The antegrade puncture technique represents a new approach to percutaneous transhepatic cholangiography andbiliary drainage. With this technique, ductal puncture begins with the liver capsule toward the hepaticparenchyma. This report briefly describes this new technique, and its safety and feasibility.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

A bronchobiliary fistula is rare disorder, consisting of the abnormal communication between the bronchial tree and the biliary duct. We describe a 78-year-old man who had a bronchobiliary fistula caused by choledocholithiasis. The diagnosis was confirmed by the presence of bilioptysis (bile-stained sputum) and the percutaneous transhepatic cholangiography (PTC). The patient was treated successfully by percutaneous transhepatic biliary drainage (PTBD) with stone extraction and was followed by healing of the bronchobiliary fistula without surgical intervention.

BACKGROUNDS AND STUDY AIMS: Multiple biliary papillomatosis (MBP) is an uncommon disease. This study was undertaken to review cases with respect to describing clinical features and characteristical cholangiographic findings, and to define the role of cholangioscopy in the diagnosis and treatment of this disorder. PATIENATS AND METHODS: from 1990 to 1997, nine patients (mean age; 57.3 years, 6 men and 3 women) were diagnosed as having MBP arnong 5,361 cases of endoscopic retrograde cholangiography (ERC) conducted at our center. A retrospective analyses of the cholangiographic and cholangioscopic findings as well as clinieal features were performed.

A choledochocele is a benign cyst-like herniation of the intramural segment of the distal common bile duct protruding into the duodenal lumen. Cholangiography is essential to demonstrate a choledochocele. Because choledochoceles are often associated with characteristic structual alterations of the papilla of Vater and the peripapillary area, ERCP is helpful in demonstrating a choledochocele. We present the clinical, endoscopic and radiographic (ERCP) findings in a patient with choledochocele.

BACKGROUND: Extrahepatic bile duct stones can be classified into two types. Primary stones are formed de nevo in the bile duct, whereas secondary stones migrate from the gallbladder into the bililary tree. The differentiation between primary and secondary stones is very difficult before operation. The aim of this study is to determine the origin of extrahepatic bile duct stones by analyzing MRC features. METHODS: MRC was obtained in 38 patients with stones in both the common duct and gallbladder. MRC findings were compared for gross characteristics and MR signal patterns between common duct stone and gallbladder stone pairs. The gross morphologic characteristics of gallstones on MRC were classified into oval, polygonal, round, rod, sandy and mixed shape. Gallstone patterns seen on heavily T2-weighted images were categorized into one of two patterns: dark, and mixed signal. RESULTS: According to the morphologic characteristics on MRC images, the common duct stones were oval (n=9), polygonal (n=15), round (n=6), sandy (n=4), mixed (n=3) and rod (n=1). The visualized MR signal patterns of common duct stones on heavily T2-weighted images were dark (n=28) and heterogenous (n=10). CONCLUSION: On MRC, the gross morphologic characteristics and gallstone patterns of common duct stones were similar to those of their paired gallbladder stones in 60.5 to 78.9% of patients.
