Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).
