A clinical study on efficacy of prophylactic sclerotherapy for esophageal varices was carried out on 220 patients with unresectable hepatoma treated with TAE. They were classified into 3 groups: 1) Prophylactic group with prophylactic sclerotherapy for RC sign positive varices (45 cases), 2) Non-prophylactic group with RC sign positive varices without prophylactic sclerotherapy (31 cases), 3) RC negative group in which RC sign was negative in whole time (144 cases). Although atypical RC sign or venous dilatation was noticed in 54% of patients in prophylactic group at 1-year after sclerotherapy, cumulative bleeding rates after detection of RC sign positive varices in prophylactic group (27% at 2-years) were significantly lower (p < 0.001) than those in non-prophylactic group (91% at 2-years). The incidence of death by variceal bleeding in prophylactic group (6%) was significantly lower (p < 0.005) than that in non-prophylactic group (36%). 50% survival period of prophylactic group (25.0 months) was significantly longer (p < 0.001) than that of non-prophylactic group (12.5 months), and there was no significant difference of 50% survival period between prophylactic group and RC negative group (21.6 months). We conclude that, prophylactic sclerotherapy not only decrease incidence of variceal bleeding and of death due to bleeding, but also improve survival rate in hepatoma patients with RC sign positive esophageal varices.

Endoscopic intravariceal injection sclerotherapy (EIS) using sclerosant mixed with contrast medium was done in 100 patients without hepatocellular carcinoma. They were followed longer than 12 months (mean; 58 +/- 29 months) after EIS. The recurrence rate of esophageal varices in cases with complete eradication (n = 79) and cases with incomplete eradication of (n = 21) was 8.9% and 85.7%, respectively (p < 0.01). In 21 cases, complete eradication was achieved by intravariceal injection and additional therapy using paravariceal injection was not performed. The recurrence rate of this group was only 4.8%. Endoscopic varicealography during injection sclerotherapy were evaluated in 91 cases. At final session of EIS, narrowing of diameter (less than 1 mm) and irregularity of vessel walls were observed in small vessels (devastated vessels). Appearance rate of devastated vessel in 75 cases with completely eradicated esophageal varices was 65.3%. In contrast, among 16 cases with incomplete eradication of varices, devastated vessels were seen only in 6.3% (p < 0.01). It is concluded that the important point in preventing the recurrence of esophageal varices after EIS was the complete eradication of esophageal varices by intravariceal injection sclerotherapy resulting in the eradication of the routes to esophageal varices from port-splenic venous system. For the sake of accomplishment of this treatment, appearance of devastated vessel is very useful.

The reasons for the high frequency of endotoxaemia in cirrhosis, whether poor liver function or abnormal portal circulation, are not known. Accurate measurement of endotoxin itself is difficult. Instead, in this study an enzyme-linked immunosorbent assay was used to measure levels of IgA, IgG and IgM antibodies to endotoxin in patients with chronic liver disease and underlying hepatic viral infection. The relationships between the results and clinical symptoms or the presence of a portal systemic shunt were investigated. The median level of IgA antibodies was not different in patients with chronic hepatitis and those with cirrhosis, and the same was found for IgM, but the median level of IgG antibodies was significantly higher in the patients with cirrhosis. When patients with cirrhosis were grouped by the presence or absence of ascites or hepatocellular carcinoma, no significant difference was observed in any of these antibody levels. However, in cirrhotic patients with varices, the level of IgG antibodies to endotoxin was significantly higher than in patients without varices. For evaluation of the portal systemic shunt, the per-rectal portal shunt index was calculated. There was a significant correlation (R = 0.431, P < 0.001) between the per-rectal portal shunt index and the level of IgG antibodies to endotoxin. That is, the degree of abnormality in the portal haemodynamics was correlated with the level of IgG antibodies to endotoxin in patients with liver disease.

Between 1988 and 1990 an unblinded, randomized trial of terlipressin or vasopressin plus transdermal nitroglycerin, as part of a treatment strategy including emergency sclerotherapy for actively bleeding varices, was conducted during 165 admissions in 137 patients with cirrhosis and upper digestive bleeding. Eighty-four patient admissions were assigned to terlipressin (2 mg every 6 h) and 81 to vasopressin (0.4 to 0.8 unit per min) plus transdermal nitroglycerin (20 to 80 mg). The two groups were comparable for relevant clinical data, but there were slightly more patients with hepatocellular carcinoma or terminal conditions in the terlipressin group. After the 24-h study period, failure to control bleeding was 20/84 (25%) in the vasopressin and 14/81 (17%) in the terlipressin group (p = 0.19). Corresponding figures for patients bleeding from varices (emergency sclerotherapy in 43 and 45, respectively) were 13/55 (24%) and 5/56 (9%; p = 0.035), from other sources 5/16 (31%) and 2/15 (13%; p = 0.23), from undefined sources 2/10 (20%) and 7/13 (54%; p = 0.1). In a logistic multivariate regression model the odds ratio for terlipressin adjusted for prognostic factors was 0.45 (p = 0.07). There were seven major side effects requiring treatment discontinuation in the vasopressin and one in the terlipressin group. These results suggest that terlipressin alone is as effective as vasopressin plus transdermal nitroglycerin, with less severe side effects, in 24-h control of upper gastrointestinal bleeding in patients with cirrhosis.

Bleeding esophageal and gastric varices caused by portal hypertension with (group I) or without (group II) liver damage should be treated primarily by sclerotherapy or shunt-operation if there is no indication for liver transplantation. In the case of rebleeding associated with thrombosis of portal-/mesenteric or splenic vein we performed in 17 patients a complete devascularisation of the proximal stomach, cardia and distal esophagus (Hassab's operation 1967) (N = 5--group I; N = 12--group II). In group I, the early postoperative (0-30 days p.o.) course was complicated by one necrosis of the gastric fundus. In group II, postoperative bleeding from gastric varices was noted in four patients, three of which were treated by proximal gastric resection; two of twelve patients died. No serious complications in the long-term follow-up (min. 171--max. 1217 days) occurred in group I. In group II, half of the patients died (1 bleeding episode, 1 liver coma, 1 hepatocellular carcinoma, 2 other causes). The operative risk and the long-term prognosis are essentially influenced by the basic disease and to a much lesser degree by the type of operation. The devascularisation of the esophago-gastric junction is per se a low risk intervention which is always practicable, even in high risk patients.

Eleven liver cirrhosis patients with variceal bleeding and/or ascites were treated by transjugular intrahepatic portosystemic shunt. Four of the patients were combined with hepatoma, and 2 had portal thrombosis. Ten of the patients were successfully achieved TIPS, but one patient who had portal thrombosis was failed because of portal vein occlusion; success rate of 90%. An average decrease of 14mmHg in portal vein pressure was measured in the 10 patients. All of the successful patients including 4 with hepatoma were observed the disappeared or diminished varices and ascites without technical complication. Mild encephalopathy was encountered in 2 patients but who responded well to medical therapy. Three dimension MRA before TIPS was helpful for understanding the anatomical relationship between portal vein and hepatic vein. It is concluded that TIPS is an effective and safe treatment, indicating for the patients who have uncontrollable variceal bleeding and/or ascites even with hepatoma.

Prognostic factors of the outcome of upper gastrointestinal bleeding in patients with cirrhosis are insufficiently defined. Pertinent clinical, biochemical, and endoscopic data of 332 upper gastrointestinal bleedings in 268 patients with cirrhosis observed in the participating centers during 31 months were recorded. Clinical data were analyzed until 40 days after bleeding. A further set of 82 bleedings was used as a validation group. Ninety-two of the 268 patients died within the time of the study, and 28 of the 82 patients of the validation group died. According to a stepwise logistic regression analysis, s-creatinine, ascites on admission, previous diagnosis of hepatocellular carcinoma, s-bilirubin, prothrombin index, varices as definite or probable source of bleeding, gender, and presentation with hemathemesis were the best set of covariates for predicting outcome. From them a prognostic index was developed and validated in the 82 further bleedings. Sensitivity and specificity in the cumulated training and test sets were 75 and 80%, respectively. In the present material, the prognostic index was significantly more efficient than Child-Pugh score or the prognostic index proposed by Garden et al. These data show that it is possible to predict the outcome of upper gastrointestinal bleeding in cirrhosis on the basis of few easily available data. The prognostic index we proposed and validated may become useful to predict the outcome of a bleeding and to select or stratify patients in clinical trials.

Ultrasound is now widely used in the diagnosis of liver diseases. Applications of ultrasound in the diagnosis of liver cirrhosis are reviewed in this paper. Characteristic findings of liver cirrhosis in ultrasound are nodular liver surface, round edge, and hypoechoic nodules in liver parenchyma which represent regenerative nodules of cirrhotic liver. Detection of hypoechoic nodule more than 10 mm is important in the early diagnosis of hepatocellular carcinoma. Detection of splenomegaly, ascites, and portosystemic collaterals is possible by ultrasound. Evaluation of portosystemic collaterals is beneficial in the management of esophagogastric varices and portosystemic encephalopathy. Ultrasound is useful in the non-invasive diagnosis and long-term management of cirrhotic patients.

The most common etiogenic disease of portal hypertension that we experience is liver cirrhosis, which accounts for 84% of all cases. In patients with portal hypertension, congestion by portal blood due to cirrhosis causes a rise in portal pressure and development of collateral circulation between the portal system and the postcaval system is observed. Esophageal varices are associated with higher mortality than any other symptom of portal hypertension and are an important consideration in treatment. When emergency endoscopic examination and diagnosis show esophageal variceal bleeding, the varices must be constricted directly using a Sengstaken-Brakemor tube. If hemostasis is maintained, medical and surgical procedures can be performed after the recovery of body strength. Endoscopic Injection Sclerotherapy (EIS) has recently been widely carried out to prevent variceal bleeding and its application is increasing. However, treatment with EIS alone is not sufficient in terms of long-term efficacy, and surgical treatment is effective, especially in patients with gastric varices or splenomegaly. For Child A and B groups, both with good liver function, non-shunting operation, especially, the SUGIURA procedure, shows a marked effectiveness on varices. For group Child C, EIS is selected. The newly-developed Transjuglar Intrahepatic Portasystemic Shunt (TIPS), is being used, recently. For hepatic insufficiency, liver transplantation is expected to be one of the method for future treatment. Cirrhosis is also commonly accompanied by hepatoma, and this must be taken into consideration in treatment.

Since April 1985, we have performed a multidisciplinary therapy consisting of partial splenic embolization (PSE), percutaneous transhepatic obliteration (PTO) or transileocolic vein obliteration (TIO), and endoscopic injection sclerotherapy (EIS) for patients with severe gastroesophageal varices and those with a portacaval shunt associated with portal hypertension. In this study, PSE and percutaneous transhepatic portography (PTP) were performed at the same time in seven liver cirrhosis patients with hypersplenism, gastroesophageal varices, or hepatocellular carcinoma. The changes in portal blood flow/pressure and hemodynamics were examined by a thermodilution method. The effects of PSE on blood biochemical parameters such as the platelet count, ICG R15, redox tolerance index (RTI), and oral glucose tolerance test (75 g OGTT) were also evaluated. PSE induced a decrease in the blood flow of the splenic artery and in the splenic vein pressure without decreasing the portal blood flow. The platelet count in the peripheral blood and the RTI increased significantly. These results suggest the possibility that PSE may reduce the potential perioperative risk in hepatocellular carcinoma complicated with liver cirrhosis.
