title: [Endorectal ultrasound for evaluating perirectal processes].
abstract: Between July 1992 and December 1993 we examined 258 patients by endorectal ultrasound at the Surgical Department of the University of Würzburg. In 24 (9.3%) patients we found 27 perirectal lesions. These comprised abscesses, cysts, primary and secondary malignancies, as well as various benign tumours. All lesions but one underwent histological and/or microbiological examination. Endosonographic assessment with regard to size, location and anatomical structure was correct in 24 (89%) cases. We performed ultrasound-guided, transrectal aspiration in six patients. Endorectal ultrasound is a useful complementary imaging device in the assessment of pararectal disease. Owing to its high resolution it may be superior to other methods (e.g. CT or MRI). Another advantage is the possibility of ultrasound-guided aspiration biopsy. Precise knowledge of the topographic anatomy and its endosonographic appearance is of great importance.
