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.

Conditions

• Endometriosis, Sigmoid
• Endometriosis, Rectum

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Three-dimensional (3D) rectal water contrast transvaginal ultrasonography	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	Computed colonography	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.
