    Area of Science:

    • Gastroenterology
    • Colorectal Surgery

    Context:

    • Anal fissure etiology is debated, with multiple theories proposed.
    • Histologic and manometric studies indicate internal anal sphincter abnormalities in patients with anal fissures.
    • Current medical management principles lack robust evidence from controlled studies.

    Purpose:

    • To review the current understanding of anal fissure etiology and management.
    • To evaluate the effectiveness of different surgical interventions for anal fissures.

    Summary:

    • Surgical treatment for anal fissures involves internal sphincter laceration.
    • Lateral sphincterotomy demonstrates superior results in reducing recurrence and incontinence compared to other methods.
    • Posterior sphincterotomy is associated with a higher incidence of incontinence and key-hole deformity.
