Intussusception in Childhood: The Role of Plain Abdominal Radiographs
Abstract
- PURPOSE
The purposes of this study were to evaluate the plain radiologic findings of the childhood
intussusception and to evaluate the role of plain abdominal films in predicting the success of air or barium reduction.
SUBJECTS AND METHODS
We retrospectively reviewed 140 cases with the diagnosis of intussusception in
children. The radiological signs that included soft tissue mass, dilatation of small bowel suggesting obstruction,
crescent sign, and target sign were evaluated in terms of frequency. The relationship between radiological
findings and outcome of reduction was analyzed. The site of soft tissue mass or crescent sign seen on plain
radiographs was correlated with the position of the apex of the intussusceptum seen at the beginning of barium
enema. The degree of dilated small bowel was evaluated by calculating the proportion of air-filled small bowel
occupying peritoneal cavity and measuring the maximal diameter of dilated bowel lumen. The radiological
finding for small bowel obstruction is determined by observation of the degree of small bowel dilatation and/or
air-fulid levels.
RESULTS
Ninety-two cases out of 140 showed one or more radiographic signs. Two most common signs were
soft tissue mass and small bowel obstruction. The success rate of air or barium reduction was significantly
lower in patients with most severe degree of dilatation of small bowel and/or more than 7 air-fulid levels on
erect view. The suspected location of intussusception on plain radiographs correlated well with the true location
of intussusception seen in the first few seconds of barium reduction.
CONCLUSION
Plain abdominal radiography is useful in the diagnosis of intussusception and provides helpful
informations for the reduction procedure as well as for the exclusion of the contraindications such as bowel
perforation.
