Endoscopic Retrograde Cholangiopancreatography (ERCP) Performed in Children Y. Urakami, H. Seki, S. Kishi 2nd Department of Internal Medicine, School of Medicine, Tokushima University, Japan

Summary

The value of ERCP in children is demonstrated on 3 cases. By using a usual duodenofiberscope (JF-B2), in 2 cases under general anesthesia and in one case after premedication with 1 ml Buscopan® i.m., a similar technique is used as in adults. In congenital choledochal cyst only ERCP

allowed the exact judgement of the distal part of the common bile duct and its relation to the pancreatic duct. Therefore, an exact preoperative

diagnosis can be established. When duodenofiberscope will be more improved ERCP will also be possible in the newborn infant. Than the differential diagnosis of congenital biliary atresia, other congenital failures in infants causing jaundice and hepatitis in infant will be established endoscopically.

Endoskopische retrograde Cholangiopankreatographie (ERCP) bei Kindern

An 3 Fallen wird der Wert der ERCP bei Kindern demonstriert. Unter Verwendung eines üblichen Duodenoskops (JF-B2) wurde bei 2 Fallen in Narkose und bei einem Fall nach Pramedikation mit 1 ml Buscopan i. m. eine ERCP nach der bei Erwachsenen üblichen Technik durchgeführt. In Fallen von kongenitaler Choledochuszyste erlaubt nur die ERCP eine exakte Beurteilung des distalen Ductus choledochus und seine Beziehung zum Ductus pancreaticus. Dadurch kann eine exakte praoperative Diagnose gestellt werden. Durch Verbesserung der Duodenoskope wird es auch möglich sein, die ERCP bei Neugeborenen durchzufiihren. Dann kann auf diese Weise eine

cholangiography revealed a dilatation of the left hepatic and common bile duct. The gallbladder appeared normal (Fig. 1). A congenital dila-

tation of the biliary tract was considered from this findings. To receive exact information about

the duct system ERCP was attempted using JF-B, under general anesthesia. The dilatation of the left hepatic and common bile duct were confirmed and furthermore it was demonstrated that the distal common duct was narrowed (Fig. 2). An abnormal connection between the common bile duct and the pancreatic duct was shown (Figs. 3 and 4). Exstirpation of the cyst and hepatojejunostomy (Roux en Y anastomosis) was performed. Case 2: A 8-years-old girl of 22 kg body weight complained of recurrent colic pains in the upper

abdomen. Laboratory findings showed a slight

To clarify the diagnosis ERCP was performed under general anesthesia using JF-B2. The cystic structure of the extrahepatic bile duct and dilatation of the intrahepatic biliary tree was confirmed. Additionally to this findings it was proven that the distal common bile duct was narrowed (Fig. 7, and 8). The pancreatic duct was not visualized. As the result of ERCP a congenital cystic dilatation of the bile duct was diagnosed. Exstirpation of the cyst and hepatojejunostomy (Roux en Y anastomosis) was performed.

Case 3: The chief complaints of a 13-years-old boy were epigastric pain and abdominal discomfort. By physical examination a tumor was palpable in the upper abdominal region. Upper GI series showed a displacement of the stomach by a large mass to the lateral and anterior portion.

The greater curvature of the antrum and the duodenal bulb also were deformed. On the posterior wall of the gastric body a wallnutsized-submucosal tumor with central ulceration was seen. From this findings a retroperitoneal tumor was considered. ERCP performed only after premedication of Buscopan 1 ml i.m, and local anesthesia with Xylocain-Spray, revealed numerous areas of narrowing and dilatation diffusely scattered throughout the pancreatic duct. The common bile duct was partially visualized (Fig. 9).

Discussion

Our experiences on 3 children show that ERCP can be performed in the same way

and by the same technique as in adults. Especially in cases of congenital choledochal

cysts this method is superior to all other
