    Portal hypertension as a consequence of liver cirrhosis is responsible for serious complications such as variceal bleeding, ascites and hepatic encephalopathy. Successful pharmacological treatment of portal hypertension can prevent the risk of the variceal bleeding, and contribute to reduce the morbidity and mortality in patients with liver cirrhosis. To identify the effect of drugs on portal hypertension, portal pressure was evaluated accurately before and after the drug administration. The hepatic venous pressure gradient has been accepted as the gold-standard method for assessing the severity of portal hypertension and the response to drug treatment. The mean hepatic venous pressure gradient was 15.1+/-5.4 mmHg in Korean cirrhotic patients who had experienced variceal bleeding. Non-selective beta blockers are the treatment of choice for primary and secondary prevention of variceal bleeding. The dose of propranolol should be subsequently adjusted until the resting heart rate had been reduced by 25% or less than 55 beats per minute. It has been reported that the optimal dose of propranolol is variable due to racial differences in cardiovascular receptor sensitivity. In Korean patients with portal hypertension and liver cirrhosis, the mean required dose of propranolol to reach target heart rate was 165 mg (range; 80-280 mg). This review covers mainly the results of the pharmacological therapy of portal hypertension in Korean cirrhotic patients.

    BACKGROUND/AIMS: Mesenchymal tumors are the most frequent submucosal tumors in gastrointestinal trail. We reviewed the mesenchymal tumors which are confirmed by pathology to examine whether the invasive approach of all mesenchymal tumors is necessary. METHODS: This study was performed on fifty-nine patients who has mesenchymal tumors confirmed by endoscopic or surgical resection from January 2000 to June 2004. RESULTS: Mesenchymal tumors consisted of thirty-six gastrointestinal stromal tumors (GISTs), 20 leiomyomas and 3 schwannomas. All the esophageal tumors were leiomyoma (12/12, 100%). In stomach, there were 32 GISTs (76.2%), 7 leiomyomas (16.7%) and 3 schwannomas (7.1%). And there were 4 GISTs (80.0%) and 1 leiomyoma (20.0%) in duodenum. Tumors less than 1 cm in maximal diameter were leiomyoma or GISTs with very low risk of aggressive behavior. 56.1% of the tumors larger than 1 cm consisted of low, intermediate or high risk GISTs. CONCLUSIONS: Biopsy must be considered according to its size and anatomic location of mesenchymal tumors. The invasive approach for every esophageal submucosal tumor is not necessary unless the size is very large, because most of them are benign in nature. However, the gastric submucosal tumor with more than 1 cm in diameter should be carefully and regularly followed up or biopsied because it cannot be assumed to be benign for any GIST more than 1 cm in size at the present time, safely.

    BACKGROUND/AIMS: The aim of this study was to investigate the immunohistochemical expression of bcl-2, bcl-xL, bax, and p53 proteins according to the pathological parameters such as grade of dysplasia, histological type, depth of invasion, lymph node metastasis, and TNM stage in the gastric adenoma and gastric adenocarcinoma. METHODS: Immunohistochemical staining using monoclonal bcl-2, bcl-xL, bax, p53 antibodies were performed on paraffin embedded specimens from forty-one gastric adenomas and 100 gastric adenocarcinomas. RESULTS: The expression rate of bcl-2 was higher in adenomas (34.2%), especially in high grade dysplasia (52.4%), than adenocarcinomas (2.0%). The expression rate of bcl-xL was higher in adenocarcinomas (55.0%) than adenomas (22%). The expression rate of the bax was higher in adenocarcinomas (58.0%) than adenomas (14.6%). In the adenocarcinoma, the bax expression was significantly related with the depth of invasion, lymph node metastasis, and TNM stage. The expression rate of p53 was higher in adenocarcinomas (64.0%) than adenomas (14.6%). CONCLUSIONS: Bcl-2 protein would be related with the development of gastric adenoma, especially with high grade dysplasia. Bcl-xL and p53 proteins would be involved in the development of relatively early stage of gastric adenocarcinoma but not in tumor progression. Bax protein would be involved in the development of gastric adenocarcinoma and related with depth of invasion, lymph node metastasis, and TNM stage.

    BACKGROUND/AIMS: Lymph node (LN) metastasis occurs in approximately 10% of patients with submucosally invasive colorectal carcinoma. This study was performed to determine the role of matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) production and microvessel formation on the LN metastasis in submucosally invasive colorectal carcinoma. METHODS: A total of forty-one subjects with surgically resected submucosally invasive colorectal carcinoma were included in this study. Immunohistochemical staining of MMP-2, MMP-9, TIMP-1, TIMP-2, and urokinase-type plasminogen activator were performed. Angiogenesis was evaluated by counting the number of microvessels in each pathologic specimen as identified by CD34 immunohistochemical staining. RESULTS: The depth of submucosal invasion was not significantly correlated with the expression of MMP-2, MMP-9, TIMP-1, TIMP-2, or urokinase-type plasminogen activator, but the microvessel count was significantly correlated with the absolute depth of invasion (r=0.312, p

    BACKGROUND/AIMS: Due to widespread use of computerized tomography (CT) scan to examine patients with variable disease or complaints, detection of incidental or unsuspected gastrointestinal abnormalities are not uncommon. Clinical significance of incidentally detected bowel wall thickening (BWT) on abdominal CT scan is uncertain at present. Despite the necessity for the clinical guidelines describing the evaluation of incidental bowel wall thickening on CT scan, there have been few studies concerning these radiological abnormalities. Our objective was to determine whether endoscopic evaluation is necessary for the evaluation of these abnormal findings. METHODS: This study evaluated one hundred and forty patients with incidentally detected BWT on abdominal CT scan in Inje University Sanggye Paik Hospital from 2001 to 2003. 102 patients of those were proceeded by endoscopic evaluation. Forty-eight patients had received upper endoscopy, 26 patients had colonoscopy, while 28 patients had sigmoidoscopy. RESULTS: Endoscopic work up revealed significant abnormalities in 83% of patients with incidental findings of the distal esophagus, 73% of patients with thickening of the stomach, 35% of patients with thickening of the right colon, and 71% of patients with thickening of the sigmoid colon and rectum. CONCLUSIONS: Although significant pathologic findings are less common in thickening of the right colon than other bowel wall thickening, all of these incidental findings on CT scan warrant further endoscopic evaluation.

    BACKGROUND/AIMS: In spite of increasing interests about nonalcoholic steatohepatitis (NASH), there are few reports about the ultrastructure of hepatocyte in this disease. The aim of this study was to clarify abnormal electron microscopic (EM) findings and related factors in NASH. METHODS: Total of fourteen patients who underwent liver biopsy due to steatohepatitis were included. Precise personal history was taken and variable blood tests such as liver function test, lipid profile, and serum iron study were done. Pathologic examination with light and electron microscopy was done by single pathologist. RESULTS: Eleven men and three women were included and mean age was 33.7+/-12.8 years. Nine patients drinking less than 40 g/week was grouped as "NASH group" and other 5 patients drinking more than 40 g/week and body mass index less than 25 was grouped as "ASH (Alcoholic Steatohepatitis) group". Polymorphism of mitochondria such as megamitochondria or loss of cristae was major abnormal EM findings and was more common in "NASH group" than "ASH group" (p=0.027). There was no significant clinical or pathological factors related with the presence of these abnormal EM findings. CONCLUSIONS: Polymorphism of mitochondria is major abnormal EM finding of steatohepatitis and is more common in NASH than ASH. And there is no significant clinical or pathological factors which could predict the presence of these abnormal EM findings.

    BACKGROUND/AIMS: p53 mutation is the most common genetic abnormality in human cancers. However, although it has been reported that p53 overexpression in hepatocellular carcinoma (HCC) is associated with the aggressive behavior of tumor, the prognostic significance of p53 overexpression in HCC remains controversial. The aims of the present study were to examine the correlations between p53 overexpression and the clinicopathologic parameters of HCCs, and to determine the prognostic significance of p53 overexpression in HCC. METHODS: Immunohistochemical analysis of p53 overexpression was performed in 105 consecutive cases of HCC who underwent curative hepatic resection. Survival curves were calculated using the Kaplan-Meier method and multivariate analysis of outcome predictors for HCCs was assessed by logistic regression analysis. RESULTS: p53 overexpression was observed in 20 of 105 HCCs (19.0%). Multivariate analysis identified significant correlations between p53 overexpression and microvascular invasion (p=0.027), liver cirrhosis (p=0.035), 1-year survival rate (p=0.016), multiple tumors (p=0.014), and the presence of tumor capsule (p=0.010). The 2-year survival rate was poorer in patients without tumor capsule (p=0.043). CONCLUSIONS: Our results show a positive association between p53 overexpression and microvascular invasion in HCC, and indicate that p53 overexpression is a poor prognostic factor of survival, especially within 1 year after liver resection in HCC patients.

    Villous tumors of the stomach are somewhat rare with approximately 100 cases only reported in the literatures and have tendency to undergo malignant transformation as high as 72%. They are frequently multiple and associated with other gastrointestinal neoplasm. Thirty percent of them are associated with an independent gastric carcinoma. Gastric villous tumor has certain radiologic characteristics that may permit a preoperative diagnosis and also some distinctive clinicopathologic features which make early diagnosis and proper treatment possible. We experienced a 64-year-old man who complained of prolonged general weakness, weight loss for several months and left upper quadrant pain for four days. Esophagogastroduodenoscopy and barium study of upper gastrointestinal tract demonstrated typical, irregular, frond-like surfaced villous tumor occupying nearly whole gastric lumen and located eccentrically along the lesser curvature side. Endoscopic biopsy of the tumor revealed a gastric villous tumor with carcinomatous change.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies. Many factors are considered to be etiology associated with HCC; the important factors are hepatitis B and C viruses and alcohol. Cirrhosis is present in the majority of patients with HCC. It is assumed that all diseases, which lead to liver cirrhosis, may be complicated by the development of HCC. We report a 36-year-old man with HCC which developed from cardiac cirrhosis caused by constrictive pericarditis in whom both hepatitis B virus and hepatitis C viral marker tests were all negative. CT scan of his heart showed pericardial calcification with diastolic dysfunction of right ventricle. Abdominal CT scan revealed mottled mosaic pattern of contrast enhancement of liver parenchyme and two hepatic lesions that were considered to be HCCs. Left lateral segmentectomy of liver was performed. There were two well-circumscribed masses which were confirmed to be HCC and the remaining hepatic parenchyma showed bridging fibrosis between central zonal regions. To our knowledge, this is the first case of HCC complicating cardiac cirrhosis in Korea.
