Description

Primary sclerosing cholangitis (PSC) is rare in children. We treated a 10-year-old boy with PSC presenting the segmental type of hepatic hilum, of which the first symptom was icterus. Percutaneous transhepatic drainage into the dilated bilateral intrahepatic bile ducts was performed. Open biopsies of the hepatic hilum and intra hepatic bile duct specimens showed severe fibrosis and infiltration of lymphocyte, and there were no malignant findings. The nonsurgical transhepatic balloon dilatation was employed because of the lower feasibility of the total resection of the affected area. After 4 sessions of dilatation using a 7 mm balloon catheter, he recovered well and the clinical pictures became satisfactory. He has been uneventful for more than 10 years, and there are no signs of recurrence. Nonsurgical balloon dilatation is safe and effective in selected cases.
