DIAGNOSIS AND TREATMENT OF CONGENITAL BILIARY DILATATION IN CHILDREN ( REPORT OF 25 CASES )

In this paper,we report on 25 children with congenital dilatation of the bile duct. According to our experience and a review of the literature, cystic type biliary diliatation can mostly be detected by ultrasonography, but the diagnosis of lusilorm type is rather difficult. An investigation by endoscopic retrograde cholangiopancreaticography ( ERCP ) and/or intraop-erative cholangiography should be recommeded in the catter condition. On the severe patients complicated by cholangitis, ultrasound-guided percutaneous transcystic external drainae may be performed before definitive opra-tion. When excision of the distal end of the cyst is difficult, the Saing's method oi endocystic excision is useful. Among the methods of reconstruct-ruction of qile duct, the Roux-en-Y hepaticojejunostomy is easier and more reliable than the short jejunal segment hepatico-duodenal interposition.
