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 ...
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.
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 ...
In 1993 Matos et al. described a technique of total anal sphincter preservation in high fistula in ano, which is based on the concept of excision of intersphincteric anal gland infection through the intersphincteric approach. [3] This novel technique was also documented in Corman’s textbook of colon and rectal surgery. [4]
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 ...
Anal encirclement effectively supplements the anal sphincter, narrowing the anal canal and its barrier function to stool, without altering voluntary control. Since complications are common, and can be serious (fecal impaction, infection, erosion of encirclement through anal canal), modern surgeons prefer to perform colostomy.
