Portal hemodynamics in patients with gastric varices. A study in 230 patients with esophageal and/or gastric varices using portal vein catheterization.

The hemodynamic features of gastric varices are not well documented. The purpose of this study was to investigate the nature of hepatofugal collateral veins, their origins, the direction of blood flow in the major veins and collateral veins, and portal venous pressure. To this end, 230 patients, mostly cirrhotic, who had esophageal or gastric varices, or both, demonstrated by endoscopy were investigated by portal vein catheterization. The findings were correlated with endoscopically assessed degrees of varices. Gastric varices were seen in 57% of the patients with varices due to portal hypertension. In most of the patients with advanced gastric varices, esophageal varices were minimal or absent. When patients with gastric varices were compared with those having predominantly esophageal varices, it was found that advanced gastric varices were more frequently supplied by the short and posterior gastric veins, they were almost always associated with large gastrorenal shunts, and portal venous pressure in patients with large gastric varices was lower. Chronic portal systemic encephalopathy was more common in patients with large gastric varices due to hepatofugal flow of superior mesenteric venous blood in the splenic vein than in patients with predominantly esophageal varices. Thus, the hemodynamics in patients with large gastric varices are distinctly different from those in patients with mainly esophageal varices, and such differences seem to account for the differing incidence of chronic encephalopathy and variceal bleeding.

Esophageal variceal ligation for acute variceal bleeding: results of three years' follow-up.

BACKGROUND/AIMS: Endoscopic variceal ligation is widely accepted as the optimum endoscopic treatment for esophageal variceal hemorrhage. However, the rebleeding course and long-term outcome of patients with esophageal variceal hemorrhage after ligation have been poorly defined. Therefore, we conducted a long-term follow-up study to delineate the outcome of ligation. METHODS: Twenty-one liver cirrhotic patients with endoscopically proven esophageal variceal hemorrhage were treated by endoscopic variceal ligation. These patients received regular follow-up and detailed clinical assessment of at least 24 months. RESULTS: Twenty-one eligible patients were followed up for a mean of 44.45 months (range 33.5-64 months). The mean number of sessions required to obtain eradication was 3.57+/-1.99 (range 1-8). Esophageal varices could be obliterated within 11.57+/-6.8 weeks (range 3-30). The percentage of variceal recurrence during follow-up was 57.14% (12/21) after endoscopic variceal ligation. Recurrence were observed in a mean of 34 months (median 29 months). Rebleeding from esophageal varices appeared in four patients (19.04%). The appearance rates of portal hypertensive gastropathy and fundal gastric varices after varice obliteration were found to be 45.45% (5/11) and 25% (3/12), respectively. CONCLUSIONS: Based on the results of long-term follow-up of endoscopic variceal ligation, although the percentage of variceal recurrence was high, endoscopic ligation achieved variceal obliteration faster and in fewer treatment sessions. Furthermore, endoscopic variceal ligation had a lower rate of rebleeding and of development of fundal gastric varices, but high portal hypertensive gastropathy.

Variceal recurrence, rebleeding, and survival after endoscopic injection sclerotherapy in 287 alcoholic cirrhotic patients with bleeding esophageal varices.

OBJECTIVE: This study tested the validity of the hypothesis that eradication of esophageal varices by repeated injection sclerotherapy would reduce recurrent variceal bleeding and death from bleeding varices in a high-risk cohort of alcoholic patients with cirrhosis. SUMMARY BACKGROUND DATA: Although banding of esophageal varices is now regarded as the most effective method of endoscopic intervention, injection sclerotherapy is still widely used to control acute esophageal variceal bleeding as well as to eradicate varices to prevent recurrent bleeding. This large single-center prospective study provides data on the natural history of alcoholic cirrhotic patients with bleeding varices who underwent injection sclerotherapy. METHODS: Between 1984 and 2001, 287 alcoholic cirrhotic patients (225 men, 62 women; mean age, 51.9 years; range, 24-87 years; Child-Pugh grades A, 39; B, 116; C, 132) underwent a total of 2565 upper gastrointestinal endoscopic sessions, which included 353 emergency and 1015 elective variceal injection treatments. Variceal rebleeding, eradication, recurrence, and survival were recorded. RESULTS: Before eradication of varices was achieved, 104 (36.2%) of the 287 patients had a total of 170 further bleeding episodes after the first endoscopic intervention during the index hospital admission. Rebleeding was markedly reduced after eradication of varices. In 147 (80.7%) of 182 patients who survived more than 3 months, varices were eradicated after a mean of 5 injection sessions and remained eradicated in 69 patients (mean follow-up, 34.6 months; range, 1-174 months). Varices recurred in 78 patients and rebled in 45 of these patients. Median follow-up was 32.3 months (mean, 42.1 months; range, 3-198.9 months). Cumulative overall survival by life-table analysis was 67%, 42%, and 26% at 1, 3, and 5 years, respectively. A total of 201 (70%) patients died during follow-up. Liver failure was the most common cause of death. CONCLUSION: Repeated sclerotherapy eradicates esophageal varices in most alcoholic cirrhotic patients with a reduction in rebleeding. Despite control of variceal bleeding, survival at 5 years was only 26% because of death due to liver failure in most patients.

Effect of esophageal variceal band ligation on hemorrhoids, anorectal varices, and portal hypertensive colopathy.

BACKGROUND AND STUDY AIMS: Although it is known that obliteration of esophageal varices following endoscopic variceal band ligation results in an increase in the incidence of portal hypertensive gastropathy, the effect of variceal ligation on hemorrhoids, anorectal/colonic varices and portal hypertensive colopathy is not known. The aim of this study was to investigate the effect of endoscopic variceal band ligation on hemorrhoids, anorectal/colonic varices and portal hypertensive colopathy. PATIENTS AND METHODS: A total of 60 consecutive patients with cirrhosis of the liver and portal hypertension were prospectively studied. Upper gastrointestinal endoscopy and full-length colonoscopy were carried out before the patients underwent endoscopic variceal band ligation for esophageal varices and after obliteration of the varices following band ligation. RESULTS: Obliteration of esophageal varices by endoscopic variceal band ligation did not affect the incidence of hemorrhoids (37 % before and after), anorectal varices (40 % before and after), and portal hypertensive colopathy (57 % before and after). CONCLUSIONS: It is concluded that esophageal variceal band ligation does not affect the incidence of hemorrhoids, anorectal varices or portal hypertensive colopathy in patients with cirrhosis of the liver.

Clinical significance of variceal hemorrhage in recent years in patients with liver cirrhosis and esophageal varices.

BACKGROUND AND AIMS: Recent progress in the treatment of variceal bleeding might have reduced the impact of variceal bleeding on survival in patients with esophageal varices. We conducted a retrospective cohort study in an attempt to re-evaluate the clinical significance of variceal bleeding. METHODS: A cohort of 304 patients with liver cirrhosis and esophageal varices, who had no previous history of variceal bleeding and no prophylactic therapy, was studied. RESULTS: During a median follow-up period of 32 months, 55 patients (18%) bled from varices and 111 (37%) died. Variceal hemorrhages accounted for 15% of total deaths. The mortality of first variceal bleeding was 25% in the whole group, but was remarkably different depending on liver function at the time of bleeding (0% in grade Child A vs 55% in grade C; P < 0.05). Among the survivors of first bleeding, 30% experienced rebleeding. Form of varix, red color sign and heavy drinking were the independent risk factors for first variceal bleeding. Multivariate analysis revealed that variceal bleeding still had a significant (P < 0.001) impact on death in the whole cohort, when other independent prognostic factors such as age, ascites, encephalopathy, platelet count, serum albumin level and hepatocellular carcinoma were adjusted. Furthermore, in subgroup analyses, variceal bleeding was more strongly (P < 0.001) linked to death in patients with alcoholic cirrhosis than in those with non-alcoholic cirrhosis, and showed a significant association with survival only for the patients in Child grade B. CONCLUSIONS: Variceal bleeding has various prognostic impacts depending on the etiology of cirrhosis or on the degree of liver dysfunction, and this needs to be taken into account in the prophylaxis against first variceal bleeding.

A new method of endoscopic variceal ligation-injection sclerotherapy (EVLIS) for gastric varices.

OBJECTIVES: For esophageal varices, endoscopic variceal sclerotherapy and band ligation have been effectively and frequently used, but these methods were not effective for gastric varices. In gastric varices, because of rich networks of feeding vessels and shunts that may exist in many cases, an effective therapeutic level of sclerosant is difficult to be maintained. Accordingly, we propose a new method called "Endoscopic Variceal Ligation-Injection Sclerotherapy (abbreviated EVLIS)" for gastiric varices, with focus on maintenance of the effective therapeutic level of a sclerosant by partially blocking the blood flow of gastric varices using the band ligation method. The study was undertaken prospectively to evaluate the efficacy and safety of EVLIS for the treatment of gastric varices. METHODS: EVLIS was performed in a group of 32 patients with gastric varices. Active bleeding varices were 11 and non-bleeding 21. Five cases were grade A, 12 grade B, and 14 grade C of Child's classification. Nine cases were type 1, 22 type 2, and 1 was type 3 of Hosking-Johnson's classification. RESULTS: The results of EVLIS were excellent, active bleeding of gastric varices in the 11 cases were successfully controlled and all the gastric varices of 32 cases including those bleeding varices were completely eradicated. The bleeding status, the Child's grade and the Hosking-Johnson's class do not appear to correlate in any way with the efficacy of this technique. No perforation or re-bleeding was observed in any of the patients until the mean 10.6 months of the follow-up period. CONCLUSIONS: EVLIS should be considered as an effective and safe treatment for gastric varices.

Sequential changes of esophageal motility after endoscopic injection sclerotherapy or variceal ligation for esophageal variceal bleeding: a scintigraphic study.

OBJECTIVE: Endoscopic injection sclerotherapy and variceal ligation are two popular endoscopic methods used to treat esophageal variceal hemorrhage. These two methods have not been compared with regard to esophageal dysfunction after treatment. This is a prospective investigation of esophageal dysmotility after endoscopic injection sclerotherapy and variceal ligation. METHODS: Sequential changes of esophageal motility after endoscopic injection sclerotherapy (n = 25) and variceal ligation (n = 25) were investigated in 50 cirrhotic patients with recent variceal bleeding. Another 22 cirrhotics without esophageal varices were included as controls. Radionuclide esophageal transit tests were performed before initial endoscopic treatment, and 1 and 3 months after variceal eradication. RESULTS: The baseline esophageal transit time was longer in both the sclerotherapy (n = 25, 7.8 +/- 1.4 s) and ligation groups (n = 25, 8.2 +/- 1.8 s) than in controls (n = 22, 6.7 +/- 0.7 s, p < 0.005). The transit time was longer in patients with large varices than in those with small varices (8.3 +/- 1.7 vs. 7.2 +/- 0.7 s, p < 0.05). In the sclerotherapy group, the transit time was prolonged 1 month after variceal eradication, compared with its pretreatment state (n = 20, 7.6 +/- 1.5 vs. 10.0 +/- 2.2 s, p < 0.0001) but was shortened at 3 months compared with 1 month after variceal eradication (n = 12, 10.7 +/- 1.5 vs. 8.6 +/- 2.2 s, p < 0.05). Multiple regression analysis showed that the number of treatment sessions required to eradicate varices was the only significant factor associated with prolonged transit time (p < 0.05). In the ligation group, the transit time changed little at 1 month or 3 months after variceal eradication. CONCLUSIONS: Impairment of esophageal motility can be significant with endoscopic injection sclerotherapy but is reversible. However, endoscopic variceal ligation exerts no significant impact on esophageal motility.

Clinical trial of prophylactic endoscopic variceal ligation for esophageal varices.

Endoscopic variceal ligation is an effective therapy for variceal bleeding, and use of the method has recently been increasing. We evaluated the clinical usefulness of prophylactic endoscopic variceal ligation. Twenty-two patients with enlarged, tortuous varices and "red color signs" were selected. These patients were treated with ligation therapy alone and the varices were eradicated, i.e., reduced to small, straight varices without red color signs. Ligation therapy was withdrawn if the general condition of the patient worsened or if the varices could not be removed by suction. Follow-up endoscopy was performed every 4 months, and another ligation was performed if there were recurrent varices or variceal bleeding. The total reduction rate was 86.4%, and eradication required two sessions of therapy and 30 days of hospitalization on average. Complications included esophageal injury in 1 patient and treatment-induced bleeding in 1 patient; both complications were easily controlled. No variceal bleeding occurred after the eradication. There was no mortality due to gastrointestinal bleeding during the median follow-up period of 346 days. Prophylactic endoscopic variceal ligation made it possible to prevent fatal variceal bleeding with a minimum risk of complications, suggesting that this could be an alternative method for the prevention of first-time variceal bleeding.

Hemodynamic assessment of the left gastric vein in patients with esophageal varices with color Doppler EUS: factors affecting development of esophageal varices.

BACKGROUND: An understanding of the development of esophageal varices is important in the evaluation of risk of variceal hemorrhage. To clarify factors affecting the development of esophageal varices, the morphology and hemodynamics of the left gastric vein were analyzed with color Doppler EUS. METHODS: Sixty-seven patients with esophageal varices underwent color Doppler EUS. Seventeen had small varices (F1), 32 had medium varices (F2), and 18 had large varices (F3). RESULTS: Hepatofugal blood flow velocity in the left gastric vein trunk increased as the size of the varices increased (p < 0.0001), whereas the diameter did not increase. The left gastric vein bifurcates into anterior and posterior branches. As the size of the varices enlarged, the branch pattern was more likely to be anterior branch dominant (p = 0.041). There was no significant difference between the 3 size groups of esophageal varices with respect to the size of the paraesophageal collaterals. The detection rate and diameter of the perforating vein increased as the size of the varices increased (p = 0.032 and 0.012, respectively). CONCLUSION: Blood flow velocity in the left gastric vein trunk, branches, and perforating veins may regulate blood flow supplying the esophageal varices and contribute to their development. These findings are important to understanding the pathogenesis of esophageal varices.

[Endoscopic ligation of esophageal varices: prevention of hemorrhagic recurrences caused by rupture of esophageal varices. Results in 45 patients].

OBJECTIVES: The aim of this study was to assess the morbidity and efficacy of endoscopic variceal ligation for the prophylaxis of rebleeding from oesophageal varices. METHODS: Forty-five patients with cirrhosis (Child's class: A: 18, B: 16, C: 11) and recent (< 48 h) variceal bleeding were included. Eleven of the patients were included after failure of sclerotherapy. All patients were treated by endoscopic ligation until the complete eradication of oesophageal varices. The mean follow-up was 8.7 +/- 6.8 months. RESULTS: Oesophageal varices were eradicated in 40 patients (89%) after an average of 2 sessions (range: 1-5). In a subset of 11 patients treated after failure of sclerotherapy, 8 (73%) had complete eradication of oesophageal varices. Six of the 45 patients (13%) had recurrence of haemorrhage, due to post-ligation ulcerations in 5 cases and to rupture of oesophageal varices in one case. The rate of complications was 7%. Of the 40 patients whose oesophageal varices were eradicated, 7 (17%) were lost for follow up, and another treatment was performed in 4 (10%): liver transplantation in 2, and transjugular intrahepatic portosystemic shunt in 2. Recurrence of oesophageal varices after eradication was observed in 3 (10%) of the remaining 29 patients after a follow-up of 8.9 +/- 12.9 months. Of these 3 patients, only one (3%) presented with recurrence of haemorrhage due to ruptured oesophageal varices. Three patients (7%) died before eradication of oesophageal varices from causes unrelated to the technique. CONCLUSION: This study confirms that endoscopic ligation is effective for eradication of oesophageal varices, with a low morbidity. This technique appears to be a method of choice in the prophylaxis of rebleeding from oesophageal varices, especially when sclerotherapy is ineffective.

Noninvasive variceal pressure measurement may be useful for predicting effect of sclerotherapy for esophageal varices.

This study assessed the relationship between variceal pressure and morphological findings and hemodynamics of esophageal varices as well as the effect of sclerotherapy. Esophageal variceal pressure was measured in 40 patients with portal hypertension, using a noninvasive method. Esophageal variceal pressures were significantly higher in moderate or large varices than they were in small varices. Variceal pressures were significantly higher in patients with red color signs on the varices than in those without. According to the percutaneous transhepatic portography, the structure of the esophageal varices was classified into two types: the bar type and the palisading type. The maximum variceal pressure was significantly higher in the bar type than in the palisading type. In patients who underwent more than five sessions of sclerotherapy, the variceal pressure was significantly higher than in those receiving less than four sessions. These results suggest that variceal pressure may well reflect the vascular pattern and be useful for predicting the effect of sclerotherapy.

Management of esophageal varices in children by endoscopic variceal ligation.

Endoscopic variceal sclerotherapy (EVS) has been considered the mainstay of therapy for bleeding esophageal varices in adults. However, recent data have shown that endoscopic variceal ligation (EVL) is just as efficacious and has fewer complications than EVS. Although there are many reports concerning EVL in adults, only a few studies have been done in children. This report describes experience with EVL in 22 children with esophageal variceal hemorrhage. Eighty-seven EVL procedures were performed during a 9-year period in 22 children. The causes of portal hypertension were biliary atresia (10), portal vein thrombosis (8), chronic active hepatitis (1), cirrhosis secondary to cystic fibrosis (2), and primary sclerosing cholangitis (1). The age range at the onset of variceal bleeding was 8 months to 19 years. Twelve patients had EVS before EVL treatment was begun. Distal esophageal varices (one to four per session) were mechanically ligated using an elastic band ligature device attached to a flexible endoscope. The aim of therapy was obliteration of distal esophageal varices by EVL, every 2 to 4 weeks, until eradication. Subsequent EVL was dictated by the status of the varices. Outcome was assessed with respect to survival, rebleeding, status of varices, and complications. The patients underwent a mean of four sessions of EVL (range, one to eight). Four patients subsequently underwent liver transplantation. Of the 18 patients remaining (average follow-up period, 5.3 years), 12 had their varices eradicated (average of four EVL sessions), four are still in treatment, one has not been evaluated in the past 4 years, and one died of liver failure. Complications included bleeding between sessions (6 patients), cervical esophageal perforation (1 patient), and transient fever (2 patients). No child has experienced symptoms of esophageal stenosis or gastroesophageal reflux. Two patients died of liver disease, unrelated to bleeding from portal hypertension. EVL is effective in controlling variceal hemorrhage in children with portal hypertension, regardless of etiology. The complication rate is low, and EVL is an acceptable and perhaps preferable alternative to EVS in children with esophageal varices.

Role of percutaneous transhepatic obliteration of varices in the management of hemorrhage from gastroesophageal varices.

One hundred and forty-one attempts at percutaneous transhepatic variceal obliteration were made in 116 patients with portal hypertension complicated by variceal hemorrhage. Varices were successfully obliterated in 80% of procedures and included 37 patients with continuous, acute variceal hemorrhage. Hemorrhage ceased immediately in these patients. Sixty-five percent of patients rebled a mean of 4.6 mo after successful transhepatic variceal obliteration. A randomized controlled trial against conventional medical therapy (29 treatment, 25 control) failed to show a significant reduction in death rate after transhepatic sclerotherapy, although the onset of further variceal hemorrhage was delayed. Follow-up portography in 50 patients demonstrated new vessel formation in 38 patients and recanalization of previously occluded varices in 5 patients. Complications arose in 29 of 141 procedures. There was one death but all the other complications responded to conservative management. Transhepatic variceal obliteration is an excellent, safe emergency treatment for variceal hemorrhage, especially in patients with decompensated liver disease. A high incidence of rebleeding is a long-term disadvantage and means that transhepatic variceal obliteration should not be used for the prophylaxis of variceal hemorrhage. Successful emergency treatment of variceal hemorrhage should be followed by elective portal decompression in suitable patients.

Variceal pressure is a factor predicting the risk of a first variceal bleeding: a prospective cohort study in cirrhotic patients.

Predictive criteria for a first variceal hemorrhage lack substantial accuracy. Cross-sectional studies suggest a close relationship between variceal pressure (VP) and the occurrence of variceal bleeding. In the present prospective cohort study, the significance of VP measurement for prediction of a first variceal bleed was assessed. Eighty-seven patients with cirrhosis and large esophageal varices who had never developed variceal bleeding were followed for 12 months. The endpoint of the study was the presentation or not of a variceal hemorrhage. Thirty-four patients (39%) were in Child's class A, 37 in class B (43%), and 16 in class C (18%). The median interval between endoscopic diagnosis of varices and the beginning of the study was 15 months. Twenty-eight patients (32%) developed a variceal hemorrhage with a bleeding-related mortality of 18% (n=5). The 1-year mortality overall was 16% (n=14). Variables predictive of a first bleed identified by Cox proportional hazards regression model were: the level of VP, the North Italian Endoscopic Club (NIEC) score, and the interval between the diagnosis of varices and the start of the study. By adding VP to NIEC, a significant gain in prognostic accuracy was obtained (P = .003). In conclusion, the present study provides evidence that the level of VP is a major predictive factor for variceal hemorrhage, and that it provides further prognostic information in addition to the NIEC index.

Variceal ligation compared with endoscopic sclerotherapy for variceal hemorrhage: prospective randomized trial.

BACKGROUND: To evaluate the safety and efficiency of variceal ligation compared with endoscopic sclerotherapy, 88 patients with cirrhosis with recent variceal bleeding were randomized to undergo either treatment. METHODS: Sclerotherapy was performed using ethanolamine and polidocanol injection at 1, 2, and 3 weeks and every 3 weeks thereafter. The Stiegmann-Goff device was used for variceal ligation at the same intervals. RESULTS: The rate of variceal eradication was the same for both groups, but eradication was accomplished sooner in patients undergoing variceal ligation (5.3+/-1.6 vs. 6.6+/-2.4 endoscopic sessions, p < 0.05) and with fewer complications (19 vs. 6, p < 0.005). The rate of recurrent bleeding was lower in patients treated by ligation (31% vs. 50%, p < 0.05). After eradication, variceal recurrence was more frequent in patients treated by variceal ligation at 1 and 3 years (47% and 92% vs. 23% and 55%, p < 0.01). Portal hypertensive gastropathy was significantly worse in the patients who had variceal ligation (17 patients vs. 6, p < 0.01). Survival and treatment failure were similar in both groups. CONCLUSIONS: Variceal ligation was superior to sclerotherapy in terms of the rate of recurrent bleeding and the occurrence of complications but worse with respect to recurrence of varices and the evolution of portal hypertensive gastropathy. Long-term follow-up studies are required to find out whether there are deleterious effects of variceal ligation.

Endoscopic injection sclerotherapy vs. endoscopic variceal ligation in arresting acute variceal bleeding for patients with advanced hepatocellular carcinoma.

Patients with advanced hepatocellular carcinoma and acute esophageal variceal bleeding have a very poor prognosis. To compare the efficacy and complications of sclerotherapy and banding ligation, patients with acute esophageal variceal bleeding and concomitant hepatocellular carcinoma were randomly allocated to receive either sclerotherapy (endoscopic injection sclerotherapy group, 27 patients) or banding ligation (endoscopic variceal ligation group, 30 patients). All patients received treatment within 24 h of index bleeding. Initial control of bleeding was achieved in 41% of the endoscopic injection sclerotherapy group and 87% of the endoscopic variceal ligation group (p < 0.001). The re-bleeding rates were 73% and 42%, respectively (p < 0.05). The amount of blood transfused during the week after treatment was significantly higher in the endoscopic injection sclerotherapy than in the endoscopic variceal ligation group (3.9 +/- 1.5 vs. 1.5 +/- 0.8 units, respectively) (p < 0.01). Major complications were more often encountered in the endoscopic injection sclerotherapy group (22%) than in the endoscopic variceal ligation group (3%) (p < 0.05). Twenty-three patients in the endoscopic injection sclerotherapy group and 25 patients in the endoscopic variceal ligation group have so far died. The mean survival was 25 +/- 16 days in the endoscopic injection sclerotherapy group and 49 +/- 14 days in the endoscopic variceal ligation group (p < 0.05). Variceal bleeding was the main cause of mortality in the endoscopic injection sclerotherapy group (70%), whereas in the endoscopic variceal ligation group, hepatic failure (48%), rather than variceal bleeding (28%), was the major cause.(ABSTRACT TRUNCATED AT 250 WORDS)

Improvement of collateral vessels in the vicinity of gastric cardia after endoscopic variceal ligation therapy for esophageal varices.

BACKGROUND & AIMS: Endoscopic variceal ligation (EVL) therapy has been performed widely to treat or prevent variceal bleeding. We sought to examine the influence of EVL for esophageal varices on collateral vessels in the vicinity of gastric cardia. METHODS: In 42 patients with esophagogastric varices, conventional endoscopy and endoscopic ultrasonography with a 20-MHz probe (CUP-EUS) were performed before and at every 3 months after EVL for esophageal varices. By using conventional endoscopy, cardial variceal sizes were divided into 3 grades: F0, F1, and F2. The sizes of submucosal, perforating, and paracardial vessels at the cardia also were classified into 3 grades according to CUP-EUS findings. RESULTS: Conventional endoscopy showed cardial varices in 33 (79%) patients before and 23 (55%) patients at 3 months after the treatment (P < 0.05). CUP EUS showed that 29 (69%) patients had severe grade cardial submucosal vessels before EVL, but only 13 (31%) patients did after the treatment (P < 0.01). Nineteen (45%) patients had severe grade cardial perforating vessels before EVL, but only 4 (10%) patients did after the treatment (P < 0.001). Furthermore, patients with severe grade residual submucosal or perforating vessels at the cardia had shorter recurrence-free times of esophageal varices (P < 0.01, 0.05, respectively). CONCLUSIONS: Collateral vessels in the vicinity of gastric cardia were improved significantly after EVL, indicating that esophageal varices can be treated by EVL even though they connect with cardial varices. Furthermore, eradication of such collateral vessels by EVL may lead to longer recurrence-free status of esophageal varices.

Comparison of endoscopic variceal ligation and nadolol plus isosorbide-5-mononitrate in the prevention of first variceal bleeding in cirrhotic patients.

BACKGROUND: Both drug therapy and banding ligation are widely used in the prevention of first variceal bleeding. This study compared the efficacy and safety of band ligation vs. combination of beta-blocker and nitrate for the prevention of first bleeding in patients with cirrhosis and high-risk esophageal varices. METHODS: A total of 61 patients with cirrhosis with moderate or severe esophageal varices associated with red color signs but without history of variceal bleeding were randomized to band ligation (30 patients) or treatment with nadolol plus isosorbide-5-mononitrate (ISMN) (31 patients). In the ligation group, multiband ligator with 4 elastic bands was applied during each session. Ligation was repeated at intervals of 4 weeks until variceal obliteration was achieved. In the combination group, the dose of nadolol was sufficient to reduce the pulse rate by 25%. ISMN 1 tablet 20 mg qd or bid was administered. RESULTS: Both groups were similar in baseline characteristics. In the ligation group, variceal obliteration was achieved in 24 patients (80%), at a mean of 3.2 +/- 0.9 ligation sessions and 11.7 +/- 3.2 elastic bands. In the combination group, the mean daily doses of nadolol and ISMN administered were 40 +/- 14 mg and 40 +/- 12 mg, respectively. During a median follow-up of approximately 23 months, 5 patients (17%) in the ligation group and 8 patients (26%) in the combination group had upper-gastrointestinal bleeding (p = 0.53). Esophageal variceal bleeding occurred in 3 patients (10%) in the ligation group and 6 (19%) in the combination group (p = 0.42). By multivariate Cox analysis, presence of ascites was the only factor predictive of variceal bleeding. Minor complications were noted in 5 patients (17%) in the ligation group and 3 (10%) in the combination group (p = 0.47). Eight patients in the ligation group and 6 in the combination group died (p = 0.49). One (3%) patient in the ligation group and 3 (10%) in the combination group died of uncontrollable variceal bleeding. CONCLUSION: Our preliminary results suggest that endoscopic variceal ligation is similar to the combination of nadolol plus ISMN with regard to effectiveness and safety in the prevention of first variceal bleeding in patients with cirrhosis.
