Unilateral versus bilateral adnexal disease in stage III and stage IV endometriosis does not affect pregnancy outcome after operative laparoscopy

Safety and efficacy of two techniques of temporary ovarian suspension to the anterior abdominal wall after operative laparoscopy

BACKGROUND

This retrospective study compares the safety and efficacy of temporary ovarian suspension (TOS) to the anterior abdominal wall using absorbable versus non-absorbable suture after operative laparoscopy to elevate the ovaries away from the ovarian fossa to reduce postoperative adhesion development.

METHODS

Patients (n=152) underwent TOS to the anterior abdominal wall at the conclusion of surgery between 1998 and 2017. One hundred forty-two patients underwent operative laparoscopy for advanced stages of endometriosis (93.4%) and 10 patients for other indications (6.6%). In 78 patients the ovaries were suspended to the fascia using absorbable 3-0 plain catgut sutures (Group 1). In 74 earlier patients non-absorbable 3-0 mono-lamentous nylon was used to suspend the ovaries to the anterior abdominal (Group 2).

RESULTS

In both groups there was no reported incidence of any major intra-operative complications such as bleeding, or late complications such as infection, hematoma or bowel herniation through the suture loop and its sequalae (bowel obstruction or strangulation). In all patients in both groups the ovaries were present in its anatomical location on transvaginal ultrasound scan, one week after surgery following absorption or removal of the TOS suture. There was no significant difference in clinical pregnancy (34.3% vs 44.2%) and delivery (31.3% vs 36.5%) rates in patients who conceived with non-IVF methods between Group 1 and Group 2 respectively.

CONCLUSIONS

TOS to the anterior abdominal wall, using absorbable or non-absorbable sutures, in an attempt to reduce postoperative adhesion development between the ovary and ovarian fossa, is simple, safe, easy to learn, and has potential effectiveness.

Pregnancy Rates after Intrauterine Insemination in Moderate to Severe Endometriosis: A Systematic Review and Meta-analysis of Observational Studies

To evaluate the efficacy and safety of intrauterine insemination (IUI) in moderate to severe endometriosis patients, a systematic review and meta-analysis was conducted since the role of this treatment strategy in these patients is a matter of debate in the literature. Systematic searches were performed in PubMed, EMBASE, Cinahl, and The Cochrane Library from inception to September 1, 2016. Studies including moderate to severe endometriosis patients reporting pregnancy rates after IUI were selected. The primary outcome was live birth after IUI treatment compared to expectant management. Secondary noncomparative outcomes were live birth and clinical pregnancy, which were presented as weighed mean pregnancy rates. Nineteen articles (2 unclear design, 11 retrospective, 6 prospective) were included for the analysis. Our primary outcome measure was only addressed by one study, showing an odds ratio of 1.77 (95% confidence interval [CI], 0.86–3.63) on live birth favoring IUI versus no treatment. The calculated weighed mean live birth and clinical pregnancy rate per patient was 20.3% (95% CI, 11.2–29.4) and 32.7% (95% CI, 21.3– 44.0), respectively. This meta-analysis of observational data showed that IUI could be a feasible treatment in moderate to severe endometriosis. Whether this treatment should be structurally offered prior to in vitro fertilization needs to be investigated in a randomized, controlled trial, including time-to-pregnancy, safety, and cost-effectiveness.

Impact of endometriosis and its staging on assisted reproduction outcome: systematic review and meta-analysis

OBJECTIVE

To evaluate whether the presence or severity of endometriosis affects the outcome of assisted reproductive techniques (ART).

METHODS

In this systematic review, all studies comparing the outcome of ART in women with and those without endometriosis, or at different stages of the disease, were considered eligible. We used either risk ratio (RR) or mean difference (MD) and their 95%CIs for comparisons. The primary outcome was live birth; the secondary outcome was clinical pregnancy. Miscarriage and the number of oocytes retrieved were examined as additional outcomes.

RESULTS

We included 92 studies in the review and 78 in the meta-analysis: 20,167 women with endometriosis were compared with 121,931 women without endometriosis, and 1703 women with Stage-III/IV endometriosis were compared with 2227 women with Stage-I/II endometriosis. The following results were observed for the comparison of women with endometriosis vs women without endometriosis: live birth, RR = 0.99 (95%CI, 0.92-1.06); clinical pregnancy, RR = 0.95 (95%CI, 0.89-1.02); miscarriage, RR = 1.31 (95%CI, 1.07-1.59); number of oocytes retrieved, MD = -1.56 (95%CI, -2.05 to -1.08). The following results were observed for the comparison of women with Stage-III/IV vs Stage-I/II endometriosis: live birth, RR = 0.94 (95%CI, 0.80-1.11); clinical pregnancy, RR = 0.90 (95%CI, 0.82-1.00); miscarriage, RR = 0.99 (95%CI, 0.73-1.36); number of oocytes retrieved, MD = -1.03 (95%CI, -1.67 to -0.39).

CONCLUSIONS

Women with endometriosis undergoing ART have practically the same chance of achieving clinical pregnancy and live birth as do women with other causes of infertility. No relevant difference was observed in the chance of achieving clinical pregnancy and live birth following ART when comparing Stage-III/IV with Stage-I/II endometriosis. The quality of the evidence for the additional examined outcomes was very low, not allowing meaningful conclusions to be drawn.
