When pain is not the whole story: Presenting symptoms of women with endometriosis.

BACKGROUND: Endometriosis affects one in nine Australian women of reproductive age, and is often associated with pain and infertility. However, many women may be asymptomatic, or present with alternative symptoms. AIM: To identify reasons for initial specialist referral among patients with endometriosis. MATERIAL AND METHODS: Patients were identified as having endometriosis intraoperatively based on International Classification of Diseases coding. Operation reports were reviewed and graded for severity of disease. This cohort was then retrospectively audited to identify reasons for initial referral to the general gynaecology, endosurgery, gynae-oncology, reproductive medicine outpatient departments (OPD) at the Mercy Hospital for Women in Melbourne between 1 February 2015 and 31 December 2016. RESULTS: Three hundred patients were identified as having endometriosis at laparoscopy, including 90 women with Stage IV disease. Patients were a mean (SD) age of 33.1 (7.6) years. While pain remained a common reason for referral (61.7% of referrals), 36.7% of women with Grade IV disease did not have pain included in their referral letter. Severe disease was associated with increased age (regression coefficient 0.05; 95% CI: 0.03-0.07, P < 0.01), but not with pain symptoms. Women referred with ovarian cysts or masses were more likely to be diagnosed with severe disease (regression coefficient 0.69; 95% CI: 0.37-1.01, P < 0.01). CONCLUSION: Although pelvic pain is not a good predictor for a diagnosis of endometriosis, it remains a common symptom among women with the disease. However, more than one in three patients with Grade IV endometriosis presented without mention of pain symptoms, encouraging clinicians to adopt a broader approach to the presenting symptoms of endometriosis.

Pelvic pain: What are the symptoms and predictors for surgery, endometriosis and endometriosis severity.

BACKGROUND: Chronic pelvic pain (CPP) is a common condition which significantly impacts the quality of life and wellbeing of many women. Laparoscopy with histopathology is recommended for investigation of pelvic pain and identification of endometriosis with concurrent removal. Never-the-less, the association between endometriosis and pelvic pain is challenging, with endometriosis identified in only 30-50% of women with pain. AIMS: To explore the predictors for undergoing surgery, for identifying endometriosis and endometriosis severity in a cohort of women with CPP. MATERIALS AND METHODS: This study forms part of the Persistent Pelvic Pain project, a prospective observational cohort study (ANZCTR:ACTRN12616000150448). Women referred to a public gynaecology clinic with pain were randomised to one of two gynaecology units for routine care and followed for 36 months with 6-monthly surveys assessing demographics, medical history, quality of life, and pain symptoms measured on a Likert scale. Operative notes were reviewed and endometriosis staged. RESULTS: Of 471 women recruited, 102 women underwent laparoscopy or laparotomy, of whom 52 had endometriosis (n = 37 stage I-II; n = 15 Stage III-IV). Gynaecology unit, pelvic pain intensity and lower parity were all predictors of surgery (odds ratio (OR) 0.342; 95% CI 0.209-0.561; OR 1.303; 95% CI: 1.079-1.573; OR 0.767; 95% CI: 0.620-0.949, respectively). There were no predictors identified for endometriosis diagnosis and the only predictor of severity was increasing age (OR 1.155; 95% CI: 1.047-1.310). CONCLUSIONS: Gynaecology unit and pain intensity were key predictors of undergoing laparoscopy; however, pain severity did not predict endometriosis diagnosis or staging. These findings indicate the need to review current frameworks guiding practice toward surgery for pelvic pain.
