Anorectal refers to the lowest parts of the large intestine, including the anus and rectum.
- An anorectal abscess is an abscess that forms around the anus and rectum. An anorectal abscess begins with an infection of the anal glands, which progresses to an abscess that can drain spontaneously. If the patient seeks medical attention due to pain, the surgeon drains the abscess. An abscess is a precursor to a potential anal fistula (%30-40). Anorectal abscesses and fistulas are often thought of as two phases of the same infectious process. Anorectal abscesses (acute phase) typically occur as a result of an acute infection that originates from the anal glands or crypts. Abscesses can lead to the formation of a fistula (chronic phase).
- Anorectal fistula is a chronic, infected tunnel between the skin surrounding the anus and the anus-rectum. It does not heal spontaneously.
- Anorectal malformation; a congenital birth defect in which the anus and rectum fail to develop properly. There may be problems at various stages in the connection between the anus and rectum, resulting in anomalies such as narrowness, absence of an opening (imperforate anus), or the anus and rectum being far apart, with the rectum opening into the urinary tract or vagina. Surgical interventions are usually necessary to correct the problem.
- Anorectal manometry (rectal motility test) is a diagnostic test that measures the pressure and function of the muscles in the anus and rectum. It is used to evaluate disorders that affect bowel movements, such as fecal incontinence, constipation, or pelvic floor dysfunction.
- Anorectal angle: The angle formed between the anal canal and the rectum.
- Anorectal surgery: Surgical procedures performed in the anorectal region, such as hemorrhoidectomy or fistulotomy.
- Anorectal pain: Pain in the anus or rectum, often caused by conditions such as hemorrhoids or anal fissures.
- Anorectal physiology: The study of the normal function and behavior of the anus and rectum.
