Perianal abscess refers to a formed infective-inflammatory collection within the perianal region. It forms part of the broader group of ~~ano-rectal~~anorectal abscesses.

They are often associated with perianal fistulae and are components of grades 2 and 4 fistulae ~~under the classification system suggested~~of the St James ~~University. UK~~’ university hospital classification ².

Pathology

Infection and anal gland drainage obstruction from the perianal fistula may lead to an acute perianal abscess.

Associations

Recognised associations include:

diabetes mellitus
Crohn disease
pelvic infection
trauma
anorectal cancer/anal cancer +/- radiation therapy

Treatment and prognosis

While some abscesses may resolve spontaneously via internal drainage into the anal canal, others may require surgical incision and drainage.
