Abstract

Recently, a new technique of reduction for intussusception using saline solution and ultrasonogram instead of barium enema is being used in several centers. In order to evaluate its efficacy, we have conducted the clinical observation in 40 patients with intussusception who were treated by hydrostatic saline reduction under the ultrasonographic guidance in Kyung-Hee University Hospital from June 1989 to July 1990. We have observed the ultrasonographic findings in intussusception and compared the reduction rate with that of 135 cases of control group who were treated by conventional barium enema method. The results were as follows: 1) Before reduction, the diagnostic accuracy of intussusception by ultrasonography was 100%. 2) The rate of successful reduction by saline hydrostatic reduction under ultrasound guidance was 67.5% and that of barium enema was 65.2%. 3) The reduction rate of saline hydrostatic reduction in the patients who visited before 24 hours from the onset of symptoms (81.5쑈) was higher than that of those who visited after 24 hours (38.5%). These differences of reduction rate acording to onset times was also found in barium enema group. 4) The reduction rate of saline hydrostatic reduction was higher in the group of ileocoic type (85. 2%) than that of other types (30.8%). In barium enema group, however, there was no statistically significant differences of reduction rate acording to the type of intussusception. 5) There was no complications during and after the procedure. With these results, we found that ultrasonography is a safe, accurate diagnostic method in child- hood intussusception and ultrasound guided saline hydrostatic reduction was believed to be one of the most promising methods in nonoperative treatment of childhood intussusception.
