Results of endosonographic imaging of the anal sphincter 2–7 days after primary repair of third‐ or fourth‐degree obstetric sphincter tears

Abstract

Most women (90%) with a clinical third- or fourth-degree obstetric sphincter tear have endosonographic sphincter defects if they are examined 2-7 days after primary repair. The extent of the endosonographic defects seems to be determined mainly by the surgical experience of the doctor performing the repair, and not by the clinical degree of the tear.
