A diagnostic test to evaluate the function of the muscles in the rectum and anus

Anorectal Manometry[edit]

Anorectal manometry is a diagnostic procedure used to evaluate the function of the muscles in the rectum and anus. This test is particularly useful in assessing conditions related to defecation disorders, such as fecal incontinence and constipation.

Purpose[edit]

The primary purpose of anorectal manometry is to measure the pressures of the anal sphincter muscles, the sensation in the rectum, and the neural reflexes that are necessary for normal bowel movements. It helps in diagnosing conditions like Hirschsprung's disease, anismus, and other anorectal disorders.

Procedure[edit]

During the procedure, a small, flexible tube with a balloon at the end is inserted into the anus and rectum. The balloon is inflated, and the pressures exerted by the muscles are recorded. The test typically lasts about 30 minutes and is performed on an outpatient basis.

Indications[edit]

Anorectal manometry is indicated for patients experiencing:

Chronic constipation
Fecal incontinence
Difficulty in passing stool
Suspected Hirschsprung's disease

Interpretation[edit]

The results of anorectal manometry provide information about:

Anal sphincter pressure
Rectal sensation
Rectoanal inhibitory reflex
Coordination of the muscles during defecation

Abnormal results may indicate dysfunction in the anal sphincter muscles or nerve supply, which can guide further treatment options.

+{{Short description|A diagnostic test to evaluate the function of the muscles in the rectum and anus}}
-Anorectal manometry is a diagnostic procedure that evaluates the function of the muscles in the rectum and anus. This test is crucial for individuals experiencing symptoms such as chronic constipation, fecal incontinence, or other anorectal disorders. The procedure involves measuring the pressures of the anal sphincter muscles, the sensation in the rectum, and the neural reflexes that are necessary for normal bowel movements.

+Anorectal manometry is a diagnostic procedure used to evaluate the function of the [[muscles]] in the [[rectum]] and [[anus]]. This test is particularly useful in assessing conditions related to [[defecation]] disorders, such as [[fecal incontinence]] and [[constipation]].
-==Procedure==
+=== Purpose ===
-The anorectal manometry procedure involves the insertion of a thin, flexible tube, equipped with a sensor, into the rectum. The sensor measures the pressures exerted by the internal and external anal sphincters. During the test, patients may be asked to perform various actions such as squeezing, holding, and pushing, to assess the function of the anorectal muscles and nerves. The procedure typically lasts about 20 to 30 minutes and is usually performed on an outpatient basis.

+=== Indications ===
 Anorectal manometry is indicated for patients experiencing:
-* [[Chronic constipation]]: Difficulty in passing stools over a long period.
+* Chronic constipation
-* [[Fecal incontinence]]: Inability to control bowel movements, leading to unintentional loss of stool.
+* Fecal incontinence
-* Anismus: A condition where there is a failure of the anal sphincter muscles to relax during defecation.
+* Difficulty in passing stool
-* Rectal prolapse: A condition where the rectal walls have prolapsed and can be seen outside the body.
+* Suspected Hirschsprung's disease
-* Pre and post-surgical evaluations: Assessing the anorectal function before and after surgical interventions for conditions like rectal cancer.
-==Results Interpretation==
+=== Interpretation ===
-The results from anorectal manometry can provide valuable information about the muscle tone and strength of the anal sphincters, coordination of rectal and anal muscles during defecation, and the sensitivity and function of the rectum. Abnormal results may indicate issues such as weak sphincter muscles, poor coordination between the rectum and anus, or reduced sensation in the rectum, which could contribute to anorectal dysfunction.

+Abnormal results may indicate dysfunction in the anal sphincter muscles or nerve supply, which can guide further treatment options.
-Anorectal manometry is generally considered a safe procedure with minimal risks. However, potential complications, although rare, can include:
-* Discomfort or pain during the procedure.
-* Minor bleeding, especially if there is an existing anal fissure or hemorrhoid.
-* Risk of infection, although this is extremely rare.
-==Follow-up==

-Based on the results of anorectal manometry, further diagnostic tests or treatments may be recommended. Treatment options may include dietary changes, pelvic floor physical therapy, biofeedback, or surgery, depending on the underlying condition and severity of symptoms.

-Anorectal manometry is a valuable diagnostic tool in the assessment of anorectal function. It provides essential information that can guide the management and treatment of various anorectal disorders, improving the quality of life for affected individuals.
