Treatment, in the form of surgery, is considered essential to allow drainage and prevent infection. Repair of the fistula itself is considered an elective procedure which many patients opt for due to the discomfort and inconvenience associated with an actively draining fistula. [5] [3]
There is an uneven distribution of specialized health care providers due to the below optimal training and supervision of health works and the low wages of fistula surgeons. [33] Most fistula surgeons come from developed countries and are brought to developing countries, the nations more often affected by fistula, by a variety of organizations.
In anatomy, a fistula (pl.: fistulas or fistulae /-l i,-l aɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.
Rectovaginal fistulas are often the result of trauma during childbirth (in which case it is known as obstetric fistula), with increased risk associated with significant lacerations or interventions are used such as episiotomy or operative (forceps/vacuum extraction) deliveries [2] or in situations where there is inadequate health care, such as in some developing countries.
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar ) which is closely related to the antral floor.
A carotid-cavernous fistula results from an abnormal communication between the arterial and venous systems within the cavernous sinus in the skull. It is a type of arteriovenous fistula. As arterial blood under high pressure enters the cavernous sinus, the normal venous return to the cavernous sinus is impeded and this causes engorgement of the ...
The median time to definitive repair from fistula onset was 6 months (range 1 day to 28 months). The 6-month time course is commonly utilized by groups with significant experience treating fistulas, owing to the trend in encountering a less hostile abdomen than in the early phases. [ 4 ]
Globally, 75 percent of urogenital fistulas are obstructive labor fistulas. The average age of a woman who develops a fistula due to prolonged labor is 28 years old. The average age of a woman who develops a fistula from other causes is 42 years old. [8] Women with a small pelvis are more likely to develop a fistula.
