Endoanal ultrasound

Endoanal ultrasound
Purposeimages structures of anal canal

Endoanal ultrasound is a type of medical investigation which uses ultrasonography to show images of the structures of the anal canal.[1] It is used in the investigation of some anorectal symptoms, e.g. fecal incontinence or obstructed defecation.[2]

Endorectal ultrasound is a similar investigation but the ultrasound probe is used to image the rectum and surrounding tissues. It is used to image lesions in the rectum, for example a tumor caused by colorectal cancer and to assess local lymph node involvement.[3][4]
