If an abscess develops in a superficial gland, it is most likely to discharge spontaneously into the anal canal. However, if the abscess is lo-cated deep to the internal sphincter, the sphincter can act as a barrier.

The blood vessels to the anoderm course through the internal anal sphincter (IAS). Therefore hypertonicity of the IAS may thereby decrease blood flow and cause ischaemia to this region.

Principles of Surgery - Anal Abscess and Fistula

An anal fistula is a tunnel-like tract between the lining of the anal canal and the skin around the anus. A fistula forms usually after an anal abscess has drained spontaneously or following surgical drainage. Because the tract is lined with chronic infection it tends not to heal and there is a persistent discharge of pus.
