P10.07: Hormonal treatment effect on dysmenorrhea in women with and without endometriosis

uterosacral and cardinal ligaments, pelvic sidewall (B), recto-sigmoid (C). IEC adds the evaluation of adhesions (D), ovaries (E), bladder (FB), adenomyosis (FA). All compartments were graded in three levels. A numerical score graded the total amount of disease. Rate agreement and reproducibility between the operators were calculated. Results: Multiple rate agreements to classify endometriosis through IEC ranged from substantial to almost perfect (Cohen k 0.658 – 1). A lower agreement rate, albeit substantial (Cohen k > 0.65), was detected for A, B, FA and D. The lower agreement in the evaluation of adhesions (D) was due to absence of adhesions in some patients. The lowest agreement, albeit substantial (Cohen k 0.658), was observed for the compartment level A3 (large vaginal or recto-vaginal-septal lesions). Agreement for small nodules (level 1) in compartments A, C and FB seemed to be lower than in other levels. The agreement rate for the total score levels, a reflection of the total extension of the disease, ranged from substantial to perfect. Conclusions: IEC is reproducible and easy to use during ultrasound evaluation of pelvic endometriosis. The standardisation of the diagnosis and extension of pelvic disease represents is crucial for the correct management and surgical approach. IEC is designed as diagnostic tool and as a surgical classification as well.
