp anal pain during bowel movements that may persist for minutes to hours afterward. Bright red blood on toilet paper or stool surface (not mixed in). Fear of defecation due to anticipated pain. Common triggers: Constipation, hard stools, prolonged diarrhea, childbirth, or anal trauma. 3. Exam Findings Inspection: Small linear tear in the distal anal canal, most commonly in the posterior midline (anterior in ~10% of women). May see sentinel skin tag or hypertrophied anal papilla in chronic fissures. Digital rectal exam or anoscopy: Often deferred in acute cases due to severe pain; diagnosis is usually clinical by inspection. Atypical locations (lateral or multiple fissures): Evaluate for underlying disease (Crohn, STI, malignancy). 4. Making the Diagnosis Clinical diagnosis: Based on characteristic pain and inspection findings. No further testing needed for typical midline fissure in a healthy patient. Consider additional evaluation (anoscopy, biopsy, colonoscopy) if: Fissure is off-midline, multiple, chronic, or nonhealing. Associated with systemic disease (IBD, infection, or cancer). 5. Management A. Conservative (First-line) Goal: Break the pain–spasm–ischemia cycle. Measures: High-fiber diet and stool softeners (docusate). Sitz baths after defecation. Topical anesthetics (lidocaine) for pain relief. Topical vasodilators (nitroglycerin ointment or calcium channel blockers like diltiazem or nifedipine) to reduce sphincter spasm and promote healing. B. Medical / Second-line Botulinum toxin injection into the internal anal sphincter for persistent fissures unresponsive to topical therapy. C. Surgical Lateral internal sphincterotomy for chronic fissures or failed medical management; highly effective but carries small risk of fecal incontinence. D. Prevention Maintain soft, regular stools with fiber, fluids, and avoidance of straining. Question A 34-year-old woman presents with severe sharp anal pain during and after bowel movements for the past two weeks. She also notes small amounts of bright red blood on toilet paper. She reports a history of constipation but no previous rectal problems. Physical examination reveals a small linear tear at the posterior midline of the anal canal.
