Comparison of 3-Dimensional Pelvic Floor Ultrasonography and Defecography for Assessment of Posterior Pelvic Floor Disorders

Purpose: The aim of this study was to determine the accuracy of 3-dimensional (3D) pelvic floor ultrasonography and compare it with defecography in assessment of posterior pelvic disorders.Methods: Eligible patients were consecutive women undergoing 3D pelvic floor ultrasonography at one hospital between August 2017 and February 2019. All 3D pelvic floor ultrasonography was performed by one examiner. A total of 167 patients with suspected posterior pelvic disorder was retrospectively enrolled in the study. The patients were divided into 3 groups according to the main symptoms.Results: There were 82 rectoceles on defecography (55 barium trapping) and 84 on 3D pelvic floor ultrasonography. Each modality identified 6 enteroceles. There were 43 patients with pelvic floor dyssynergia on defecography and 41 on ultrasonography. There were 84 patients with intussusception on defecography and 41 on 3D pelvic floor ultrasonography. Agreement of the 2 diagnostic tests was confirmed using Cohen’s kappa value. Rectocele (kappa, 0.784) and enterocele (kappa, 0.654) both indicated good agreement between defecography and 3D pelvic floor ultrasonography. In addition, pelvic floor dyssynergia (kappa, 0.406) showed moderate agreement, while internal intussusception (kappa, 0.296) had fair agreement.Conclusion: This study showed good agreement for detection of posterior pelvic disorders between defecography and 3D pelvic floor ultrasonography.

The vagina plays a focal point in support by directly supporting the bladder, urethra, uterus, and rectum. The vagina also is a central location for connective tissue and muscle attachments. Failure in any component of this intricate support system can lead to the development of pelvic floor disorders, such as pelvic organ prolapse (POP), urinary and fecal incontinence and sexual dysfunction.

Anti-nuclear antibodies (ANA) have traditionally been evaluated using indirect fluorescence assays (IFA) with HEp-2 cells. Quantitative immunoassays (EIA) have replaced the use of HEp-2 cells in some laboratories. Here, we evaluated ANA in 400 consecutive and unselected routinely referred patients using IFA and automated EIA techniques. The IFA results generated by two independent laboratories were compared with the EIA results from antibodies against double-stranded DNA (dsDNA), from ANA screening, and from tests of the seven included subantigens. The final IFA and EIA results for 386 unique patients were compared. The majority of the results were the same between the two methods (n=325, 84%); however, 8% (n=30) yielded equivocal results (equivocal-negative and equivocal-positive) and 8% (n=31) yielded divergent results (positive-negative). The results showed fairly good agreement, with Cohen’s kappa value of 0.30 (95% confidence interval (CI) = 0.14–0.46), which decreased to 0.23 (95% CI = 0.06–0.40) when the results for dsDNA were omitted. The EIA method was less reliable for assessing nuclear and speckled reactivity patterns, whereas the IFA method presented difficulties detecting dsDNA and Ro activity. The automated EIA method was performed in a similar way to the conventional IFA method using HEp-2 cells; thus, automated EIA may be used as a screening test.

Abstract Purpose: Levator ani defect (LAD) closely correlates with pelvic organ prolapse. This study aimed to compare the LAD grading between 3-dimensional ultrasonography (3D-US) and magnetic resonance imaging (MRI) and investigate the reasons for the difference using 3-dimensional pelvic models. Methods: Seventy-two Chinese women who were to undergo repair surgery were assessed by the prolapse staging, 3D-US and MRI. LAD was graded according to the grading systems described with regard to 3D-US (Dietz et al.) and MRI (Delancey et al.) The puborectalis attachment width and the puborectalis thickness were measured on the reconstructed pelvic models offline within the software. The results were analyzed using the weighted kappa and the ANOVA test. Results: The grading systems used for 3D-US and MRI showed the good agreement (k=0.75), whereas the consensus of the extent (ie, partial or complete) of tears showed the moderate agreement (k=0.56). Additionally, iliococcygeus tears detected by MRI (n=3) accompanied with complete puborectalis tears on the same side. The averaged width of intact puborectalis attachment was 13.75±3.43mm. The width of intact puborectalis attachment was remarkably higher than that of the injured attachment (P=.005). The averaged puborectalis thickness was 9.85±2.13mm. Conclusions: Comparison of 3D-US and MRI showed the good agreement on LAD grading. The moderate agreement in assessing partial or complete tears resulted from the grading criteria of 3D-US. The morphological characteristics of puborectalis assisted in identifying complete tears.

Introduction: Lateral throat form (LTF) is the critical area which has to be recorded properly for obtaining proper retention and stability in complete denture especially in geriatric patients with resorbed ridges. Popular method used for determining LTF is Neil’s method which depends on the forces applied by the floor of mouth when the tongues protrude out. Since the perception of the forces differs among different operators, there are high chances of error in the classification. So, customized instrument was fabricated to prevent this inter-observer variation. The aim of the study was to compare the inter-observer accuracy between Neil’s method of classification and classification done by customized gauze. Methods and methodology: Total 30 edentulous patients were taken. Two observers measured the LTF depth by customized tool and also by Neil’s method. Cohen’s kappa test was used to evaluate the agreement between two operators in two different classifications. Result: The agreement between the two observers was evaluated by means of Cohen’s kappa value. There was good agreement between observers in proposed classification done by customized tool with kappa value 0.658 and fair inter-observer agreement with kappa value 0.0492. Conclusion: The method of measuring the depth of LTF with fabricated instrument was more accurate and reliable than Neil’s method.
