Diagnostic value of endoscopic ultrasonography in pelvic masses with bowel involvement

Abstract

Benign and malignant pelvic masses with or without intestinal invasion are common in women of childbearing age. Patients may have nonspecific symptoms and signs or experience no symptoms. Laparoscopic resection of pelvic masses is currently the mainstream treatment; therefore, accurate preoperative evaluation is not only essential for patients suspected of having intestinal invasion, but also extremely important for the selection of follow-up treatment. Procedures, including endoscopic ultrasonography (EUS), pelvic magnetic resonance imaging, abdominal computed tomography, vaginal ultrasonography, barium enema, and colonoscopy, aid in determining the presence, depth, and histology of the disease. In particular, the wide application and continuous developments in EUS techniques have improved the diagnostic accuracy for intestinal subepithelial and peripheral organ lesions. This article reviewed the clinical value of EUS in the diagnosis of benign and malignant pelvic masses with bowel involvement.
