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 ...
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 manometry is sometimes used to investigate changes in the anal canal before and after the procedure. Usually mean anal resting pressure and mean anal squeeze pressure are the parameters used. [3] Improvements in these measurements are often, but not always reported up to 3–12 months after the procedure.
Unlike other surgeries for anal incontinence, a preliminary colostomy is not necessary for Warren operation. The surgery is planned in such a way that it takes place 2–3 days after the cessation of menstrual flow, such that there is ample time for the surgical wound to heal until the next menses.
The internal anal sphincter receives extrinsic autonomic innervation via the inferior hypogastric plexus, with sympathetic innervation derived from spinal levels L1-L2, and parasympathetic innervation derived from S2-S4. [23] Disruption of the function of the internal anal sphincter results in reduced resting pressure in the anal canal.
Perineoplasty (also perineorrhaphy) denotes the plastic surgery procedures used to correct clinical conditions (damage, defect, deformity) of the vagina and the anus. [1] [2] [3] Among the vagino-anal conditions resolved by perineoplasty are vaginal looseness, vaginal itching, damaged perineum, fecal incontinence, genital warts, dyspareunia, vaginal stenosis, vaginismus, vulvar vestibulitis ...
The internal anal sphincter, IAS, or sphincter ani internus is a ring of smooth muscle that surrounds about 2.5–4.0 cm of the anal canal. It is about 5 mm thick, and is formed by an aggregation of the smooth (involuntary) circular muscle fibers of the rectum.
