Study Details

Study Description

Brief Summary

An accurate diagnosis of the presence, location and extent of the rectosigmoid endometriosis is of paramount importance for the clinicians in order to inform the patients on the potential surgical or medical treatments. It is well established that transvaginal ultrasonography is the first-line investigation in patients with suspicion of deep infiltrating endometriosis.

An improvement in the performance of transvaginal ultrasonography in diagnosing rectosigmoid endometriosis may be obtained by using rectal water contrast during transvaginal ultrasonographic scan.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: Three-dimensional rectal water contrast transvaginal ultrasonography (3D-RWC-TVS)
  • Diagnostic Test: Two-dimensional rectal water contrast transvaginal ultrasonography (2D-RWC-TVS)

Arms and Interventions

Arm Intervention/Treatment
Patients with suspicious of rectosigmoid endometriosis

Diagnostic Test: Three-dimensional rectal water contrast transvaginal ultrasonography (3D-RWC-TVS)
Rectal water contrast transvaginal ultrasonography is based on the distention of rectosigmoid with saline solution. Three-dimensional reconstructions convert standard 2D grayscale ultrasound acquisitions into a volumetric dataset.

Diagnostic Test: Two-dimensional rectal water contrast transvaginal ultrasonography (2D-RWC-TVS)
Rectal water contrast transvaginal ultrasonography is based on the distention of rectosigmoid with saline solution.

Outcome Measures

Primary Outcome Measures

  1. To compare the accuracy of 3D-RWC-TVS and 2D-RWC-TVS in the diagnosis of rectosigmoid endometriosis. [At maximum 6 months before laparoscopic surgical approach]

    The results of imaging will be compared with surgical and histological findings.

Secondary Outcome Measures

  1. To compare the precision of 3D-RWC-TVS and 2D-RWC-TVS in estimating the length (mid-sagittal diameter) of the rectosigmoid endometriotic nodules [At maximum 6 months before laparoscopic surgical approach]

    The results of imaging will be compared with surgical and histological findings.

  2. To compare the accuracy of 3D-RWC-TVS and 2D-RWC-TVS in the diagnosis of multifocal rectosigmoid endometriosis. [At maximum 6 months before laparoscopic surgical approach]

    The results of imaging will be compared with surgical and histological findings.

  3. To compare the precision of 3D-RWC-TVS and 2D-RWC-TVS in estimating and the distance between the lower margin of the rectosigmoid endometriotic nodules and the anal verge [At maximum 6 months before laparoscopic surgical approach]

    The results of imaging will be compared with surgical and histological findings.

  4. To compare the precision of 3D-RWC-TVS and 2D-RWC-TVS in estimating rectosigmoid lumen stenosis due to endometriotic nodule [At maximum 6 months before laparoscopic surgical approach]

    The results of imaging will be compared with surgical and histological findings.
