[Progress and problems in pediatric surgery--a study group on congenital biliary atresia].
Japanese Study Group on Biliary Atresia was founded to make a standard classification of biliary atresia in 1975. The proposal of a new classification was made in the second meeting. Since then, annual meetings have been held to promote studies on biliary atresia. Various results have been obtained as follows: The diagnosis has been made more easily and accurately by use of new methods. As the operation have been performed more securely, the incidence of the disappearance of postoperative jaundice has risen to 80 percent, and more than 30 percent of the patients have been surviving for a long time. The patients who have had good outcome by the revision of the anastomosed region have increased. The endoscopic embolisation therapy was applied for the patients with postoperative esophageal varices. Various procedures preventing postoperative ascending cholangitis have been developed but there are no methods to prevent this complication completely. So the treatment of the ascending cholangitis remains one of the most important problems to be dissolved.
