“…3D/4D-TPU is an objective and reproducible method for evaluating pelvic floor muscle function, including contraction and relaxation. Moreover, it is a non-invasive technique, compared with traditional digital examination, well tolerated by patients and relatively easy to learn 38,39 . These features make TPU particularly useful for the assessment of women suffering from CPP and DIE 13,35 .…”

What are the novel findings of this work?Pelvic floor physiotherapy appears to be a promising new treatment to improve pelvic floor relaxation, superficial dyspareunia and chronic pelvic pain in women with deep infiltrating endometriosis (DIE). What are the clinical implications of this work?In the context of tailored multidisciplinary care, pelvic floor physiotherapy may represent an additional valid, minimally invasive, innovative and well-tolerated therapeutic option for women with DIE.

“…It would be interesting to evaluate other pelvic floor dimensions, such as levator hiatal area and levator hiatal transverse diameter, using three‐dimensional ultrasound. The advantages of 3D ultrasound include the ability to measure various dimensions on different planes from the same single acquisition, the ability to examine the integrity of the LAM, and finally it has been recently shown that operators can rapidly reach an acceptable level of accuracy 29‐31 . On the other hand, the main advantage of 2D technique is its simplicity.…”

The aim of the present study was to evaluate the correlation between the proportional change of anteroposterior diameter (APD) of levator hiatus from rest to maximum Valsalva maneuver in nulliparous women at term and labor outcome. Methods: We prospectively recruited nulliparous women at term before the onset of labor. Women underwent a two-dimensional transperineal ultrasound, measuring the APD of the levator hiatus at rest and under maximum Valsalva's maneuver. APD change from rest to maximum Valsalva was described both in terms of absolute figures and proportional change. Correlation of APD change with the mode of delivery and with labor durations was assessed. Results: Overall, 486 women were included in the analysis. No significant association between change in APD and the mode of delivery. We found a significant negative correlation between change of APD from rest to Valsalva and the duration of active second stage both in terms of absolute change (Pearson's r = −0.138, P = .009) and in terms of proportional change (Pearson's r = −0.154, P = .004). Survival outcomes based on Cox-regression model showed that APD was independently associated with the duration of active second stage of labor after adjusting for epidural analgesia, maternal age

“…A previously validated reproducible technique was used for all 4D TPU acquisitions: the linear reconstruction technique (OmniView) combined with a contrast enhancement technique (volume contrast Imaging [VCI]). 13,14 The used VCI thickness was 10 to 20 mm. To visualize adequately the LAM, the aim of the threedimensional (3D) TPU acquisition is to reconstruct the plane of minimal hiatal dimensions.…”

Aims: To evaluate the intermethod agreement between the tomographic ultrasound imaging (TUI), considered as the gold standard, and the OmniView-VCI in the diagnosis of levator ani muscle (LAM) avulsion and in the measurement of levator-urethral gap (LUG). Methods:We acquired dynamic 4D transperineal ultrasound volumes from 114 women. Each data set was analyzed on maximal pelvic floor contraction by TUI and OmniView-VCI techniques to check for LAM avulsion. Moreover, we measured LUG using both TUI and OmniView-VCI, twice by an operator and once by another to assess intraobserver and interobserver reproducibility.Reproducibility and intermethod agreement were studied by means of intraclass correlation coefficient (ICC) and Cohen's kappa coefficient. Results: In the diagnosis of ani levator avulsion, the two techniques showed a good agreement (Cohen's κ = 0.691, 95% confidence interval [CI], 0.522-0.860; P < .001); we also reported a good intraobserver and interobserver agreement (Cohen's κ = 0.738, 95% CI, 0.597-0.879; P < .001, and Cohen's κ = 0.864, 95% CI, 0.750-0.978; P < .001, respectively). LUG measurements by OmniView-VCI technique showed high intraobserver (ICC 0.895; 95% CI, 0.866-0.918) and interobserver (ICC 0.821; 95% CI, 0.774-0.858) reproducibility. High intermethod agreement was demonstrated between the two methods (ICC 0.813; 95% CI, 0.764-0.853). The area under the receiver-operating characteristic curve of LUG in predicting avulsion was 0.931 (0.868-0.994, 95% CI; P < .001) with 24 mm showing the best sensitivity (82%) and specificity (97%). Conclusions:OmniView-VCI is a reliable method for LUG measurement and for levator avulsion diagnosis. K E Y W O R D S 3D ultrasound, avulsion, levator muscle, pelvic floor, transperineal ultrasound
