Abstract
Two cases of cholelithiasis in children were reported. [Case l] A 2 year and 2 month old boy was admitted with upper abdominal pain and vomiting. The levels of liver and biliary enzymes were high. He was diagnosed as cholecystolithiasis by abdominal ultrasonography. On ERCP examination, cystic duct was mostly parallel to common hepatic duct and gallbladder was displaced to-ward porta hepatis i. e. "transeverse position of gallbladder". He had neither choledocholithiasis nor anomalous pancreaticobiliary ductal union. Cholecystectomy was performed and a stone of body in gallbladder and a stone of cystic duct were found. These stones were made of bilirubin. The patient is active and well at one year and nine months after surgery. [Case 2] A 4 year and 2 month old boy was admitted with abdominal pain and vomiting. On abdominal X-ray study, four calcifications of bean size were found at right side of 1st lumbar vertebra. Anomalous pancreaticobiliary ductal union didn't exist on ERCP examination. Intraoperative cholangiography revealed neither intrahepatic stone nor choledocholithiasis. Cholecystectomy was carried out and four stones made of calcium carbonate were fonud in gallbladder. The patient is active and well at five months after surgery.
