Hepatitis A virus (HAV) is invariably a self-limited infection, with the majority of patients recovering completely. Underlying chronic liver disease and old age are associated with increased severity and an increased risk of fulminant hepatic failure. We report a case of fulminant hepatic failure caused by HAV superinfection in a 36-year-old male hepatitis B carrier. Recently, the incidence of acute hepatitis A in Korean adults has been increasing. Furthermore, Korea is an endemic area for chronic liver disease, including hepatitis B and C. Therefore, the risk of progression to acute fulminant hepatic failure should be considered for hepatitis A patients with impaired liver function, especially with underlying chronic liver disease.

Pancreatic tuberculosis is a rare clinical entity, presenting as malignancy mimicking pancreatic mass. Therefore, it represents a diagnostic challenge. To date, ten cases have been reported in Korea. I report an additional case and review all Korean reports about pancreatic tuberculosis. A 57-year-old woman presented with abdominal pain. Abdominal computed tomography (CT) revealed a 2.2×1.2 cm cystic mass in pancreatic body. She was followed for nine months, at which time a cystic mass was enlarged to 3.3×2.2 cm in size on the CT. An exploratory laparotomy was performed for the accurate diagnosis and to rule out the possibility of malignant change. Pathological examination of the resected specimen revealed chronic granulomatous inflammation with caseous necrosis and multinucleated giant cells, which was compatible with tuberculosis. Among the 11 cases of pancreatic tuberculosis, five cases were combined with pulmonary tuberculosis. The pancreatic tuberculosis frequently presented with multicystic pancreatic mass (81%) and the most common anatomic locations were the head (73%), tail (18%), and body (9%). Three cases were diagnosed by using US or EUS guided fine needle aspiration biopsy (FNAB), and all cases were medically cured without exploratory laparotomy. In summary, pancreatic tuberculosis, despite its rarity, should be considered for differential diagnosis of pancreatic cystic mass in endemic countries. Clinical suspicion and accurate diagnostic approach including FNAB of pancreatic tuberculosis are needed to avoid performing unnecessary laparotomy. (Korean J Gastroenterol 2009;53:324-328)

목적: 직장 유암종은 대장내시경 확대로 발견이 증가하고 있으며 일차로 내시경 절제를 고려해야 한다. 하지만 진단 내시경 시 조직검사로 인한 병변 변형에 의해 내시경 절제에 어려움을 겪는 경우가 있다. 따라서 조직검사 후 변형이 직장 유암종의 내시경 절제에 미치는 영향을 분석하여 치료에 도움이 되고자 하였다. 대상 및 방법: 2000년부터 2007년까지 직장 유암종으로 내시경 절제술을 시행한 42예를 조사하여 진단 시 조직검사 유무에 따라 조직검사군 22예와 조직검사 미시행군 20예로 분류하였다. 조직검사군과 미시행군 간 유암종 크기, 위치 등 임상 차이는 없었다. 각 군 간 점막하 주입 시 융기 제한, 내시경 제거 방법 차이 및 분할 절제 유무 등을 조사하였다. 결과: 내시경 절제술 시 점막하 주입에 따른 점막 융기 제한을 보인 경우가 조직검사군에서 17예(77%)로 미시행군 9예(45%)에 비해 많았다(p=0.03). 점막 융기 제한에 영향을 미치는 내시경 소견은 조직검사로 인한 종괴의 함몰된 반흔이 관찰된 경우, 조직검사를 한 5 mm 이하의 유암종, 조직검사 후 활동 궤양이 있는 경우였다. 내시경 절제 시 올가미를 이용한 절제술, cap을 이용한 흡인절제술, 고무밴드 결찰 후 절제술에서는 두 군 간 차이가 없으나 내시경점막하박리술을 이용한 경우는 조직검사군 5예로 미시행군 1예에 비해 많았다. 분할절제된 경우는 조직검사군 5예(23%)로 미시행군 2예(10%)에 비해 많았으나 유의한 차이는 없었다. 결론: 직장 유암종에서 조직검사로 인한 변형은 내시경 절제 시 점막 융기를 저해하는 요인이 될 수 있다. 따라서 내시경 절제 이전 조직검사는 최소한으로 해야 한다. Background/Aims: While endoscopic resection could be considered as the best choice for the treatment of small rectal carcinoid, the colonoscopic biopsies performed at the time of detection may lead to scar and ulcer formation and cause unpredicted difficulty in the endoscopic resection. This study was evaluated to analyze the relationship between the post-biopsy scar and the limitation of submucosal elevation for the endoscopic resection of rectal carcinoids. Methods: Twenty two cases of rectal carcinoid which received prior biopsies before the endoscopic resection were retrospectively compared with 20 non-biopsied cases. All two groups were treated by endoscopic resection from January 2000 to December 2007. There was no difference in the clinical characteristics and endoscopic findings such as size and location between the two groups. Results: The limited submucosal elevation was experienced in 17 cases (77%) in the biopsy group, significantly more frequent than 9 cases (45%) in the non-biopsy group (p=0.03). The colonoscopic findings which contribute to difficult submucosal elevation were the depressive scar formation after biopsy, the size less than 5 mm in the biopsy group, active ulcer formation after biopsy. Regarding the resection method, endoscopic submucosal dissection was frequently adopted (23% vs. 5%) in the biopsy group. The frequency of endoscopic piecemeal resection in biopsy group was higher than non-biopsy group (23% vs 10%), and all cases were subsequently resected by other endoscopic methods. Conculsions: The post-biopsy scar can interfere with successful submucosal elevation for endoscopic resection of rectal carcinoids. The number of forcep biopsy should be minimized in the diagnostic colonoscopy when endoscopic resection is planned rectal carcinoids. (Korean J Gastroenterol 2009;53:36-42)

간세포암종 감시 검사: 위험도 평가

조성범 ( Sung Bum Cho ) 대한간학회 2019 Postgraduate Courses (PG) Vol.2019 No.1

The purpose of surveillance of hepatocellular carcinoma (HCC) is improved survival with higher chances to offer a curative treatment after diagnosing earlier. The methods of surveillance are feasible, cost-effective and useful clinically in the target risk population. As suggested by cost-effectiveness analyses, an incidence of 1.5% per year or greater would warrant HCC surveillance by ultrasound with or without alpha fetoprotein with current guidelines. The need for individualized methods or intervals of surveillance has recently emerged based on different personal HCC risk. In considering to maximize effectiveness of HCC surveillance, earlier diagnosis of HCC is important at very early HCC stage (BCLC 0, below 2 cm single tumor) with possible to radiofrequency ablation. Individualized methods of HCC surveillance are recently challenged according to risk stratification of HCC.

This study was conducted to investigate the prevalence rate for rabies antibody (PRRA) of dogs near the Pukhansan National Park and in some other districts in Seoul Metropolitan city. From April to July 2000, a total of 414 serum samples were taken from dogs for breeding (92), pet dogs (62), and unclaimed/stray dogs (62). Rabies virus antibodies were detected by neutralizing peroxidase-linked assay (NPLA). Of 414 sera tested, 145 (35%) were positive to rabies virus antibody. PRRA in Pukhansan National Park area and in the other districts of Seoul city were 34.8% and 35.4%, respectively. There was no significant difference in the prevalence rate between these two districts. PRRA in pet dogs, unclaimed/stray dogs, and dogs for breeding were 39.5%, 35%, and 27.2% respectively. PRRA in dogs from residential areas, apartments, animal hospitals, and farms were 32.5%, 60%, 35.3%, and 26.7% respectively. Especially, the dogs reared in apartments had a significantly higher seroprevalence (60%) than those in residential or farm areas. PRRA in less than 1 year, 1~<2 years, 2~<3 years, and over 3 years old dogs were 14.7%, 40.4%, 38.4%, and 53% respectively, and overall 35% in the dog population. In addition, we found that dogs less than 1 year of age had lower antibody prevalence than those over 1 year of age. It was concluded that enhancement of vaccination is important in the prevention of the rabies, and that rabies vaccines should not be less supplied than the population of the dog.

We report a case of small cell carcinoma of extrahepatic bile duct presenting with jaundice and hemobilia. A 59-year-old woman was admitted due to right upper quadrant pain and jaundice. An abdominal computed tomography revealed a 2 cm sized mass in the extrahepatic bile duct. Endoscopic retrograde cholangiopancreatography revealed bloody discharge coming out of the papillary orifice in endoscopic view and a dilated extrahepatic bile duct with multiple irregular filling defects in cholangiogram. A coronal T2-weighted image revealed a hyper-intense mass at extrahepatic bile duct. Laparotomy was performed, and pathologic examination of resected specimen showed tumor cells having round to oval nuclei with coarsely granular chromatin and scanty cytoplasm, which were immunoreactive for synaptophysin and chromogranin A, compatible with the diagnosis of small cell carcinoma. The small cell carcinoma of bile duct, despite its rarity, should be considered in differential diagnosis of the causes for obstructive jaundice and hemobilia.

간세포암종 치료는 암종의 다양성과 동반된 간경변 상태에 따라 적절한 치료에도 일관된 경과를보이지 않는 경우가 많아 다 양한 임상 요소를 고려한 다학제 접근을 통한 치료방법이 추천되고 있다. 최근 간세포암종 치료는 기존 치료법의 진보와 더불 어 새로운 표적치료제와 면역치료제가 도입되면서 패러다임의 변화가 시작되고 있으며 이를 반영하여 2018년도 유럽간학회 에서는modified BCLC 병기와 함께 간세포암종 치료 가이드라인이 새롭게 업데이트 되었다. 이번 발표를 통하여 다양한 치 료법과 특성을 소개하여 간세포암 치료를 시작하려는 임상의 및 연구자에게 도움이 되고자 하였다.
