Anal and rectal anometry

The anorectum plays an important role in regulation of defecation and in maintenance of continence [1]. The most widely used test for anorectal function is anorectal manometry. It measures pressures of the anal sphincter muscles, sensation in the rectum, and neural reflexes that are needed for normal bowel movements. Parameters studied by anorectal manometry are the rectoanal inhibitory reflex, anal resting pressure, sustained voluntary contraction of anal canal and rectal sensation [3]. Anorectal manometry is now available at multiple centres in India.

Our installations are provided with highly skilled professionals and cutting-edge technology to perform the digestive tests necessary to achieve an early and personalized diagnosis. This combination within the same space provides CMED physicians access to the tests of each patient from their computers. Esophageal manometry is a test recommended for the diagnosis of esophageal motor disorders or lower esophageal sphincter impairments in the context of symptoms such as dysphagia swallowing problems or gastroesophageal reflux. It is a diagnostic test aimed at measuring the function of the esophagus and its lower esophageal sphincter valve formed by a muscle which opens to swallow food to the stomach to then close and avoid regurgitation both of food and acids from the stomach. For the performance of the test, that lasts no more than 20 minutes, the digestive specialist places a thin probe through the nose getting to the stomach of the patient. This probe is connected to a computer which registers the pressure made by the lower esophageal sphincter and the esophageal body.

Anorectal manometry is the most well established and widely available tool for investigating anorectal function. Anal sphincter tone can be quantified by anorectal manometry. The anorectal sensory response, anorectal reflexes, rectal compliance, and defecatory function are also assessed by anorectal manometry. This report will focus on defining parameters for measurement and interpretation of anorectal manometry tests.

Anorectal manometry ARM is a medical test used to measure pressures in the anus and rectum and to assess their function. From to , the international anorectal physiology working group IAPWG meet several times to develop consensus on indications for anorectal manometry. Since its introduction in , high resolution anorectal manometry HR-ARM has increasingly replaced conventional anorectal manometry as the standard. After eliminating structural causes of fecal incontinence from the differential diagnosis , anorectal manometry may be used to evaluate deficiencies in sphincter function or anorectal sensation.
