In medicine, a fistula (pl. fistulas or fistulae) is an abnormal connection or passageway between two epithelium-lined organs or vessels that normally do not connect. It is generally a disease condition, but a fistula may be surgically created for therapeutic reasons. [edit] Location of fistulasFistulas can develop in various parts of the body. The following list is sorted by the International Statistical Classification of Diseases and Related Health Problems. [edit] H: Diseases of the eye, adnexa, ear, and mastoid process

[edit] Types of fistulasVarious types of fistulas include:
Although most fistulas are in forms of a tube, some can also have multiple branches. [edit] CausesVarious causes of fistula are:
[edit] TreatmentTreatment for fistulae varies depending on the cause and extent of the fistula, but often involves surgical intervention combined with antibiotic therapy. Typically the first step in treating a fistula is an examination by a doctor to determine the extent and "path" that the fistula takes through the tissue. In some cases the fistula is temporarily covered, for example a fistula caused by cleft palate is often treated with a palatal obturator to delay the need for surgery to a more appropriate age. Surgery is often required to assure adequate drainage of the fistula (so that pus may escape without forming an abscess). Various surgical procedures are commonly used, most commonly fistulotomy, placement of a seton (a cord that is passed through the path of the fistula to keep it open for draining), or an endorectal flap procedure (where healthy tissue is pulled over the internal side of the fistula to keep feces or other material from reinfecting the channel). Treatments involving filling the fistula with fibrin glue or plugging it with plugs made of porcine small intestine submucosa have also been explored in recent years, with variable success. Surgery for anorectal fistulae is not without side effects, including recurrence, reinfection, and incontinence. It is important to note that surgical treatment of a fistula without diagnosis or management of the underlying condition, if any, is not recommended. For example, surgical treatment of fistulae in Crohn's disease can be effective, but if the Crohn's disease itself is not treated, the rate of recurrence of fistula is very high (well above 50%). [edit] Therapeutic useIn end stage renal failure patients, a cimino fistula is often deliberately created in the arm by means of a short day surgery in order to permit easier withdrawal of blood for hemodialysis. As a radical treatment for portal hypertension, surgical creation of a portacaval fistula produces an anastomosis between the hepatic portal vein and the inferior vena cava across the omental foramen (of Winslow). This spares the portal venous system from high pressure which can cause esophageal varices, caput madusae, and hemorrhoids. [edit] References
