Abstract

OBJECTIVE:

To review the imaging appearances, management and outcome of a large number of children with intussusception owing to pathologic lead points (PLP) in an attempt to define the role of various imaging modalities in this clinical setting.

MATERIALS AND METHODS:

Review of the records and imaging studies of 43 children with intussusception due to PLP diagnosed between 1986 and 1999.

RESULTS:

The commonest PLP found were Meckel diverticulum, polyps, Henoch-Schonlein purpura and cystic fibrosis. PLP were depicted on sonography in 23 (66%) of 35 patients, on computed tomography in 5 (71%) of 7, on air enema in 3 (11%) of 28, and on barium enema in 6 (40%) of 15. Air enema successfully reduced 60% of the intussusceptions. Nine children had recurrent intussusceptions.

CONCLUSION:

Sonography depicted two-thirds of PLP and provided a specific diagnosis in nearly one-third of our series. Our review does not provide sufficient data on how to continue the investigation of those patients in whom sonography does not depict a PLP but in whom there is a high index of suspicion for its presence. It remains a diagnostic challenge as to how to search for PLP in these patients, and other imaging modalities have to be requested according to each particular case.
