Endometriotic Parietal Involvement of the Rectosigmoid Clinical Trial
Official title:
Endometriosis of the Recto-sigmoid: MRI Criteria Predictive of Shaving or Segmental Resection
Evaluate MRI criteria predictive of the type of surgery to be performed for an "in sano" resection of endometriotic involvement of the recto-sigmoid by a resection without opening of the rectal mucosa ("shaving") versus a segmental resection.
PURPOSE: To retrospectively determine the accuracy of MRI rectal and pararectal signs in
predicting a segmental resection of lesions located in the rectum until the recto-sigmoid
junction.
MATERIALS AND METHODS: Institutional review board approval for this study was obtained and
waived written informed consent. The MR images of 61 patients treated for rectal
endometriosis over a 6 years period were reviewed. Two blinded readers performed in consensus
a systematic analysis of 7 rectal (length, transverse axis, thickness and circumference of
the lesion, and presence of a convex base, submucosal edema and hyperintense cystic areas)
and 4 pararectal (posterior vaginal fornix, parametrial, ureteral and sacro-recto-genital
septum involvements) signs for each lesion. MR imaging results were compared with surgical
procedure (shaving versus segmental resection). Efficacy parameters were calculated with 95 %
confidence intervals (CIs).
