Biliary cast syndrome is an unusual complication in patients who have previously undergone liver transplantation. It occurs in approximately 5%-18% of such patients. Rare cases of biliary cast syndrome in patients without liver transplants have also been reported. The pathogenesis of biliary cast has not been clearly identified, although etiologic factors including post-transplant bile duct damage, ischemia, biliary infection, and presence of a post-operative biliary drainage tube have been proposed. Here we present a case of biliary cast that developed in a 49-year-old male who underwent a non-liver surgery after endoscopic and percutaneous management of common bile duct stone.

Background/Aim : Common bile duct (CBD) stones may cause jaundice, cholangitis, or pancreatitis. Extracorporeal shock wave lithotripsy (ESWL) may be needed whenever endoscopic procedure are failed to extract common bile duct stones. The aim of this study is to provide the standard for patient's best choice on ESWL for treatment of CBD stones resistant to endoscopic extraction. Materials and Methods : Fourty-six patients failed in endoscopic stone extraction including mechanical lithotripsy were treated by ESWL. In all patients, endoscopic sphincterotomy and nasobiliary drainage tube was done before ESWL using the ultrasonography for stone localization with a spark-gap type lithotriptor. Patients were sedated with an intravenous injection of 50 mg of Demerol. None were treated under general anesthesia. Results : Overall complete clearance rate of CBD stone was 89.1% (41/46). In 82.6% of the patients, the stones were extracted endoscopically after ESWL, and spontaneous passage was observed in 6.5%. In the clearance rate after ESWL, there were no noticeable differences with regard to number (single: 82.8%, two or three: 100%, more than three: 100%) and size of the stone (less than 33mm: 92.9%, 33 mm or larger: 83.3%), whereas there were significant differences with regard to the ratio of sum of long-axis length of the all stones to sum of long-axis length of the CBD excluding stone (1:2.4, 1:2.1) and diameter of the largest stone to diameter of CBD excluding stone (1:0.9, 1:0.4) for patients with complete clearance compared with those without. Conclusion : We propose that stones without the fragments are travelable sufficient space in CBD or extractable sufficient diameter of CBD regardless of stone size and number should be treated by other technique to prevent time and cost consuming, such as percutaneous transhepatic cholangioscopylithotomy.

Background/Aims : Gallbladder(GB) stone is the most common disease in the biliary system, and the incidence is gradually increasing in Korea. This change may include rapidly proceeding urbanization and changing food factor. We performed this study to investigate related GB stones and contraction of GB as dietary factors. Methods : We investigated 129 subjects(mean age : 47 years). GB stone group is 9 subjects(M: 2, F: 7) in Namyangju-si. Control group without GB stone is 18 subjects(M: 6, F: 12) in Wi-do island. For subjects without GB stone, diabetes mellitus decide 4(M: 2, F: 2) and then each after eat flesh and meat of estimated by experimental group ejection fraction rate(%). Results : Ejection fraction rate of GB were different between meat and fishes intake. When ate the meat in experiment for hypothetical verification, when become ejection fraction rate of meal GB 210 minutes, was the highest and when ate fish, the ejection fraction rate of GB was the highest in meal 120 minutes. Conclusions : After meats intaking the bile inside the GB is stagnant long and the GB stone is formed. We studied the results GB motility may important play a role on GB stone formation.

Background/aim : Gallbladder stone is the most common disease of biliary tract. It is lead to acute abdominal pain. The cholecystitis which is caused by in gallbladder stone occurs frequently and the possibility of the gallbladder cancer comes to be high. Our study was designed to determine the prevalence and risk factors gallbladder stone in a population who community. Materials and Methods : We enrolled a total of 826 (male : 297, female : 529) persons who 60 or older in Jeju-do 10 places from 2008 July one months. The height, weight, liver function tests, lipid profile, fasting blood sugar, were all measurement. They had their gallbladder examined with using ultrasonography. Statistical significance was defined as a p-value less than 0.05. Results : Among 826 persons, gallbladder stone was found in 49 persons (5.9%). The male is 6.1% and the female is 5.8%, the male 1.03 times appeared more highly the female. The body mass index above of 23.0 kg/$m^2$ with the gallbladder stone was 69.3% (p<0.047). Conclusion : The gallbladder stone appeared highly according to age increases. The obesity is the risk factor of gallbladder stone. The weight management and diet control is a possibility of reducing a gallbladder stone creation.

Cholethorax (bilious pleural effusion) is an extravasation of bile into the thoracic cavity via a pleurobiliary fistula (and also a bronchobiliary fistula). It is an extremely rare complication of thoraco-abdominal injuries. It can be caused by congenital anomaly and also by hepatobiliary trauma, severe infection or iatrogenic procedures. The definitive diagnosis is made with aspiration of bilious fluid from the pleural space during thoracentesis, by finding a fistulous tract during endoscopic retrograde cholangiopancreatography (ERCP) or cholagioscopy, or with finding an abnormal pleural accumulation of radioisotope during hepatobiliary nuclear imaging. Its symptoms include coughing, fever, dyspnea and pleuritc chest pain. Herein we report on a case of cholethorax following performance of percutaneous transhepatic cholangioscopy (PTCS) to remove incidentally discovered common bile duct (CBD) stones.

Background: $Clonorchis$ $sinensis$ is an important human parasite that is usually found in the biliary tract. It is widely distributed in East Asia in Taiwan, Japan, China and Korea. About 2 million people are estimated to be infected with $C.$ $sinensis$ in Korea. This study was conducted to evaluate the state of infestation and clinical aspects of $C.$ $sinensis$. Material and Methods: We evaluate 1,063 patients with clonorchiasis retrospectively at Yeungnam University Hospital and Health Promotion Center from January 2001 to December 2003. All patients were diagnosed by a positive stool test for $C.$ $sinensis$ eggs. Clinical features, laboratory data and imaging studies were evaluated. Results: The ratio between affected males and females was 3.6 : 1. The highest infection rate was noted in the 40-60 age groups regardless of sex. The infection rate of $C.$ $sinensis$ among the residents of urban areas was higher than in rural areas. There were 813 (76.5%) patients who were asymptomatic. Common symptoms included right upper abdominal pain in 7.6% and epigastric pain in 7.2%. For the laboratory studies, serum ALP and GGT levels were within normal limits in 85.2% and 56.0% respectively. Peripheral eosinophilia was noted in 66.1% of cases. Of the 83 cases undergoing ERCP, 27 cases (32.5%) showed peripheral dilatation of the intrahepatic duct. Conclusion: This study suggests that $C.$ $sinensis$ infection is still endemic even in rural areas of Korea and that asymptomatic infections are common. Further work should be focused on the early diagnosis and treatment of patients with subclinical infection.

From the one hundred forty eight patients with evidence of biliary tract obstruction, 275 bile samples were obtained from percutaneously placed biliary drainage catheters. Of the 148 patients, ova of Clonorchis sinensis were demonstrated in 17 patients (11.5%), with the epithelial cells. Among them, one case also demonstrated coexisting adenocarcinoma. In 105 patients, the medical records were available for review and the clinical diagnoses were malignancy in 99 patients and benign lesion in 6 patients. Of the 99 patients in which clinico-radiologic diagnosis were malignant, cytologic results were positive in 23.2%. Dividing the patients Into two groups, the ones with tumor of bile duct origin (group I) and the others with tumors producing extrinsic compression of bile duct, such as periampullary carcinoma, pancreas head carcinoma or metastatic carcinoma in lymph nodes from tumors of adjacent organs (group II), the cytologic results were positive in 37% and 11.6%, respectively. In patients with histologic confirmation, the positive correlation was found in 50% and 20% in group I and group II, respectively, with remarkable difference between two groups. There were no false positives in cytologic diangosis. The overall concordance rate of cytologic diagnosis with diagnosis of clinical investigation in both benign and malignant lesions was 27.6% and the diagnostic specificity was 100%.

Purpose : To evaluate the usefulness of MRCP in the diagnosis of the variable causes of common bile duct(CBD) dilatation, except stone or tumor Materials and methods : Twenty-six patients(M:F=15:11, mean age; 62 years) with both MRCP and ERCP were included in this study. Dynamic MRCP(n=12) and contrast-enhanced MRI(n=10) of abdomen were also added. Dilatation of CBD, intrahepatic ducts and pancreatic duct was evaluated, including coexistence of intrahepatic ductal stone, pancreatic pseudocyst, and papillary or papillary edema. The criteria of CBD dilatation was over than 7mm(n= 21, without cholecystectomy) or 10 mm(n=5, with cholecystecto-my) in diameter on T2-weighted coronal image. Results : The mean diameter of CBD was 12.7mm without cholecystectomy(9-19 mm) and 13.0 mm with cholecystectomy(10-15mm), respectively(p 〉0.05). Cholangitis(n=11, 42.3%), chronic pancreatitis(n=8, 30.8%), stenosis of distal CBD(n= 6, 23.1%), periampullary diverticulum(n=3, 11.5%), stenosis of ampulla of Vater(n=2, 7.7%), dysfunction of sphincter of Oddi(n=2, 7.7%), acute focal pancreatitis in the pancreatic head(n=2, 7.7%), papillitis(n=1, 3.8%), pseudocyst in the pancre atic head(n = 1, 3.8%), and ascaris in CBD(n=1, 3.8%) were noted. Pancreatic duct dilatation(n=10, 38.5%) and duodenal diverticulum(n=3, 11.5%) were also seen on MRC P. On dynamic MRCP(12 patients), distal CBD was visualized in 2 patients(16.7%), which was not shown on routine MRCP. Only 1 patient(10.0%) showed papillitis with slightly enhancing papilla on contrast-enhanced MRI (10 patients). Conclusion : MRCP was thought to be helpful in the evaluation of the causes of CBD dilatation, not caused by stone or tumor, especially in the cases of stenosis of distal CBD and chronic pancreatitis, dysfunction of sphincter of Oddi on dynamic MRCP and cholangitis and pericholangitic abnormality on contrast-enhanced MRI.

A 69-year old man presented with severe epigastric pain for 1 day. He had early gastric cancer at the antrum and underwent a distal subtotal gastrectomy and Billorth II gastrojejunostomy one month later without any post-operative complications. Radiologic examination revealed a large amount of retroperitoneal free air formation. Because of unremitting pain and unstable vital sign, exploratory laparotomy was followed. During the operation, a perforated duodenal diverticulum at the posterior wall of the 2nd portion of the duodenum was identified. He underwent diverticulectomy and primary closure. He was discharged on the 18th post operative day and has been followed up without any evidence of comlpication for several months.
