Abstract

PURPOSE:

The most widely accepted classification for endometriosis is the Revised American Society for Reproductive Medicine (rASRM) system, but this does not take deeply infiltrating endometriosis (DIE) into account. The Enzian classification enables clinicians to classify DIE. Due to complexity and partial overlap with rASRM, it was revised for a second time in February 2011. Using both the systems to classify lesions would be inappropriate, as they refer to different locations. The aim of this study was to analyze whether the revised Enzian classification is easier to use and avoids duplicate classifications.

METHODS:

Retrospective study of 460 women admitted for endometriosis.

RESULTS:

One hundred and eighty-seven of 460 patients (41 %) had histologically confirmed DIE based on the revised Enzian classification. Further classification of these 187 patients using Enzian revealed 270 retroperitoneal lesions, as some patients had several DIE-type lesions simultaneously: 66 in compartment A (rectovaginal septum, vagina), 112 in compartment B (sacrouterine ligaments, pelvic wall), 58 in compartment C (bowel), 15 with adenomyosis uteri, 7 with bladder involvement, 8 with intrinsic involvement of the ureter, and 4 with bowel involvement. All 270 lesions were classified using Enzian alone and not with the rASRM score. There were no duplicate classifications (rASRM and Enzian).

CONCLUSIONS:

The revised Enzian classification is an excellent complement to the rASRM score for morphological description of DIE.
