To evaluate the assisted reproductive technology (ART) cumulative live-birth rate (LBR) in a cohort of bowel endometriosis patients with no prior history of surgery for endometriosis.
Prospective cohort study.
One hundred and one consecutive infertile bowel-endometriosis patients with no prior history of surgery for endometriosis in whom the diagnosis of endometriosis was based on published imaging criteria using transvaginal sonography and magnetic resonance imaging.
Main Outcome Measure(s)
Cumulative LBR, with statistical analysis via Kaplan Meier method with a “conservative” method, whereby it was assumed that no live births took place for patients who did not return.
Between January 2016 and December 2018, 101 bowel endometriosis patients underwent 176 ART cycles. The mean number of deep-infiltrating endometriosis lesions per patient was 3 ± 0.9, with a mean number of bowel lesions of 1.3 ± 0.6. Seventy-three percent of the patients had associated endometriomas, and 88.1% had associated adenomyosis. Overall, the cumulative LBR after four ART cycles was 64.4%, using the conservative Kaplan-Meier method.
The ART cumulative LBR was very satisfactory (64.4%) in bowel endometriosis patients with no prior history of surgery for endometriosis. In light of these data, clinicians should carefully weigh the pros and cons before systematically referring infertile bowel endometriosis patients to fertility-preserving surgery because as first-line ART appears to offer satisfactory results.
