New Trends In Management of Perianal Fistula Disease
Ahmed Mohammed Shaaban;
Abstract
A fistula-in-ano is an abnormal tract or cavity communicating with the rectum or anal canal by an identifiable internal opening. It is characterized by chronic purulent drainage or cyclical pain associated with abscess formation.
Widely accepted cryptoglandular theory leading to abscess formation and fistula development needs to be well understood as this is the pathology responsible for almost 90% of the perineal sepsis and anal fistulas. Although the most common etiology for perianal fistula is an anorectal abscess, other etiologies include crohn’s disease, hidradenitis suppurativa, trauma, prior anal surgery, infections (such as HIV, tuberculosis, or actinomycosis), and malignancy.
Classification of fistula in ano is of immense importance as it gives accurate description of the anatomy of the course of the fistulous tract which is helpful to a surgeon in planning the operative cure of the disease. They are usually classified based on relation to the anal sphincter complex. Park classified the fistulas into transsphincteric, intersphincteric, supra-sphincteric and extra-sphincteric. These terms are quite informative in relation to the sphincter apparatus.
A successful outcome from any type of fistula operation is dependent on accurate clinical assessment
