Active clinical trials for "Endometriosis"

Managing chronic pelvic pain in patients with a past history of endometriosis might be a challenge for the gynaecologist. The objective of this study is to evaluate pelvic pain after treatment with radiofrequency in patients with chronic pelvic pain and surgery for endometriosis.

This is a prospective, multicentric (three centers: 1: Shanghai First Maternity and Infant Hospital, Shanghai, China; 2: International Peace Maternity and Child Health Hospital, Shanghai, China, 3: Shanghai Tongji Hospital, Tongji University School of Medicine, Shanghai ,China), randomized clinical trial that includes patients undergoing laparoscopic surgery for primary unilateral ovarian endometriomas. Eligible patients will be subjected to transvaginal ultrasound before surgery to perform cyst classification (central type, marginal type and outcrop type). Patients are divided to two group: laparoscopic cystectomy group versus laparoscopic aspiration/electrocoagulation group. Biopsy samples in aspiration/electrocoagulation group and excision samples in cystectomy group are all subjected to histopathological examination. Follicular stimulating hormone (FSH), Anti mullerian hormone (AMH) and antral follicular count (AFC) will be measured pre-operative and post-operative. The aim of the study is to determine whether and to what extent the two surgical procedures for ovarian endometrioma, cystectomy and aspiration/electrocoagulation, affect ovarian reserve. The investigators intend to confirm the clinical utility of ultrasonic classification of ovarian endometrioma, FSH, AMH and AFC in the assessment of ovarian reserve, and to promote their use in predicting decreased ovarian reserve. The surgical excision of cystic wall, cystic fluid and peritoneal fluid will be subjected to transmission electron microscope, high resolution mass spectrometry and single-cell RNA sequencing to investigate their cellular and molecular features.

Purpose: The primary objective is to evaluate the sensitivity and specificity of 18F-fluoroestradiol (FES) PET/MRI for evaluating endometriosis. Participants: A total of 12 participants will be recruited from individuals with clinically suspected endometriosis who are scheduled for planned operative laparoscopy at the University of North Carolina at Chapel Hill (UNC). Procedures (methods): This is a prospective, one arm, single center study of 12 subjects with clinically suspected endometriosis to demonstrate FES PET/MR's clinical utility for diagnosis of endometriosis. This study will be an evaluation of the radiotracer, FES, which binds to estrogen receptors and has previously been used to study estrogen receptor expression in tumors, to detect endometriosis. Participants will undergo one FES PET/MR scan within 4 weeks prior to their scheduled surgery. Participants will also complete questionnaires regarding their condition, pain, and quality of life.

To assess the feasibility of using intravenous ICG to characterize the vascular perfusion of ovaries during gynecologic surgery

The aim of our study is to evaluate whether there is a statistical difference between thyroid gland volume in patients with pathological diagnosis of endometriosis or endometrioma and in patients who underwent surgery for other gynecological reasons, and to reveal the presence of concomitant thyroid disease in these cases.

Endometriosis is associated with different types of pain (acute, chronic, excess nociception, neuropathic) generated by different mechanisms in the nervous system. The rTMS could provide significant analgesia for refractory endometriosis pain. The aim of the study is to evaluate the feasibility of transcranial magnetic stimulation (rTMS) for analgesia on chronic refractory endometriosis pain.

This study is a multicenter, randomized-control-trial. This study select 1184 Infertile patients associated with endometriosis diagnosed by laparoscopy surgery. Patients are going to be divided into two groups according to 1:1 ratio randomly assigned to receive GnRH-a. Cumulative pregnancy rate, end of treatment to natural pregnancy time, accept the assisted reproductive treatment rate, miscarriage rate, live birth rate will be recorded.

This study aims at investigating the fertility outcome of endometriosis suppression with dienogest 2mg / day for 3 month followed by induction of ovulation for 3 month in endometriosis patients stage I and II.

Does prolonged GnRH downregulation prior to ART improve the clinical pregnancy rate in postoperative endometriosis patients? (A single centre randomised controlled trial)

Under general anaesthesia, the patient is placed in the modified dorsal lithotomy position a 10-mm umbilical trocar is inserted. A panoramic view of the pelvis was obtained together with full assessment of the ovarian mass(es). Aspiration of the cyst: Veress needle is inserted in the midline 2 cm above the symphysis pubis to aspirate the cyst under laparoscopic guidance (to guide the entry of the needle into the cyst wall & to confirm complete aspiration). Delivery of affected ovary outside the abdominal cavity: Classic ovarian cystectomy will be done using microsurgical techniques in which the cyst wall will be dissected gently and carefully from the healthy ovarian tissue followed by perfect haemostasis and re-fashioning of the remaining ovarian tissue using Vicryl (3-0) sutures. Re-introduction of the ovary to inside the abdominal cavity: The stitched ovary is pushed gently inside the abdominal cavity and the minilaparotomy is re-covered by the rubber shield (to allow re-inflation of the abdominal cavity). The ovary is reassessed under laparoscopic guidance to ensure perfect haemostasis and normal position of the ovary. Pelvic irrigation is done if needed.
