Anal abscess and fistula

Abstract

Benign anorectal diseases, such as anal abscesses and fistula, are commonly seen by primary care physicians, gastroenterologists, emergency physicians, general surgeons, and colorectal surgeons. It is important to have a thorough understanding of the complexity of these 2 disease processes so as to provide appropriate and timely treatment. We review the pathophysiology, presentation, diagnosis, and treatment options for both anal abscesses and fistulas.
