Abstract Objective To show the correlation of anorectal electromanometry and three-dimensional anorectal ultrasonography in patients with fecal incontinence. Method Prospective study involving 34 women (mean age: 55 years) with a diagnosis of fecal incontinence. The samples were submitted to three-dimensional anorectal ultrasonography/Echodefecography and anorectal electromanometry. Results Based on anorectal electromanometry data, 70.5% of 34 patients had hypotonia at rest, 64.7% had hypotonic contraction, 52.9% had both hypotonia at rest and hypotonic contraction, and 44.1% had anismus. By three-dimensional anorectal ultrasonography, 32.3% had internal anal sphincter injury, 79.4% had external anal sphincter injures, and 26.4% had both internal and external anal sphincter injuries. In 38.2%, anismus was suggested and 50% showed rectocele. Overall, only 5.8% had normal results for anorectal electromanometry combined with three-dimensional anorectal ultrasonography. Kappa index was 0.297 and the presence of anismus through anorectal electromanometry and three-dimensional anorectal ultrasonography was compared by Student's t test application, with p < 0.0001. Conclusion We conclude that there was a reasonable agreement in the comparison of sphincter hypotonia by anorectal manometry and sphincter injury by anorectal three-dimensional ultrasonography in a group of patients with fecal incontinence. The incidence of anismus in patients with fecal incontinence is considerable, and the therapeutic approach in these patients should be modified.
