Mucinous cholangiocarcinoma, characterized by large quantities of mucin production, is a rare subtype of peripheral cholangiocarcinoma and usually shows rapid progression and a fatal outcome. We report here a case of mucinous cholangiocarcinoma in a 69 year-old man, who was infected with Clonorchis sinensis. Histologically, the tumor was an adenocarcinoma with extensive intracellular and extracellular mucin production, up to 70% of the tumor mass and there was frequent lymphovascular invasion of the tumor cells. The liver adjacent to the mass contained eggs of Clonorchis sinensis in the bile duct lumen and showed ductal epithelial hyperplasia, mucinous metaplasia and adenomatous proliferation of intramural glands. The patient was treated with a right hepatectomy. Four months after the surgery, the tumor recurred in the soft tissue of the right flank.

2.A Bile Based Study of Clonorchis sinensis Infections in Patients with Biliary Tract Diseases in Ulsan, Korea.
Yonsei Medical Journal 2005;46(6):794-798
Stool examination is believed to be the most reliable method for detecting Clonorchis sinensis (CS) eggs. However, it has limited value for diagnosing clonorchiasis when the biliary tract is obstructed or when there is a light infection. We evaluated the infection states of CS in patients with biliary tract diseases using a bile sample. From January 2001 to August 2003, 238 patients who had undergone endoscopic biliary drainage were prospectively included in the study. The patients' bile samples were obtained directly from the nasobiliary drainage tube and then analyzed to detect CS eggs. The overall CS egg positive rate was 28.2% (35.4% in males, 19.4% in females). The egg positive rate was similar in all age groups examined: 26.7% in 30-39 years, 25.0% in 40-49 years, 24.4% in 50-59 years, 30.2% in 60-69 years, 35.3% in 70-79 years, and 25.0% in 80 years of age and over. There were no significant differences in the egg positive rate between the disease groups: 32.6% in bile duct cancer, 38.5% in gallbladder cancer, and 26.4% in gallstone diseases. Our results show that the CS infection rate was very high, regardless of the age, gender, and type of diseases of the patients. Although the study population was limited to patients with biliary tract diseases, it is assumed that clonorchiasis is still an endemic disease in Ulsan, Korea.

In 1932, Loffler described a syndrome of self-limiting, transient pulmonary infiltrates associated with peripheral blood eosinophilia and mild pulmonary symptoms. A number of conditions are related to pulmonary eosinophilia or pulmonary infiltration with eosinophilia. Especially, parasitic infestations are often related to pulmonary eosinophilia, but only two cases associated with Clonorchis sinensis have been anecdotally reported in English literature. Here we report a case of migrating pulmonary eosniophilic infiltrations associated with Clonorchis sinensis that was successfully treated with praziquantel. Clonorchiasis should be considered in patients with marked eosinophilia and pulmonary infiltrations.

Acalculous cholecystitis is an inflammation of the gallbladder in the absence of gallstones. Diagnosing this condition is often difficult because of the patient's debilitated medical condition and because of the limitation of biliary imaging technique. Nonetheless, its recognition and therapy are critically important, for if left untreated, many patients will die. During 10 years and 6 months from January 1986 to June 1996, 52 patients underwent assessment and treatment for acalculous cholecystitis at the Department of Surgery, Kyungpook National University Hospital. A clinical analysis of those patients was done and the following results were obtained: The incidence rate was 3.5%. The most prevalent age group was the seventh decade (13cases), and the male-to-female ratio was 1.4 : 1. Possible etiologic factors were found in 25 cases (48.1%). These factors were surgery in 5 cases (9.6%), trauma in 5 cases (9.6%), sepsis in 5 cases (9.6%), clonorchiasis in 5 cases (9.6%), and others in 5 cases(9.6%). Neither Ascariasis nor Salmonellosis was found as a predisposing factor in this study.The main cardinal symptoms and physical signs were similar to those of calculous cholecystitis. The sensitivities of diagnostic imaging by ultrasonography and computed tomography were 88.4% and 100%, respectively. Of the 52 patients, 46 cases underwent cholecystectomy, and 6 cases were initially treated by percutaneous transhepatic cholecystostomy. Of these 6 cases, two patients had cholecystostomies during subsequent abdominal operations for other conditions. Two patients had the cholecystostomy tube removed 2 months after an uneventful recovery and have had no further biliary problems. The other two patients died. The operative findings were cholecystitis only in 26 cases (56.5%), cholecystitis with localized peritonitis in 18 cases (39.1%), and cholecystitis with generalized peritonitis in 2 cases (4.3%). Postoperative complications occurred in 16 cases (34.8%), and wound infection was the most common complication (62.5% of all complications).The overall mortality was 9.6%. Conclusively, acalculous cholecystitis had high morbidity and mortality in this study. Once the diagnosis of acalculous cholecystitis is made, the gallbladder should be drained or removed. A decision as to the best approach depends on the specific situation and will require close cooperation between the internist, the surgeon, and the radiologist.

6.Liver Flukes: the Malady Neglected.
Korean Journal of Radiology 2011;12(3):269-279
Liver fluke disease is a chronic parasitic inflammatory disease of the bile ducts. Infection occurs through ingestion of fluke-infested, fresh-water raw fish. The most well-known species that cause human infection are Clonorchis sinensis, Opisthorchis viverrini and Opisthorchis felineus. Adult flukes settle in the small intrahepatic bile ducts and then they live there for 20-30 years. The long-lived flukes cause long-lasting chronic inflammation of the bile ducts and this produces epithelial hyperplasia, periductal fibrosis and bile duct dilatation. The vast majority of patients are asymptomatic, but the patients with heavy infection suffer from lassitude and nonspecific abdominal complaints. The complications are stone formation, recurrent pyogenic cholangitis and cholangiocarcinoma. Approximately 35 million people are infected with liver flukes throughout the world and the exceptionally high incidence of cholangiocarcinoma in some endemic areas is closely related with a high prevalence of liver fluke infection. Considering the impact of this food-borne malady on public health and the severe possible clinical consequences, liver fluke infection should not be forgotten or neglected.

We measured changes in sonographic findings of patients with clonorchiasis after a treatment in a highly endemic area. A total of 347 residents showed positive stool results for Clonorchis sinensis eggs in a village in northeastern China, and were treated with praziquantel. Of them, 132 patients underwent abdominal sonography both before and 1 year after treatment, and the changes in sonographic findings of 83 cured subjects were compared. Diffuse dilatation of intrahepatic bile ducts (DDIHD) was found in 82 patients (98.2%) before and 80 (96.4%) after treatment, which was improved in 3, aggravated in 1, and unchanged in 79 patients. Increased periductal echogenicity (IPDE) was observed in 42 patients (50.6%) before and 45 (54.2%) after treatment, which was improved in 5, aggravated in 8, and unchanged in 70 patients. Floating echogenic foci in the gallbladder (FEFGB) was detected in 32 patients (38.6%) before and 17 (20.5%) after treatment, which was improved in 20, aggravated in 5, and unchanged in 58 patients. Improvement of FEFGB only was statistically significantly (P = 0.004). The present results confirm that DDIHD and IPDE persist but FEFGB decreases significantly at 1 year after treatment. In a heavy endemic area, the sonographic finding of FEFGB may suggest active clonorchiasis 1 year after treatment.

This study examined the association of cytokine gene polymorphisms with intrahepatic bile duct wall fibrosis in human clonorchiasis. A total of 240 residents in Heilongjiang, China underwent ultrasonography, blood sampling, and stool examination. Single nucleotide polymorphism (SNP) sites for IFN-gamma (+874 T/A), IL-10 (-1,082 G/A, -819 C/T, -592 C/A), TNF-alpha (-308 G/A), and TGF-beta1 (codon 10 T/C, codon 25 G/C) genes were observed with the TaqMan allelic discrimination assay. No significant correlation was observed between individual cytokine gene polymorphisms and intrahepatic duct dilatation (IHDD). Among individuals with clonorchiasis of moderate intensity, the incidence of IHDD was high in those with IFN-gamma intermediate-producing genotype, +874AT (80.0%, P = 0.177), and in those with TNF-alpha low-producing genotype, -308GG (63.0%, P = 0.148). According to the combination of IFN-gamma and TNF-alpha genotypes, the risks for IHDD could be stratified into high (intermediate-producing IFN-gamma and low producing TNF-alpha), moderate, and low (low-producing IFN-gamma and high producing TNF-alpha) risk groups. The incidence of IHDD was significantly different among these groups (P = 0.022): 88.9% (odds ratio, OR = 24.0) in high, 56.5% (OR = 3.9) in moderate, and 25.0% (OR = 1) in low risk groups. SNP of IFN-gamma and TNF-alpha genes may contribute to the modulation of fibrosis in the intrahepatic bile duct wall in clonorchiasis patients.

The main causes of biliary obstruction are stones and cancers. Fascioliasis is a very rare case which causes biliary obstruction. Fascioliasis is a zoonosis caused by Fasciola hepatica which infects herbivores like sheep and cattle. F. hepatica lives in the biliary system or the liver parenchyma of a host. In Korea, the occurrence of this infection in human is very rare and only few cases have been reported. A 32-year-old male presented with upper abdominal pain and jaundice. His laboratory finding revealed elevated liver transaminases. Abdomen CT scan showed mild left intrahepatic bile duct dilatation. On ERCP, adult F. hepatica worms were found and were thus removed. Concurrently, clonorchiasis was diagnosed by stool exam and serologic enzyme-linked immunosorbent assay test. Clonorchiasis was treated with praziquantel. Herein, we report a case of intrahepatic bile duct dilatation due to F. hepatica infection with concurrent Clonorchis sinensis infestation.

The Korean Journal of Parasitology 2011;49(3):273-275
Praziquantel is the drug of choice for clonorchiasis. Since clonorchiasis is endemic in most river basins, praziquantel has been widely used for 30 years in Korea. A 54-year-old Korean woman suffered from hypersensitive reactions, such as nausea, dyspnea, rash, and urticaria after taking the first dose of praziquantel to treat clonorchiasis. She ingested one dose again and the same symptoms appeared, and she was treated at a clinic with anti-histamines. She tried one more dose with anti-histamines but found the same symptoms. Later, she was found to pass eggs of Clonorchis sinensis and medicated with flubendazole. The hypersensitive reaction to praziquantel is rare but occurs. This is the 5th case report in the world.
