To assess the elasticity of the pelvic floor muscle (PFM) affected by deep infiltrating endometriosis (DIE) with transperineal elastography.
This prospective observational study included 88 patients who were diagnosed with DIE, ovarian endometrioid cyst, or ovarian teratoma. All the patients were assigned to one of the three groups and underwent transperineal elastography. The scoring system and strain ratio (SR) values were recorded and analyzed. Assessments were conducted at maximal Valsalva and under quiescent condition, respectively.
The mean elastography score was statistically significantly higher for the levator ani of group I than groups II and III under quiescent condition. In addition, SR of the levator ani in group I was higher than that in groups II and III. However, at maximal Valsalva, the mean elastography score of group I was lower than that of groups II and III. In addition, SR of group I was lower than that of groups II and III.
The elasticity of the PFM in DIE patients could be qualitatively evaluated by transperineal elastography. The coordination of the PFM was injured and decreased elasticity appeared in DIE patients.
通过经会阴弹性成像评估深部浸润性子宫内膜异位症（DIE）对盆底肌肉（PFM）弹性的影响。
这项前瞻性观察性研究纳入了88例被诊断为DIE、卵巢子宫内膜样囊肿或卵巢畸胎瘤的患者。所有患者被分为三组之一，并接受经会阴弹性成像检查。记录并分析评分系统和应变率（SR）值。分别在最大瓦尔萨尔瓦动作时和静息状态下进行评估。
在静息状态下，I组肛提肌的平均弹性成像评分在统计学上显著高于II组和III组。此外，I组肛提肌的SR高于II组和III组。然而，在最大瓦尔萨尔瓦动作时，I组的平均弹性成像评分低于II组和III组。此外，I组的SR低于II组和III组。
经会阴弹性成像可对DIE患者的PFM弹性进行定性评估。DIE患者的PFM协调性受损，弹性降低。
