54 patients who had symptoms after biliary operation were studied by $^{99m}Tc-DISIDA$ hepatobiliary scintigraphy for evaluation of clinical utility, with regional emphasis of recurrent pyogenic cholangitis (RPC) and intrahepatic stones. As expected, the most common disease was recurrent pyogenic cholangitis regardless of surgical anastomosis, 58% and next frequent disease was clonorhis sinensis infestation, 26%, stenosis of ampula vater 8%, and chronic hepatitis 4% (20% of patients had hepatitis but they showed clinically and scintigraphically dominallt combined disease feature). 87% of recurrent pyogenic cholangitis was associated with stones in intra or/and extrahepatic ducts and only 11.4% of RPC was found to be associated with Cs-infestation. The scintigraphic diagnosis of RPC was 81.6% and 78.6% of stones was detected by indirect visualization of scintigraphy findings and 71.7% of Cs-infestation was detected by scintigraphy. The characteristic bile flow pattern were described.

Isolated pancreatic trauma and secondary obstructive jaundice in the pediatric population is unusual. Biliary tract obstruction can be a major cause of acute pancreatitis. We report a case of obstructive jaundice secondary to isolated traumatic acute pancreatitis in a previously healthy 32-month-old girl. In our case, secondary obstructive jaundice aggravated the pancreatic inflammation and was successfully treated with percutaneous transhepatic biliary drainage (PTBD).

A 43-year-old Korean woman with billary ascariasis accompanied by cholellthiasis is reported. Her chief complaints were abdominal pain, nausea, and vomiting. She had the past history of several attacks of abdominal pain in her childhood. ciliary stones were recovered from the left hepatic duct after cholecystectomy, which contained degenerated cuticle or body wall, and numerous eggs of Ascaris lumbriooides. It is strongly suggested that the ciliary stones were formed from the dead Ascmis worm(s). This is a rare case of biliary ascariasis during the recent 5 years in Korea.

Purpose: The aim of the present study was to evaluate the long-term clinical profile including the underlying etioligy and the prognostic factors of the neonatal cholestasis. Method: We studied the 190 infants presented with neonatal cholestasis for the last 12 years (from 1981 to 1992). The underlying causes, clinical findings and long-term outcomes were evaluated. And the prognostic factors were also analyzed. Result: Underlying disease were neonatal hepatitis in 101 (idiopathic in 77 and infectious in 24), intrahepatic bile duct paucity in 5, biliary atresia in 79, choledochal cyst in 5. Metabolic disease was not observed in this study. The important clinical problems during follow-up were persistent high fever, gastrointestinal bleeding, hepatic encephalopathy and ascites. The main causes of the death were hepatic encephalopathy and gastrointestinal bleeding. While three fourth of infants with idiopathic and infectious neonatal hepatitis recovered usually within a year, five-year survival rate for biliary atresia was just 40%, the mortality observed usually within the first year after Kasai operation and prognostic factor was the time of operation. Underlying disease was the most important prognostic factor of neonatal cholestasis. Conclusion: This study showed that most common causes of neonatal cholestasis were biliary atresia and idiopathic neonatal hepatitis, infectious neonatal hepatitis, choledochal cyst and Alagille syndrome, but few neonatal cholestasis of genetic or metabolic liver disease was observed. The most important long-term prognostic factor of neonatal cholestasis was the underlying disease.

Purpose : Magnetic resonance cholangiopancreatography(MRCP) is a noninvasive method for imaging the pancreaticobiliary tree. The aim of this study was to evalute the usefulness of MRCP for the diagnosis of pancreaticobiliary diseases in children. Methods : From October 1996 to May 2001, 67 patients with obstructive jaundice and three patients with chronic recurrent pancreatitis were evaluated with abdominal ultrasonography and MRCP. The final diagnosis was based on the operative and pathologic findings with biopsy specimen including clinical and laboratory findings. Results : A total of 70 patients, consisting of 31 males and 39 females, with a mean age of $2.6{\pm}3.3$ years were studied. The final diagnosis was biliary atresia in 25, neonatal cholestasis in 18, choledochal cyst without anomalous pancreatobiliary duct union(APBDU) in nine, choledochal cyst with APBDU in seven, cholestatic hepatitis in five, chronic recurrent pancreatitis in three, sclerosing cholangitis in two, and secondary biliary cirrhosis in one case. The overall diagnostic accuracy of abdominal ultrasonography was 75.7% and that of MRCP was 97.1%. The sensitivity and specificity of MRCP were 100% and 98% for biliary atresia, 87.5% and 100% for choledochal cyst with APBDU, 100% and 100% for choledochal cyst without APBDU, sclerosing cholangitis and chronic recurrent pancreatitis, respectively. Conclusion : MRCP is a fast, non-invasive and reliable method for diagnosing pancreaticobiliary diseases in children and will be the standard diagnostic procedure in the future.

While various examples of rationale or benefits of ascariasis control could justify a necessity of control activity in a community, few practical index other than the e99 Prevalence or intensity of infection has been used to evaluate the efficacy obtained by the control activity. A literature-based retrospective study was undertaken to provide some numerical data on the decreasing morbidity of surgical ascariasis as a consequence of ascariasis control in Korea. A thorough review of literatures (1959∼1990) on biliary and other surgical complications of ascariasis reported from general hospitals revealed that their incidence has been decreasing very proportionally to the national figures of its e99 Prevalence and worm burden. For example, according to the remarkable decreases of the prevalence of ascariasis, there is an evident decreasing tendency of the proportion(%) of ciliary ascariasis cases among all biliary surgical patients and the proportion of biliary ascariasis cases among all biliary stone patients in general hospitals. It is highly suggested that the Korean people have been much benefited by the control activity of ascariasis executed at a national scale since 1960s, especially in terms of incidence of biliary and other surgical complications of ascariasis.

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.

Purpose :To analyze the survival period, prognostic factors and complications of patients having undergone high-dose-rate intraluminal brachytherapy (HDR-ILB) as a salvage radiation therapy, while having a catheter, for percutaneous transhepatic billary drainage (PTBD), inserted due to biliary obstruction caused by a secondary malignant biliary tumor Methods and Materials : A retrospective study was performed on 24 patients having undergone HDR-ILB, with PTBD catheter Insertion, be)ween December 1992 and August 2001. Their median age was 58.5, ranging from 35 to 82 years. The primary cancer site were the stomach, gallbladder, liver, pancreas and the colon, with 12, 6, 3, 2 and 1 cases, respectively. Eighteen patients were treated with external beam radiation therapy and HDR-lLB, while slx were treated with HDR-lLB only. The 4otal external beam, and brachytherapy radiations dose were 30$\~$61.2 and 9$\~$30 Gy, with median doses of 50 and 15 Gy, respectively. Results : Of the 24 patients analyzed, 22 died during the follow-up period, with a median survival of 7.3 months. The 6 and 12 months survival rates were 54.2 (13 patients) and 20.8$\%$ (5 patients), respectively. The median survivals for stomach and gailbladder cancers were 7.8 and 10.2 months, respectively, According to the unlvariate analysis, a significant factor affecting survival of over one year was the total radiation dose (over 50 Gy) (o=0.0200), with all )he patients surviving more than one year had been Irradiated with more than 50 Gy. The acute side effects during the radiation therapy were managed with conservative treatment. During the follow-up period, 5 patients showed symptoms of cholangltis due to the radiation therapy Conclusion :An extension to the survival of those patients treated with HDR-ILB is suggested compared to the median historical survival of 4hose patients treated with external biliary drainage. A boost radiation dose could be effectively given, by performing HDR-lLB, which is a prognostic factor In addition, the acute complications of radiation therapy were effectively controlled by conservative management, and It could be regarded as a safe treatment.

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.
