Anorectal abscess and fistula.
Associate Professor of Surgery, University of Vermont College of Medicine, Burlington, Vermont, USA.
Anorectal abscesses and fistulas are seen commonly in the primary care practice. An abscess forms as the result of obstruction of an anal gland, with resulting retrograde infection. An anal fistula simply represents the chronic phase of a perianal abscess. The history generally is diagnostic, and special studies usually are not required. Treatment is surgical, with good results.
