|Endometriotic Parietal Involvement of the Rectosigmoid||Other: MRI|
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).

- Other: MRI
MRI protocol associating sagittal and axial (+/- coronal) sequences in T2 + / - turbo spin T1 weighting with fat saturation.
- Comparison of MRI data with intraoperative data and anatomopathology [ Time Frame: Intraoperatively ]MRI criteria of parietal involvement will be confronted with the type of surgery performed (shaving or segmental resection) A rectosigmoid parietal involvement will be defined by the nodular replacement of the normal signal of the digestive muscularis, on at least two planes of cuts or two different weightings.
