超声诊断会阴子宫内膜异位症

目的探讨超声诊断会阴子宫内膜异位症的价值。方法回顾性分析23例经手术和病理证实的会阴子宫内膜异位症患者的声像图表现。结果 23例中,经会阴超声检出24个内膜异位症病灶。91.67%(22/24)病灶超声表现为边界不清的结节状或条束状实性低回声或囊实性混合回声,CDFI于59.09%(13/22)的病灶内探及血流信号。本组5例接受激素治疗(GnRHa),用药后病灶明显缩小。经会阴超声判断肛门括约肌是否受累均与手术结果一致。结论经会阴超声检查能够发现并诊断会阴子宫内膜异位症,并评价肛门括约肌受累情况,对术前制定手术方案具有指导意义。

Ultrasonic diagnosis of perineal endometriosis

Objective To investigate the clinical value of ultrasound in diagnosis of perineal endometriosis (PEM). Methods Perineal ultrasonic results of 23 PEM patients confirmed with surgery and histopathology were retrospectively analyzed. Results All 24 lesions in 23 patients were detected with ultrasound. Twenty-two lesions (22/24, 91.67%) manifested as hypoechoic area with unclear margins, some with small anechoic area inside. The shape of lesions were nodular or bundle-like. Blood signals were detected with CDFI in 59.09% (13/22) lesions. Volume of lesions decreased after GnRHa medication. All patients with anal sphincter involvement were diagnosed correctively with perineal ultrasonography. Conclusion Ultrasound is useful in diagnosis of PEM and evaluation on anal sphincter involvement, therefore should be used as an imperative imaging modality in preoperative decision of these patients.
