Disclaimer

Status Of Recommendations Each pathway is designed to assist clinicians in situations when faced with a large array of possible diagnostic tests and examinations. However, it is recognised that diagnostic practice may differ from a particular pathway depending on local availability of equipment and expertise, as well as the experience of individual clinicians. Therefore each pathway is neither a rigid set of rules, nor a substitute for clinical assessment, and individual patient circumstances should always be considered.

Abnormal Vaginal Bleeding in Premenopausal Women

Abnormal vaginal bleeding in premenopausal women

  • Dysfunctional bleeding
  • Benign uterine pathology e.g. submucous fibroids, polyps, endometrial hyperplasia, adenomyosis
  • Endometrial cancer
  • Cervical pathology
  • Systemic disorders e.g. hypothyroidism, liver and renal disease, coagulopathy

  • Causes of abnormal pre-menopausal bleeding include
    • Dysfunctional bleeding
    • Benign uterine pathology; e.g. submucous fibroids, polyps, endometrial hyperplasia, adenomyosis
    • Endometrial cancer
    • Cervical pathology; e.g. infection
    • Systemic disorders; e.g. hypothyroidism, liver and renal disease, coagulopathy

Factors That Increase The Risk of Endometrial Carcinoma / Hyperplasia

Factors that increase the risk of endometrial carcinoma / hyperplasia

  • Age >35
  • Obesity
  • Infertility
  • Chronic anovulation
  • Family history of colon or endometrial carcinoma
  • Patient on tamoxifen
  • Diabetes / insulin resistance
  • Polycystic ovarian syndrome

  • Age >35

  • Polycystic ovarian syndrome

Transvaginal Ultrasound (TVUS) +/- Saline Infusion Sonohysterography (SIS)

Transvaginal ultrasound (TVUS) +/- saline infusion sonohysterography (SIS)

Useful for determining endometrial thickness and any focal abnormalities and should be performed during the follicular phase.

  • Although significant endometrial pathology is not particularly common in premenopausal women, up to 20% of cases of endometrial carcinoma do occur in this group. The majority of these occur in women aged between 40 and 50 ,
  • Endometrial hyperplasia is a recognised precursor for endometrial carcinoma, with the likelihood of progression depending on the degree of hyperplasia
  • Features of TVUS
    • Useful for excluding endometrial carcinoma and structural lesions such as fibroids and polyps
    • Should be performed during the follicular phase and preferably on day 4,5 or 6 of the bleeding cycle when the endometrium is at its thinnest
    • If the endometrial thickness is less than 12mm the likelihood of endometrial hyperplasia is low
    • The sensitivity of TVUS for the detection of endometrial hyperplasia or carcinoma has varied from 33-100% and the specificity from 79-99%
  • Features of SIS
    • Improves the diagnostic accuracy of TVUS
    • Involves the installation of 5-10mls of sterile saline into the endometrial cavity and visualisation with transvaginal ultrasonography
    • More accurate than TVUS alone for diagnosing intracavitary lesions and is more accurate than hysteroscopy in diagnosing endometrial hyperplasia ,,
    • Approximately equivalent accuracy to hysteroscopy in the diagnosis of endometrial carcinoma
