Recent advent of non-surgical treatment for gallstones desires accurate in vivo analysis of chemical composition to select optimal candidate. As preliminary work, we undertook in vitro CT examimation of the surgically removed 53 gallstones and compared CT pattern with chemical compsotion. Those results were correlated with in vitro lithotripsy of the gallstones. The CT appearances were classified as follows: Laminated (43%), dense (32%), rimmed (11%), isodense (8%) and faint (6%). Dense pattern contains high calcium content. As CT density increased, calcium content increased, but cholesterol content decreased proportionslly. The number of shock waves to breakdown the gallstone ]ess than 2 mm in size, has increased as stone volume and cholesterol content increases but did not have any correlation with calcium content level. As a result, the CT exmination is very sensitive to detect small amount of calcium content in gallstones and CT pattern and density of the gallstones are well correlated with chemical compsotion and therefore in vivo CT exmination for ESWL candidate is desirable.

N/A Exudative ascites should initiate an evaluation for peritoneal processes, most importantly infection and tumor. And the pathological diagnosis is required for a approapriate treatment in most cases. To assess the diagnostic accuracy and complication rates of diagnostic laparoscopy in patients with exudative ascites we studied in 73 patients with exudative ascites retrospectively. Thirty three patients had malgnancy related ascites, and peritoneal carcinomatosis was confirmed in thirty one patients. Twenty seven patients had tuberculous peritonitis, and thirteen patients had miscellaneous causes, among them eight patients had underlying liver cirrhosis and clinically spontaneous bacterial peritonitis were suspected in three patients in whom bacteria were cultivated in ascites. Pancreatic pseudocyst and leakage into peritoneal cavity was confirmed by endoscopic retrograde pancreatography in one case, but the remained four cases had not known the diagnosis. The most common primary cancer was gastric carcinoma which was diagnosed in fourteen patients, and then ovarian cancer in five patients, colon cancer in four patients, pancreatic cancer in three patients, mesothelioma in one patient and unknown origin in four patients. Cytology evaluation of the ascitic fluid was positive for tumor cells in 62% of patients with peritoneal carcinomatosis. Blind Cope needle biopsy yielded positive diagnosis of neoplastic or tuberculous in 65.4 per cent of rases. The major and minor complication rates of laparoscopy were 0% and 26.4%, respectively, with no fatalities. These findings compare favorably with general experience. We conclude that laparascopy is relatively safe and accurate diagnostic method of choice in exudative ascites, especially in cases when other non-invasive methods were failed.

Background: It has been known that the sero- logic markers of infectivity and viral replication in patients with hepatitis B virus(HBV) infection are hepatitis B e antigen(HBeAg), HRV DNA and HBV DNA polymerase. Methods: In order to clarify the relationship between chronic liver diseases and HBV infection, and the mechanism of chronicity in HBV related liver diseases, the expression patterns of hepatic HBeAg by imrnunohistochemical stain and histologic activity index(HAI) were studied from 10% formalin fixed paraffin embedded tissues in 114 patients performed liver biopsy. Results: The results were as follows: 1) Incidence of serum HReAg positivity in HBsAg positive patients was 74.6% and that of hepatic HBeAg expression was 77.6% among serum HBeAg positive cases. Hepatic HBeAg expression was 72.4% in serum HBeAg negative cases. 2) In serum HBeAg positive cases, almost all infected hepatocytes exhibited cytoplasmic HBeAg expression and half of patients showed nuclear HBeAg expression, but cytoplasmic HBeAg expression was solely predominant in serum HBeAg negative cases. Hepatic HBeAg expression showed a decreasing trend from AVH and CPH, through CAH, to cirrhosis with or without HCC, which was a consistent finding with serum HBeAg in decreasing manner. Hepatic HBeAg expreassion was highly sustained in about 60-90% of cases, regardless of duration of their illnesses. 3) HAI showed slighf3y higher tendency in patients with hepatic HBeAg negative expression than in positive cases. Conclusion: The above results suggest that HBeAg may play a role as a viral target antigen for immune-mediated liver injury and may be also related to the pathogenetic mechanism of chronicity in chronic hepatitis B.

Objective : Hepatic dysfunction frequently occurs in patients with hematologic malignancies and aplastic anemia who receive intensive chemotherapy or bone marrow transplantation (BMT). The role of laparoscopic liver biopsy in patients with hematologic disorders is very important to determine the etiological factors and to make treatment decisions. The aim of the present study was to evaluate the possible causes of liver disease in patients with abnormal liver function tests. Methods : Laparoscopy guided liver biopsy was performed in 38 subjects who were receiving intensive cytotoxic therapy with BMT or without BMT. Two to three pieces of liver tissues were obtained in each patients using Vim-Silverman needle with electrocoagulation on biopsy site. Platelet transfusions were given if platelet count was less than 50,000/mm3. 39 biopsies were obtained in 38 patients. Results : At the time of liver biopsy, platelet count was 170,000±138000/mm3 (range: 42,000 - 798,000/mm3). No procedure-related complications were observed. Biopsy findings after BMT (n=16) revealed graft versus host disease (GVHD) (n=9), drug induced hepatitis (n=6), veno-occlusive disease (n=2), viral hepatitis (n=1), and nonspecific reactive hepatitis (n=1). 3 patients of GVHD associated with other liver diseases such as drug-induced hepatitis, veno-occlusive disease and chronic active hepatitis B. The authors compared histologic diagnosis with laparoscopic findings. Laparoscopic findings of the liver surface were classified by Shimada's code number system. 5 patients who were biopsed before BMT showed cholestasis and fatty changes and it was possible to be treated with allogenic BMT. Histologic diagnosis in patients without BMT (n=18) showed viral hepatitis (n=6), drug induced hepatitis (n=5), non-specific reactive hepatitis (n=1), and others (n=6). In 12 cases (31%) laparoscopic liver biopsy led to a change in medical management. Conclusion : Laparascopic liver biopsy has been proven to be an effective means of assessing the cause of liver dysfunction in patients with hematologic disorders. The diagnosis obtained at laparoscopic liver biopsy could be changed the therapeutic plan in 12 of 39 (31%) patients.

N/A To evaluate the efficacy and safety of natural interferon alpha (Green Cross Co.) in ten patients with chronic active hepatitis (CAH) type B, a course of 12 weeks natural IFN-alpha was given three times weekly by subuctaneous injection at a dose of 3 million unit (MU) In ten patients with HBeAg positive CAH type B, DNA polymerase and aminotransferase activities were assessed and compared before, during and after natural IFN-alpha administration. We followed up at least for 12 to 24 months. The peripheral blood white cell (WBC), granulocyte and platelet count were also checked before and after therapy. The results were as follows: 1) During administration of natural interferon alpha, DNA polymerase activities were declined significantly within first week and sustained and negative conversion in 70% (7/10). After administration of interferon, DNA polymerase activities were rebounded and negative in only 30% (3/10) at 6 months therapy. 2) Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were decreased significantly from 6 and 12 weeks after therapy, respectively (p<0.05) though transient increament of just after therapy. 3) During follow up period, loss of HBe Ag was found in 5 cases (50%). Of these, seroconversion (Anti-Hbe) of HBe Ag was found in 3 cases (30%). In 2 out of these 3 cases, loss of anti-Hbe and reappearance of HBe Ag in 1case, and sustained increament of serum alanine aminotransferase (ALT) were observed in 1 case, which were revealed progressive liver changes despite loss of Hbe Ag and seroconversion (Anti-HBe) during follow up period. HBe Ag reappeared in 2 cases, which were not seroconversion (Anti-HBe). Namely, loss of HBe Ag and seroconversion (Anti-HBe) and normal serum transaminase were observed in 1 case (10%). 4) There was no significant clinical, hematological, biochemical changes after natural interferon alpha therapy. We concluded that subcutaneous injection of 3 MU natural interferon alpha was safe and effective in decreament of DNA polymerase and transaminase level transiently in patients with CAH type B. But long term therapy more than 3 months will be necessary for the eradication of Hbe antigenemia and clinical improvement for a long time, and repeated biopsy for the exact assessment of results.

Aplastic anemia is rare, severe complication of viral hepatitis. Over 200 cases have been reported in the literature, but only recently the virological studies have been carefully implicated. There have been reports of fatal aplastic anemia associated with type-A virus, type-B virus and non-A, non-B hepatitis. We report a 35-year-old man, who found to have severe aplastic anemia associated with fulminant hepatitis: Virological studies suggested that it was probably non-A, non-B hepatitis.
