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 ...
Posterior fistulas will have a curved track with their external opening lying in the posterior midline of the anal canal. An exception to the rule are anterior fistulas lying more than 3.75 cm from the anus, which may have a curved track (similar to posterior fistulas) that opens into the posterior midline of the anal canal.
Types of fistula can be described by their location. Anal fistulas connect between the epithelialized surface of the anal canal and the perianal skin. Anovaginal or rectovaginal fistulas occur when a hole develops between the anus or rectum and the vagina. Colovaginal fistulas occur between the colon and the vagina.
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]
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.
Surgical Therapy (for chronic fissures or when non-surgical therapy fails) : Anal Dilation, [8] Lateral Internal Sphincterotomy, Advancement Flaps, Fissurectomy. Anorectal Abscess and Fistula: Painful swelling, [5] Redness, Pain, [10] Bloody diarrhea, [11] an opening can point to a fistula, with or without drainage [5] with itchiness. [12]
Anorectal anomalies are congenital malformations of the anus and rectum. [1] One anal anomaly, imperforate anus has an estimated incidence of 1 in 5000 births. [2] [3] It affects boys and girls with similar frequency. [4] Examples of anorectal anomalies include: [citation needed] Anal stenosis; Proctitis; Anal bleeding; Anal fistula
A rectovestibular fistula occurs when the colon or rectum deviates anteriorly. [1] This leads to the formation of an abnormal connection between the rectum and the vulval vestibule, immediately posterior to the hymen, so that an ectopic anus opens into the fourchette, or frenulum, of the labia minora.
