Study No. 7: Role of puborectalis muscle in anal continence. Comments on original 4D pelvic ultrasound data from Chantarasorn & Dietz

Abstract: External 4D ultrasound data from Chantrasorn and Dietz demonstrating no relationship between fecal incontinence and avulsion of
the puborectalis was used to challenge the Theory’s prediction of puborectalis function. The results were consistent with the Theory’s hypothesis that the role of puborectalis may be more to immobilize the anorectum than create primary closure per se.
