The Division of Colon and Rectal Surgery at Mount Sinai St. Luke’s Roosevelt Hospital runs Manhattan’s only full service, state of the art anorectal physiology lab dedicated to the evaluation and management of patients with functional bowel disorders such as fecal incontinence and severe constipation. Anorectal manometry, trans-rectal ultrasonography and pudendal nerve testing are all performed in an office setting. If needed, additional studies such as cinedefecography and colonic transit studies are coordinated through the lab.
ANORECTAL MANOMETRY measures your anal sphincter pressures as well as the ability of the sphincter to sense rectal contents. It is a painless test that is performed with a small water-perfused catheter that is placed into the rectum. Preparation for the test is with a Fleets enema the morning of your procedure.
TRANS-RECTAL ULTRASONOGRAPHY is performed for one of two reasons. If you have been diagnosed with a rectal tumor, a transrectal sonogram is performed as part of the staging of your condition and will likely help your physician determine a course of management. Alternatively, transrectal sonography is used in patients that are having problems with control of their bowels as this is an excellent way to image the anal sphincter complex and determine if there is any damage to these muscles. The test is performed by placing a probe roughly the size of a finger into the anus. No radiation is used and the test is painless. Preparation for the test is with a Fleets enema the morning of your procedure.
PUDENDAL NERVE TESTING is performed to test the integrity of the nerves to the sphincter muscles. This is performed with the physician’s index finger placed into the rectum and “stimulating” the nerves. The test may be uncomfortable due to some pressure created by the physician’s examining finger inside the rectum. Preparation for the test is with a Fleets enema the morning of your procedure.
