Brief summary

Three-dimensional (3D) rendering may be employed during transvaginal rectal water-contrast transvaginal ultrasonography (RWC-TVS) for detecting the presence and describe the characteristics of rectosigmoid endometriosis. This study aims to evaluate the impact of bowel preparation on the diagnostic parameters of 3D-RWC-TVS in women with suspicion of rectosigmoid endometriosis.

Detailed description

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. In the last years, three-dimensional (3D) rendering has been employed during transvaginal ultrasound for benign gynecological diseases.

Interventions

PROCEDURE3D-RWC-TVS with bowel preparation

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. Bowel preparation is based on a low-residue diet given in the two days before the examination and a rectal enema administered a few hours before the procedure.

PROCEDURE3D-RWC-TVS without bowel preparation

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.
