Recurrent intussusception. Analysis of a series treated with hydrostatic reduction.

The appearances at conventional radiography and barium enema were compared in a series of 35 patients with recurrent intussusception and in the same number of cases with an uncomplicated course. Only minor disparities between the groups could be established. The significance of a sparse amount of intestinal gas pointing to intussusception and the implication of a complete evacuation of the bowel following barium enema are stressed. The latter phenomenon, occasionally combined with persistent mild small bowel meteorism, occurred in approximately one-third of all early relapses. Patients with one manifest relapse run a significantly increased risk of further recurrences although in the majority of cases no significant etiologic factors are encountered.
