BACKGROUND: There is currently no consensus about indications for surgery for infertility associated with colorectal endometriosis. The aim of this study was to evaluate cumulative pregnancy rates (CPRs) after ICSI-IVF cycles in patients wi…

STUDY QUESTION: How is the expression of nectins and nectin-like molecules (Necls) detected by immunostaining altered by endometriosis? SUMMARY ANSWER: Our results suggest that Nectin-1, -3, -4 and Necl-2 may contribute to the pathogenesis…

L’endometriose se definit par la presence de tissu endometrial (glandes et stroma) en dehors de la cavite uterine. Il s’agit d’une pathologie benigne touchant 3% de la population generale et environ 10% des femmes en âge de procreer (1). So…

STUDY OBJECTIVE: To evaluate urologic complications after colorectal resection for endometriosis. DESIGN: Cohort study (Canadian Task Force classification II-2). SETTING: Tertiary referral university hospital and expert center in endometr…

BACKGROUND: To evaluate prolapse-related symptoms, quality of life and sexuality of patients with validated questionnaires before and after surgery for genital prolapse and assess relevance of such an evaluation to select women for surgery.…

Endometriosis is usually described as a complex multifactorial disease involving dysregulation of estrogen metabolism, inflammatory and immunological mechanisms. Recently, many authors have questioned the environmental pollution and toxins …

Colorectal surgery for endometriosis is increasingly performed, but its assessment is still incomplete, especially regarding its impact on quality of life, the recurrence rate and subsequent fertility. Segmental resection is the technique m…

STUDY QUESTION: What is the accuracy of magnetic resonance imaging (MRI) in the diagnosis of parametrial endometriosis in comparison with surgicopathological findings? SUMMARY ANSWER: MRI displayed an accuracy of 96.4% in the preoperative …

OBJECTIVE: To evaluate the cumulative pregnancy rate (CPR) per patient after in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) cycles in patients with endometriomas and to evaluate the determinant factors of CPR per patient…

OBJECTIVES: To determine the value of postcontrast MR imaging (MRI) in cases of suspected pelvic endometriosis by assessing interobserver variability of MR imaging according to the endometriotic locations. METHODS: This retrospective study…

OBJECTIVE: To determine whether the surgical route of colorectal resection for endometriosis is a determinant factor for fertility. DESIGN: Prospective study. SETTING: Tertiary-care university hospital. PATIENT(S): Fifty-two patients wit…

A specific statistical tool (the cumulative summation test for learning curve or LC-CUSUM) was used to monitor the learning curve of four trainees for the diagnosis of endometriomas by transvaginal ultrasound. A large intertrainee variabili…

BACKGROUND: Although several scoring systems have been published to evaluate the pregnancy rate after ICSI-IVF in infertile patients, none of them are applicable for patients with deep infiltrating endometriosis (DIE) nor can they evaluate …

OBJECTIVE: To evaluate urinary symptoms before and after colorectal resection for endometriosis using validated questionnaires. STUDY DESIGN: We randomly assigned 52 patients with colorectal endometriosis to undergo laparoscopically assist…

OBJECTIVE: The aims of this prospective study were to evaluate fertility, pregnancy outcomes and their determinant factors after laparoscopic segmental colorectal resection for endometriosis. STUDY DESIGN: We studied 83 women who underwent…

Endometriosis is an estrogen-dependant disease that affects 10 to 15% of women of reproductive age. Its aetiology and molecular mechanisms involved have not yet been fully explored. Endometriosis is defined by the presence of endometrium-li…

BACKGROUND: Radical en bloc hysterectomy and colorectal resection (REHCR) is the ultimate and radical surgery for extensive pelvic endometriosis. Our aims were to evaluate feasibility, quality of life, and urinary function after REHCR by la…

STUDY OBJECTIVE: To estimate the association between urinary symptoms and quality of life in patients with posterior deep-infiltrating endometriosis (DIE) with anatomical locations of endometriosis. DESIGN: Prospective nonrandomized study …

OBJECTIVE: We report the first randomized trial of laparoscopically assisted versus open colorectal resection for endometriosis focusing on perioperative complications, improvement in symptoms, quality of life, and fertility. SUMMARY OF BA…

This retrospective study of women undergoing IVF (29 with colorectal endometriosis, 157 with tubal factor infertility, and 340 with male factor infertility) found similar fertility outcomes between the groups.

BACKGROUND: Thin-section oblique axial magnetic resonance imaging (MRI) is useful in staging endometrial and cervical carcinomas but there are no data on its contribution to assessing deep endometriosis. We evaluated the contribution of thi…

Endometriosis is a common gynaecological condition affecting 10 to 15% of the female population. Deep infiltrating endometriosis (DIE) is diagnosed in 20% of women with endometriosis. Moreover, bowel endometriosis is found in five to 12% of…

STUDY OBJECTIVE: To examine transvaginal hydrolaparoscopy (THL) practices in French tertiary care centers. DESIGN: Prospective longitudinal study (Canadian Task Force classification III). SETTING: University hospital in France. PARTICIPA…
