    Notes: Abstract After excluding terminally all patients, we evaluated a total of 718 patients treated with endoscopic injection sclerotherapy. They involved 350 episodes of acute hemorrhage and 368 prophylactic procedures in patients with risky varices. The 1-year cumulative survival rate was significantly lower in the acute hemorrhage group than in the prophylactic group (P〈0.05). The difference in survival between the two groups was primarily due to the number of deaths in the first 2 months after sclerotherapy (20.1% vs 0.8%,P〈0.0005). Improvements in the sclerotherapy technique significantly reduced the number of deaths from bleeding (9.3% vs 3.4%,P〈0.05), but not those from liver failure following variceal hemorrhag. Prophylactic EIS is advantageous in the treatment of esophageal varices, i.e. it may prevent deaths fromliver failure attributed to variceal hemorrhages. The present study shows that preliminary prevention of variceal hemorrhage provides favorable hemostatic efficacy in patients with risky varices.

    Notes: Abstract: We investigated whether extravariceal collateral pattern contributed to the development of portal-hypertensive gastropathy (PHG) before and after sclerotherapy. Ninety-nine patients with cirrhosis and large esophageal varices were examined in this retrospective study. They were divided into four groups according to transhepatic portographic findings: group A (with neither paraesophageal veins nor gastrorenal shunt; n = 46), group B (with paraesophageal veins; n = 27), group C (with gastrorenal shunt; n = 14), and group D (with paraesophageal veins and gastrorenal shunt; n = 12). To assess PHG, endoscopic examinations were carried out before and 1 week and 1 month after sclerotherapy. The severity of PHG was classified according to a modified McCormack's classification and scored as: absence, 0; mild, 1; severe, 2. There were no significant differences in age, sex, cause of cirrhosis, severity of liver dysfunction, and extent of esophageal varices in the four groups. The PHG score before sclerotherapy was significantly higher in group A than in either group C (P 〈 0.05) or group D patients (P 〈 0.05). The calculated, integrated incremental change in PHG score after sclerotherapy was significantly higher in group A than in group C (P 〈 0.01) and group D patients (P 〈 0.01). Although the integrated change in PHG score was lower in group B than in group A patients, the difference was not significant (P = 0.68). These results suggest that gastrorenal shunt, but not paraesophageal veins, may play a protective role in the development of PHG before and after sclerotherapy.

    Notes: Abstract: Endoscopic variceal ligation therapy (EVL) seems to be a more effective and safer method than endoscopic injection variceal sclerotherapy (EVS) for treating bleeding esophageal varices. However, EVL may entail a higher recurrence rate than EVS. The aim of this study was to examine whether EVL combined with low-dose EVS reduced the recurrence rate compared to treatment with EVL alone and reduced the complication rate compared to treatment with EVS alone. In this prospective study, 59 patients with cirrhosis and high-risk (F2 or F3, red color sign ++ or +++) esophageal varices were enrolled. They were randomly assigned to an EVS group (n = 18), an EVL group (n = 20), and a combination EVL plus low-dose EVS group (n = 21). After the eradication of varices, follow-up endoscopic examinations were carried out for 24 months to determine the recurrence of varices. Complications, e.g., severe dysphagia, fever, renal dysfunction and pleuritis were also evaluated. The recurrence-free rate was significantly lower in the EVL group (60% at 24 months) than in either the EVS group (90%, P 〈 0.05) or the combination group (88%, P 〈 0.05). However, no significant difference was found between the EVS group and the combination group. The complication rate was significantly higher in the EVS group (50%) than in either the EVL group (5%, P 〈 0.01) or the combination group (10%, P 〈 0.01). The combination therapy seems to be useful to improve the benefits achieved with EVL alone and to reduce the harmful effects induced by EVS alone. EVL plus low-volume EVS is advisable in the treatment of high-risk esophageal varices.

    Notes: Abstract: The aim of this study was to compare postprandial hemodynamic changes observed during assumption of the recumbent posture and upright posture in patients with cirrhosis and portal hypertension. Eleven patients with cirrhosis and portal hypertension were studied. Echo-Doppler examinations were performed to measure flow volume in the portal vein (PV), superior mesenteric artery (SMA), and splenic artery (SA) in the fasting condition. Collateral blood flow was indirectly calculated by determining the difference between the sum of SMA, SA, and PV blood flows. After these measurements were done, each patient received a standardized liquid meal and was then randomly assigned to either maintain supine or upright posture, in a crossover design, on 2 different days (recumbent day and upright day). On each study day, the above-mentioned measurements were repeated 30 min and 60 min after the meal. PV blood flow increased significantly after the meal on the recumbent day (P 〈 0.01) but not on the upright day (P = 0.78). Although there were significant postprandial increases in SMA blood flow on both study days (P 〈 0.01, P 〈 0.01), the effect was less pronounced on the upright day than on the recumbent day (P 〈 0.01). Postprandial SA blood flow showed no change on the recumbent day (P = 0.64), but decreased significantly on the upright day (P 〈 0.01). The calculated postprandial collateral blood flow increased significantly on the recumbent day (P 〈 0.05), but showed no change on the upright day (P = 0.53). These results suggest that the upright posture blunts postprandial splanchnic hyperemia in patients with cirrhosis and portal hypertension.

    Notes: Abstract: Polyarteritis nodosa is a necrotizing angitis that predominantly affects small and medium-sized arteries. The prognosis of untreated polyarteritis nodosa is very poor. Since symptoms are diverse and no serologic test is specific for polyarteritis nodosa, the diagnosis is difficult and often delayed. We describe a patient with polyarteritis nodosa who had gastrointestinal involvement with multiple aneurysms of the inferior mesenteric artery; only abdominal angiography provided a conclusive diagnosis. Alleviation of symptoms and regression of aneurysms were observed after combination therapy of an immunosuppressive agent, cyclophosphamide, and prednisolone. We emphasize the importance of early diagnosis by angiography and aggressive therapy in patients in whom physical signs indicating definite polyarteritis nodosa are not present.

    Notes: Abstract We studied 30 patients with cirrhosis to determine the effect of nitroglycerin on portal and gastric mucosal hemodynamics. Systemic hemodynamics, portal venous pressure (PVP), the hemoglobin index (IHB), and the oxygen saturation index (ISO2) of the gastric mucosa were measured before and after a continuous infusion of nitroglycerin. The patients were divided into two groups according to the presence or absence of major portal-systemic collateral routes on portograms. Nitroglycerin caused a reduction in PVP in all patients. Although there was no significant difference in systemic hemodynamic changes between the two groups, the reduction in PVP in patients with major portal-systemic collaterals was significantly higher than in those without major collaterals. A nitroglycerin infusion, at a dose of 1.0μg/kg per min for 10 min, produced a reduction in both IHB (−16%,P〈0.001) and ISO2 (−13%,P〈0.001) in the gastric mucosa, indicating gastric mucosal ischemia secondary to splanchnic vasoconstriction. These findings suggest that the continuous infusion of nitroglycerin reduces PVP in cirrhotic patients, particularly in those with major portal-systemic collaterals, and reduces the congestion of the gastric mucosa in patients with portal hypertension.

    Notes: Abstract Gastric mucosal hyperemia associated with elevated serum gastrin level has been suggested in cirrhotic patients with portal hypertensive gastropathy (PHG). Clinical evidence has shown that these patients may benefit from propranolol administration. The aim of this study was to investigate effect of propranolol on gastric mucosal perfusion and serum gastrin level in cirrhotic patients with portal hypertensive gastropathy. Gastric mucosal perfusion was assessed by laser Doppler flowmetry. Measurements were performed under basal conditions and after observer-blind administration of propranolol (30–60 mg/day,N=9) or placebo (N=9) for seven days. Placebo had no effect on either gastric mucosal perfusion or serum gastrin level. In contrast, propranolol administration significantly decreased both antrum gastric mucosal perfusion (from 0.88±0.28 to 0.73±0.26 V,P〈0.05) and corpus gastric mucosal perfusion (from 0.94±0.35 to 0.78±0.25 V,P〈0.05). However, this drug had no effect on serum gastrin level. We conclude that chronic propranolol administration in cirrhotic patients with portal hypertensive gastropathy may reduce gastric mucosal perfusion without changing serum gastrin level.
