Abstract |
A clinical assessment of the 30 patients with extrahepatic biliary atresia who were admitted to the
Department of Pediatrics and pediatric Surgery, Yonsei University College of Medicine from January,
1979 to January, 1987 was performed. In 21 patients who underwent hepatic portoenterostomy, the
relationship between outcome and surgery was analyzed. Finally, collelations between lonterm
prognosis and the histopathology of biopsied liver tissue, postoperative bile restoration, and complica-
tions were evaluated in 12 patients who were followed from one and half to 24 months.
The results were as follows:
1) Among 30 patients (14 male and 16 female) of congenital extrahepatic biliary atresia, 16 (53%)
were younger than 2 months of age and 6 (20%) were older than 3 months of age on admission.
2) Jaundice and an acholic stool were present in all 30 cases. Hepatomegaly was noted in 70% and
splenomegaly in 53%. Ileal atresia, umbilical hernia and bronchogenic cyst were associated in each
of 3 cases, respectively.
3) Twenty five cases (83%) had a total serum bilirubin level between 6 and 18 mg/dl, while only one
case had that of less than 6 mg/dl. The direct bilirubin level was higher than 4 mg/dl in 25 cass (83
%). SGPT levels were less than 200IU/L in 26 cases (87%), and none exceeded 400IU/L. The
alpha-fetoprotein level was increased in all studied cases with the mean level of 3.34 ±1.07 yg/dl.
4) HBsAg was noted in 2 of 25 cases, rubella virus infections in 2 of 21 cases, cytomegalovirus
infections in 3 of 21 cases, and congenital syphilis in 2 of 24 cases.
5) Postoperative bile restoration was achieved in 15 (71%) of the 21 cases which underwent a
hepatic portoenterostomy. There were no specific correlations between postoperative bile restoration
and the age at operation, the types of extrahepatic biliary atresia, or the histologic changes of liver.
6) The degree of hepatic fibrosis was correlated with age. Seventy five percent of the patients
younger than 2 months of age showed moderate to severe degree of hepatic fibrosis.
7) The incidences of postoperative ascending cholangitis and portal hypertension were.75% and 50
%, respectively.
8) Of the 12 cases followed up, 4 cases (33%) showed clinical improvement. Their mean age at the
time of operation was 62 days, and 3 cases showed a mild degree of hepatic fibrosis and one a
moderate degree. Ascending cholangitis developed in 2 cases, but portal hypertension did not
develope. Of the 8 patients who died during the follow up period, 5 showed a moderate degree of
heaptic fibrosis and 3 a severe degree. Ascending cholangitis had developed in 7 cases, and portal
hypertension in all 8 cases. These results suggest that the younger the age at operation, the less
hepatic fibrosis, and the absence of postoperative complications are correlated with a good prognosis. |
