Background: Since seventeen employees of an offset printing company in Osaka, Japan developed cholangiocarcinoma it has become recognized as an occupational cancer. This study investigated the differences of clinical features between occupational cholangiocarcinoma and sporadic young-onset cholangiocarcinoma. Materials and Methods: Thirty-four young adults (<50 years old) with sporadic cholangiocarcinoma were extracted from the Rosai Hospital Group database (sporadic group) and their clinical features were compared with those of 17 patients with occupational cholangiocarcinoma (occupational group). Results: The 34 patients in the sporadic group were treated for cholangiocarcinoma at 16 different Rosai hospitals. There were significant differences of age (p<0.01), gender (p<0.01), abnormal laboratory tests (p<0.01), and tumor location (p<0.01) between the two groups. The percentage of patients with abnormal laboratory tests was significantly higher in the occupational group than in the sporadic group (p<0.001). Regional dilation of bile ducts, which is a characteristic of occupational cholangiocarcinoma, was not observed in the sporadic group. Conclusions: No cluster of cholangiocarcinoma cases was identified in the Rosai Hospital database. There were differences of clinical features between occupational and sporadic cholangiocarcinoma, which might be helpful for diagnosing occupational cholangiocarcinoma in the future.

Caroli's disease is a non-obstructive dilatation of the intrahepatic bile ducts. It is a rare congenital disorder that classically causes saccular ductal dilatation, which usually it segmental dilatation. Caroli's disease is associated with recurrent bacterial cholangitis and stone formation. A 57 years-old female inpatient suffering from cholangitis due to Caroli's disease was admitted at Wonkwang University Jeonju Oriental Medicine Hospital. The patient was treated with herbal medicine such as Yongdamsagan-tang and acupuncture. As result, there was improvement of symptoms. The process and content of treatment and the patient's recovery over general symptoms is described.

The livers of 300 cases of Korean native cattle which were collected at slaughted house in Pusan were examined by gross and histopathological means to study patterns of pathological changes of the organ. 1. The most dominated lesion of the liver was those of fascioliasis showing incidence rate as 907 per cent of inspected cattle. 2. On age distribution of the fascioliasis lesion in the liver, higher incidence was seen in animals that were from 6 to 9 years of age. 3. Significant changes of the hepaticparenchyma caused by immature flukes included thrombosis, migrational tracks such as hemorrhagic foci with massive eosinophilia and hepatic necrosis. The changes of chronically infected livers of cattle were recognized as proliferation of periductal eosinophilic granuloma of various degrees in each portal triad. And this easential cholangiohepatitis might develop into multiple focal cirrhosis or diffuse perilobular cirrhosis. 4. Most cases with gross lesion of swelled bile ducts on visceral surface of the liver showed histological evidences of fascioliasis lesion throughout hepatic lobes.

In order to clarify the histopathological changes resulting from nitrate poisoning, rabbits were experimentally poisoned by the oral administration of $KNO_3$ or $NaNO_2$ and examined clinically and histopathologically. In addition, the quantitative changes of glycogen level in hepatic cells were histochemically observed. The results obtained were summarized as follows: 1. Clinical symptoms observed from the acute cases which died within 2 hours after the administration were severe cyanosis of visible mucosa, frequent urination, and dyspnea. However, in chronic cases administrated daily with $KNO_3$ for 43, 50 and 74 days respectively, no marked symptoms were observed. 2. Macroscopic changes observed in acute cases were severe methemoglobinemia, cloudy swelling of hepatic cells, hemorrhage and hyperemia of gastric mucosa, and hyperemia of other organs. In chronic cases there were marked hyperemia, dark-red coloring and increasing of consistency in liver and kidney, and swelling of spleen. 3. Microscopic changes observed in acute cases were hemorrhage and hyperemia of various organs, cloudy swelling and centrilobular necrosis of hepatic cells and necrosis of convoluted tubular epithelium in kidney. In chronic cases there were round cell infiltration of the interlobular connective tissue and epithelial proliferation of interlobular bile ducts in the liver, and necrosis of the convoluted tubular epithelium and proliferation of interstitial connective tissue in kidney, thickening of alveolar septa of lungs, activated hemopoiesis of bone marrow, and myeloid metaplasia of sqlenic pulp. 4. Glycogen storage in liver cells was decreased in acute cases, on the contrary, increased in chronic cases.

Biliary atresia (BA) is the result of fibrosing destructive inflammatory process affecting intrahepatic and extrahepatic bile ducts, which lead to cirrhosis and portal hypertension. Kasai portoenterostomy has been the standard operative procedure in biliary atresia. Recently, there has been remarkable increase in the survival rate in cases of BA. However, long-term survivors are not clearly evaluated in Korea. To define long-term prognosis factors of patients who underwent surgery for BA, a retrospective study was undertaken of 10 (37 %) patients surviving more than 10 years among 27 patients who underwent one of Kasai procedures between 1981 and 1995. Hepatomegaly was present in 4 and splenomegaly in 7 patients. Serum bilirubin was normalized at 1 year after operation. Aspartate aminotransferase (AST, GOT), Alanine aminotransferase(ALT, GPT) were normalized at 12 years and alkaline phosphatase(ALP) was normalized at 13.5 years. Cholangitis developed mainly within 5 years after operation so close follow up is needed. Life long follow-up is needed because of progressive deterioration of liver function even after 10 years.

An 18-year-old woman with annular pancreas and duodenal duplication presented with recurrent acute pancreatitis and underwent a resection of duodenal duplication. However, the patient experienced recurrent abdominal pain after resection. Abdominal computed tomography and magnetic resonance imaging showed a dilatation of the peripheral pancreatic duct and stenosis and malformation of both the Wirsung's and Santorini's duct due to multiple stones. The modified puestow procedure was performed. The main pancreatic ducts in the body and tail were opened, and the intrapancreatic common bile duct was preserved. A Roux-en-Y pancreatico-jejunostomy was performed for reconstructing the pancreaticobiliary system after removing the ductal protein plug. The patient experienced no abdominal pain, no significant elevation of the serum amylase and lipase levels, and no stone formation during the 2 years of follow-up. This procedure is considered to be beneficial for pediatric patients with chronic pancreatitis due to annular pancreas and duodenal duplication.

When jaundice persists for more than 14 days postnatally, the early diagnosis of surgical jaundice is important for the prognosis in extrahepatic biliary atresia after draining procedure. The role of diagnostic laparoscopy to differenctiate medical causes of jaundice from biliary atresia is evaluated in this report. Four patients with prolonged jaundice have been included in this study. When the gallbladder was not visualized we proceeded to laparotomy. In patients with enlarged gallbladder visualized at laparoscopy, laparoscopic guided cholangiogram was performed, and laparoscopic liver biopsy was done for those who had a patent biliary tree. Two patients had small atretic gallbladder and underwent a Kasai hepato-portoenterostomy. One patients showed a patent gallbladder and common bile duct with atresia of the common hepatic and intrahepatic ducts, and they underwent a Kasai hepatic-portoenterostomy. One patient showed an enlarged gallbladder and laparoscopic-guided cholangiogram were normal. Laparoscopic liver biopsy was performed. There were no complications. Laparoscopy with laparoscopic-guided cholangiogram may be a valuable method in accurate and earlier diagnosis in an infant with prolonged jaundice.

Clonorchiasis, caused by direct contact with Clonorchis sinensis worms and their excretory-secretory products (ESPs), is associated with chronic inflammation, malignant changes in bile ducts, and even cholangiocarcinogenesis. Our previous report revealed that intracellular free radicals enzymatically generated by C. sinensis ESPs cause NF-${\kappa}B$-mediated inflammation in human cholangiocarcinoma cells (HuCCT1). Therefore, the present study was conducted to examine the role of upstream Toll-like receptors (TLRs) on the initial host innate immune responses to infection. We found that treatment of HuCCT1 cells with native ESPs induced changes in TLR mRNA levels in a time-dependent manner, concomitant with the generation of free radicals. ESP-mediated free radical generation was markedly attenuated by preincubation of the cells with TLR1-4-neutralizing antibodies, indicating that at least TLR1 through 4 participate in stimulation of the host innate immune responses. These findings indicate that free radicals triggered by ESPs are critically involved in TLR signal transduction. Continuous signaling by this pathway may function in initiating C. sinensis infection-associated inflammation cascades, a detrimental event leading to progression to more severe hepatobiliary diseases.
