Anorectal manometry is a diagnostic procedure used to evaluate the function of the muscles and nerves in the rectum and anus. During this test, a small, thin manometry probe equipped with multiple microsensors and a small balloon is carefully inserted into the rectum. This probe is connected to a computerized device that captures and records the activity of the muscles and nerves in the anorectal area. As part of the procedure, the balloon is inflated with small amounts of air and then deflated multiple times, allowing the physician to assess the muscle responses and overall function of the anorectal region. This test is particularly useful in diagnosing conditions related to bowel control, such as fecal incontinence or constipation. Once the test is completed, the manometry probe, along with the attached sensors and balloon, is gently removed from the rectum, concluding the procedure.
