| Abstract;Newly developed anorectal ultrasonographic probe (the rectal probe) for the anorectal lesions was examined and evaluated it's efficacy. Specification of this rectal probe, produced by OLYMPUS Optical co., is mechanical-radial type ultrasonographic probe which is 15cm in length and 12mm in diameter stick type probe with a frequancy of 7.5 or 12MHz and is provided a 360-degree scanning angle. This probe is able to connect to the EUM30 and is equipped water pouring system and suction mechanism. Subjects were 40 cases of anorectal lesions, composed of 14 cases with rectal tumor (4 adenomas, 3 early cancers, 7 advanced cancers), 1 with metastatic rectal tumor, 3 with submucosal tumor, 2 with operated colonic cancer, 5 with ovarian tumor, 14 with rectal varices and hemorrhoids, 1 with rectal mucasal proraps syndrome. After endoscopic observation, the lesions were examined by the ultrasonographic probe with water-filling method. The rectal probe was examined by water-filling method or balloon method. All cases could be examined easely and safely. Appropriate image for accurate diagnoses were obtained in 35 cases among of 40 (87.5%). 2 cases could not obtain good images by using the rectal probe, because these lesions were too small to find out without endoscopic systems. (Each diameter was less than 3mm.) However, most of the lesions were clealy demonstrated by using the rectal probe. Therefore, this rectal probe is useful in diagnose the anorectal lesions of which diagnosis were insufficient with the use of ultrasonographic probe alone. (author abst.) |
