Down syndrome is a rare cause of neonatal cholestasis. Neonatal cholestasis in a patient with Down syndrome is usually associated with severe liver diseases, such as neonatal hemochromatosis, myeloproliferative disorder and intrahepatic bile duct paucity. We experienced a case of idiopathic neonatal cholestasis in a patient with Down syndrome, which resolved spontaneously.

Clonorchis sinensis is the most common fish-borne intestinal parasite in Korea. The aim of the present investigation was to survey the status of C. sinensis infection and analyze associated risk factors in residents of Haman-gun, Gyeongsangnam-do. A total of 5,114 residents from 10 administrative towns/villages voluntarily agreed to participate in the study, which comprised fecal examination, a questionnaire survey for risk factors, ultrasonography, and enzyme-linked immunosorbent assay for cancer biomarker detection in the blood. We detected C. sinensis eggs in 5.3% of the subjects. By region, Gunbuk-myeon had the highest number of residents with C. sinensis eggs. The infection rate and intensity were higher in male than in female residents. Based on the risk factor questionnaire, infection was highly associated with drinking, a history of C. sinensis infection, and the practice of eating of raw freshwater fish. Extension of the bile duct, infection intensity, and cancer biomarker detection significantly correlated with the presence of eggs in the study population. In conclusion, the development of feasible, long-term control policies and strategies for the elimination of C. sinensis in Korea is still required.

In the present communication, the results will be reported on a clinical study of how well scintigraphic visualization of the hepatobiliary elements and several commonly used clinical liver function tests correlate each other in various diseases oft hepatobiliary system. The demonstrability of the biliary tract, gallbladder (GB) and duodenum was rather closely paralleled to serum bilirubin level and less closely to alkaline phosphatase and rather poorly to SGOT and SGPT. The biliary tree could not be visualized scintigraphically when bilirubin exceeded 10.5mg/dl. The usefulness of Tc-99m EHIDA [N-(2,6-diethylacetanilido) iminodiacetic acid, made by Amersham, England] hepatobiliary scintigraphy (Tc EHIDA HBS) in settling diagnostic controversy and ambiguity raised by oral cholecystography, intravenous cholangiography and ultrasonography in many hepatobiliary diseases is well known. The purpose of this investigation was to semiquantitatively evaluate the scintigraphic demonstrability of the hepatobiliary tract, GB and duodenum following intravenous injection of Tc-99m EHIDA in normal subjects and in patients with a disturbed liver function from various hepatobiliary diseases. The hepatobiliary scintigraphy was performed in 10 normal subjects and 39 patients with various hepatobiliary diseases (Table 1) at the Dept. of Radiology, St. Mary's Hospital Catholic Medical College, Seoul, Korea during 2 years period from September 1979. Scintigraphic examination was started at end of 3 minutes after intravenous injection of Tc-99m EHIDA in the amount of $50{\mu}Ci/kg$ and was continued until after 30 minutes at 5 minutes interval. The imaging was usually terminated when the tracer could be seen in the duodenum. Late scintigrams were obatained at 1 1/2, 3, 4 and 6 hours when reeded. Scintigrams were analyzed in terms of promptness and clarity of visualization of the biliary tree, GB and duodenum and demonstrability of these anatomical landmarks was correlated with the values of liver function tests. The demonstrability of the common hepatic duct, common bile duct, GB and duodenum was closely paralleled to the level of serum bilirubin when it is less than 10.5 mg/dl as shown in figure 1. However when the bilirubin exceeded 10.5 mg/dl the time of visualization between protracted reaching a flat curve or plateau around 10.5 mg/dl. The biliary tract could not be visualized when the bilirubin was higher than 10.5 mg/dl. The correlability between scintigraphic demonstration and serum alkaline phosphatase was less strong and between scintigraphic demonstration and SGOT and SGPT was rather poor. The present clinical study confirmed the usefulness and limitation of Tc-99m EHIDA hepatobiliary scintigraphy in visulizing and diagnosing the biliary system and duodenum when radiogrpahy and ultrasonography failed to provide useful informations. Scintigraphy was very helpful in the diagnosis of neonatal hepatitis, biliary atresia, cholecystitis and extrahepatic biliary obstruction. The hepatobiliary system and duodenum were visualized when serum bilirubin level was less than 10.5 mg/dl, SGOT 135 units, SGPT 114 units and alkaline phosphatase 52.2 KAU.

Backgrounds/Aims: Data regarding outcomes of endoscopic retrograde cholangiography (ERC) in liver transplant (LT) recipients with biliary-enteric (BE) anastomosis are limited. We report outcomes of ERC and percutaneous transhepatic biliary drainage (PTBD) as first-line therapies in LT recipients with BE anastomosis. Methods: All LT recipients with Roux-BE anastomosis from 2001 to 2020 were divided into ERC and PTBD subgroups. Technical success was defined as the ability to cannulate the bile duct. Clinical success was defined as the ability to perform cholangiography and therapeutic interventions. Results: A total of 36 LT recipients (25 males, age 53.5 ± 13 years) with Roux-BE anastomosis who underwent biliary intervention were identified. The most common indications for a BE anastomosis were primary sclerosing cholangitis (n = 14) and duct size mismatch (n = 10). Among the 29 patients who initially underwent ERC, technical success and clinical success were achieved in 24 (82.8%) and 22 (75.9%) patients, respectively. The initial endoscope used for the ERC was a single balloon enteroscope in 16 patients, a double balloon enteroscope in 7 patients, a pediatric colonoscope in 5 patients, and a conventional reusable duodenoscope in 1 patient. Among the 7 patients who underwent PTBD as the initial therapy, six (85.7%) achieved technical and clinical success (p = 0.57). Conclusions: In LT patients with Roux-BE anastomosis requiring biliary intervention, ERC with a balloon-assisted enteroscope is safe with a success rate comparable to PTBD. Both ERC and PTBD can be considered as first-line therapies for LT recipients with a BE anastomosis.

Methods: Patients who underwent cholecystectomy were classified into two groups according to their GBWT status (GBWT+ vs. GBWT-). Results: Among 1,211 patients who underwent cholecystectomy, GBWT+ was seen in 177 (14.6%). The GBWT+ group was significantly older with more males, higher ASA score, higher alkaline phosphatase level, higher international normalized ratio, and lower albumin level than the GBWT- group. On ultrasound, GBWT+ patients had larger stone size, more pericholecystic fluid, more common bile duct stone, and more biliary pancreatitis. Compared with the GBWT- group, the GBWT+ group had more urgent surgeries (12.4% vs. 3.2%, p = 0.001), higher conversion rate (4.5% vs. 0.3%, p = 0.001), prolonged operative time (67 ± 38 vs. 54 ± 29 min; p = 0.001), more bleeding (3.4% vs. 0.5%, p = 0.002), and more need of drain (21.5% vs. 10.5%, p = 0.001). By multivariate analysis, factors associated with increased length of hospital stay were GBWT+ (HR: 1.97, 95% CI: 1.19-3.25, p = 0.008), urgent surgery (HR: 10.2, 95% CI: 4.07-25.92, p = 0.001), prolonged surgery (HR: 1.01, 95% CI: 1.0-1.02, p = 0.001), and postoperative drain (HR: 11.3, 95% CI: 6.40-20.0, p = 0.001). Conclusions: Variables such as GBWT ≥ 5 mm, urgent prolonged operation, and postoperative drains are independent predictors of extended hospital stay. GBWT+ patients are twice likely to stay in hospital for more than 72 hours and more prone to develop complications than GBWT- patients.

Bronchobiliary fistula (BBF), defined as an abnormal communication between the biliary duct and bronchial trees, is a very rare condition. Bilioptysis is a pathognomonic finding for BBF. We studied a 58-year-old man, who had a BBF complicated by liver biloma that occurred after radiofrequency ablation. The diagnosis was confirmed by the presence of bile-stained sputum and an Endoscopic Retrograde Cholangio-Pancreatography. BBF was treated successfully by endoscopic sphincterotomy and biliary drainage with insertion of a double pig-tail plastic stent into the biloma. We suggest that the optimal choice of treatment modality for BBF depends on the natural course of the underlying disease, and the status of the biliary stricture.

Clonorchis sinensis is a Group-I bio-carcinogen, associated with cholangiocarcinoma (CCA). The hamster is the only experimental model of C. sinensis-mediated CCA, but we oblige another animal model. The present study intended to develop a C. sinensis (Cs) mediated CCA model using C3H/He mice, co-stimulated with N-nitrosodimethylamine (NDMA) and dicyclanil (DC). The mice were divided into 8 groups with different combinations of Cs, NDMA, and DC. Six months later the mice were sacrificed and subjected to gross and histopathological examination. The body weights were significantly reduced among the groups treated with 2 or more agents (eg. Cs+NDMA, Cs+DC, NDMA+DC, and Cs+NDMA+DC). In contrast, liver weight percentages to body weight were increased in above groups by 4.1% to 4.7%. A Change of the spleen weight was observed only in Cs+NDMA group. Though C. sinensis infection is evident from hyperplastic changes, only 1 worm was recovered. Two mice, 1 from Cs and the other from Cs+DC group, showed mass forming lesions; 1 ($281.2mm^3$) from the Cs group was a hepatocellular adenoma and the other ($280.6mm^3$) from the Cs+DC group was a cystic mass (peliosis). Higher prevalence of gray-white nodules was observed in Cs group (42.9%) followed by Cs+NDMA+DC group (21.4%). The mice of the Cs+NDMA+DC group showed hyper-proliferation of the bile duct with fibrotic changes. No characteristic change for CCA was recognized in any of the groups. In conclusion, C3H/He mice produce no CCA but extensive fibrosis when they are challenged by Cs, NDMA, and DC together.
