A fistula involving the bladder can have one of many specific names, describing the specific location of its outlet: Bladder and intestine: "vesicoenteric", "enterovesical", or "vesicointestinal" [1] [2] [3] Bladder and colon: "vesicocolic" or "colovesical" [4] Bladder and rectum: "vesicorectal" or "rectovesical" [5]
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.
A rectovestibular fistula, also referred to simply as a vestibular fistula, is an anorectal congenital disorder where an abnormal connection exists between the rectum and the vulval vestibule of the female genitalia. If the fistula occurs within the hymen, it is known as a rectovaginal fistula, a much rarer condition. [1]
Sagittal section of the lower part of a female trunk, right segment. (Rectovaginal fascia not labeled, but region is visible.) Median sagittal section of female pelvis.
Vesicouterine fistulas occur most commonly after lower segment caesarean sections (about 83-93% of cases). [2] The possible mechanisms by which vesicouterine fistulas occur following caesarean sections include undetected bladder injury during caesarean section, inadvertent placement of a suture through the bladder during the repair of the uterus and abnormal blood vessel connections following ...
The equivalent structure in males is the rectovesical pouch, which is the pocket formed by the reflections of the peritoneum from the rectum to the male bladder. In terms of pelvic organ prolapse, a cul-de-sac hernia is located in the posterior compartment of the pelvis.
Fistulectomy is a surgical procedure where a surgeon completely removes a fistula, an abnormal tract (i.e. tube) that connects two hollow spaces of the body. [1] [2] In comparison to other procedural options of treating fistulae such as fistulotomies, where a fistula is cut open (i.e. unroofed) but not completely removed, and seton placement, where a rubber band seton is passed through 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 ]
