Gallbladder injuries are rare in cases of blunt abdominal trauma and are usually associated with damage to other internal organs. If the physician does not suspect gallbladder injury and check imaging studies carefully, it may be difficult to distinguish a gallbladder injury from gallbladder stone, hematoma, or bleeding. Therefore, in order not to miss the diagnosis, the clinical findings and correlation should be confirmed. In the present case, a 60-year-old male presented to a local trauma center complaining of pain in the upper right quadrant and chest wall following a motor vehicle collision. Abdominal computed tomography (CT) showed a hepatic laceration and hematoma in the parenchyma in segments 4, 5, and 6 and active bleeding in the lumen of the gallbladder. Traumatic gallbladder injuries generally require surgery, but in this case, non-operative management was possible with cautious follow-up consisting of abdominal CT and angiography with repeated physical examinations and hemodynamic monitoring in the intensive care unit.

급증하는 간세포암 환자에게 간동맥 화학 색전술은 효과적인 중재적 시술 방법 중 하나이다. 이때 PET/CT 검사는 색전 후 잔존 암세포의 존재 및 전이여부와 예후를 판단하는데 중요한 역할을 한다. 한편 간동맥 화학 색전술에 사용되는 색전물질인 Lipiodol은 PET/CT 검사에서 인공물을 생성하고 정량평가에 영향을 준다. 이에 본 연구는 Lipiodol이 영상에 미치는 영향의 정도를 방사능 값과 백분율 오차로 평가하고자 하였다. 1994 NEMA Phantom에 Lipiodol과 Teflon, 물을 세 개의 삽입물에 넣고 나머지 부분을 배후 방사능 $20{\pm}10MBq$를 주입하고 충분히 섞은 후 2분 30초/bed data를 획득 하였다. 재구성 방법은 반복 영상 재구성법으로 반복횟수 2회, 부분 집합 수 20을 적용하였으며, Lipiodol과 Teflon, 물, 인공물 발생부위, 배후 방사능에 관심영역을 설정하고 방사능 값과 백분율 오차를 산출 하여 비교하였다. 방사능 값은 Teflon, 물, Lipiodol, 삽입물 사이 인공물 발생 부위, 배후 방사능 부위에서 각 영역 중 방사능 값은 $0.09{\pm}0.04$, $0.40{\pm}0.17$, $1.55{\pm}0.75$, $2.5{\pm}1.09$, $2.65{\pm}1.16 kBq/ml$(P<0.05)으로 통계적으로 유의한 차이를 보였다. 백분율 오차가 Lipiodol에서 물에 비해 118%, 배후 방사능에 비해서 52%, Teflon에 비해 180%의 차이가 있었다. Lipiodol을 주입한 후 검사에서 감약 보정의 영향을 받아 오차로 인한 방사능 농도 값이 다른 삽입물에 비해 현저히 높고 배후 방사능보다는 작다는 것을 알 수 있었다. 따라서 Lipiodol과 같은 조영 물질을 사용한 검사에서는 인공물에 대한 영향을 고려해야 하며 임상에서는 감약 보정을 적용하지 않은 영상을 참고해서 검사가 이루어 질 수 있도록 해야 한다.

An iodized oil such as Ethiodol or Lipiodol was selectively retained in the tumor vessels of the large hepatomas as well as in the small daughter hepatomas for long periods following the intra-arterial hepatic injection of such contrast material. The specific aim of the study is to deliver a high internal radiation dose to hepatocellular carcinoma (HCC) in an attempt to control the disease. We were able to replace a small fraction of the stable iodine (I-127) of the 37% iodine in Lipiodol by the $I^{-131}$ with 100% exchange efficiency. $I^{-131}$ labeled Lipiodol was injected through the super-selected tumor feeding artery under superselection or into the proper hepatic arterial level of patients who have malignant hepatomas confirmed by aspiration cytology serum AFP and various imaging modalities. Clinical traial was performed on 43 cases during recent 6 months and follow-up observation was carried out. No severe complications or other adverse reactions were encountered until nowdays. $I^{-131}-Lipiodol$ was stable in vivo and no significant activity was noted in the thyroid, stomach, blood and urine after the injection. Only small fraction of radioisotope activity was noticed in the both side of lungs. Tumor to normal liver radio was very high. Therefore, $I^{-131}-Lipiodol$ (or P-32-Lipiodol) will be effective delivering high internal radiation dose to the tumor while delivering small radiation doses to normal tissues. Labeling, tumor dose calculation and preliminary findings will be presented.

Eighty-four cases of mitral commissurotomy were done in this department between October 1958 and September 1970. Therc wcre 54 males and 30 females. Six cases were under the age of 20 years. Prcoperativc embolization occurred in 9. 5% of the cases. consisting of 8. 3% cerebral and 1.2% peripheral embolization. Intraoperative and postoperative cmbolization occurred in 4.7% of the cases, with 1. 2% cerebral and 3.5% peripheral embolism. Two out of three postopeative embolism cases expired, one of which was caused by septic cerebral embolism due to valve vegetation nnd the other by mesenteric embolism. Atrial fibrillation was 1loted ill 43% of the case. Seventy closed mitral commissurotomy was done by left appendegeal approach with finger fracture method or Bailey's guillotine valvotome. Fourteen open mitral commissurotomy cases were done either by right side approach or median sternotomy, three of which were reoperation cases after blind mitral commissurotomy. One out of 14 cases were operated on with open mitral commissurotomy and concomitant open aortic valve bicuspidalization, This case expired due to severe serum hepatitis ten days after operation. Thirty-two per cent of valve calcification was noted during operation and one of which had marked vegetation on the valve cusps too. Operative mortality was 1.4% in blind mitral commissurotomy and 14% in open mitral commissurotomy. Over-all mortality in the entire series was 3.5%. One case among the blind commissurotomy cases expired during operation due to left inferior pulmonary vein laceration and death was caused in two open mitral commissurotomy cases by coronary artery airembolism. Three hospital death occurred in blind operation group, one due to coronary embolism, and two by hepatic failures. Three hospital death among open heart surgery cases were caused by hepatic failure in two and cerebral embolism in one cases. ln most of the survivors improved functional capacity and exercise lolerance were noted.

Purpose: To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment. Materials and Methods: In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the cystic duct and common hepatic duct as the dividing point. Locoregional failure sites were categorized as follows: the hepatoduodenal ligament and tumor bed, the celiac artery and superior mesenteric artery, and other sites. Results: The median follow-up time was 29 months for surviving patients. Three-year locoregional progression-free survival, progression-free survival, and overall survival rates were 50%, 42%, and 52%, respectively. Regarding initial failures, 79% and 81% were locoregional failures in proximal and distal EBDC patients, respectively. The most common site was the hepatoduodenal ligament and tumor bed. In the multivariate analysis, perineural invasion was associated with poor locoregional progression-free survival (p = 0.023) and progression-free survival (p = 0.012); and elevated postoperative CA19-9 (${\geq}37U/mL$) did with poor locoregional progression-free survival (p = 0.002), progression-free survival (p < 0.001) and overall survival (p < 0.001). Conclusion: Both proximal and distal EBDC showed remarkable proportion of locoregional failure. Perineural invasion and elevated postoperative CA19-9 were risk factors of locoregional failure. In these patients with high risk of locoregional failure, adjuvant radiotherapy could be considered to improve locoregional control.

It is now generally accepted that individuals at increased risk for cardiovascular disease may be identified by certain traits or habbits. The factors such as high blood pressure, elevated blood cholestrol, age, sex and obesity are associated with increseaed frequency of disease. The blood cholesterol level lowering will decrease cardiovascular disease risk. The regression of atherosclerosis can be achieved by lowering the level of circulating cholesterol. Those things are connected with the quantity and quality of protein, fats, carbohydrates, especially soluble and non-soluble fiber, magnesium and calcium. The lipoprotein and lipid metabolism are connected with the lipid transport. The factors on lipid absorption and blood serum lipid pattern of human are exist. The factors have a variety of materials with different chemical and physical properties. The soluble fiber diet make a low blood and liver lipids. Many kind of soluble fiber results in a lowering of blood cholesterol and triglyceride levels. The cholesterol lowering effects of dietery fiber may be a results of alterations of in intestinal handling of fats, hepatic metabolism of fatty acid or triglyceride acid metabolism of lipoprotein. It is investigated that the high density lipoprotein (HDL) is inversely related to coronary artery disease. It has been postulated that HDL may be an important factor in cholesterol efflux from the tissues, therby reducing the amount of cholesterol deposited there. Alternatively, the HDL may pick up cholestyl ester and phospholipid during normal VLDL lipolysis in the plasma. The HDL levels are relatively insensitive to diet. At present time, the cause-and -diet effect of HDL's inverse relation to CHD remains unclear.

A 51-year-old male patient had four times of massive hematochezia episode three days before arrival. Carbohydrate antigen (CA) 19-9 level was extremely elevated. Computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography identified 5.7 cm sized periampullary duodenal cancer with regional metastatic lymph nodes and vascular invasion to aberrant right hepatic artery, main portal vein, and superior mesenteric vein. Diagnosed as duodenal adenocarcinoma through endoscopic biopsy, 16 times of FOLFIRI (5-fluorouracil, leucovorin, irinotecan) was conducted. The regimen changed to XELOX (capecitabine, oxaliplatine), four times of administration was done, and the CA19-9 level dramatically decreased. The tumor decreased to 2.1 cm. After R0 laparoscopic pylorus preserving pancreatoduodenectomy, no adjuvant therapy was given. No sign of recurrence or metastasis was reported, and the patient reached complete remission after five years. We reported a case where neoadjuvant chemotherapy for locally advanced duodenal adenocarcinoma was shown to be effective.

$^{99m}Tc$-macroaggregated albumin (MAA) 를 이용한 간동맥 관류스캔(hepatic arterial perfusion scintigraphy, HAPS)은 간종양의 경동맥 화학요법을 위해 종양의 관류 등을 평가하는데 매우 유용한 방법으로 알려져 있다. 본 연구는 간암환자(hepatocellular carcinoma, HCC)에서의 정상 간 조직에 대한 간세포암의 상대적인 혈류량을 평가하여 종양의 형태, 크기와 lung shunting, tumor to normal ratio (T/N ratio)를 측정하여 HAPS 의 유용성을 알아보고자 하였다. 2009년 6월부터 2009년 9월까지 본원에서 HCC 진단을 받은 환자 7명(평균 64세, 남자 6명, 여자 1명)을 대상으로 하였다. $^{99m}Tc$-MAA 5 mCi를 간 동맥 내에 위치된 카테타를 통하여 주입하고 20분경과 후 HAPS를 시행하였다. 환자의 흉부와 복부가 포함되게 시야를 잡고 anterior, posterior, both lateral 상을 얻고 SPECT를 시행하였다. liver, tumor, lung의 ROI를 그리고 각각의 count와 count/pixel (mean value) 를 구하여 lung shunting, T/N ratio를 구하였다. anterior, posterior 상에서 얻어진 ROI에서 얻어진 tumor size는 2.0~10.8 cm(평균 3.75 cm), liver size 는 8.8~18.5 cm(평균14.6 cm)였다. total tumor와 total normal의 mean value를 통해 얻은 T/N ratio의 범위는 2.41~5.76(평균 3.8)였다. total lung과 total liver의 counts를 통해 얻은 lung shunting의 범위는 3.14~13.92%(평균 6.77%)였다. $^{99m}Tc$-MAA를 이용한 HAPS 는 정상 간 조직에 비해 간세포암내에 강한 방사능 섭취를 보였으며 종양의 크기, 위치 및 T/N ratio를 통한 정량적 관류 평가를 할 수 있었다. 또한 폐 섭취 빈도는 종양 내 동정맥 단락을 추정할 수 있어 간동맥 동위원소 치료 전 단락 유무를 평가할 수 있다는 점이 유용하게 활용될 수 있을 것이다. 따라서 $^{99m}Tc$-MAA를 이용한 HAPS는 간암의 평가 및 치료를 결정 할 수 있는 유용한 검사법으로 이용될 수 있을 것으로 사료된다.
