Anal sphincterotomy is a surgical procedure that involves treating mucosal fissures from the anal canal/sphincter. [ 1 ] [ 2 ] The word is formed from sphincter + otomy (to cut, to separate). [ 3 ]
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.
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 ...
Warren operation is a surgery performed to correct anal incontinence. It is done by disrupting the anterior segment of the anal sphincter , perineal body and rectovaginal septum . [ 1 ]
This may bring the walls of the anal canal into tighter contact, raising the resting pressure, creating more of a barrier to the loss of stool, and thereby reducing fecal incontinence. This procedure has many advantages over more invasive surgery, since there are rarely any serious complications. [3]
This is the case even in the presence of tears of the external anal sphincter or internal anal sphincter. [6] Therefore, the implants are placed in the above locations for convenience of the surgeon, even for patients with a tear in a specific part of the sphincter. [6] The incisions are closed with resorbable sutures.
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]
In other sources, the term anal incontinence is distinguished as involuntary loss of feces or flatus caused by loss of control of the anal sphincter; [31] [32] whereas fecal incontinence may be given the definition of involuntary loss of solid or liquid feces which may also be caused by enlarged skin tags, poor hygiene, hemorrhoids, rectal ...
