Study Objective: To compare functional outcomes, recurrence rate, and pregnancy likelihood in patients undergoing conservative or radical surgery for deep rectal endometriosis followed up for 7 years., Design: Prospective study in a cohort of patients enrolled in a 2-arm randomized trial from March 2011 to August 2013., Setting: A tertiary referral center., Patients: Fifty-five patients with deep endometriosis infiltrating the rectum., Interventions: Patients underwent either segmental resection or nodule excision via shaving or disk excision, depending on randomization that was performed preoperatively using sequentially numbered, opaque sealed envelopes., Measurements and Main Results: The primary end point was the number of patients experiencing one of the following symptoms: constipation, frequent bowel movements, anal incontinence, or bladder dysfunction 24 months after surgery. The secondary end points were values of gastrointestinal and overall quality of life scores. The 7-year recurrence rates (new deep endometriosis nodules infiltrating the rectum) in the excision vs segmental resection arms were 7.4 % vs 0% (p = .24). One of the symptoms included in the definition of the primary outcomes was recorded in 55.6% vs 60.7% of patients (p = .79). However, 51.9% vs 53.6% of patients considered their bowel movements as normal (p = .99). An intention-to-treat comparison of overall quality of life scores did not find a difference between the 2 groups 7 years after surgery. At the end of the 7-year study period, 31 of 37 patients who tried to conceive were successful (83.8%), including 27 pregnancies (57.4%) resulting from natural conception and 20 pregnancies (42.6%) resulting from assisted reproductive technology procedures. The pregnancy rate was 82.4% vs 85% in the 2 arms (p = .99). A 75.7% live birth rate was recorded. At the end of the follow-up, there were 15 women with 1 child (40.5%) and 13 women with 2 children (35.1%). During the 7-year follow-up, the reoperation rates were 37% and 35.7%, respectively, in each arm (p = .84). Among the 27 reoperation procedures during the follow-up period, 11 (40.7%) were for postoperative complications, 7 (25.9%) were necessary before assisted reproductive technology management, 8 (29.6%) were for recurrent abdominal or pelvic pain, and 1 (3.7%) was for midline ventral hernia after pregnancy., Conclusion: Our study did not reveal a considerable difference in terms of digestive functional outcomes, recurrence rate, reoperation risk, and pregnancy likelihood when conservative and radical rectal surgeries for deep endometriosis were compared 7 years after surgery. The postoperative pregnancy rate observed in our series was high., (Copyright © 2022 AAGL. Published by Elsevier Inc. All rights reserved.)

Aim: The aim of this work was to assess whether placement of a biological mesh (Permacol ® ) between the vaginal and rectal sutures reduces the rate of rectovaginal fistula in patients with deep rectovaginal endometriosis., Method: We report a retrospective, comparative study enrolling patients with vaginal infiltration of more than 3 cm in diameter and rectal involvement in two centres. They benefited from complete excision of rectovaginal endometriotic nodules with or without a biological mesh placed between the vaginal and rectal sutures. The rate of rectovaginal fistula was compared between the two groups., Results: Two hundred and nine patients were enrolled: 42 patients underwent interposition of biological mesh (cases) and 167 did not (controls). Ninety-two per cent of cases and 86.2% of controls had rectal infiltration more than 3 cm in diameter. Cases underwent rectal disc excision more frequently (64.3% vs. 49.1%) and had a smaller distance between the rectal staple line and the anal verge (4.4 ± 1.4 cm vs. 6 ± 2.9 cm). Rectovaginal fistulas occurred in 4 cases (9.5%) and 12 controls (7.2%). Logistic regression analyses revealed no difference in the rate of rectovaginal fistula following the use of mesh (adjusted OR 1.6, 95% CI 0.3-9.5). A distance of less than 7 cm between the rectal staple line and the anal verge was found to be an independent risk factor for the development of rectovaginal fistula (adjusted OR 15.1, 95% CI 1.7-132)., Conclusion: Our results suggest that the placement of a biological mesh between the vagina and rectal sutures may not affect the rate of formation of postoperative rectovaginal fistula following excision of deep infiltrating rectovaginal endometriosis., (© 2021 The Association of Coloproctology of Great Britain and Ireland.)

Study Question: Is there a difference in functional outcomes and recurrence rate between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 5 years postoperatively?, Summary Answer: No evidence was found that long-term outcomes differed when nodule excision was compared to rectal resection for deeply invasive endometriosis involving the bowel., What Is Known Already: Functional outcomes of nodule excision and rectal resection for deeply invasive endometriosis involving the bowel are comparable 2 years after surgery. Despite numerous previously reported case series enrolling patients managed for colorectal endometriosis, long-term data remain scarce in the literature., Study Design, Size, Duration: From March 2011 to August 2013, we performed a two-arm randomized trial, enrolling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring >20 mm in length, involving at least the muscular layer in depth, and up to 50% of rectal circumference. Among them, 55 women were enrolled at one tertial referral centre in endometriosis, using a randomization list drawn up separately for this centre. Institute review board approval was obtained to continue follow-up to 10 years postoperatively. One patient requested to stop the follow-up 2 years after surgery., Participants/materials, Setting, Methods: Patients underwent either nodule excision by shaving or disc excision, or segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of randomization results. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (≥3 stools/day), anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were values taken from the Knowles-Eccersley-Scott-symptom questionnaire (KESS), the gastrointestinal quality of life index (GIQLI), the Wexner scale, the urinary symptom profile (USP) and the Short Form 36 Health Survey (SF36)., Main Results and the Role of Chance: Fifty-five patients were enrolled. Among the 27 patients in the excision arm, two were converted to segmental resection (7.4%). One patient managed by segmental resection withdrew from the study 2 years postoperatively, presuming that associated pain of other aetiologies may have jeopardized the outcomes. The 5 year-recurrence rate for excision and resection was 3.7% versus 0% (P = 1), respectively. For excision and resection, the primary endpoint was present in 44.4% versus 60.7% of patients (P = 0.29), respectively, while 55.6% versus 53.6% of patients subjectively reported normal bowel movements (P = 1). An intention-to-treat comparison of overall KESS, GIQLI, Wexner, USP and SF36 scores did not reveal significant differences between the two arms 5 years postoperatively. Statistically significant improvement was observed shortly after surgery with no further improvement or impairment recorded 1-5 years postoperatively. During the 5-year follow-up, additional surgical procedures were performed in 25.9% versus 28.6% of patients who had undergone excision or resection (P = 0.80), respectively., Limitations, Reasons for Caution: The presumption of a 40% difference concerning postoperative functional outcomes in favour of nodule excision resulted in a lack of power for demonstration of the primary endpoint difference., Wider Implications of the Findings: Five-year follow-up data do not show statistically significant differences between conservative and radical rectal surgery for long-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum., Study Funding/competing Interest(s): No specific funding was received. Patient enrolment and follow-up until 2 years postoperatively was supported by a grant from the clinical research programme for hospitals in France.
