Brief Summary
The purpose of this study is to determine whether performing colorectal resection in deep endometriosis infiltrating the rectum is responsible for a higher rate of postoperative digestive and urinary dysfunction when compared to rectal nodules excision (conservation of the rectum).

Eligibility Criteria
You may qualify if:
- female
- age \>18 and \<45
- at least one digestive symptom related to deep endometriosis (pain defecation, either cyclic diarrhea or cyclic constipation, cyclic rectorrhagia)
- preoperative work up revealing a deep endometriosis nodule infiltrating the rectum (either muscular or submucosal layer, on less than 50% of rectal circumference) and measuring at least 20 mm
- affiliation to the National Social Security System
You may not qualify if:
- pregnant women or likely to be at the moment of the surgery
- no preoperative hypothesis of rectal involvement
- no intraoperative confirmation of the rectal involvement
- advanced rectal endometriosis involving rectal mucosa or more than 50% of the rectal circumference (preoperative assessment using rectal endoscopy or ultrasonography)
- women unable to give an informed consent (guardianship or trusteeship)
