This experiment was conducted to investigate the performance of Korean native bulls fed rice straw and forages or rice straw only as a roughage sources during the growing period of 180 days. The results obtained are summarized as follows: In the body gain, animals fed rice straw and forages and those fed rice straw only had 182.6㎏ and 157.2 ㎏, respectively. Thus, animals fed rice straw and forages are greater than those fed rice straw only. Feed efficiencies are 7.66 for animals fed rice straw and forages and 8.12 for those fed rice straw only. Animals fed rice straw and forages as a roughage sources were better than those fed rice straw only. There are significant differences in the body gain and feed efficiency between treatments (P$lt;0.01). Feed intake was much greater for animals fed rice straw and forages than those fed rice straw only. It can be concluded that forage would increase palatability and obserbed that good roughages are closely related to the feed intake. In the change of body type, the height of hip cross and fore shank circumference were significantly (P$lt;0.01) longer for animals fed rice straw only than those of animals fed rice straw and forages. Rump length was longer for animals fed rice straw and forages than those animals fed rice straw only and there was significant difference between treatments (P$lt;0.05). However, withers height, body length, heart girth, chest width, girth of chest and abdomen, chest width and pin bone width were not statistically significant between treatments.

안동원,심주현,윤정환,김청용,이효석,김영태,김윤준 대한간학회 2011 Clinical and Molecular Hepatology(대한간학회지) Vol.17 No.2

Background/Aims: Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the appropriate treatment for needle-track seeding and its clinical outcome. Methods:We analyzed the clinical characteristics and treatment outcomes in eight patients who experienced needle-track seeding from HCC after an US-guided procedure (FNAB, PEI, or PTBD) between January 1990 and July 2004. Results:Seven (0.14%) of 5,092 patients who experienced needle-track seeding (2 after PEI, 4 after FNAB, and 1 after PTBD) during the study period and 1 other patient who experienced needle-track seeding recently were recruited for this study. Two of the eight patients underwent mass excision and the other six patients underwent en-bloc wide excision for the needle-track seeding. Tumors recurred in the needle- tracks in both patients who underwent mass excision but not in the six patients who underwent en-bloc wide excision. Mortality occurred in three patients who experienced the recurrence and progression of intrahepatic HCC. Conclusions:The incidence of needle-track seeding after US-guided procedures in HCC was 0.14%. En-bloc wide excision seems to be the optimal treatment for minimizing the probability of tumor recurrence due to needle-track seeding.

원발성 경화성 담관염과 원발성 담즙성 담관염의 최신 지견

Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are immune-mediated chronic liver diseases. PSC is a rare disorder characterized by multi-focal bile duct strictures and progressive liver diseases that ultimately results in the need for liver transplantation in most patients. Imaging studies, such as MRCP, have an essential role in the diagnosis of most cases of PSC. PSC is usually accompanied by inflammatory bowel disease, and there is a high risk of cholangiocarcinoma and colorectal cancer in PSC. No medical therapies have been proven to delay the progression of PSC. Endoscopic intervention for tissue diagnosis or biliary drainage is frequently required in cases of PSC with a dominant stricture, acute cholangitis, or clinically suspected cholangiocarcinoma. PBC is a chronic inflammatory autoimmune cholestatic liver disease, which, when untreated, will culminate in end-stage biliary cirrhosis requiring liver transplantation. A diagnosis is usually based on the presence of serum liver tests indicative of cholestatic hepatitis in association with circulating antimitochondrial antibodies. Patient presentation and course can be diverse in PBC, and risk stratification is important for ensuring that all patients receive a personalized approach to their care. Medical therapy using ursodeoxycholic acid or obeticholic acid has an important role in reducing the progression to end-stage liver disease in PBC.

한국의 내시경적 역행성 담췌관 조영술에 대한 전국적인 실태 조사

안동원,한정호,김홍자,김형근,손병관,이선영,박주상,이엄석,김현수,조광범,김호각,박선미 대한췌담도학회 2019 대한췌담도학회지 Vol.24 No.1

배경/목적: 한국의 내시경적 역행성 담췌관 조영술(ERCP)의 질을 평가한 전국적인 실태 조사 결과를 표준 질지표와 비교하여 기술하고자 한다. 방법: 건강보험심사평가원의 자료를 분석하였고, 이후에 무기명으로 전국적인 설문 조사를 시행하였다. 결과: ERCP 의사 157명 중에서 129명이 설문에 응답하여 82.2%의 회수율을 보였다. 한국에서 ERCP 시행률은 지속적으로 증가하였다. 약 반수의 의사는 1인당 ERCP 양이 연간 200예 이상으로 시술량이 많은 ERCP 의사에 속하였다. 대부분의 ERCP 의사들은 1단계의 ERCP 시술을 시행하였으나 담췌관 내압 측정, 담관-췌관경 및 췌장 시술은 많은 양의 시술을 하는 병원에서만 시행하였다. 대부분의 ERCP 의사들은 90% 이상의 성공률을 보였으나, 예비 괄약근 절개율이 약 25%로 표준 질지표보다 높았다. 12명의 ERCP 의사들이 최근 1년간 ERCP 후 환자가 사망하는 합병증을 경험하였다. 또한 ERCP 수련과 시술량이 낮거나 중등도인 병원의 방사선 차폐는 표준 질지표에 도달하지 못하였다. 결론: 한국의 ERCP 술기는 표준적인 질지표를 충족하였으나, ERCP 수련과 방사선 차폐 문제는 향후 개선이 필요하다. Background/Aims: The aim of this study is to describe the outcome of the national survey and to determine the endoscopic retrograde cholangiopancreatography (ERCP) quality in Korea by comparing with the quality indicators. Methods: We used the database of Health Insurance Review & Assessment Service and then performed anonymous national survey. Results: Completed questionnaires were returned by 129 of 157 ERCP endoscopists. In Korea, annual ERCP rates have been consistently increased over years. Individual ERCP volume was high (>200 per year) in about half of ERCP endoscopists. Most ERCP endoscopists performed all of level I procedures. However, manometry, cholangiopancreatoscopy, and pancreatic procedures were performed mostly in institutions with high hospital volume. The rate of overall success was more than 90% in most ERCP endoscopists. However, the rate of precut sphincterotomy was high in more than a fourth of ERCP endoscopists. Twelve ERCP endoscopists experienced post-ERCP mortality within recent 1 year. ERCP training and radiation protection during ERCP did not meet the standard of quality indicators especially in institutions with low or moderate hospital volume. Conclusions: Technical issues during ERCP procedures in Korea fulfill the standard of quality indicators. However, a great effort is needed to improve issues about ERCP training and radiation protection.

Pancreatic tuberculosis is a rare clinical entity. Because of the diverse clinical and radiological pictures of pancreatic tuberculosis, the accurate diagnosis of this chronic infection and the differentiation from other pancreatic diseases such as malignancy is challenging at clinical practice. We here report a case of pancreatic tuberculosis mimicking pancreatic cyst lesions. Pancreatic tuberculosis should be considered as one of differential diagnosis if pancreatic solid or cystic lesions exist in tuberculosis endemic areas, especially in case with the fluctuating changes of pancreatic lesions on serial imaging studies.

담석증은 비교적 유병률이 높은 질환으로 담석의 증상 및 합병증으로는 무증상에서부터 담도통, 급성 담낭염, 담석 췌장염, 급성 담관염, 담석 장폐쇄, 담낭-위장관 누공 등 다양하다. 그 중 담낭 내 출혈과 이로 인한 위장관 출혈로 발현되는 담석증은 전세계적으로 매우 드물게 보고되고 있다. 저자들은 대량의 혈변 배설을 주소로 내원한 63세 여자에서 담석으로 인한 담낭 내 출혈과 담낭과 횡행결장 간의 유착으로 인한 하부 위장관 출혈로 진단한 증례를 경험하였기에 보고하는 바이다. Cholelithiasis is a relatively common disease and can present with various clinical manifestations and complications such as no symptoms, biliary pain, acute cholecystitis, biliary pancreatitis, acute cholangitis, gallstone ileus and biliary enteric fistula. However, cholelithiasis presenting with intra-gallbladder bleeding and massive gastrointestinal bleeding are relatively rare in the worldwide literature and there have been only a few reported case studies. We present here an interesting case of a 63 year-old women with gallstone, active intra-gallbladder bleeding and massive hematochezia who underwent open cholecystectomy, resection and anastomosis of the transverse colon. This patient's pathologic evaluation revealed a finding of acute and chronic cholecystitis with marked hemorrhage and transmural fibrinoid necrosis in the transverse colon.
