perianal abscess

Perianal abscess refers to a formed infective-inflammatory collection within the perianal region. It forms part of the broader group of anorectal abscesses. They are often associated with perianal fistulae and are components of grades 2 and 4 fistulae of the St James’ University Hospital classification .

Pathology

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

Associations

Recognized 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.
