简要总结
Endometriosis, a condition in which the lining of the uterus grows on nearby tissues, is a common condition that affects women of reproductive age worldwide. The diagnosis of endometriosis is usually made at surgery. The most common symptom is pelvic pain. This pain may occur at the same time as menstrual bleeding, at other times of the cycle, or during or after sexual intercourse. Previous studies reveal the diagnosis of endometriosis is often delayed between 8 and 12 years after the first symptoms. Women with chronic pelvic pain report a lower quality of life. No studies, however, have been conducted to assess whether women with endometriosis-related pelvic pain are affected differently than those with pelvic pain from other or no identifiable causes.
This large-scale study is designed to gather prospective epidemiological data on the impact of and risk factors for endometriosis across countries worldwide. A study of this scale and scope has never been performed; it is anticipated that the study will provide novel insights into the effects of the condition and associated symptoms on women s lives across different countries, as well as explore differences in the effects of various potential risk factors.
This is an international study conducted at more than 20 sites worldwide and coordinated by Oxford University in the United Kingdom. At the National Institutes of Health, 250 premenopausal women between 18 and 45 years of age who are having their first diagnostic laparoscopy or laparoscopy for tubal sterilization will participate. None will have had a prior diagnosis of endometriosis through surgery. Women will be informed about the study when their laparoscopy is scheduled.
Procedures
- Patient completion of an online questionnaire before scheduled surgery. The following will be assessed by the questionnaire:
- Quality of life
- General gynecologic and medical history
- Family history
- General information
- Use of health care services
- Risk factors
- Surgeon completion of questionnaire about surgical findings.
- Follow-up: Women who consent will be contacted every 1 2 years.
详细描述
This large-scale study is designed to gather prospective epidemiological data on the impact of and risk-factors for endometriosis across countries world-wide. A study of this scale and scope has never been performed; it is anticipated to provide novel insights into the effects of the condition and associated symptoms on women s lives across different countries, as well as explore (differences in) the effects of various potential risk-factors.
Study Design: This is a clinic-based patient survey of prospectively recruited women undergoing a laparoscopy for symptoms suggestive of endometriosis or for tubal sterilization. Descriptive, as well as nested case-control studies will be conducted using information collected from patients in the registry to investigate the impact of endometriosis and associated symptoms, and test etiological hypotheses.
Primary Outcome: The primary purpose of this survey is to collect systematic, comprehensive epidemiological information on the impact of endometriosis among women world-wide, in terms of prevalence, diagnostic delay, quality of life, economic effect indicators, health care utilization, and risk-factors.
Secondary Outcomes: A secondary purpose of the register is to provide a frame-work for future follow-up studies of women diagnosed with endometriosis, allowing the investigation of indicators of effectiveness of different treatment options; long-term quality of life issues, as well as personal and economic (productivity) costs of endometriosis. The multi-center nature of the study should allow variability of endometriosis illness outcomes and associations to be assessed across participating countries.
