Are there any alternatives to anorectal manometry?

In cases where muscle or nerve problems are thought to be the cause of bowel symptoms, anorectal manometry is usually the most accurate test for diagnosis. Unlike imaging, which shows the structure of the bowel, manometry measures how well the muscles and nerves are actually working. For this reason, anorectal manometry remains the gold standard for assessing bowel muscle function and guiding effective treatment.
