The rectosigmoid index

M J Siegel et al. Radiology. 1981 May.

Abstract

Case material was reviewed to determine the value of the rectosigmoid index in the diagnosis of both segmental and total-colon aganglionosis in infants less than one month old. Data indicate that a rectosigmoid index higher than 0.9 may rule out a diagnosis of rectosigmoid aganglionosis but may be a misleading indicator of longer segment or total-colon aganglionosis.
