Anal fistula is a chronic abnormal communication between the anal canal and the perianal skin. [1] An anal fistula can be described as a narrow tunnel with its internal opening in the anal canal and its external opening in the skin near the anus. [2] Anal fistulae commonly occur in people with a history of anal abscesses. They can form when ...
Goodsall's rule relates the external opening (in the perianal skin) of an anal fistula to its internal opening (in the anal canal). It states that if the perianal skin opening is posterior to the transverse anal line, the fistulous tract will open into the anal canal in the midline posteriorly, sometimes taking a curvilinear course.
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 ...
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 ...
A fistulotomy is the surgical opening of a fistulous tract. [1] They can be performed by excision of the tract and surrounding tissue, simple division of the tract, or gradual division and assisted drainage of the tract in a seton; a cord passed through the tract in a loop that is slowly tightened over a period of days or weeks.
Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
Many different materials have been used as perianal injectable bulking agents. [9] Of the available materials, which one is the best is not known. [7] In 2013 a Cochrane systematic review included 5 randomized trials, which in total was 382 patients. None of the included studies reported long term follow up after 3, 6 or 12 months post ...
A high lesion, in which the colon is higher up in the pelvis and there is a fistula connecting the rectum and the bladder, urethra or the vagina. A persistent cloaca (from the term cloaca, an analogous orifice in birds, reptiles and amphibians), in which the rectum, vagina and urinary tract are joined into a single channel.
