High Resolution Anal Manometry
Evaluating The Anal Sphincter Function
High-Resolution Anal Manometry evaluates anal sphincter function. It is done to evaluate incontinence and other disorders of defecation, including some forms of constipation. This procedure tests if there are appropriate pushing and relaxation to facilitate defecation and assesses various reflexes that control the sphincter. When done with a balloon expulsion test it can further evaluate the effectiveness of evacuation.
