Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Patients with suspicious of rectosigmoid endometriosis

Three-dimensional rectal water contrast transvaginal ultrasonography (3D-RWC-TVS)

Intervention Type DIAGNOSTIC_TEST

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.

Two-dimensional rectal water contrast transvaginal ultrasonography (2D-RWC-TVS)

Intervention Type DIAGNOSTIC_TEST

Rectal water contrast transvaginal ultrasonography is based on the distention of rectosigmoid with saline solution.
