What are fistulas?

In medicine, the tubes are similar to passages that either form abnormally or are surgically created in the body. Fistula can connect to organs or blood vessels, or could combine the surface of the skin to an internal organ or container. As a result of the disease, they can be unusually formed in the body.

In general, fistula is described on its location in the body. For example, arteriovenous (AV) fistula combines artery and vein. It is also a good example of surgically formed fistulas designed for long -term medical treatment, such as dialysis in patients with the final stage of kidney failure. Blind fistulas have only one open end, while the complete holes have externally and internally. Incomplete fistulas have external opening, but they do not connect anything.

The causes of the fistula are diverse. Diseases can cause them, as well as a certain medical treatment and trauma or body injury. Conditions such as Crohn's disease and colitis are common inflammatory bowel diseases that cause anorectal fistula. TrAuma to the body, such as prolonged, severe birth, which can cause obstetric fistula, can also be a culprit. Their creation as a result of severe birth occurs most often in parts of the world where professional medical care is poor or non -existent.

Fistula treatment varies according to the cause, location, size and type. Some small, which are the result of injury to heal themselves. In some cases, if they are caused by a disease or condition such as infection, treatment may include antibiotics. If fistula disrupts normal and necessary body functions such as blood flow, surgery may be necessary to repair the hole. The diagnosis varies depending on the ND atyp site. Surgically created passages usually require a vascular surgeon and are carefully monitored in terms of healing and functionality.
