Objective To examine the reproducibility of assessment of severity of pelvic endometriosis by transvaginal ultrasound scan (TVS). Methods This was a prospective observational study from August 2006 to July 2009 conducted in two Academic Departments of Obstetrics and Gynaecology. All patients underwent a TVS performed by two ultrasound observers and a laparoscopic assessment of pelvic endometriosis. Each of the ultrasound observers was blinded to the results of the other observer. The reproducibility of TVS was examined by calculating the interobserver agreement between the observers for the American Society of Reproductive Medicine score and stage and the diagnosis of deeply infiltrating endometriosis (DIE). Results Thirty four patients were recruited to the study and had a TVS performed by both ultrasound operators. Of these patients, one did not have a laparoscopy and was therefore excluded from the final analysis. 12 (36.4%) patients had no endometriosis found, 1(3%) had minimal disease, 1 (3%) had mild disease, 5 (15.2%) had moderate disease and 14 (42.4%) had severe disease. The inter rater agreement was very good between examiner A and B (kappa = 0.931). The agreement between the TVS and laparoscopy findings was also very good (kappa = 0.955 and 0.966 for examiners A and B respectivley). The limits of agreement between observers A and B were -16.6 and 12.7. The mean difference was -1.9. Conclusion TVS is a reproducible method for the assessment of the severity of pelvic endometriosis. Copyright © 2012 ISUOG. Published by John Wiley & Sons, Ltd.
