Definitive treatment of a fistula aims to stop it recurring. Treatment depends on where the fistula lies, and which parts of the internal and external anal sphincters it crosses. However, treatment is challenging as complete eradication of the anal sphincters may lead to continence impairment, but failure to excise the affected areas results in ...
Despite treatment, re-bleeding occurs in about 7–16% of those with upper GI bleeding. [3] In those with esophageal varices, bleeding occurs in about 5–15% a year and if they have bled once, there is a higher risk of further bleeding within six weeks. [13] Testing and treating H. pylori if found can prevent re-bleeding in those with peptic ...
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Anorectal abscess (also known as an anal/rectal abscess or perianal/perirectal abscess) is an abscess adjacent to the anus. [1] Most cases of perianal abscesses are sporadic, though there are certain situations which elevate the risk for developing the disease, such as diabetes mellitus, Crohn's disease, chronic corticosteroid treatment and others.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
The cord provides a path that allows the fistula to drain continuously while it is healing, rather than allowing the exterior of the wound to close over. Keeping the fistula tract open can help prevent the trapping of pus or other infectious material in the wound. The procedure was mentioned by Hippocrates.
To a large extent the risk of developing an aneurysm can be reduced by carefully rotating needle sites over the entire fistula ("rope-laddering" [3]), or using the "buttonhole" (constant site) technique; button-holing is safe when a fistula is used, but runs the risk of infection or degradation of an arterio-venous graft. [3]
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.
