Transvaginal echography in the study of the rectum. A new method with rectal distension with water


, : Transvaginal echography in the study of the rectum. A new method with rectal distension with water. La Radiologia Medica 85(3): 203-208

Transrectal sonography (TRUS) accurately assesses the depth of invasion in the staging of rectal carcinomas. However, the method is limited in the evaluation of upper rectal and highly stenotic rectal cancers. These conditions can be demonstrated in female patients by transvaginal sonography (TVUS) with a 5-MHz convex probe. Conventional TVUS becomes even more accurate when the rectum is distended with water. Twenty-one asymptomatic female patients were examined in a prospective study to assess the value of conventional versus water-distended TVUS. Water improves rectal depiction because it eliminates air and fecal artifacts. In our series, the rectum was demonstrated from anum to rectosigmoid junction in all cases. The whole rectal outline could also be demonstrated. Besides rectal lumen evaluation, the method allowed rectal wall layers and perirectal fat to be detailed. Subsequently, 14 female patients were examined--8 during the preoperative staging and 6 during the follow-up. In preoperative patients, the extent of stenosing rectal cancer and perirectal fat infiltration were assessed; in postoperative patients rectal recurrences were excluded. In conclusion, TVUS with rectal distension by means of water is a new diagnostic procedure which can markedly improve the US imaging of highly stenosing rectal cancers.
