Ultrasonographic diagnosis of deep infiltrating endometriosis with involvement of pelvic tissues / 中国医学影像技术

ABSTRACT

Objective To explore the diagnostic value of ultrasonography in diagnosing deep infiltrating endometriosis (DIE) with involvement of pelvic tissues.Methods Data of 118 DIE patients confirmed with surgery and pathology who underwent transvaginal ultrasonography before surgery were retrospectively analyzed.Taking surgical and pathologic findings as the gold standards,the sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) of ultrasonography in diagnosis of DIE with involvement of uterosacral ligament,intestine,vaginal rectal septum,vagina,bladder and ureter were calculated,respectively.Results Uterosacral ligament involvement was found in 85 patients,with sensitivity of 95.29％ (81/85) and specificity of 90.91％ (30/33).Intestinal involvement was observed in 60 patients,with sensitivity of 98.33％ (59/60) and specificity of 91.38％ (53/58).Vaginal rectal septum involvement was noticed in 39 patients,with sensitivity of 79.49％ (31/39) and specificity of 92.41％ (73/79).Vaginal involvement was detected in 18 patients,with sensitivity of 55.56 ％ (10/18) and specificity of 96.00 ％ (96/100).Bladder involvementwas found in 17 patients,with sensitivity of 76.47％ (13/17) and specificity of 94.06％ (95/101).Ureter involvement was also found in 9 patients,with sensitivity of 100％ (9/9) and specificity of 99.08％ (108/109).Conclusion Transvagina ultrasonography has great value in diagnosis of DIE with involvement of pelvic tissues.
