Abstract
BackgroundPurpose of the study is to define the role of conventional radiology and MRI in the evaluation of pelvic floor hernias in female pelvic floor disorders.MethodsA MEDLINE and PubMed search was performed for journals before March 2013 with MeSH major terms 'MR Defecography' and 'pelvic floor hernias'.ResultsThe prevalence of pelvic floor hernias at conventional radiology was higher if compared with that at MRI. Concerning the hernia content, there were significantly more enteroceles and sigmoidoceles on conventional radiology than on MRI, whereas, in relation to the hernia development modalities, the prevalence of elytroceles, edroceles, and Douglas' hernias at conventional radiology was significantly higher than that at MRI.ConclusionsMRI shows lower sensitivity than conventional radiology in the detection of pelvic floor hernias development. The less-invasive MRI may have a role in a better evaluation of the entire pelvic anatomy and pelvic organ interaction especially in patients with multicompartmental defects, planned for surgery.
Highlights
Pelvic floor disorders represent a significant cause of morbidity and reduction in quality of life that appear to be increasing in frequency during the last few years [1]
Pelvic floor disorders may be associated, with an incidence ranging from 18% to 45%, to the so-called midline pelvic floor sagittal hernias (MPH) that represent the herniation of the peritoneum and/or peritoneal viscera in the Douglas’, Retzius’, and retrorectal spaces
In our experience, the specificity of MRI versus conventional radiology is of a 100%; the sensibility of MR-D in the detection of an omentocele, sigmoidocele, and enterocele is, respectively, 95%, 82%, and 65%, showing an inferior diagnostic capacity if compared with conventional radiology [29,30]
Summary
Concerning the hernia content, there were significantly more enteroceles and sigmoidoceles on conventional radiology than on MRI, whereas, in relation to the hernia development modalities, the prevalence of elytroceles, edroceles, and Douglas’ hernias at conventional radiology was significantly higher than that at MRI
