The distribution of the bile and hepatic ducts within the liver of 24 Korean native cattle were observed. Vinylite solution was injected into common bile ducts on 13 cases for cast preparation. The angiography was prepared in 11 cases which were injected 30% barium sulfate solution into the common bile ducts and then radiographed on X-ray apparatus. The results were summarized as follows; 1. The dorsal, intermediate and ventral ducts of left hepatic lobes, ducts of quadrate lobes, and ducts of papillary process were collected into left hepatic ducts. The dorsal and ventral ducts of right hepatic lobe, ducts of caudate process and papillary process were collected into right hepatic ducts. 2. The bile ducts in the left hepatic lobes were collected into dorsal, ventral and intermediate ducts of left hepatic lobes. The intermediate ducts of left hepatic lobes was absent in some cases(5 cases, 20.83%). 3. In some cases, the ventral ducts of right hepatic lobes were collected into right hepatic ducts directly. 4. The ducts of quadate lobes were collected into left hepatic ducts(8 cases, 33.33%), ventral ducts of left hepatic lobes(13 cases, 54.17%), and dorsal duct of left hepatic lobes, intermediate and ventral ducts of left hepatic lobe, common trunk collected into intermediate and ventral duct of left hepatic lobe and left hepatic duct(1 cases, 4.17%) respectively. 5. The ducts of papillary process were collected into left and right hepatic ducts(12 cases, 50%), left hepatic ducts only(11 cases, 45.83%) or right hepatic duct only(1 cases, 4.17%). 6. The average length of right hepatic ducts was 26.87(6-45.8)mm. The average length of left hepatic ducts was 56.68(6-127)mm. The length of gallbladder was 128.60(104-160)mm on the average. The breadth of gallbladder was 67.16(38.4-153.4)mm on the average. But there was a difference in the length and the breadth according to the quantity of bile. 7. The ramified angles of dorsal, intermediate and ventral ducts of left hepatic lobes, ducts of quadrate lobes, ducts of papillary processes and caudate processes, dorsal and ventral ducts of right hepatic lobes and cystic ducts were 130-170, 160-200, 190-250, 240-300, 90-140, 320-350, 30-100, 270-330 and 240-300 degrees respectively.

Obstruction of the extrahepatic bile ducts is the most common cause of conjugated hyperbilirubinemia in early infancy. More than 90% of such obstructive lesions are accounted for by extrahepatic biliary atresia. A rare lesion is obstruction of the common duct by impacted, thickened secretions and bile. Bile plug syndrome is defined as extrahepatic obstruction of the bile ducts by bile sludge in term infants without anatomic abnormalities, congenital chemical defects of bile, or hepatocellular lesions. Obstruction of extrahepatic ducts by plugs of biliary material apperas to be due to the inspissation and precipitation of bile and mucus within the lumen of the ducts. Cholestasis and precipitation of bile develop in association with abnormal composition of bile in cystic fibrosis, hepatocellular damage, prolonged erythroblastic jaundice, altered biliary dynamics with total parenteral nutrition, gut dysfunction, diuretic therapy, exchange transfusions and perinatal hemolysis. In those cases, the term inspissated bile syndrome is used. The clinical and laboratory findings in bile plug syndrome are identical to those observed in biliary atresia and choledochal cyst. The diagnosis can be suspected based on the findings of clinical and laboratory examinations together with hepatobiliary imaging, ultrasonography, radionuclide scan and liver biopsy. We experienced a case of spontaneous resolution of bile plug syndrome in a 4-year-old girl. We report this case with brief review related literatures.

목 적: 지금까지의 경복부 초음파를 이용한 간외담관에 대한 검사는 주로 담낭과 간외 담도, 즉 총수담관(CBD)만을 확인하는 수준의 검사가 전부인 것처럼 여겨져 왔다. 그러나 저자들은 임상에서의 다양한 경험을 바탕으로 간외담도의 비정상 확장에 대해 분석할 수 있고, 담도질환 유무 및 관련성을 평가하는데 필요한 기술적 접근 방법에 대한 새로운 이론적 토대를 마련하였다. 이 새로운 이론을 기본으로 신뢰성 있는 검사 성적을 얻기 위하여 일정기간 교육 후 scanning 훈련을 시켜 그 효과를 평가함으로서 담관질환 검사의 새로운 기준을 정립코자 한다. 대상 및 방법: 초음파 교육생 30명을 대상으로 간외담관에 대한 새로운 이론에 근거하여 기술적 접근 방법에 대한 교육을 전수한 후 학생 1인당 3시간(30분${\times}$6회)을 배당하여 scanning 훈련을 집중였다. 교육 방법은 강사와 학생 1:1 방식으로 하였다. Scanning 훈련 후 평가 기준으로 모든 학생에게 5분 내에 간외담관 중에서 좌우 담관으로부터 (1) 담낭관 합류부(간외담관 및 담낭관), (2) 췌장 상부담관, (3) 췌두부내 담관, (4) 유두부내 공통관 등 네 분절을 명확하게 구분된 개념으로 scan하게 한 후 정확도를 평가하였다. 결 과: 기존의 교육과 훈련 방식은 간외담관에 대한 경복부 초음파검사의 신뢰도가 매우 낮고, 췌장 상부 담관에만 국한적으로 영상화할 수 있었다. 그러나 새로운 이론에 근거한 교육과 훈련을 마친 후 성적의 평가는 모든 학생(30명)이 (1) 담낭관 합류부(간외담관 및 담낭관), (2) 췌장 상부담관까지 객관성 있게 접근하였다. 24명의 학생이 (3) 췌두부내 담관 말단까지 접근하였으며, 1명의 학생만이 (4) 유두부내 공통관까지 영상화할 수 있었다. 결 론: 간내외 담관의 평가는 간내인성, 담관성 그리고 병태생리학적 다면 평가가 이뤄져야 하지만, 경복부초음파검사에 의해 간외담관을 유두부내 공통관까지 객관적이고 신뢰성 있게 영상화시킬 수 있다면 단순 감별진단 목적으로 시행하는 ERCP같은 환자에게 고통이 수반된 침습적인 검사를 대폭 줄일 수 있을 것이다. 따라서 저자들이 제시한 새로운 검사방법으로 간외 담관에 대한 기술적 접근 방법을 scanning 훈련하여 임상에 적용하게 된다면 초음파의 객관적인 신뢰도를 높일 수 있을 것으로 생각된다.

Among several diagnostic tools for clonorchiasis (Clonorchis sinensis infection), radiologic examinations are commonly used in clinical practices. During the 2 past decades, many reports regarding imaging findings of clonorchiasis were introduced. The basic imaging finding of clonorchiasis is diffuse dilatation of the peripheral intra-hepatic bile ducts, without dilation of the large intrahepatic or extrahepatic bile ducts. By this finding, however, active clonorchiasis cannot be differentiated from cured infection. Some recent radiologic studies suggested specific findings of active clonorchiasis. Besides direct demonstration of worms, increased periductal echogenicity on sonography and periductal enhancement on dynamic contrast-enhanced CT or MR imaging possibly represent active clonorchiasis. Those images of the liver clonorchiasis are known to be correlated with worm burdens (EPG counts) in their frequency and also severity. The images of cholangiocarcinoma associated with clonorchiasis show both the tumor with obstruction images and diffuse dilatation of the peripheral intrahepatic bile ducts. Radiological images can be a good practical alternative diagnostic method of clonorchiasis.

We describe the imaging features of two cases of biliary ascariasis. Ultrasonography and CT showed no specific abnormal findings, but MR cholangiography clearly demonstrated an intraductal linear filling defect that led to the correct diagnosis. MR cholangiography is thus a useful technique for the diagnosis of biliary ascariasis.

간흡충에 감염된 담관은 확장되면서 상피세포의 수가 크게 증식하여 점막층이 두꺼워지고 과식증에 의해 점막의 단면이 유두상으로 관찰된다. Bromodeoxyuridine (BrdU)이 세포가 핵산을 복제할 때에 끼어 들어가는 성질을 이용하여, 이 연구에서는 담관 상피세포 중에서 합성기(Sphase)에 있는 세포의 분율을 파악하고자 하였다. 흰쥐에 간흡충의 피낭유충을 100 개씩 경구 감염시키고, 15주까지 간의 각 엽에 있는 담관의 조직절편을 만들어서 다세포군항체와 ABC complex를 이용한 염색을 실시하였다. 그 결과 충제가 들어 있는 담관에서는 감염 1주에 상피 세포의 2.9-10.2%가 염색에 양성이었고, 2주에 7.3-12.8%가, 5주에는 7.3-13.4%가, 15주에 8.4-14.8%가 BrdU를 함유하였다. 대조군 흰쥐나 실험군 동물의 감염되지 않은 담관의 경우에는 0-2.7%가 염색에 양성으로 나타났다. 염색된 상피세포는 주로 점막 상피세포층의 기저부에서 관찰되었다. 이 결과에 의하면 간흡충과 직접 접촉하는 담관의 상피세포가 뚜렷하게 증식하고 있어 충체의 어떠한 물리적인 또는 화학적인 자극이 있더라도 가까운 부위에서 주로 작용하고 있다고 판단하였다.

This study was done to find the method of the extermination of Fasciola hepatica matacercariae. And the artificial infection was carried out with 30 metacercarae exposed to 5% ammonia water and not-exposed to 5% ammonia water. Serial determinations of live weight, red blood cell, hemoglobin, packed cell volume, and eosinophils were performed in rats at 7 days interval for 16 weeks after infection (WAI). Recovery of worm burden and microscopic findings of livr was performed in rats at 10 WAI. The results in this work were summarized as follows; 1. Fasciola spp metacercariae exposed to 5% ammonia water have lost their ability of infection. 2. In teh exposed group, the mean of worm recovered was 2.25 and the common bile duct was swelling up to 0.71cm in diameter. 3. The value of live weight was different in two groups as the not-exposed group and the exposed group were 321.28, 384.38 at 10 WAI, respectively. 4. In the not-exposed group, at 7 WAI, hemoglobin at 5 WAI and packed cell volume at 7 WAI wre minimally decreased to $5.84{\times}10^{-6}/mm^3$, 11.53g/dl and 43.2%, respectively. But those three values were slowly increased at 10 WAI. Rercent cosinophil was increased to 12.2% at 4 WAI and slightly decreased to 7.9% at 10 WAI. But there are no stastistical singnificance between the exposed group and the normal control group. 5. In histolgical findings in the not-exposed group, the dilated common bile ducts and intrahepatic bile ducts showed distinct hyperplasia of the epithelium. Lymphocytes and eosinophils were infilterated around the bile ducts. The hepatic cells and Kupffer cells showed swollen appearance.

Biliary atresia (BA) is an infantile cholestatic disease of progressive obliterative cholangiopathy with varying degrees of damage to both extra and intrahepatic bile ducts due to unknown causes. The diagnostic studies should be done to diagnose or exclude BA without unnecessary delay. Kasai portoenterostomy is the first choice of treatment for bile drainage from microscopic bile ductules present in the portal fibrous mass. The medical management after Kasai portoenterostomy should be done carefully to maintain bile excretion and prevent and treat complications Including cholangitis, hepatic fibrosis, portal hypertension and nutritional problem. The reported five years-survival rates after Kasai portoenterostomy range from 30 to 60 %. About 20 % of all patients undergoing Kasai portoenterostomy during infancy survive into adulthood with their native liver. Even if Kasai portoenterostomy remains as the first line of treatment In BA, liver transplantation serves as a good salvage treatment when portoenterostomy fails or liver function gradually deteriorates after initially successful establishment of bile flow, Overall 5-year survival rate in BA is about 90 % in recent series.
