The #ENZIAN classification (2021) is the most comprehensive staging system for deep infiltrating endometriosis (DIE). It classifies DIE into four compartments. Which compartment does the 'F' subdivision in the #ENZIAN classification represent?

• A Other locations (non-DIE endometriosis: peritoneal, superficial, ovarian) ✓
• B Posterior compartment (rectovaginal septum, vagina, rectum)
• C Anterior compartment (bladder, vesico-uterine space)
• D Lateral compartment (parametria, ureters)

Explanation

In the #ENZIAN classification (2021 update), the compartments are: A = posterior (rectovaginal septum, vagina, rectum), B = lateral (parametria, sacrouterine ligaments, ureters, pelvic sidewall), C = anterior (bladder), and F = other/additional endometriosis not classified as DIE (including superficial peritoneal endometriosis, ovarian endometrioma, adenomyosis). The 'F' compartment captures all non-DIE endometriosis with sub-categories FA (superficial peritoneal), FB (endometrioma), FC (adenomyosis). This classification is used alongside the rASRM staging (which grades pelvic adhesion extent) to provide comprehensive mapping for surgical planning and research.
