BACKGROUND: The prognosis following surgery for gastric cancer has been markedly improved as a result of early diagnosis and advancements both in operative techniques and perioperative management. However, gastrointestinal surgery in the presence of hepatic cirrhosis has shown high operative morbidity and mortality due to severe perioperative complications, such as bleeding, lymphorrhea, anastomosis leakage, hepatic failure, fluid retention, acute renal failure and multiple organ failure. Recently, the frequency of gastric cancer involving liver cirrhosis has been increasing, especially early gastric cancer cases. METHODS: From June 1995 to December 1997, a total of 410 patients with gastric cancer were treated surgically. Among them, 9 cases with liver cirrhosis underwent gastric resection. RESULTS: Three major postoperative complications occurred in 2 patient, anastomosis leakage in one, and bleeding in both. CONCLUSIONS: The purposes of this study were to assess the causes of complications and to decide the appropriate operation type for improving the prognosis for these patients with liver cirrhosis.

Acute-on-chronic liver failure (ACLF) is an increasingly recognized distinct disease entity encompassing an acute deterioration of liver function in patients with chronic liver disease. Although there are no widely accepted diagnostic criteria for ACLF, the Asia.Pacific Association for the Study of the Liver (APASL) and the American Association for the Study of Liver Disease and the European Association for the Study of the Liver (AASLD/EASL) consensus definitions are commonly used. It is obvious that the APASL and the AASLD/EASL definitions are based on fundamentally different features. Two different definitions in two different parts of the world hamper the comparability of studies. Recently, the EASL-Chronic Liver Failure Consortium proposed new diagnostic criteria for ACLF based on analyses of patients with organ failure. There are areas of uncertainty in defining ACLF, such as heterogeneity of ACLF, ambiguity in qualifying underlying liver disease, argument for infection or sepsis as a precipitating event, etc. Although the exact pathogenesis of ACLF remains to be elucidated, alteration of host response to injury, infection, and unregulated inflammation play important roles. The predisposition, infection/inflammation, response, organ failure (PIRO) concept used for sepsis might be useful in describing the pathophysiology and clinical categories for ACLF. Treatment strategies are limited to organ support but better understanding of the pathophysiology is likely to lead to discovery of novel biomarkers and therapeutic strategies in the future.

Acute fatty liver of pregnancy (AFLP) is unusual but can potentially progress to overwhelming liver failure, resulting in maternal and fetal death. AFLP is characterized by the accumulation of microvesicular fat within hepatocytes. We report the case of a 37-year-old woman at 36 weeks' gestation with a twin pregnancy who was admitted with the diagnosis of intrauterine fetal death of one baby. The patient showed profile of AFLP on her laboratory findings and underwent emergency cesarean section. Then she progressed to cryptogenic fulminant hepatic failure and underwent successful orthotopic liver transplantation on 9th day of admission. This case demonstrates that liver transplantation is a feasible therapeutic option for the treatment of patients with this condition.

Acute viral hepatitis A has recently become a major public health problem in Korea, and the incidence of symptomatic hepatitis A is growing rapidly. With improvements in socioeconomic conditions and environmental hygiene, the chances of exposure to hepatitis A virus (HAV) during childhood have decreased and, in turn, the proportion of young adults with positive anti-HAV has significantly decreased. This has led to the incidence of symptomatic acute hepatitis A increasing since the late 1990s. The incidence of serious complications including fulminant hepatic failure and acute kidney injury has also showed an increasing trend. Variation of the genotype of virus isolated from recent hepatitis A patients suggests an inflow of the hepatitis virus from other countries. In this review article, we present the situation and epidemiology of hepatitis A in Korea, and recommend further investigation and policies for vaccination on a national level.

Objective: To explore the characteristics of Banna miniature pig liver failure induced by amanita exitialis. Methods: From September to October 2020, a reverse high performance liquid chromatography (RP-HPLC) method was used to determine the toxin content of amanita exitialis solution, and 2.0 mg/kg amanita exitialis solution (α-amanitins+β-amanitins) was administered orally to Banna miniature pigs. Toxic symptoms, blood biochemical indexes and histopathological changes of liver, heart and kidney were observed at each time point. Results: All Banna miniature pigs died within 76 h of exposure, and different degrees of digestive tract symptoms such as nausea, vomiting and diarrhea appeared between 6 and 36 h. The biochemical indexes of alanine aminotransferase, aspartate aminotransferase, total bilirubin, lactate dehydrogenase, myoglobin, creatine kinase isoenzyme, blood urea nitrogen and creatinine increased significantly at 52 h after exposure, and the differences were statistically significant compared with 0 h (P<0.05). The bleeding of liver and heart was obvious under macroscopic and microscopic observation, hepatocyte necrosis, renal tubule epithelial cell swelling. Conclusion: Large dose of amanita exitialis can cause acute liver failure of Banna miniature pigs, which is in line with the pathophysiological characteristics of acute liver failure, and lays a foundation for further research on the toxic mechanism and detoxification drugs of amanita exitialis induced liver failure.

BACKGROUND/AIMS: There have been scant reports on the prognostic factors of fulminant hepatic failure for selecting the patients who need liver transplantation. We investigated the clinical features and prognostic factors throughout the clinical course of the disease in Korean patients with fulminant hepatic failure. METHODS: Between 1992 and 2003, a total of 60 patients with fulminant hepatic failure were divided into the survival group and the non-survival group, and these groups were compared according to gender, age, etiology, values of the laboratory tests, grade of the encephalopathy that was obtained at the time of admission and the worst clinical status (hepatic encephalopathy). RESULTS: The mean age of the total patients was 40.9 years (M:F=31:29) and the survival rate was 28.3% (n=17). Drugs (n=25, 12 herbal medicines) and viral infection (n=24, 18 HBV infection) were most common causes. On univariate analysis, the WBC, AST, ALT, total bilirubin and HE IV stage at the time of admission were the significant factors for a poor prognosis. Total bilirubin, albumin and HE IV stage also remained as significant factors at the time of the worst clinical status. On multivariate analysis, total bilirubin (P=0.033) and ALT (P=0.042) at admission were the prognostic factors, and the progression to HE IV stage (P=0.019) or hypoalbuminemia (P=0.028) during hospitalization represented the significant factors for a poor prognosis. CONCLUSIONS: In contrast to Western countries, HBV infection and herbal medicines were major causes of fulminant hepatic failure in Korea. The total serum bilirubin level and progressive hyperbilirubinemia with HE (stage IV) during hospitalization seemed to be the most important prognostic factors, and liver transplantation should be considered before the patient reaches this status.

Tetrachloroethylene is a chlorinated solvent that is primarily used in dry cleaning and degreasing operations. Although the hepatotoxicity caused by tetrachloroethylene has been well documented in literature, it is rarely considered as a cause of acute liver failure. We report a case of a 39-yr-old man who was admitted to our hospital for acute liver failure due to tetrachloroethylene exposure. Histological examination of the liver revealed massive hepatic necrosis, prominently, in zone 3 of the hepatic lobules. The patient underwent supportive treatment along with 3 sessions of plasmapheresis, and consequently, he presented a favorable outcome. Repeat liver biopsy performed 6 months after the patient's discharge showed architectural distortion with postnecrotic cirrhosis. Physicians should be aware of the possibility of acute liver failure induced by tetrachloroethylene. Early plasmapheresis can be effective for individuals with sufficient capacity for hepatocyte regeneration.
