Entero-colpo-defecography vs supine entero-MRI: which one is the best tool in the differentiation of enterocele, elytrocele and edrocele?

Pelvic floor disorders represent a significant cause of morbidity associated with a severe reduction of quality of life. It represents a very common clinical problem that afflicts women three to seven time more often than men. The purpose of this study was to assess the diagnostic tools available to define the imaging strategy in patients with pelvic floor dynamic dysfunctions and to investigate their abilities in the diagnosis of enterocele, elytrocele and edrocele. From January 2008 to May 2011, 614 patients with symptoms related to pelvic floor dynamic dysfunctions were enrolled in our retrospective study. After anamnesis and clinical examination, entero-colpo-defecography (ECD) and supine entero-magnetic resonance (SE-MR) exams were performed in all patients. This study showed that the diagnostic efficacy of ECD is higher than that of SE-MR in the detection of enterocele and edrocele. Furthermore, elytrocele can be visualized only with ECD considering the position of patient during SE-MR examination. In addition, in patients planned for surgery, SE-MR is more useful to clarify the intra-pelvic interaction of multiple organ prolapse and to better define the pelvic anatomy and functioning.
