Digital Manometry (DM): A Novel, Inexpensive Diagnostic Tool for Anorectal Disorders

Dr. William Chey has developed an inexpensive, point-of-service device, Digital Manometry (DM), that can provide a detailed assessment of anorectal function in anorectal disorders. 

Dr. William Chey, in conjunction with UM Biomedical Engineering, has developed an inexpensive, point-of-service device called Digital Manometry (DM) that can provide a detailed assessment of anorectal function in anorectal disorders including fecal incontinence (FI) and chronic constipation due to dyssynergic defecation (DD). As a lower cost, and easy to use device, DM will enable physicians to perform these tests in an office setting. Results from DM will allow providers to better understand the cause and thus, the most appropriate treatment of a patient’s fecal incontinence. DM also provides the opportunity to dramatically expand the number of rectal manometry tests performed each year. In early human clinical studies exploring the use of DM for dyssynergic defecation, DM has been found to provide comparable and even incremental information when compared to standard laboratory based anorectal manometry.
