비장동맥 저항지수는 알콜성 간경화와 B형 간경화를 구분하는 보조 인자가 될 수 있는가? = Can theSplenic Artery Resistive Index Be an Ancillary Sign on Ultrasound for the Differentiation of Alcoholic Cirrbosis from Hepatitis B-virus Related Cirrhosis?

다국어 초록 (Multilingual Abstract)

=PURPOSE : We wanted to assess the usefulness of the splenic artery resistive index (RIS) for differ-entiating between alcoholic cirrhosis (AC) and hepatitis B-virus related cirrhosis (VC).
MATERIALS and METHODS :A total of 109 subjects (28 normal healthy controls, 38 patients with VCand 43 patients with AC) were included in this study. The spleen sizes, Child-Pugh scores andRISs were compared between the two cirrhotic groups. The receiver operating characteristic(ROC) curve was used to determine an RIS cutoff value for the differentiation of the two cir-rhotic groups.
RESULTS :The mean spleen size and mean RIS in the controls were less than those of the two cir-rhotic groups (p < 0.05), and the mean spleen sizes and Child-Pugh scores were not differentbetween the two groups (AC vs. VC), (13.1 ±3.2 cm vs. 12.9 ±2.6 cm, p > 0.05; 6.6 ±1.9vs. 5.9 ±1.6, p > 0.05, respectively). In contrast, the mean RIS of the AC patients was signifi-cantly higher than that of the VC patients (0.72 ± 0.07 vs. 0.62 ± 0.06, respectively, p <0.01). The sensitivity, specificity and accuracy at an RIS cut-off value of 0.7 for differentiatingthe two cirrhotic groups were 76.7%, 68.4% and 72.8, respectively.
CONCLUSION : The RIS is useful factor for differentiating the patients with AC from the patientswith VC.
