A case of Fasciola gigantica-induced biliary obstruction and cholestasis is reported in Turkey. The patient was a 37-year-old woman, and suffered from icterus, ascites, and pain in her right upper abdominal region. A total of 7 living adult flukes were recovered during endoscopic retrograde cholangiopancreatography (ERCP). A single dose of triclabendazole was administered to treat possible remaining worms. She was living in a village of southeast of Anatolia region and had sheeps and cows. She had the history of eating lettuce, mallow, dill, and parsley without washing. This is the first case of fascioliasis which was treated via endoscopic biliary extraction during ERCP in Turkey.

Biliary tract cancer (BTC) is a rare cancer and is associated with a poor prognosis. To understand the genetic characteristics of BTC, we analyzed whole-exome sequencing data and identified somatic mutations in patients with BTC. Tumors and matched blood or normal samples were obtained from seven patients with cholangiocarcinoma who underwent surgical resection. We discovered inactivating mutations of tumor suppressor genes, including APC, TP53, and ARID1A, in three patients. Activating mutations of KRAS and NRAS were also identified. Our analyses identified somatic mutations in Korean patients with BTC.

A 64-year-old man was admitted due to jaundice for 2 weeks. Radiologic findings revealed biliary stricture at the hepatic hilum with intrahepatic duct dilation suggesting Bismuth type IV Klatskin tumor. Jaundice improved spontaneously several days after hospitalization. Surgical treatment was considered but he only wanted to observe without specific treatment. Ten months later, he was re-admitted due to the recurrence of jaundice. Computed tomography (CT) showed no significant difference compared to previous results. Serum cancer antigen 19-9 and Immunoglobulin G4 were normal. Endoscopic forcep biopsy during endoscopic retrograde cholagiopancreatography (ERCP) revealed chronic inflammation. After steroid use under possible diagnosis of IgG4 related cholangiopathy, biliary stricture improved slightly. Four years later, he was hospitalized with the occurrence of acute cholangitis. Endoscopic retrograde biliary drainage was performed following endobiliary forcep biopsy. Pathology revealed well-differentiated adenocarcinoma at this time. Combined chemotherapy based on gemcitabine and cisplatin was performed. Six months later, CT revealed partial response.

Choledochal cyst is a condition involving an abnormal dilation of the bile ducts, which can lead to various symptoms and comorbidities, including cancer. The treatment of choice for choledochal cyst is surgical correction including choledochal cyst excision and Roux-en-y hepaticoenterostomy. Minimal invasive methods like laparoscopic methods or robotic methods are used for surgical correction of choledochal cysts; however, it is still controversial which method is superior. A Korean company, LIVESMED, developed Artisential^®, a laparoscopic surgical instrument that can overcome the drawbacks of laparoscopic methods. This article presents a case of the first Artisential^®-performed surgical excision of a choledochal cyst and hepaticojejunostomy.

That different mechanisms are involved in the secretory processes by the liver and the kidney of various dyes has been indicated by Sporter (1959), Kim and Hong (1963). Andrews (1958). suggested that a striking difference in the dye-secretory mechanism existed even in the same organ from species to species. Hence, the attempt has been made to study in the rabbit the secretory processes by the live. and the kidney of either phenol red (PSP), bromsulfalein (BSP) or green in the presence of Na-acetate, Na-taurocholate, P-Aminohippurate (PAH) or Benemid. In 37 rabbits, weighing about 2kg., anesthetized with ether, a dye was administered in such 8 manner that the plasma concentration was kept at a relatively constant level throughout the whole experimental period. Hepatic bile sad urine samples were quantitatively collected through the canulae which were previously inserted into the common bile duct (with the cystic duct ligated) and the urinary bladder, respectively, while arterial samples were taken from a femoral artery. After 50 min from the onset of dye administration, these samples were obtained every 10 mit for a period of 40 min. This was followed by the administration of either Na-acetate, Na-tauro-cholate, PAH or Benemid with a repetition of the same sample collecting procedures just stated. The results may be summarized as follows: 1) Na·acetate augmented urinary clearance of PSP by nearly 300 per cent, but lowered urinary BSP clearance by about 50 per cent. It enhanced biliary BSP clearance by 40% and had no effect on biliary psp clearance. 2) Na-taurocholate lowered biliary and urinary clearance of PSP by 10 per cent and 30 per cent respectively, and had no effect on both biliary and urinary clearance of BSP. 3) PAH lowered both biliary and urinary excretion of BSP and PSP, while it lowered the biliary excretion of indocyanine green which was excreted only in the bile. 4) Benemid suppressed BSP excretion by the liver and the kidney. 5) raper chromatographic analysis of PSP and of BSP in the bile and urine samples gave the following results: a) PSP Ivas excreted in the urine and bile only in free forms, and no modification in the excretory pattern was brought about by Na-taurocholate. b) BSP was excreted in the urine in 4 different conjugated froms and in the bile in both 3 different conjugated forms and in a free form. Na-taurocholate modified the excretory pattern of the urinary BSP.

목 적: 담즙정체를 보이는 환자의 간조직에서 cDNA microarray를 이용한 유전자 발현 분석을 통 하여 담도 폐쇄증의 발생과정에 관여하는 유전자를 규명하고자 연구를 시행하였다. 방 법: 환자의 간조직은 담즙정체를 보이는 11명의 환자로부터 진단적 간생검시 얻은 간조직의 일부를 이용하였다. 이들의 원인 질환은 담도 폐쇄증이 7명, 신생아 간염 증후군이 4명이었다. 정상대조군의 간조직은 생체부분 간이식시 성인 공여자로부터 얻은 간조직의 일부를 이용하였다. 간조직에서 분리된 mRNA를 4.7K 인간유전자 cDNA microarray를 이용하여 유전자 발현의 양상을 분석하였다. 결 과: 분석한 4,700종의 유전자 중 담즙정체 환자 11명 모두의 간조직에서 발현이 증가된 유전자는 17종이 발견되었고, 발현이 감소된 유전자는 20종이 발견되었다. 담도 폐쇄증 환자와 신생아 간염 증후군 환자 사이에 49종의 유전자에서 발현의 차이가 관찰되었고, 특히 담도 폐쇄증에서는 발현이 증가하였으나 신생아 간염 증후군에서는 발현이 감소된 유전자는 24종이었으며 이들 유전자 발현의 차이에 의해서 두 군간의 감별이 가능하였다. 결 론: 신생아 간질환에서 담도 폐쇄증 환자들은 모두 일정한 양상을 보여주어 이에 대한 분석을 통하여 담도 폐쇄증의 조기 감별 진단을 할 수 있을것을 시사하였다. 또한 담도 폐쇄증에서 특이 발현을 보이는 유전자의 추가적인 기능 연구를 시행함으로써 담도 폐쇄증의 원인을 규명하는데 도움을 줄 수 있을 것으로 생각한다.

배경/목적: 담도암에서 플라스틱 스텐트 너비에 따른 스텐트 생존 차이에 대한 데이터는 부족하다. 이번 연구의 목적은 담도암에서 7-프렌치와 10-프렌치 플라스틱 스텐트의 생존 차이를 보고 어떤 인자가 개방성에 영향을 미치는지 확인하고자 한다. 방법: 2010년 1월부터 2014년 10월까지 연세대학교 원주세브란스기독병원에서 담도암으로 담도가 막힌 환자들을 등록하였다. 결과: 총 215명(7-프렌치:10-프렌치 = 89명:126명)의 환자를 후향적으로 등록하였다. 암의 위치는 총담관(111명), 간문부 담관(45명), 바터팽대부(59명)였다. 스텐트 이동이나 폐쇄는 두 군 간에 통계적 차이가 없었다. 중앙 스텐트 생존은 7-프렌치의 경우 3.3개월이었고 10-프렌치의 경우 5.9개월이었다(p = 0.543). 플라스틱 스텐트 너비는 스텐트 생존에 영향을 미치지 않았다(Hazard Ratio: 1.11, 95% CI 0.71-1.73, p = 0.649). 결론: 담도암 치료에 있어 7-프렌치와 10-프렌치 플라스틱 스텐트는 스텐트 이동이나 폐쇄 차이가 없었고 스텐트 생존에 있어 7-프렌치 플라스틱 스텐트가 10-프렌치에 비해 열등하지 않았다.

The present study examined the effects of butylated hydroxyanisole (BHA) on acetaminophen (AA)-induced hepatotoxicity in male rats and also examined the effects of these compounds on the biliary excretion of phenolphthalein (PP) and the hepatic glucuronidation. Male Sprague-Da-wley rats were pretreated with BHA (0.75% in diet for 10 days) were given single dose of AA (600mg/kg, ip) and liver function was determined 24 hr later. Serum activity of alanine aminotransferase (ALT) and histopathology were used as indices of hepatotoxicity.
