Bidimensional Rectal-water Contrast-transvaginal Ultrasonography (2D-RWC-TVS) Versus 3D-RWC-TVS in the Diagnosis of Rectosigmoid Endometriosis

Ospedale Policlinico San Martino240 enrolled

Overview

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.

Conditions

Endometriosis, Rectum Endometriosis of Colon

Interventions

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