A disposable absorbent article, such as a disposable diaper. The disposable absorbent article has a topsheet with apertures large enough for low-viscosity fecal material to pass through to a fecal material storage element. The fecal material storage element immobilizes the fecal material in position for dewatering, so that the solid components of the fecal material are separated from the liquid components of the fecal material and the liquid components can be absorbed by an absorbent core. This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed. The fecal material storage element may extend beyond one or more edges of the absorbent core.
