小児用十二指腸ファイバースコープの開発と臨床応用

抄録

During the period from 1975 to 1981, endoscopic retrograde cholangio-pancreatography (ERCP) has been attemted for 48 times in 45 infants and children, resulting in successful cannulation in 36 patients. The patients age ranged from 35 days to 15 years. Sixteen patients were congenital choledocal dilatation and various types such as, anomalous junction of pancreatico-biliary ductal system without choledocal dilatation, cholecystolithiasis, infantile hepatitis, pancreatitis, traumatic pancreas injury, Alagilles syndrom and 5 were congenital biliary atresia. In 6 patients, no abnormality was found. The overall success rate in cannulation was 75%. Three types of duodenoscopes, JF-B_2 (Olympus Co.), FGS-PE_a (Machida Co.) and XPJF (Olympus Co.) were employed. FGS-PE_2 and XPGF are the newly designed duodenoscopes for pediatric patients. FGS-PE_2 has been developed in co-operation with our department. The outer diametr of FGS-PE_2 and XPJF are 8.0 and 8.8mm respectively. These two new products of FGS-PE_2 and XPJF, have been available since 1980. Since then, success rate in cannulation has been improved to 100%, including 8 patients under 100 days of age. We have found that these two new duodenoscopes specially designed for pediatric patients are quite useful for ERCP in Infants and Children.
