Background:
Anal fissure (AF) is the second most common anorectal complaint in healthcare settings. The presentation might be acute or chronic, characterised by severe pain with defaecation that persists for one to two hours. Non-surgical and surgical interventions are available based on the severity and persistence of the fissure.
Objective:
The aim of this article is to review the pathophysiology, clinical presentation and management of AF under current guidelines.
Discussion:
The aetiology of AF is unclear, although it is commonly associated with local trauma or associated chronic conditions. Acute AF is first treated with conservative therapy, including dietary fibre and sitz baths. Addition of topical nitrates, topical calcium channel blockers or botulinum toxin injection is indicated with failure of conservative treatment or at medical discretion. Surgical options are considered if AF persists despite treatment. Most present as hypertonic, but special consideration is needed for hypotonic or secondary presentations.
