This is a common disorder characterized by the presence of endometrial glands and stroma outside of the endometrial cavity (1).
- it is a benign condition but one which is of great importance in gynaecology because the distressing symptomatology, the association with infertility and the potential for invasion of the gastrointestinal and urinary tracts.
- these ectopic tissues induce an estrogen-dependent chronic inflammatory process (1) and are usually seen in the pelvis, but lesions in the extraplevic sites have also been reported (e.g. lungs, brain skin, external genitalia) (2)
Classically it is described in women in their thirties and forties, particularly, Caucasians. However, as the use of laparoscopy has become widespread, this description has become less accurate.
NICE note that (3):
- delayed diagnosis is a significant problem for women with endometriosis
- delays of 4 to 10 years can occur between first reporting symptoms and
confirming the diagnosis...
- delays of 4 to 10 years can occur between first reporting symptoms and confirming the diagnosis...
- diagnosis can only be made definitively by laparoscopic visualisation of
the pelvis, but other, less invasive methods may be useful in assisting diagnosis,
- management options for endometriosis include pharmacological, non-pharmacological
and surgical treatments
- endometriosis is an oestrogen-dependent condition - most drug treatments for endometriosis work by suppressing ovarian function, and are contraceptive
- surgical treatment aims to remove or destroy endometriotic lesions
- choice of treatment depends on the woman's preferences and priorities in terms of pain management and/or fertility
