“…6 TVS was found to be an excellent adjunct to endorectal sonography in the staging of rectal cancer in women and may be particularly helpful when endorectal sonography is unsuccessful due to tumors that are stenotic or in a high or low position. 7,8 The use of TVS has been documented for other gastroenterological conditions. Inflammatory bowel disease (IBD) usually presents as a lower gastrointestinal inflammatory process with a distended gastrointestinal wall; thickened, irregular mucosa; and deep ulcerations.…”

Sonography plays a primary role in the diagnosis of gynecological diseases. A retrospective review of incidental findings report by transvaginal sonography (TVS) was performed to evaluate the ability of TVS to visualize rectosigmoid carcinoma. The authors performed a retrospective review of 450 women who were referred for TVS because of suspected gynecological indications to evaluate those with incidental findings. Of these, 15 with incidental findings were subsequently diagnosed with rectosigmoid carcinoma. The sonographic properties and clinical findings were systematically evaluated. TVS findings included solid nonhomogeneous lesions (mean diameter of 4 cm; range, 1.6-8 cm), distended rectal walls, and gas inside the gastrointestinal lumen in 53% (n = 8) of the cases. Total wall invasion was suspected, and signs of edema were noticed in 60% (n = 9) of the cases. All lesions seen by TVS were pathologically confirmed as carcinoma of gastrointestinal origin. Inspection of the rectosigmoid during a TVS examination has the ability to detect unsuspected rectosigmoid lesions.

“…The layers of the rectal wall seen by transvaginal ultrasound have the same arrangement with alternating hyper and hypoechoic layers, which permits the determination of tumor invasion similar to the endorectal approach [30,31].…”

“…Transvaginal ultrasonography shows very high specificity and sensitivity, especially in cases of advanced tumors (T3 and T4) and may help in selecting patients suitable for neoadjuvant chemoradiotherapy [30,31]. It may be the only ultrasonographic method that may visualize lesions high in the rectum close to the rectosigmoid junction or the stenotic tumors (Figure 7).…”

By endorectal ultrasonography the rectal tumors can be evaluated for their size, stage, echostructure and vascularization. Cancers in the parts of the colon beyond the rectum usually are not staged with ultrasound methods, because the primary treatment-surgical resection gives the means for definite pathohistological staging and grading. The forward-viewing radial-array echoendoscopes gives the ability to reach and evaluate these lesions. The accuracy of the collected data and its significance for clinical practice in the cases of colon tumors has to be verified by larger systematic studies [4]. The endosonographic image of rectal carcinoma is one of a hypoechoic, heterogenic lesion and the degree to which it disrupts the rectal wall layers determines the local tumor T-stage.

“…Rectal endoluminal ultrasonography (US) with rigid probes or endoscopic ultrasonography (EUS) is the preferential method for local staging of rectal carcinoma (RC) and decisively influences the therapeutic approach of patients (2). Nevertheless, its accuracy varies significantly, ranging from 63% to 95% for T staging and from 64% to 80% for N staging (1,(3)(4)(5).…”
