Purpose : To evaluate the usefulness of MRCP in the diagnosis of the variable causes of common bile duct(CBD) dilatation, except stone or tumor Materials and methods : Twenty-six patients(M:F=15:11, mean age; 62 years) with both MRCP and ERCP were included in this study. Dynamic MRCP(n=12) and contrast-enhanced MRI(n=10) of abdomen were also added. Dilatation of CBD, intrahepatic ducts and pancreatic duct was evaluated, including coexistence of intrahepatic ductal stone, pancreatic pseudocyst, and papillary or papillary edema. The criteria of CBD dilatation was over than 7mm(n= 21, without cholecystectomy) or 10 mm(n=5, with cholecystecto-my) in diameter on T2-weighted coronal image. Results : The mean diameter of CBD was 12.7mm without cholecystectomy(9-19 mm) and 13.0 mm with cholecystectomy(10-15mm), respectively(p 〉0.05). Cholangitis(n=11, 42.3%), chronic pancreatitis(n=8, 30.8%), stenosis of distal CBD(n= 6, 23.1%), periampullary diverticulum(n=3, 11.5%), stenosis of ampulla of Vater(n=2, 7.7%), dysfunction of sphincter of Oddi(n=2, 7.7%), acute focal pancreatitis in the pancreatic head(n=2, 7.7%), papillitis(n=1, 3.8%), pseudocyst in the pancre atic head(n = 1, 3.8%), and ascaris in CBD(n=1, 3.8%) were noted. Pancreatic duct dilatation(n=10, 38.5%) and duodenal diverticulum(n=3, 11.5%) were also seen on MRC P. On dynamic MRCP(12 patients), distal CBD was visualized in 2 patients(16.7%), which was not shown on routine MRCP. Only 1 patient(10.0%) showed papillitis with slightly enhancing papilla on contrast-enhanced MRI (10 patients). Conclusion : MRCP was thought to be helpful in the evaluation of the causes of CBD dilatation, not caused by stone or tumor, especially in the cases of stenosis of distal CBD and chronic pancreatitis, dysfunction of sphincter of Oddi on dynamic MRCP and cholangitis and pericholangitic abnormality on contrast-enhanced MRI.

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.

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.

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.

54 patients who had symptoms after biliary operation were studied by $^{99m}Tc-DISIDA$ hepatobiliary scintigraphy for evaluation of clinical utility, with regional emphasis of recurrent pyogenic cholangitis (RPC) and intrahepatic stones. As expected, the most common disease was recurrent pyogenic cholangitis regardless of surgical anastomosis, 58% and next frequent disease was clonorhis sinensis infestation, 26%, stenosis of ampula vater 8%, and chronic hepatitis 4% (20% of patients had hepatitis but they showed clinically and scintigraphically dominallt combined disease feature). 87% of recurrent pyogenic cholangitis was associated with stones in intra or/and extrahepatic ducts and only 11.4% of RPC was found to be associated with Cs-infestation. The scintigraphic diagnosis of RPC was 81.6% and 78.6% of stones was detected by indirect visualization of scintigraphy findings and 71.7% of Cs-infestation was detected by scintigraphy. The characteristic bile flow pattern were described.

Purpose: Parenteral nutrition (PN) is known to provide therapeutic beneficial improvements in malnourished patients for whom enteral nutrition is not feasible. The objective of this study was to investigate the current clinical characteristics and utilization of PN in Korea. Methods: We analyzed the Health Insurance Review Agency National Inpatients Sample database from 2014 to 2016, which included 13% of all hospitalized patients in Korea. Adult patients aged 20 years or older and receiving premixed multi-chamber bag containing PN were included for this study. Patient characteristics, admission type, primary diagnosis, and hospital demographics were evaluated. SAS version 9.4 was used for data analysis. Results: From 2014 to 2016, 149,504 patients received premixed PN, with 226,281 PN prescriptions being written. The mean patient age was 65.0 years, and 81,876 patients (54.8%) were male. Premixed 3-chamber bag and 2-chamber bag PN solutions were utilized in 131,808 (88.2%) and 32,033 (21.4%) patients, respectively. The number of patients hospitalized through the emergency department were 70,693 (47.3%), whereas 43,125 patients (28.8%) were administered PN in intensive care units. In the adult PN patients, the highest primary diagnosis was malignant neoplasm of the stomach (8,911, 6.0%), followed by organism unspecified pneumonia (7,008, 4.7%), and gastroenteritis and colitis of unspecified origin (6,381, 4.3%). Overall, 34% of adult PN patients were diagnosed with malignancies, the most common being neoplasm of the stomach (17.7%), neoplasm of bronchus/lung (11.2%), neoplasm of colon (11.1%), and neoplasm of liver/intrahepatic bile ducts (10.0%). PN solutions were most frequently administered in the metropolitan area (55.0%) and in hospitals with more than 1,000 beds (23.6%). Conclusion: PN was commonly administered in older patients, with primary diagnosis of malignancy in a significant number of cases. This study is the first large-scale description of PN-prescribing patterns in real-world clinical practice in South Korea.

Purpose: Biliary atresia, one of the major causes of neonatal cholestais, is an idiopathic, serious disorder, affecting the newborn that results in complete obstruction of biliary tract. Successful reestablishment of bile flow is dependent on early surgical intervention, early diagnosis is imperative. The authors evaluate the utility of Tc-99m-labeled diisoprpyliminodiacetic acid (DISIDA) hepatobiliary scintigraphy in the diagnosis of biliary atresia. Methods: From January, 1995 to August, 1999, total 60 patients with neonatal cholestasis underwent Tc-99m DISIDA hepatobiliary scintigraphy at Asan Medical Center. Results: The undelying causes of neonatal cholestasis were biliary atresia in 14, neonatal hepatitis in 33, intrahepatic bile duct paucity in 9, and total parenteral nutrition induced cholestasis in 4. All patient with biliary atresia were interpreted correctely in DISIDA hepatobiliary scintigraphy, showing 100% sensitivity. Of the 46 patients with neonatal hepatitis and other causes, 37 patients had intestinal radioactivity showing 80% specificity. Conclusion: Visualization of DISIDA in the intestinal tract indicates patency of the biliary ducts and excludes the diagnosis of biliary atresia. But the absence of intestinal excretion on the DISIDA hepatobiliary scintigraphy dose not necessarily indicate biliary atresia.

Caroli's disease is a fibrocystic liver disease. Autosomal recessive disorder is characterized by congenital multiple dilatation of the bile duct. Computerized tomography, magnetic resonance imaging, cholangiography and ultrasound are among the methods for diagnosing caroli disease. Computerized tomography is essential for detecting and distinguishing fibroplastic liver disease and is useful for determining intrahepatic bile duct dilatation. However, awareness of the possible side effects of using contrast mediums is necessary. A typical method of magnetic resonance cholangiography is used for magnetic resonance imaging. A non-invasive examination can reduce the pain of the patient, and the anatomical structure of the bile pancreatic duct and the presence or absence of lesions can be easily and quickly observed. Biliary contrast is an effective diagnostic method that can directly visualize various cystic dilatations throughout the enlarged bile duct. However, since this procedure is also an invasive procedure, it is recommended not for diagnosis but for treatment purposes. Ultrasonography can confirm similar findings to computerized tomography. The hepatic artery root is difficult to prove with conventional grayscale ultrasound. However, it is of clinical value in that it can not only describe dilated bile ducts with vascular roots in the tube but also easily identify color Doppler signals in the tube. With the development of video diagnostics, early diagnosis has become possible through computerized tomography, magnetic resonance imaging, cholangiography, and ultrasound. In order to further contribute to the development of video diagnostics so that long-term prognosis can be improved after treatment through early diagnosis, we examined what aspects of each test's caroli disease appear.

Because a cavitary pulmonary metastasis is rare, it may not be readily identified. However, various types of cancers can metastasize to the lung in the form of cavities. We report a case of a multiple cavitary metastases to the lung from a cholangiocarcinoma in a 60-year-old man. He complained of generalized weakness and a poor oral intake for 2 months. The plain chest radiography and the chest computed tomography showed multiple small thick-walled cavities and nodules the both lungs. A bronchoscopic examination revealed a focal irregularly elevated surface of the mucosa at the orifice of the superior segment of the right lower lobe and the biopsy demonstrated an infiltrative metastatic adenocarcinoma. The abdomen-pelvis computed tomography showed an ill-marginated and irregularly low-dense area in the right lobe of the liver and a diffuse dilatation of the peripheral intrahepatic bile ducts. The esophagogastroscopy and colonoscopy showed no abnormal findings. It was concluded that the cholangiocarcinoma of the liver metastasized to the lung in the form of cavities. Thereafter, the patient underwent six cycles of the systemic chemotherapy with gemcitabine and cisplatin, and the follow-up imaging studies showed a partial response.
