Abstract:
PURPOSE: The purpose of this study was to investigate the predictive factors of saline reduction under ultrasound-guidance in patients with intussusception. METHODS: Ultrasound-guided saline enema reductions were performed in 105 patients with intussusception from September 1993 to April 1996 at Ewha Womans University Mok-dong Hospital. Clinical characteristics and ultrasonographic findings were analyzed as the predictive factors of ultrasound-guided saline enema reduction in 15 patients(14.3%) who were not reduced by saline enema reduction compared to 90 patients(85.7%) who were reduced. RESULTS: The mean age of the not-reduced group was 8.9+/-5.8 months old which was significantly younger than 14.5+/-15.4 months old of the reduced group(P<0.05) There were no significant differences in sex and clinical symptoms between the two groups(P>0.05). Among the ultrasonographic findings, the thickness of the hypoechoic outer rim in the not-reduced group was 10.5+/-3.3mm which was significantly thicker than 7.4+/-1.8mm of the reduced group(P<0.05). In stepwise logistic regression analysis, hypoechoic outer rim thickness over 8mm contributed significantly as the predictive factor for the failure of ultrasound-guided saline enema reduction(P<0.05). CONCLUSION: The thickness of the hypoechoic outer rim over 8mm on ultrasonogram was the predictive factor for the failure of saline reduction.
