University Hospital, Rouen
  Purpose
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).

Condition Intervention
Endometriosis, Rectum Procedure: Rectal/colorectal segmental resection Procedure: Rectal nodule excision

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Trial Comparing Digestive and Urinary Dysfunction Secondary to 2 Surgical Techniques Used in the Management of Deep Endometriosis Infiltrating the Rectum: Colorectal Resection and Rectal Nodules Excision (ENDORE)

    • major constipation (< 1 stool/5 days) associated with defecation pain;
    • increase of the stool frequency ( >=3 stools/day);
    • anal incontinence;
    • de novo postoperative dysuria confirmed by urodynamic work up;
    • bladder atony requiring daily catheterization.


Secondary Outcome Measures:
  • Percentage of women experiencing postoperative pain related to endometriosis [ Time Frame: 24 months ]
    Percentage of women presenting with dysmenorrhea, dyspareunia, chronic pelvic pain

  • Percentage of women experiencing a postoperative digestive or urinary dysfunction [ Time Frame: 12 months ]

    At least one of following symptoms:

    • major constipation (< 1 stool/5 days) associated with defecation pain;
    • increase of the stool frequency ( >=3 stools/day);
    • anal incontinence;
    • de novo postoperative dysuria confirmed by urodynamic work up;
    • bladder atony requiring daily catheterization.

  • Biberoglu & Behrman score [ Time Frame: 24 months ]
    Evaluation of endometriosis related pain using the above mentioned scale

  • SF-36 quality of life scale [ Time Frame: 24 months ]
  • The Gastrointestinal Quality of Life Index (GIQLI) [ Time Frame: 24 months ]
  • The Knowles-Eccersley-Scott-Symptom Questionnaire (KESS) [ Time Frame: 24 months ]
  • Wexner questionnaire related to anal incontinence [ Time Frame: 24 months ]
  • percentage of women requiring endoscopic dilatation due to the stenosis of the colorectal anastomosis [ Time Frame: 24 months ]

Estimated Enrollment: 60
Study Start Date: March 2011
Estimated Study Completion Date: September 2023
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Rectal/colorectal segmental resection Procedure: Rectal/colorectal segmental resection
Resection of the rectum +/- sigmoid colon involved by the deep infiltrating endometriosis
Other Name: Anterior rectal resection
Active Comparator: Rectal nodule excision Procedure: Rectal nodule excision
Either full thickness excision or rectal shaving
Other Name: Conservative sergery of the rectum

Detailed Description:

The study compare digestive and urinary functional outcomes following surgical management of rectal endometriosis by either colorectal resection or conservative surgery (shaving or full thickness excision of rectal nodules).

Patients managed for rectal endometriosis are randomized in two arms, and followed up for 24 months. The assessment of digestive and urinary functions is performed at 6, 12, 18 and 24 months using standardized questionnaires. Postoperative complications and improvement of endometriosis related pain are also recorded.
