[New endosonographic examination technic for improving the assessment of small rectal tumors].
Conventional endosonographic techniques of examination in early carcinoma and sessile rectal adenoma have shown unsatisfactory results. We therefore fill the rectal cavity directly with water. Using this technique the anatomy of the rectal polyp is preserved, and the separate layers are easier to differentiate, especially when the 10-MHz scanner is used. The clinical results in 56 patients show an improvement concerning the preoperative staging especially in those tumors which are not palpable.
