Pseudotumoral cecum after hydrostatic reduction of intussusception.

The authors report two cases of intestinal intussusception successfully reduced by hydrostatic pressure. A post-reduction filling defect in the cecum disappeared spontaneously on follow-up barium enema, and is therefore consistent with cecal edema. It appears an initial period of close observation for such cases is worthwhile, delaying the decision about surgery until after a follow-up barium enema; this may confirm the disappearance of the filling defect.
