Anal fistula is the chronic phase of anorectal infection is characterized by chronic purulent drainage or cyclic pain associated with acute relapse of the abscess followed by intermittent spontaneous decompression. Perianal fistulas have a troublesome pathology. The most widely accepted theory is that anal abscess is caused by infection of an anal crypt gland. Suppuration moves from the anal gland to the inter-sphincteric space, forming an abscess leading to the development of a fistula. A fistula can cause pain, perianal swelling, discharge, bleeding, and other nonspecific symptoms.
Mayo Clinic doctors trained in colon and rectal surgery, gastroenterology, and infectious disease, as well as wound care experts, work together to evaluate and treat people with anal fistula. If you have Crohn's disease or another medical condition, Mayo Clinic specialists will collaborate with your primary care doctor to form the best treatment plan. Having all this expertise in a single place means that your care is discussed among the team, test results are available quickly, appointments are scheduled in coordination and the most highly specialized experts in the world are all working together for your health. Knowing the complete path of an anal fistula is important for effective treatment. The opening of the channel at the skin external generally appears as a red, inflamed area that may ooze pus and blood. This external opening is usually easily detected. Finding the fistula opening in the anus internal opening is more complicated.
AIM: Anal fistula is usually treated by either fistulotomy or fistulectomy. We described the routine use of setons to treat anal fistula without any surgery. Of the 47 patients, 15 had surgery previously for fistula and perianal abscess.
Cutting seton in management of complex perianal fistula — is it a safe procedure? Objective The aim of this study was to evaluate the effectiveness, frequency of incontinence, and recurrence after treatment of complex perianal fistula with cutting seton. Background Cutting seton commonly is prescribed for complex perianal fistula, because it is simple and cheap, but high incontinence rates suggest that cutting seton can damage continence musculature. Patients and methods A study was carried out in Damanhur Medical National Institute Colorectal Unit from October to October and included 30 patients with complex anal fistula.
