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]
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.
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.
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] Some evidence also suggests that somatostatin can be an effective treatment with respect to reducing closure time and improving the spontaneous closure rate ...
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.
First- and second-degree tears rarely cause long-term problems. Among women who experience a third- or fourth-degree tear, 60–80% are asymptomatic after 12 months. [24] Faecal incontinence, faecal urgency, chronic perineal pain, pain with sex, and fistula formation occur in a minority of women, but may be permanent. [25]
If fecal matter passes through the fistula into the bladder, the existence of the fistula may be revealed by pneumaturia, fecaluria, or recurrent urinary tract infection. Migration of urine through the fistula into the bowel may cause rectal passage of urine. [6]
The presence of a vaginal fistula has a profound effect on the quality of life since there is little control over the passage of urine and feces through the vagina. [6] [7] Urogenital fistulas are often classified according to their cause: obstetric fistula, congenital fistula and iatrogenic fistula. Urogenital fistulas can be classified by ...
