title: Diagnosing enteroceles using dynamic magnetic resonance imaging.
abstract: OBJECTIVE
  Enteroceles are in part difficult to detect but a frequent finding in pelvic floor disorders. The aim of this study was to evaluate magnetic resonance colpocystorectography in the diagnosis of enteroceles.
  
  
  METHODS
  In this prospective study 11 volunteers and 55 patients with pelvic floor descent were examined. In addition to magnetic resonance colpocystorectography, a dynamic cystoproctography was performed on 34 patients. Opacification of organs was used. An enterocele was assessed in relationship to the pubococcygeal reference line (magnetic resonance colpocystorectography) or the width of the rectovaginal space (dynamic cystoproctography). A clinical gynecologic examination served as reference.
  
  
  RESULTS
  The clinical examination diagnosed an enterocele in 43, magnetic resonance colpocystorectography in 49, and dynamic cystoproctography in 14 cases. Magnetic resonance colpocystorectography further subdivided the enteroceles according to their contents (mesenteric fat or fluid, 12; small bowel, 32, large bowel, 3; and rectosigmoidocele, 2). Magnetic resonance colpocystorectography proved statistically significantly superior to dynamic cystoproctography (15 cases) and the reference. Sensitivity and specificity of magnetic resonance colpocystorectography were 100 percent each. It was able to reveal clinically missed enteroceles as being peritoneoceles associated with a rectocele or a uterovaginal prolapse (10 cases).
  
  
  CONCLUSIONS
  Magnetic resonance colpocystorectography is a promising method for diagnosis of enteroceles, because hernial canal, sac, and contents are reliably identified.
