Brief Summary:
To goal of this study is to determine whether laparoscopic resection of colorectal endometriosis results in an increased cumulative live birth rate (CLBR) both spontaneous and after ART (including in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), and better patient reported outcome measures (PROMs) compared to an IVF/ICSI treatment trajectory.
Detailed Description:
Endometriosis is characterized by extra-uterine endometrium like tissue and affects 10-15% of the women in their reproductive years and in 5-12% of these women colorectal endometriosis is present. The quality of life is lowered due to severe pain symptoms (dysmenorrhea, dyschezia, dysuria, chronic pelvic pain) and subfertility.The management of colorectal endometriosis-related subfertility is challenging. While the impact of colorectal endometriosis per se remains inconclusive as other intraperitoneal endometriosis lesions are frequently present, fertility is most likely affected by multiple mechanisms including inflammatory alterations in peritoneal fluid, alterations in estrogen and progesterone hormone levels, lowered endometrium receptivity, associated adenomyosis, a lower ovarian reserve (in case endometriomas are present) and adhesion formation that disrupts adnexal anatomy and function. Usually, surgery is preferred in case of dominant pain complaints, while IVF/ICSI is started when the wish to conceive is dominant. Recent evidence suggests a CLBR of 44.9% in patients with rectosigmoid endometriosis treated by surgery compared to 55.9% after 4 cycles of IVF/ICSI treatment without surgery. In the Netherlands, the number of reimbursed IV/ICSI attempts in limited to three. In addition, a combined strategy may result in even higher cumulative live birth rates. However, the place and optimal timing of surgery in patients with colorectal endometriosis and a desire to have children is unknown.
To provide robust evidence that can be extrapolated to the Dutch healthcare system, this study aims to determine whether surgical excision of colorectal endometriosis results in increased CLBR both spontaneous and after IVF/ICSI, and better PROMs compared to an IVF/ICSI treatment trajectory.
