5. 임상 소견으로는 간종대는 100%에서 있었으며, 황달 및 비장종대는 각각 96%, 무담즙변은 56%였고, 이외 자반증, 소두증, 구토, 설사가 있었으며, 골 이상과 선천성 기형의 동반은 각각 12%였다.
6 .입원 당시 혈창화학적 검사 소견은 무담즙변이 있는 환아와 무담즙변이 없는 환아에서 CBC 및 간기능 검사상 통계학적으로 의의있는 차이는 없었다.
7.치료결과 내과적 치료를 시행받은 환아는 23례로 이 중 14례에서 호전을 보였으며, 7례는 점차 악화되었고 2례는 사망하였다. 선천성 담도폐쇄증이 동반되였턴 환아에서 Kasai수술법을 시행받은 환아는 2례로 모두 사망하였다.
8.추적관찰 기간은 1개월에서 24개월 사이였으며, 완치된 환아가 28%, 점차 호전을 보인 환아가 88 %, 점점 악화되었던 환아가 4%,변화가 없었던 환아가 24 %,사망한 환아가 16%였다.
9. 예후에 영향을 주는 요인으로는 재태연령이 37주 이상이고, 출생시 체중이 2.5kg이상, 황달의 발현 시기가 생후2주 이상인 환아와 간경변성 변화가 없는 환아에서는 통계학적 의의는 없었지만 호전된 례가 많았고, 무담즙변이나 또는 선천성 담도폐쇄증이 있었던 환아는 통계학적으로 의의 (P<0.05 )있게 예후가 불량하였다.

Neonatal cholestasis is classified into neonatal hepatitis, intrahepatic biliary hypoplasia and extrahepatic biliary atresia. Infections, hereditary disease and metabolic disease, etc. have been reported as causes of neonatal cholestasis.
Infective neonatal cholestasis is mainly caused by TORCH and hepatitis B virus infection. Cytomegalovirus infection are transmitted to the fetus by intrauterine infection or during delivery and account for 1.3-7.1% of neonatal cholestasis. The
prognosis of neonatal cholestasis due to cytomegalovirus infection is known to be better than others.
A clinical assessment of 25 patients with neonatal cholestasis caused by cytomegalovirus infection who were admitted to the Department of Pediatrics, Yonsei University College of Medicine from January 1983 to July 1988 was performed.
The results were as follows :
1. The patients with neonatal cholestasis caused by cytomegalovirus infection were 19% of the total patients with neonatal cholestasis from January 1983 to July 1988 and were over 30% annually stance 1987.
2. Among 25 cases, 21 cases were neonatal hepatitis, 2 cases biliary atresia and the remaining 2 cases neonatal hepatitis with biliary atresia.
3. Seventy six percent of the patients were 2-3 months of age and 13 cases were male and 12 cases were female.
4. Thirty two percent of the patients were low birth weight infants and 18% were premature neonates.
5. Hepatomegaly was present in all 25 cases. Jaundice and splenomegaly were noted in 96%, and acholic stool was noted in 56%. Congenital anomalies were noted in 12% of the patients.
6. There were no statistical differences in laboratory findings between the patients with acholic stool and those without.
7. Among 23 cases who were treated medically, 14 oases improved, 7 cases deteriorated and 2 cases died. Two cases who received Kasai operation died during the follow up period.
8. During the fellow up ported(1-24 months), 28% of the patients recovered, 25% progressively improved, 4% progressively deteriorated, 4% were stationary, and 16% died.
9. The proposed prognostic factors such as gestational age over 37 weeks, birth weight above 2.5kg, age of onset of Jaundice over 2 weeks after birth and absence of cirrhotic change were related to a favorable outcome even though statistically insignificant. In contrast, patients with acholic stool or biliary atresia were
associated with poor prognosis with statistical significance.
