The ESHRE revised #ENZIAN classification of deep endometriosis characterises lesions in which dimension?
- A Only peritoneal lesion depth in millimetres
- B Serum CA-125 correlation with lesion extent
- C Location and size of deep infiltrating lesions in specific anatomical compartments (A: vagina/rectovaginal; B: parametrium/ureter; C: bowel; F: additional lesions) ✓
- D Endometrioma diameter in centimetres only
Correct answer: C. Location and size of deep infiltrating lesions in specific anatomical compartments (A: vagina/rectovaginal; B: parametrium/ureter; C: bowel; F: additional lesions)
Explanation
The revised #ENZIAN classification (2021) specifically describes deep infiltrating endometriosis using compartments: A (vagina and rectovaginal septum), B (uterosacral ligaments, parametria, and ureter involvement), C (bowel/rectosigmoid), and additional F compartments (bladder, ureter separately). Each compartment is graded 1–3 by lesion size/severity. This replaces the older ENZIAN staging. The rASRM classification, by contrast, covers peritoneal and ovarian disease but inadequately describes deep infiltrating lesions.
