Agreement between trainees and experts and trainees and laparoscopy/histology in the overall assessment of endometriosis in all 3 blocks, expressed in Kappa value. DE: deep endometriosis; p: p value; POD: pouch of Douglas; R: rectum; RS: rectosigmoid; USL: uterosacral ligament. ∗None of the 10 vaginal lesions were detected correctly by the trainees; only 4 rectovaginal septum lesions in the cohort out of which none was identified by the ultrasound trainee and only one correctly identified by the radiology trainee; adenomyosis detection was not assessed against laparoscopy/histology since only 1 patient had a hysterectomy.
