This protocol addresses anorectal abscess arising in the intersphincteric plane — a presentation defined by the abscess forming between the internal and external anal sphincters. The intersphincteric location determines both the diagnostic approach and the surgical route required for effective drainage.
The abscess is confined to the intersphincteric space. This anatomical position distinguishes it from more superficial or deeper perianal collections and dictates a targeted surgical strategy to achieve adequate drainage while preserving sphincter integrity.

Intersphincteric abscesses should typically be drained through the intersphincteric groove or into the anal canal via an internal sphincterotomy.
