Consensus definitions and interpretation templates for dynamic ultrasound imaging of defecatory pelvic floor disorders: Proceedings of the consensus meeting of the pelvic floor disorders consortium of the american society of colon and rectal surgeons, the society of abdominal radiology, the international continence society, the American urogynecologic society, the international urogynecological association, and the society of gynecologic surgeons

APFUS = endoanal/endorectal pelvic floor ultrasound; EAS = external anal sphincter; IAS = internal anal sphincter Important caveats in the imaging include the following: 1) identification of the puborectalis muscles immediately cephalad to the anal sphincter; 2) differentiation of an anterior external sphincter injury versus a short anal sphincter in a female in the middle anal canal; 3) recognition that the distal anal canal only contains external sphincter; and 4) and a thinned out perineal body may be a sign of middle anal sphincter injury.
