Endoscopic variceal ligation plus propranolol versus endoscopic variceal ligation alone in primary prophylaxis of variceal bleeding

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.

Influence of endoscopic variceal ligation on oesophageal motility

BACKGROUND: To determine the change of oesophageal manometry in patients with oesophageal varices before and after oesophageal variceal ligation (EVL). METHODS: Forty-five patients who had liver cirrhosis and oesophageal varices with high risk of bleeding were managed by EVL. Oesophageal manometry was performed just prior to the ligation and 4-6 weeks after obliteration of varices. Another 45 age- and sex-matched patients without hepatic, oesophageal or systemic disease served as the control group. RESULTS: At 5 cm above the lower oesophageal sphincter (LES), the amplitude of the contractive wave was significantly lower in patients before EVL (56.9 +/- 31.8 vs 80.1 +/- 30.1, P< 1.05) and returned to the level of control subjects after EVL (76.5 +/- 37.0 vs 80.1 +/- 30.1, P> 0.05). At 10 cm above LES, the amplitude of the contractive wave was significantly lower in patients before and after EVL than the control group (54.3 +/- 29.2 vs 68.1 +/- 29.5, 54.2 +/- 26.0 vs 68.1 +/- 29.5, respectively, P< 0.05). The percentage of tertiary waves was significantly higher in patients before and after EVL than in the control group (31.4 +/- 36.6 vs 5.8 +/- 15.1, 26.9 +/- 32.9 vs 5.8 +/- 15.1, respectively, P< 0.05). However, no significant swallowing disturbance was noted in patients after EVL. There was significantly greater LES length in patients before EVL (4.0 +/- 0.9 vs 3.4 +/- 0.7, P<0.05) but there was no significant difference in the LES length after EVL as compared with the control group. Eighty-six per cent (39/45) of patients developed paraoesophageal varices and 31% (14/45) developed new varices 6 months after variceal obliteration. However, there was no significant difference in manometry at the time of variceal obliteration between patients with variceal recurrence and those without. CONCLUSIONS: The presence of varices affected oesophageal motility. However, such abnormality had little clinical significance. Endoscopic variceal ligation normalized oesophageal motility and may not induce abnormal oesophageal motility. The manometric change can not be used to predict the recurrence of varices in cirrhotic patients after variceal obliteration.

A meta-analysis of endoscopic variceal ligation for primary prophylaxis of esophageal variceal bleeding

Despite publication of several randomized trials of prophylactic variceal ligation, the effect on bleeding-related outcomes is unclear. We performed a meta-analysis of the trials, as identified by electronic database searching and cross-referencing. Both investigators independently applied inclusion and exclusion criteria, and abstracted data from each trial. Standard meta-analytic techniques were used to compute relative risks and the number needed to treat (NNT) for first variceal bleed, bleed-related mortality, and all-cause mortality. Among 601 patients in 5 homogeneous trials comparing prophylactic ligation with untreated controls, relative risks of first variceal bleed, bleed-related mortality, and all-cause mortality were 0.36 (0.26-0.50), 0.20 (0.11-0.39), and 0.55 (0.43-0.71), with respective NNTs of 4.1, 6.7, and 5.3. Among 283 subjects from 4 trials comparing ligation with beta-blocker therapy, the relative risk of first variceal bleed was 0.48 (0.24-0.96), with NNT of 13; however, there was no effect on either bleed-related mortality (relative risk [RR], 0.61; confidence interval [CI], 0.20-1.88) or all-cause mortality (RR, 0.95; CI, 0.56-1.62). In conclusion, compared with untreated controls, prophylactic ligation reduces the risks of variceal bleeding and mortality. Compared with beta-blockers, ligation reduces the risk for first variceal bleed but has no effect on mortality. Prophylactic ligation should be considered for patients with large esophageal varices who cannot tolerate beta-blockers. Subsequent research should further compare ligation and beta-blockers to determine the effect on mortality, and measure ligation's cost-effectiveness.     

Oesophageal perforation following endoscopic variceal ligation and balloon tamponade

Endoscopic variceal ligation (EVL) related complication is rarely reported. A case is presented of a 74 year old man with oesophageal variceal bleeding who developed oesophageal perforation following EVL and balloon tamponade. An oesophageal wall defect was induced by EVL and tissue repair was hindered by decompensated liver reserve and shock status; concomitant balloon tamponade precipitated oesophageal perforation. The case is reported to draw attention to oesophageal perforation after concurrent use of balloon tamponade and EVL.     

Effective treatment for duodenal variceal bleeding using endoscopic ligation

Duodenal variceal rupture is rare, and there is little agreement on the best therapeutic option. A 72-year old man treated for liver cirrhosis with HCV visited the emergency room complaining of dizziness and tarry stool. Fiberscope images showed varices (F2CbRC+) with white plaques at the horizontal region of the duodenum. The patient was treated using endoscopic variceal ligation (EVL), and no more bleeding has been detected.     

Factors predicting success of endoscopic variceal ligation for secondary prophylaxis of esophageal variceal bleeding

Introduction: Endoscopic obliteration of esophageal varices by endoscopic variceal ligation (EVL) is an effective form of secondary prophylaxis. However, there is no consensus regarding the technical aspects of EVL for secondary prophylaxis. The present study compares the technical aspects of EVL (frequency of sessions, number of sessions and number of bands used) in patients who rebled following secondary prophylaxis of esophageal varices by EVL compared to those who did not rebleed. Methods: All patients who underwent EVL for treatment of acute variceal bleeding followed by EVL for secondary prophylaxis and who subsequently developed recurrent variceal bleeding at Mayo Clinic, Rochester between January 1995 and May 2003 were identified. A control group of patients undergoing EVL for secondary prophylaxis who did not rebleed was identified. Results: During the study period, 216 patients with acute esophageal variceal hemorrhage underwent emergent EVL treatment with follow‐up EVL for secondary prophylaxis, of whom 20 (9.3%) subsequently rebled. Both rebleeding and non‐rebleeding patient groups were well‐matched with respect to liver function (Child–Pugh class), number and size of variceal trunks, endoscopic stigmata of hemorrhage and beta‐blocker usage. The median interval between EVL sessions in the rebleeding group (2 weeks, interquartile range 0–2 weeks) was significantly shorter compared to the non‐rebleeding group (5 weeks, interquartile range 3–7 weeks; P = 0.004). Adjusting for age, gender, and Child–Pugh class, interbanding interval ≥ 3 weeks was associated with increased likelihood of not rebleeding, hazard ratio 3.84 (95% confidence interval: 1.69–11.79; P = 0.0007). Conclusions: These findings demonstrate the importance of technical aspects of EVL on patient outcome, suggesting the benefit of longer interbanding intervals. Future prospective studies are required to define the optimal intersession interval. Standardizing procedural aspects of EVL will aid in objectively evaluating the benefit of this procedure when compared to other modalities such as medical treatment.     

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.     

内镜下食管静脉曲张结扎术后早期再出血的预防和治疗

目的：总结内镜下食管静脉曲张结扎术(EVL)后早期再出血及出血后死亡的发生率，并评价10年来结扎术后早期再出血药物应用的趋势以及药物预防措施的效果。方法：总结我院10年来593例次肝硬化和(或)肝癌单纯EVL治疗的资料，统计接受EVL治疗后早期再出血及出血后死亡的发生率，分析预防结扎术后早期再出血药物应用的趋势以及药物预防措施的效果。结果：EVL术后早期再出血的发病率为4．7％(28／593)，出血后死亡率为64．3％(18／28)。质子泵抑制剂、生长抑素、胃黏膜保护剂和凝血酶的使用，并不能使早期再出血率及出血后死亡率下降。结论：目前的药物预防并未带来EVL后早期再出血及出血后死亡率的下降，出血后是否应用质子泵抑制剂影响出血后死亡率。

The influence of endoscopic variceal ligation on the portal pressure gradient in cirrhotics

BACKGROUND/AIMS: After variceal eradication by endoscopic ligation, fundal varices and worsening of portal hypertensive gastropathy can occur. The aim of this study is to verify the impact of the eradication of esophageal varices by endoscopic ligation on the portal pressure gradient, worsening of portal hypertensive gastropathy and development of fundal varices. METHODOLOGY: Twenty-two (15M/7F, mean age: 54.5 years) cirrhotics with previous variceal bleeding were submitted to measurement of hepatic venous pressure gradient before and after variceal eradication by endoscopic ligation. RESULTS: The mean hepatic venous pressure gradient in the first measurement was 14.1 mmHg and after eradication, 13.5 mmHg (p = 0.403). After eradication, 12 patients experienced a reduction in portal pressure and 10, an elevation. Three patients developed fundal varices. Their mean gradient before treatment was 22 mmHg and 18.8 mmHg after therapy (p = 0.368). The gastropathy worsened in 9 patients (mean gradient before therapy of 15.2 mmHg; and 16.1 mmHg after treatment) (p = 0.303). The initial pressure gradient of these patients was not different from the other 13 cases (p = 0.463). CONCLUSIONS: The esophageal variceal eradication by endoscopic band ligation does not alter the hepatic venous pressure gradient. There is no significant variation in the portal pressure of patients in whom there was a worsening of portal hypertensive gastropathy or fundal varices development.
