Abstract

PURPOSE: The aim of this study was to develop a method for determination of rectal compliance that allows direct measurement of corresponding changes in the rectal crosssectional area or perimeter and rectal pressure. METHODS: We developed an anal probe for transrectal endosonography. The probe was testedin vitro,and rectal compliance of six healthy patients was determined. RESULTS:In vitromeasurements proved the method to be well reproducible. The method allowed calculation of an endosonographic rectal compliance, which correlated well with rectal compliance measured by the standard method. CONCLUSION: Endosonographic determination of rectal compliance is possible, and the endosonographic method may give a more precise and reproducible estimation of rectal compliance.
