RESUMEN
BACKGROUND AND AIMS: Bleeding from esophageal and gastric varices is a fatal event in patients with liver cirrhosis and portal hypertension. However, the effects of Helicobacter pylori (H. pylori) infection on esophagogastric variceal bleeding are not known. The present study was aimed to elucidate the role of H. pylori infection in esophagogastric variceal bleeding. METHODS: The subjects were 196 cirrhotic patients who were admitted to the Kurume University Hospital to treat their esophagogastric varices consisted of 95 with acute bleeding and 101 with nonbleeding but high risk of bleeding. For the diagnosis of H. pylori infection, a (13) C-urea breath test was used, and serum pepsinogen (PG) I and II levels and the PG I/II ratio were also measured. RESULTS: Esophagogastric variceal bleeding was seen in 34.9% (n = 30) of the H. pylori-infected patients (n = 86) and in 59.1% (n = 65) of the noninfected patients (n = 110) (P < 0.0007). There was no significant difference in the infection rate between the bleeding sites of the esophagus and the stomach. The serum PG I and II levels and the PG I/II ratio were 65.6 ng/dL, 14.7 ng/dL, and 4.4, respectively, for the bleeding patients (n = 95), and 43.7 ng/dL, 17.7 ng/dL, and 3.1 for the nonbleeding patients (n = 101). Thus, the nonbleeding patients had significantly higher rate of H. pylori infection and lower acid secretion than bleeding patients (0.001). In addition, multivariate logistic regression analysis showed a significant negative association between H. pylori infection and esophagogastric variceal bleeding. CONCLUSIONS: These results suggest that H. pylori infection has a protective effect against esophagogastric variceal bleeding through the induction of gastric mucosal atrophy and concomitant hypoacidity.

BACKGROUND/AIMS: Esophageal varices are often seen in cirrhotic patients. Because endoscopic therapy for esophageal varices forces such patients to go on an extended fast until the endoscopic therapy occurs, physical and psychological stresses are induced. The aims of this study were to investigate the effects of a nutritional supplement before endoscopic therapy on such stresses, and on the safety of therapy. METHODOLOGY: Thirty-six cirrhotic patients with esophageal varices were enrolled in this study and classified into two groups. In the fasting group, no energy was supplied to patients prior to endoscopic therapy (n=18). In the supplement group, a supplement of 200kcal was given prior to endoscopic therapy (n=18). The effects of the supplement on the safety of therapy and on stresses were evaluated by the endoscopist and by the self-rating questionnaire. RESULTS: There were no significant differences in age, gender, BMI, or Child-Pugh score between the two groups. There was no interference with endoscopic therapy in the supplement group. Although physical symptoms were not significantly different between the two groups, stress scores for hypodynamia, was significantly lower in the supplement group than in the fasting group. CONCLUSION: We first demonstrated that the supplementation before endoscopic therapy does not interfere with endoscopic treatment for esophageal varices in cirrhotic patients. Supplementation improves fasting-related hypodynamia.

BACKGROUND AND AIMS: It is well known that a large portosystemic shunt develops during portal hypertension. In this study, we studied the long-term effects of a large splenorenal shunt (SRS) on liver function and survival. METHODS: The subjects were divided into three groups: an SRS (-) group consisting of cirrhotic patients without SRS; an SRS (+) group consisting of patients with gastric fundal varices and SRS; and a balloon-occluded retrograde transvenous obliteration (B-RTO) group with a completely obliterated SRS by B-RTO. We compared the following among these groups: the total bilirubin levels, serum albumin levels, prothrombin times, changes in Child-Pugh scores, and survival rates. RESULTS: After a 3-year follow-up period the Child-Pugh scores showed significant differences among the SRS (+), SRS (-), and B-RTO groups. The score worsened for the SRS (+) group. The cumulative survival rates were significantly different between the SRS (+) and SRS (-) groups and between the SRS (+) and B-RTO groups. The vital prognosis worsened for the SRS (+) group. CONCLUSIONS: The presence of a large splenorenal shunt (portosystemic shunt) was indicated to lower liver function and vital prognosis. B-RTO, which completely obliterates large splenorenal shunts, inhibited the lowering of hepatic functional reserve and the worsening of vital prognosis, indicating a protective role. Liver pathology and the presence of a large portosystemic shunt each separately result in progressive liver dysfunction and worsen the survival rate. We found that such a pathological condition had occurred due to a large portosystemic shunt, and it should be called 'portosystemic shunt syndrome.'

Fibrates are widely used for treatment of hyperlipidemia. It has been reported that gallbladder stones are formed by administration of clofibrate. It is thought that fenofibrate can cause the formation of gallbladder stone as a side effect. We encountered a patient with hyperlipidemia in whom a gallbladder stone was detected by computed tomographic scanning 3 months after the start of administration of fenofibrate during follow-up observation by blood biochemical examination and computed tomographic scanning. This case report will be of great value and importance.

Isolated gastric varices (IGV) have a lower risk of bleeding than esophageal varices, however IGV bleeding is associated with a higher mortality than bleeding of esophageal varices. In recent years, two widely used treatments for IGV have been balloon-occluded retrograde transvenous obliteration (B-RTO) and endoscopic injection sclerotherapy (EIS) using cyanoacrylate or ethanolamine oleate (EO). This study compared these two treatment methods for IGV. The subjects were 112 patients who were treated at our hospital for IGV bleeding between October 1990 and December 2003. Forty-nine (49) patients were treated with B-RTO and 63 patients with EIS. These two patient groups were compared as regards content of treatment, post-treatment incidence of variceal bleeding, incidence of IGV rebleeding, survival rate, cause of death, and complications. Multivariate analysis was performed on post-treatment variceal bleeding and survival. Although EO was used in higher amounts in the B-RTO group than in the EIS group, the B-RTO group had a significantly lower number of treatment sessions and a significantly shorter treatment period (p<0.05). The EIS group had significantly more patients with IGV rebleeding after treatment than the B-RTO group. Treatment method was the only independent prognostic factor of IGV bleeding after treatment (p=0.024). The two groups did not differ significantly in the percentage of patients with aggravated esophageal varices after treatment. Bleeding from ectopic varices was not observed in any patient. There was no significant difference in survival by treatment method. The presence of hepatocellular carcinoma was the only independent prognostic factor for survival (p=0.003). It is concluded that B-RTO was more effective than EIS in the eradication of IGV and prevention of IGV recurrence and rebleeding.

This study examined 19 patients with portosystemic shunt encephalopathy caused by a splenorenal shunt (SRS), which was treated with balloon-occluded retrograde transvenous obliteration (B-RTO). Long-term treatment outcomes were evaluated based on hepatic functional reserve and vital prognosis. Encephalopathy improved in all patients after shunt embolization and closure. Albumin, serum ammonia, and the Child-Pugh score, a measure of liver function, were significantly improved 3 years after B-RTO, and exacerbation of damage to liver function was avoided (p<0.01). During the follow-up period, three patients died from liver failure and two patients from hepatocellular carcinoma. Patients had a poor prognosis if their albumin levels were less than 2.8 mg / dL before B-RTO (p<0.05). Encephalopathy patients had complete response to B-RTO, but long-term prognosis was affected by hepatic functional reserve before B-RTO and by concurrent hepatocellular carcinoma. The results of this study suggest that in patients with SRS, it is important to perform B-RTO at an early stage when the hepatic functional reserve is still satisfactory.

BACKGROUND AND AIM: Balloon-occluded retrograde transvenous obliteration (B-RTO) is a novel therapeutic method for the treatment of large gastric fundal varices with spontaneous splenorenal shunt (SRS). However, the effects of B-RTO on liver function remain unknown. METHODS: Fourteen patients with portal hypertension and gastric varices with SRS were studied, consisting of four patients with acute bleeding, five with high-risk varices, and five with refractory portosystemic encephalopathy. Hepatic venous catheterization was performed to evaluate hepatic blood flow and liver function using the continuous indocyanine green (ICG) infusion method. To assess the metabolic activity of the hepatocyte, the intrinsic clearance of ICG was calculated. In all patients, endoscopic study was performed before and 1 week and 1 month after the B-RTO, and followed every 6 months thereafter. After baseline measurements, B-RTO was performed. Four weeks after the B-RTO, the same catheter measurements were repeated. RESULTS: The B-RTO was successful in all patients. Contrast-enhanced computed tomography showed complete obliteration of the SRS prior to the follow-up measurements. Endoscopic eradication of the fundal varices was obtained 6 months after B-RTO in all patients and encephalopathy was improved within 1 week after B-RTO. Following the B-RTO, hepatic blood flow (441 +/- 214 vs 668 +/- 299 mL/min, P < 0.0001) and the intrinsic clearance of ICG (233 +/- 123 vs 285 +/- 148 mL/min, P < 0.05) were significantly increased. Furthermore, intrahepatic resistance decreased after the B-RTO (P < 0.005). CONCLUSION: From short-term assessment, B-RTO increases hepatic blood flow and improves the metabolic activity of the liver in patients with portal hypertension.
