Administration of nonselective beta-blockers in prophylaxis of first variceal bleeding is not suitable for all patients. Thus, we evaluated endoscopic variceal band ligation (EVBL) in primary prevention of bleeding in patients with cirrhosis and large esophageal varices. A total of 73 consecutive patients with liver cirrhosis and large esophageal varices without a history of gastrointestinal bleeding were randomized to receive either EVBL or propranolol and were followed for up to 18 months. Forty patients underwent EVBL and 33 patients received propranolol. Variceal bleeding occurred in 2 patients in the EVBL (5%) and in 2 patients in the propranolol group (6%, NS). The 18 month actuarial risk for first variceal bleed was 5% in the EVBL (95% CI, 0-12%) and 20% in the propranolol group (95% CI, 0-49%, NS). The actuarial probability of death at 18 months of follow-up was 5% (95% CI, 0-11%) in the EVBL group and 7% (95% CI, 0-17%, NS) in the propranolol arm. In conclusion, EVBL was an effective and safe alternative to propranolol in primary prophylaxis of bleeding in patients with large esophageal varices. 相似文献

BACKGROUND: The value of band ligation for prevention of the first episode of variceal bleeding has not been fully evaluated. This study compared the efficacy and safety of band ligation vs. treatment with a beta-blocker for the prophylactic prevention of first bleeding in patients with cirrhosis and high-risk esophageal varices. METHODS: A total of 100 patients with cirrhosis and endoscopically determined high-risk esophageal varices but no history of bleeding were randomized to band ligation (50 patients) or treatment with nadolol (50 patients). In the ligation group, two to 4 elastic bands were deployed during each session. Ligation was repeated at intervals of 3 to 4 weeks until variceal obliteration was achieved. In the nadolol group, the dose of the drug, administered once daily, was sufficient to reduce the pulse rate by 25%. RESULTS: In the ligation group, variceal obliteration was achieved in 41 patients (82%), at a mean of 2.7 (1.1) ligation sessions. In the nadolol group, the mean daily dose of nadolol administered was 60 (20) mg. During follow-up (median approximately 22 months), 10 patients (20%) in the ligation group and 16 (32%) in the nadolol group had upper-GI bleeding (p=0.23). Esophageal variceal bleeding occurred in 5 patients (10%) in the ligation group and 9 (18%) in the nadolol group (p=0.31). By multivariate Cox analysis, Child-Pugh class was the only factor predictive of variceal bleeding. Minor complications were noted in 9 patients (18%) in the ligation group and 4 (8%) in the nadolol group (p=0.35). No serious complication was encountered. Twelve patients in the ligation group and 11 in the nadolol group died (p=0.62). One patient in the ligation group and 3 in the nadolol group died from uncontrollable variceal hemorrhage. CONCLUSIONS: Variceal ligation is as effective and as safe as treatment with nadolol for prevention of first variceal bleeding in patients with cirrhosis. 相似文献

BACKGROUND AND AIM: To compare the efficacy and safety of endoscopic variceal ligation (EVL) with propranolol in prophylaxis on the rate of first esophageal variceal bleeding in patients with cirrhosis. METHODS: A prospective, randomized trial was conducted in 100 cirrhotic patients with no history of previous upper gastrointestinal bleeding and with esophageal varices endoscopically judged to be at high risk of hemorrhage. The end-points of the study were bleeding and death. RESULTS: Life-table curves showed that prophylactic EVL and propranolol were similarly effective for primary prophylaxis of variceal bleeding (11/50 [22%]vs 12/50 [24%]; P = 0.68) and overall mortality (14/50 [28%]vs 12/50 [24%]; P = 0.49). The 2-year cumulative bleeding rate was 18% (9/50) in the EVL group and 16% (8/50) in the propranolol group. The 2-year cumulative mortality rate was 28% (14/50) in the EVL group and 24% (12/50) in the propranolol group. Comparison of Kaplan-Meier estimates of the time to death of both groups showed no significant difference in mortality in both groups (P = 0.86). Patients undergoing EVL had few treatment failures and died mainly of hepatic failure. In the propranolol group, the mean daily dosage of the drug was 68.2 +/- 32.8 mg, which was sufficient to reduce the pulse rate by 25%. 20% of patients withdrew from propranolol treatment due to adverse events. CONCLUSIONS: Prophylaxis EVL is as effective and as safe as treatment with propranolol in decreasing the incidence of first variceal bleeding and death in cirrhotic patients with high-risk esophageal varices. 相似文献

BACKGROUND: Prevention of variceal bleeding, a major cause of morbidity and mortality, is an important goal in the management of patients with portal hypertension (PHT). Although propranolol has been found useful in preventing the first episode of variceal bleeding (primary prophylaxis) in cirrhotic PHT, it has limitations which include side effects, contraindications, non-compliance and failure in some patients. Endoscopic variceal ligation (EVL) has not been used for primary prophylaxis. METHODS: Thirty cirrhotic patients with PHT, grade III to IV oesophageal varices, hepatic venous pressure gradient > or = 12 mmHg and no prior history of upper gastrointestinal bleeding were randomized to receive propranolol (to reduce their pulse rate by 25% from baseline, n = 15) and EVL (weekly to fortnightly until variceal eradication, n = 15). The two groups were comparable. All the patients in EVL group had variceal eradication during 3.8 +/- 2.2 sessions. RESULTS: There was no major complication or interval bleeding. During a follow-up period of 17.6 +/- 4.7 months, varices recurred in three, two of which bled (successfully treated by EVL). In contrast, during this period of follow up one patient in the propranolol group had variceal bleeding (P=NS). Side effects of propranolol included symptomatic bradycardia requiring reduction of dose in one of 15 patients. CONCLUSIONS: Although sample size in this study is small, it seems that EVL may be a good option for primary prophylaxis for variceal bleeding in patients with cirrhotic PHT; further studies on a larger number of patients and longer follow up are required. 相似文献

BACKGROUND AND AIMS: The role of propranolol in addition to EVL in the prevention of first variceal bleed has not been evaluated. This prospective randomized controlled trial compared endoscopic variceal ligation (EVL) with propranolol and EVL alone in the prevention of first variceal bleed among patients with high-risk varices. PATIENTS AND METHODS: One hundred and forty-four consecutive patients with high-risk varices were randomly allocated to EVL plus propranolol (Gr I, n = 72) or EVL alone (Gr II, n = 72). EVL was done at 2-wk interval till obliteration of varices. In Gr I, incremental dosage of propranolol (sufficient to reduce heart rate to 55 beats/min or 25% reduction from baseline) was administered and continued after obliteration of varices. The endpoints of the study were bleeding and death. RESULTS: The two groups of patients had comparable baseline characteristics; follow-up (Gr I: 13.1 +/- 11.5 months, Gr II: 11.2 +/- 9.9 months), number of cirrhotic and noncirrhotic portal hypertension patients [Gr I 64 (88.6%) and 8 (11.4%), Gr II 63 (87.5%) and 9 (12.5%)], and frequency of Child's A (15 vs 18), B (38 vs 35), and C (19 vs 19). The mean daily propranolol dose achieved in Gr I was 95.6 +/- 38.6 mg. Eleven patients had bleeds, 5 in Gr I and 6 in Gr II. All patients bled before the obliteration of varices, the actuarial probability of first bleed at 20 months was 7% in Gr I and 11% in Gr II (p= 0.72). Six patients died in the combination and 8 in EVL group. All deaths in Gr I were due to nonbleed-related causes, while in Gr II, 2 deaths were bleed related, the actuarial probability of death at 20 months was 8% and 15%, respectively (p= 0.37). The probability of bleed-related death was comparable (p= 0.15). At the end of follow-up, 4 patients in Gr I and 11 in Gr II had recurrence of varices (p= 0.03). Side effects on propranolol were seen in 22% patients, in 8% it had to be stopped. There were no serious complications of EVL. CONCLUSIONS: Both EVL plus propranolol and EVL alone are effective in primary prophylaxis of bleed from high-risk varices. Addition of propranolol does not decrease the probability of first bleed or death in patients on EVL. However, the recurrence of varices is lower if propranolol is added to EVL. 相似文献

Although both beta-blockade (BB) and endoscopic variceal ligation (EVL) are used for primary prevention of variceal bleeding (VB) in patients with cirrhosis with moderate to large esophageal varices (EVs), the more cost-effective option is uncertain. We created a Markov decision model to compare BB and EVL in such patients, examining both cost-effectiveness (cost per life year [LY]) and cost-utility (cost per quality-adjusted life year [QALY]). Outcomes included cost per LY, cost per QALY, proportions of persons with VB, TIPS, and all-cause mortality. EVL and BB were compared using the incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR). When considering only LYs, initial EVL exceeds the benchmark of 50,000 dollars/LY, with an ICER of 98,407 dollars. However, when quality of life (QoL) is considered, EVL is cost-effective compared to BB (ICUR of 25,548 dollars/QALY). In sensitivity analysis, EVL is cost-effective if the yearly risk of EV bleeding is > or = 0.26 (base case 0.15), the relative risk of bleeding on BB is > or = 0.69 (base case 0.58), or if the relative risk of bleeding with EVL is < 0.27 (base case 0.35). The ICUR favored EVL unless the relative risk of bleeding on BB is < 0.46, the relative risk of bleeding with EVL is > 0.46, or the time horizon is < or = 24 months. Whether EVL is "cost-effective" relative to BB therapy for primary prevention of EV bleeding depends on whether LYs or QALYs are considered. If only LYs are considered, then EVL is not cost-effective compared to BB therapy; however, if QoL is considered, then EVL is cost-effective. 相似文献

Endoscopic variceal ligation plus nadolol and sucralfate compared with ligation alone for the prevention of variceal rebleeding: a prospective, randomized trial 总被引:17,自引:0,他引:17
Lo GH Lai KH Cheng JS Chen MH Huang HC Hsu PI Lin CK 《Hepatology (Baltimore, Md.)》2000,32(3):461-465
Both beta-blockers and endoscopic variceal ligation (EVL) have proven to be valuable alternatives to sclerotherapy in the prevention of variceal rebleeding. Sucralfate is a mucosal protector. The effects of combinations of beta-blocker, band ligation, and sucralfate (triple therapy) remain unknown. A total of 122 patients with a history of esophageal variceal bleeding were randomized to receive EVL only (group A, 62 patients) or triple therapy (group B, 60 patients). The procedure for the triple therapy included ligation with the addition of sucralfate granules until variceal obliteration. In addition, nadolol was administered during the course of the study or until death. After a median follow-up of 21 months, recurrent upper gastrointestinal bleeding developed in 29 patients (47%) in group A and 14 patients (23%) in group B (P =.005). Recurrent bleeding from esophagogastric varices occurred in 18 patients in group A and 7 patients in group B (P =.001). Twenty-one patients in group A (50%) and 12 patients (26%) in group B experienced variceal recurrence after variceal obliteration (P <.05). Treatment failure occurred in 11 patients (18%) in group A and in 4 patients (7%) in group B (P =.05). Twenty patients from group A and 10 patients from group B died (P =.08); 9 and 4 of these deaths, respectively, were attributed to variceal hemorrhage (P =.26). The combination of ligation, nadolol, and sucralfate (triple therapy) proved more effective than banding ligation alone in terms of prevention of variceal recurrence and upper gastrointestinal rebleeding as well as variceal rebleeding. 相似文献

BACKGROUND: The combination treatment of band ligation plus sclerotherapy has been proposed to hasten variceal eradication. The aim of this study was to assess the efficacy of band ligation alone versus band ligation plus sclerotherapy in the prevention of recurrent variceal bleeding. METHODS: Eighty cirrhotic patients were randomized to group I (band ligation) with 41 patients or to group II (band ligation plus sclerotherapy) with 39 patients in whom polidocanol (2%) was injected 1 to 2 cm proximal to each band. RESULTS: At baseline, both groups were similar with regard to clinical, demographic and laboratory data. Mean follow-up time (standard error) for group I was 336.5 +/- 43.4 days and for group II 386.1 +/- 40.1 days (p = 0.4). No statistical differences were observed between group I and group II in relation to recurrence of bleeding (31.7% vs. 23%, p = 0.38), treatment failure (24.4% vs. 12. 8%, p = 0.18), death (39% vs. 30.8%, p = 0.44) and variceal eradication (65.8% vs. 74.4%, p = 0.40). Group II had a significantly higher number of complications than group I, 30.8% versus 7.3%, respectively (p = 0.05). The number of bleeding related deaths was higher in group I than in group II (22% vs. 10.3%, respectively; p = 0.15). CONCLUSIONS: No significant difference was observed between band ligation and band ligation plus sclerotherapy in prevention of recurrent variceal bleeding. Furthermore, there was a higher incidence of complications in the latter group. 相似文献

Primary prophylaxis of variceal hemorrhage: a randomized controlled trial comparing band ligation,propranolol, and isosorbide mononitrate 总被引:18,自引:0,他引:18
Lui HF Stanley AJ Forrest EH Jalan R Hislop WS Mills PR Finlayson ND Macgilchrist AJ Hayes PC 《Gastroenterology》2002,123(3):735-744
BACKGROUND & AIMS: This randomized controlled trial compared variceal band ligation (VBL), propranolol (PPL), and isosorbide-5-mononitrate (ISMN) in the prevention of first esophageal variceal bleed. METHODS: Over a 6-year period, 172 patients with cirrhosis, grade II or III esophageal varices that had never bled, were recruited; 44 into VBL, 66 into PPL, and 62 into ISMN. Baseline patient characteristics: age, 55 +/- 11 years; Child-Pugh score, 8 +/- 2; 65% alcohol-induced cirrhosis; follow-up period, 19.7 +/- 17.6 months (range, 0.13-72.1 months), were comparable in the 3 groups. RESULTS: On intention-to-treat analysis, variceal bleeding occurred in 7% of patients randomized to VBL, 14% to PPL, and 23% to ISMN. The 2-year actuarial risks for first variceal bleed were 6.2% (95% confidence interval [CI], 0.0%-15.0%) for VBL, 19.4% (95% CI, 0.1%-32.4%) for PPL, and 27.7% (95% CI, 14.2%-41.2%) for ISMN. A significant number of patients reported side effects with drug treatment (45% PPL and 42% ISMN vs. 2% VBL; P = 0.00), resulting in withdrawal from treatment in 30% of PPL and 21% of ISMN patients. There were no statistically significant differences in mortality rates in the 3 groups. In as-treated analysis, there was a statistically significant difference in actuarial risk for bleeding at 2 years between VBL and ISMN (7.5%, 95% CI, 2.5%-10.6% vs. 33.0%, 95% CI, 15%-49%, respectively, log rank test P = 0.03) but not between VBL and PPL. CONCLUSIONS: VBL was equivalent to PPL and superior to ISMN in preventing first variceal bleed. The side-effect profile for pharmacotherapy was considerable. 相似文献

Vasopressin/nitroglycerin infusion vs. esophageal tamponade in the treatment of acute variceal bleeding: a randomized controlled trial 总被引:1,自引:0,他引:1

Vasopressin infusion and esophageal tamponade are still widely used to arrest variceal bleeding, but no objective evidence exists on the superiority of either of the two procedures. In this study, 108 cirrhotic patients bleeding from varices were included in a prospective, randomized trial to investigate the comparative effectiveness and safety of balloon tamponade (using the Sengstaken-Blakemore tube for esophageal varices and the Linton-Nachlas tube for gastric varices) (n = 52) and intravenous vasopressin infusion (0.4 to 0.8 mu/min) plus intravenous nitroglycerin infusion (40 to 400 micrograms/min) (n = 56). Both treatments were maintained for 24-hr. The hemostatic efficacy according to the intention to treat was 86.5% for tamponade and 66% for pharmacological therapy (p less than 0.01). No significant differences were found with respect to rebleeding during the first 72 hr after treatment, mortality rate or side effects. These results suggest that esophageal tamponade is more effective than vasopressin/nitroglycerin infusion in the treatment of variceal bleeding in cirrhotic patients. 相似文献

BACKGROUND Variceal hemorrhage is associated with high mortality and is the cause of death for 20–30% of patients with cirrhosis. Nonselective β blockers(NSBBs) or endoscopic variceal ligation(EVL) are recommended for primary prevention of variceal bleeding in patients with medium to large esophageal varices.Meanwhile, combination of EVL and NSBBs is the recommended approach for the secondary prevention. Carvedilol has greater efficacy than other NSBBs as it decreases intrahepatic resistance. We hypothesized that there was no difference between carvedilol and EVL intervention for primary and secondary prevention of variceal bleeding in cirrhosis patients.AIM To evaluate the efficacy of carvedilol compared to EVL for primary and secondary prevention of variceal bleeding in cirrhotic patients METHODS We searched relevant literatures in major journal databases(CENTRAL,MEDLINE, and EMBASE) from March to August 2018. Patients with cirrhosis and portal hypertension, regardless of aetiology and severity, with or without a history of variceal bleeding, and aged ≥ 18 years old were included in this review.Only randomized controlled trials(RCTs) that compared the efficacy of carvedilol and that of EVL for primary and secondary prevention of variceal bleeding and mortality in patients with cirrhosis and portal hypertension were considered, irrespective of publication status, year of publication, and language.RESULTS Seven RCTs were included. In four trials assessing the primary prevention, no significant difference was found on the events of variceal bleeding(RR: 0.74,95%CI: 0.37-1.49), all-cause mortality(RR: 1.10, 95%CI: 0.76-1.58), and bleedingrelated mortality(RR: 1.02, 95%CI: 0.34-3.10) in patients who were treated with carvedilol compared to EVL. In three trials assessing secondary prevention, there was no difference between two interventions for the incidence of rebleeding(RR:1.10, 95%CI: 0.75-1.61). The fixed-effect model showed that, compared to EVL,carvedilol decreased all-cause mortality by 49%(RR: 0.51, 95%CI: 0.33-0.79), with little or no evidence of heterogeneity.CONCLUSION Carvedilol had similar efficacy to EVL in preventing the first variceal bleeding in cirrhosis patients with esophageal varices. It was superior to EVL alone for secondary prevention of variceal bleeding in regard to all-cause mortality reduction. 相似文献

A randomized controlled double-blind study was undertaken to assess the efficacy and safety of endoscopic neodymium:yttrium aluminum garnet (Nd:YAG) laser therapy for active esophageal variceal bleeding. Ten patients were randomized to the laser treatment group and 10 to a control group that received sham endoscopy and standard medical therapy. Initial hemostasis was achieved in seven laser-treated patients but in 0 of 10 controls receiving sham treatment (p less than 0.002). However, four of the seven who were initially controlled with laser therapy had rebleeding 12 to 48 hours later; thus, three of 10 laser patients had lasting hemostasis. The mean blood transfusion requirements were similar in both groups (laser = 7.3 units; control = 7.8 units). Six of the 10 laser-treated patients were discharged from the hospital and four died. There were seven hospital deaths in the control group and three patients were discharged (p = 0.22). In two patients in the treatment group, laser therapy increased bleeding. There were no perforations. 相似文献
