NCT04295343

Brief Summary

Rectosigmoid involvement by endometriosis causes intestinal symptoms such as constipation, diarrhea, and dyschezia. A non-invasive diagnosis of bowel endometriosis is relevant to provide the patients information on the potential hormonal or surgical treatments. The objective of the current study was to compare the performance of three-dimensional rectal water contrast transvaginal ultrasonography (3D-RWC-TVS) and computed colonography (CTC) in predicting the presence and characteristics of rectosigmoid endometriosis.

Outcome Measures

Primary Outcomes (1)

  • To compare the accuracy of 3D-RWC-TVS and CTC in the diagnosis of rectosigmoid endometriosis.

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

    At maximum 6 months before laparoscopic surgical approach

Secondary Outcomes (3)

  • To compare the precision of 3D-RWC-TVS and CTC in estimating the length (mid-sagittal diameter) of the rectosigmoid endometriotic nodules

    At maximum 6 months before laparoscopic surgical approach

  • To compare the accuracy of 3D-RWC-TVS and CTC in the diagnosis of multifocal rectosigmoid endometriosis.

    At maximum 6 months before laparoscopic surgical approach

  • To compare the precision of 3D-RWC-TVS and CTC 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

Study Arms (1)

Patients with suspicious of rectosigmoid endometriosis

Diagnostic Test: Three-dimensional (3D) rectal water contrast transvaginal ultrasonographyDiagnostic Test: Computed colonography

Interventions

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.

Patients with suspicious of rectosigmoid endometriosis
Computed colonographyDIAGNOSTIC_TEST

Computed colonography or virtual colonoscopy uses special x-ray equipment to examine the large intestine. During the exam, a small tube is inserted a short distance into the rectum to allow for inflation with gas while computed tomographic images of the colon and the rectum are taken.
