Here we discuss the role of endoanal ultrasound (US) scanning in fecal incontinence. Two-dimensional (2-D) US demonstrates precisely the type and extent of muscle injuries in relation to the anal circumference, whereas 3-D scanning shows it in relation to anal canal length. Interpretation of 3-D imaging is simpler, as muscle length can also be measured longitudinally. The exact identification of the injured muscles is important in deciding upon the best therapeutic option. Anal US can also be useful in evaluating the results of surgical repair, identifying adjacent or overlapping muscles, and documenting persisting muscle injury.
