Reliability of ultrasonography in the diagnosis of acute intestinal intussusception in children

Ultra-sound imaging finding of the invaginated bud are described in 111 young children referred with a suspected acute intestinal intussusception [A.I.I.] during a period of 32 months. An initial group of 30 children were examined by ultrasonography and a barium enema for diagnostic and possible therapeutic purposes. The second series of 81 children had a therapeutic enema only when ultra-sound images provided a positive diagnosis. The authors consider that the overall accuracy for ultrasonography in A.I.I. was 100%, and suggest an algorithm for pratical decisions in A.I.I. in children
