BACKGROUND/AIMS: The biliary tract often shows various morphologic abnormalities. Thus various anomalies and variations of the cystic duct have been extensively studied via cadeveric or intraoperative dissections and operative cholangiograms. The knowledge of the junction of cystic and common hepatic duct is essential for endoscopic management of biliary tract disease. But no large series identifying this critical cystico-hepatic junction(CHJ) by duodenoscopy has been reported. METHODS: To know the anomaly and variant of CHJ and to evaluate its clinical significence, we retrospectively reviewed 434 cases of endoscopic retrograde cholangiography performed at Korea University Hospital from 1992 through 1993. The CHJ was categorized as lateral or medial only for unequivocal angulation in that direction, and spiral when there is overlap of the CHJ with the bile duct in the posteroanterior view. The CHJ was further modified as parallel if the course of the two ducts was closely adherent for 1 cm or more. In addition to identifying the radial takeoff, the level of the CHJ along the length of the extrahepatic biliary tree was determined. The distance from the ampulla to the junction was divided by the distance from the ampulla to the bifurcation and expressed as proximal, middle, distal, respectively. RESULTS: The level of CHJ was mainly middle in 68.4% followed by distal in 16.4%, prximal in 15.2%. The radial orientation of CHJ was mainly lateral in 51.6%, followed by spiral in 32.3%, medial in 16.1%. The cystic duct runs parallely in 11.5%, mainly in the distally inserted, medially oriented cystic duct. The incidence of abnormalous CHJ was 5 case(1.2%), which included 1 case of cystic duct entering the right hepatic duct, 3 case of cystic duct entering at the junction of both extrahepatic duct(trifurcation), and 1 case of accessory hepatic duct entering cystic duct. The most common biliary disease by ERCP was gallbladder stone(25.5%), followed by common bile duct stone(19.5%), intrahepatic duct stone(7.2%), cystic duct obstruction(4.5%), cystic duct stone(2.9%), and others(bile duct cancer, gallbladder cancer, Mirizzi's syndrome). According to the level of the CHJ, there were low incidence of gallbladder stone in distal CHJ, low incidence of common bile duct stone in proximal CHJ and high incidence of Mirrizi's syndrome and gallbladder cancer in distal CHJ. There were no difference in the incidence of biliary disease according to the radial orientation and course of the CHJ. Practically, during therapeutic ERCP there were some tdchnical difficulties in extraction of biliary stone or selective bile duct cannulation in the presence of distally inserted, parallel course of the cystic duct. CONCLUSIONS: The anatomy of the CHJ by ERCP is more variable than that of previous surgical and autopsy reports and the endoscopist should be aware of this variants for safe and effective intervention in bile duct disease.

BACKGROUND: Several studies have been reported that the presence of Helicobacter DNA in human bile sample, although its pathological role is not clear. The purpose of this study was to evaluate the presence and identification of Helicobacter species in human bile samples obtained from patients with biliary tract diseases. METHODS: 58 bile samples (35 intrahepatic duct stones, 10 bile duct cancer, 13 pancreatic cancer) were obtained by percutaneous transhepatic biliary drainage (PTBD). DNA was isolated from bile sample. The primers were designed to amplify region of Helicobacter genus specific 16S rRNA. Polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) was developed to differenciate the presence of H. pylori, H. bilis, H. rappini and H. muridarum. RESULTS: Forty-two of 58 (72.4%) bile samples obtained from patients with biliary tract disease showed positive PCR band for Helicobacter genus specific 16S rRNA. H. pylori was found in 83.3% of positive samples. Either H. bilis or H. rappini was in 16.7%. H. muridarum, however, was not detected. CONCLUSION: Helicobacter genus was detected in human bile samples obtained from patients with biliary tract diseases using PCR method, and the major species was H. pylori. In addition, RFLP technique was used successfully to identify Helicobacter species.

BACKGROUND : Anomalous pancreaticobiliary ductal union (APBDU) is a congenital defect defined as a union of the pancreatic and the biliary ducts located outside the duodenal wall. Accordingly, this anomalous connection between the choledochus and the pancreatic duct is considered to be a factor in the development of biliary tract diseases such as choledochal cysts, pancreatitis, cholangitis, gallbladder cancer, and bile duct cancer. Our purpose is to analyze combined disease, especially biliary neoplasm, and to evaluate biliary tract microscopic changes in the biliary tract. METHODS : To study the clinical characteristics of APBDU, we reviewed 21 APBDU cases which were treated from June 1994 to January 1998. We studied the associated diseases, the surgical treatment, histological findings and the PCNA expression. We also analyzed the gallbladder epithelium in 10 control patients without APBDU. RESULTS : Among the 21 cases, 12 cases were accompanied by a choledochal cyst. A gallbladder carci noma occurred in 5 cases. Of the 13 operations, 4 involved a cholecystectomy only, and 9 involved a cholecystectomy, bile duct resection and hepaticojejunostomy. The histologic findings were reviewed in 13 cases. Bile duct metaplasia was found in 8 of the 9 cases with a bile duct resection, and gallbladder metaplasia was found in 8 of the 12 cases whereas metaplasia was detected in 1 of the 10 control patients. The PCNA expression was significantly high in APBDU group. CONCLUSIONS : The patients with APBDU showed a high incidence of gallbladder carcinoma and meta plasia in the epithelium of the gallbladder and the bile duct. This metaplasia in the gallbladder and the bile duct was thought to be related to the cancerous change.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is difficult to perform in patients with a Billroth II anastomosis due to the anatomical alterations. This study evaluated retrospectively the efficacy and safety of endoscopic balloon dilatation after a partial infundibulotomy with a needle knife in patients who had undergone a Billroth II operation. METHODS: Between January 1, 2004 and December 31, 2005, 11 patients, who had undergone a prior Billroth II gastrectomy, underwent ERCP because of a suspicion of pancreatobiliary diseases. Infundibulotomy was performed using a needle knife sphincterotome. After a partial infundibulotomy, a dilation balloon was passed over a prepositioned guidewire and placed in the biliary orifice. Under endoscopic and fluoroscopic control, the balloon was then inflated with diluted contrast over a period of 1 to 2 minutes. RESULTS: A total of 10 patients (7 male and 3 female) were enrolled in this study. Eight had common bile duct stones, 1 bile duct cancer, and 1 pancreatic cancer. The common bile duct was dilated by a balloon. The calculi were removed in 6 patients, and a common bile duct stent was implanted in two cases via endoscopy. No complications such as acute pancreatitis or apparent infections of the biliary tracts were encountered in these cases except for mild fever, temporary high serum levels of aminotransferase and amylase after ERCP in 3 cases. No severe bleeding or perforation occurred in patients undergoing balloon dilatation. CONCLUSIONS: An infundibulotomy with balloon dilatation is a valuable alternative to endoscopic sphinterotomy in the treatment of patients with bile duct diseases, who have undergone prior Billroth II gastrectomies.

To assess the reproducibility of Sphincter of Oddi(SO) manometry, percutaneous manometry of SO was performed repeatedly in 10 subjects with biliary diseases(9 intrahepatic stone cases and 1 bile duct cancer case). Time interval for measurement of SO manometry was 3 to 7(mean 5) days. Mean manometric parameters of SO phasic contraction in the 1st and 2nd studies were not significantly different. However, as a result of manometric records, a diagnosis of dyskinesia was made in the 1st study from 4 patients(tachyoddia in 3 cases and increased retrograde propagation in one case). Among them, the diagnosis was reproduced in the 2nd study from 2(tachyoddia in 2 cases) out of 4 patients. In conclusion, abnormal manometric findings were poorly reproducible. Thus, more prolonged measurement of SO manometry or a dynamic test which stimuli or inhibit the SO activity may be necessary for accurate diagnosis of biliary dyskinesia and better reproducibility of SO manometry.

Extramedullary plasmacytoma is a rare disease that is histopathologically defined as a solitary tumor composed of a monoclonal proliferation of cells with plasmacytic differentiation in an extramedullary site. Most of these tumors occur in the submucosa of the upper aerodigestive tract, and they rarely occur in the small bowel mesentery. We report here on a case of extramedullary plasmacytoma of the small bowel mesentery that was in association with a cecal cancer. Abdominal ultrasound and CT revealed a lobulated soft tissue mass with a cystic portion and peripheral calcification. In this case, the preoperative radiological diagnosis was difficult due to accompanying cecal cancer.

The diagnostic accuracy of percutaneous transhepatic cholangioscopy (PTCS) was compared to that of three radiologic modalities in distal common bile duct (CBD) strictures for the evaluation of clinical application. Ninety-five patients who underwent PTCS for the evaluation of distal CBD strictures (35 malignant and 60 benign) whose masses were not obvious from radiologic imagings were included. Confirmative diagnosis could not be reached by endoscopic retrograde cholangiopancreatography (ERCP) or radiologic findings in all cases. Specific findings on the computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) and direct cholangiography were analyzed among 68 (25 malignant and 43 benign) out of the 95 patients in order to determine the sensitivity and specificity of three radiologic studies for the diagnosis of malignant distal CBD strictures, and to compare those results with those by a combination of PTCS-guided biopsy and tumor vessel observation on cholangioscopy. The sensitivity/specificity of CT, MRCP and direct cholangiography including ERCP in diagnosing malignant distal CBD strictures were 42.9%/65.8%, 53.3%/58.3%, and 70.8%/47.6% respectively, while it was 96%/100% for the combination of PTCS-guided biopsy and tumor vessel. PTCS is a useful method for differential diagnosis of distal CBD strictures, particularly when it is difficult to distinguish benign from malignant strictures by radiologic studies and when peroral approach is not feasible.

Biliary drainage in patients with malignant biliary obstruction relieves jaundice and prevents the development of cholangitis or hepatic failure from biliary obstruction. Therefore, this may result in better quality of life along with survival prolongation. Biliary stent placement is an effective and safe measure for biliary decompression and is preferred than bypass surgery in high risk patients. Entero-biliary perforation-communication is one of the rare complications of biliary stent. We herein report a case of duodeno-biliary perforation-communication in patient with distal cholangiocarcinoma who presented with duodenal ulcer and obstruction, occurring 4 years later from the metallic biliary stent insertion. Patient was managed with a pyloric metal stent and conservative care.
