Abstract

PURPOSE
We investigate the risk factors of recurrence after first intussusception.
METHODS
We have studied the relationship of the clinical features and ultrasonographic findings and the risk of recurrent intussusception in 97 patients with reduced intussusception including 22 recurrent intussusception who admitted at the department of pediatrics at Ewha Womans University Mok-dong hospital from September 1993 to Feburary 1996.
RESULTS
1) The overall recurrence rate of intussusception in this study was 16.9%. 2) The interval between the first and second attack was within 24 hours in 53.8%. 3) There were no stastistically significant difference in age and sex, antecedent illness, clinical symptoms and sings, type of intussusception and radiologic findings on simple abdomen. 4) There were stastistically significant difference in the average duration of symptom above 12 hours, infolding lymph node in target sign, outer hypoechoic diameter above 8mm, swelling on ileocecal valve and terminal ileum after reduction(wall thickness> 3mm) on ultrasonographic findings and number of trial of reduction more than 3 times between the nonrecurrent and recurrent groups. 5) In stepwise logistic regression analysis, hypoechoic outer rim thickness above 8mm in target sign, swelling of ileocecal valve and terminal ileum after reduction on ultrasonographic findings and number of trial of reduction more than 3 times contributed significantly to the prediction of recurrence of intussusception.
CONCLUSIONS
Recurrent intussusception can be predicted by hypoechoic outer rim thickness above 8mm in target sign, swelling of ileocecal valve and terminal ileum after reduction on ultrasonographic findings and number of trial of reduction more than 3 times.
