First-line in vitro fertilization or surgery for infertile women with bowel endometriosis?

Impact of surgery on reproductive outcomes in women with deep endometriosis and proven presurgical infertility: Facts and controversies

In women with proven infertility and deep endometriosis (DE), optimal management is controversial. To date, there is no clear evidence on the association between infertility and different stages of rASRM, nor is there clear guidance from leading scientific societies for surgical treatment of DE patients. A comprehensive literature search was conducted on the main databases for English-language trials describing the effectiveness of surgery for DE in patients with proven infertility; 16 studies were deemed eligible for inclusion in this systematic review (CRD42024498888). Quantitative analysis was not possible because of the heterogeneity of the data. A descriptive summary of the results according to location of pathology, surgical technique used, and whether assisted reproductive technology (ART) was needed or not was provided. A total of 947 infertile women were identified, 486 of whom became pregnant, with an average pregnancy rate of 51.3%. Our review suggests that surgery can be of valuable help in improving reproductive outcomes by improving the results of ART. It has not been possible to reach robust conclusions on the outcomes of surgery based on the location of DE because of the heterogeneity of evidence available to date. Overall, although some data encourage first-line surgical management, further investigation is needed to determine its effective application before or after ART failure.

Deep Endometriosis and Infertility: What Is the Impact of Surgery?

In women with deep endometriosis, the spontaneous fertility rate might range from 2 to 10%. The optimal management of these women is still an area of debate. Therefore, this review aims to explore the literature on the impact of deep endometriosis surgery on reproductive outcomes and pregnancy rates in women with and without prior infertility. A total of 392 articles were identified through database searching. Twenty-three studies were eligible to be included in the review. A total of 1548 women were identified, 814 of whom became pregnant, with a mean pregnancy rate of 52.6% (95% CI 49.7-63%). Our review suggests that surgery may improve fertility outcomes. Due to the variability in the studies, it is impossible to stratify fertility outcomes of surgery by the localization of deep endometriosis. More investigations are needed to determine whether surgical management should be first-intention or limited to the failure of medically assisted reproduction treatment.

Long term outcomes following surgical management of rectal endometriosis: 7-year follow-up of patients enrolled in a randomized trial

STUDY OBJECTIVE

To compare functional outcomes, recurrence rate and pregnancy likelihood in patients undergoing conservative or radical surgery in patients with deep rectal endometriosis 7 years post-operatively.

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

55 patients with deep endometriosis infiltrating the rectum.

INTERVENTIONS

Patients underwent either segmental resection or nodule excision by shaving or disc excision, depending on a randomization which was performed preoperatively using sequentially numbered, opaque sealed envelopes.

MEASUREMENT AND MAIN RESULTS

The primary endpoint was the number of patients experiencing one of the following symptoms: constipation, frequent bowel movements, anal incontinence or bladder dysfunction 24 months postoperatively. Secondary endpoints were values of gastrointestinal and overall quality of life scores. The 7 year-recurrence rates (new deep endometriosis nodule infiltrating the rectum) in the excision vs. the segmental resection arms were 7.4 % vs. 0% (P=.24). One of more symptoms included in the definition of the primary outcomes were recorded in 55.6% vs. 60.7% of patients (P=0.79). 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 differences between the two groups 7 years postoperatively. At the end of the 7-year study period, 31 of the 37 patients who tried to conceive were successful (83.8%) including: 27 (57.4%) natural conceptions and 20 (42.6%) pregnancies resulting from ART procedures. Pregnancy rate was 82.4% vs. 85% in the two arms (P=.99). A 75.7% live birth rate was recorded. At the end of the follow up there were 15 women with one child (40.5%) and 13 women with 2 children (35.1%). During the 7-year follow- up, the reoperation rate was respectively 37% and 35.7% in each arm, P=0.84). Among the 27 reoperation procedures during the follow up period, 11 were postoperative complications (40.7%), 7 were necessary prior to ART management (25.9%), 8 were for recurrent abdominal or pelvic pain (29.6%) and one for midline ventral hernia following pregnancy (3.7%).

CONCLUSIONS

Our study did not reveal a significant difference in terms of digestive functional outcomes, recurrence rate, reoperation risk and pregnancy likelihood when conservative and radical rectal surgery for deep endometriosis were compared 7 years postoperatively. Postoperative pregnancy rate observed in our series is high.
