Recurrence of esophageal varices following endoscopic treatment and its impact on rebleeding: comparison of sclerotherapy and ligation

BACKGROUND/AIMS: Endoscopic variceal ligation is superior to sclerotherapy because of its lower rebleeding and complication rates. However, ligation is not without drawbacks due to a higher tendency to variceal recurrence. We conducted a randomized cohort study to delineate the long-term history of variceal recurrence following ligation and sclerotherapy, and to clarify the impact of recurrence on rebleeding and on the consumption of endoscopic treatment resources. METHODS: Two hundred cirrhotic patients with esophageal variceal bleeding were randomized to undergo maintenance endoscopic variceal sclerotherapy or ligation. RESULTS: One hundred and forty-one patients achieved variceal eradication and were regularly followed up for 2.2 to 6.7 (mean: 5.1 +/- 1.2) years. The demographic data, hepatic reserve, bleeding severity, and endoscopic features of both sclerotherapy (n=70) and ligation (n=71) showed no difference. Forty (57.1%) patients who underwent sclerotherapy experienced 58 recurrences of esophageal varices, in contrast to the 46 (64.8%) patients who underwent ligation and experienced 81 episodes of recurrence. Kaplan-Meier analysis showed that within 2 years variceal recurrence was more frequent for ligation than sclerotherapy, and the difference decreased thereafter. Multiple recurrence appeared more common with ligation (1/2/3/4/5 episodes of recurrence: 46/23/8/3/1 vs. 40/14/3/1/0, p=0.08). On multifactorial analysis, the endoscopic treatment method and red wale markings were the two factors determining variceal recurrence. Rebleeding from recurrent esophageal varices was unusual and showed no difference between the two groups (7/58 vs. 6/81, p>0.05). Rebleeding from gastric varices was more common after eradication by sclerotherapy (7/19 vs. 1/16, p=0.085) than by ligation. The number of sessions required for eradication of recurrent varices was no different between the two groups. CONCLUSIONS: Early recurrence and multiple recurrence of esophageal varices are more likely in patients undergoing endoscopic ligation, compared to sclerotherapy; however, the recurrence did not lead to a higher risk of rebleeding or require more endoscopic treatment.     

Improved long-term survival following complete eradication of esophageal varices by sclerotherapy

BACKGROUND/AIMS: Conflicting results have been reported concerning the effect of endoscopic injection sclerotherapy upon the long-term survival of cirrhotic patients with esophageal varix. The recurrence and rebleeding of esophageal varices seems to be an important factor influencing long-term survival. We investigated the long-term survival of patients after complete eradication of esophageal varices. METHODOLOGY: Forty patients treated by endoscopic injection sclerotherapy for acute esophageal variceal bleeding were studied. The recurrence rate of varices and the long-term survival of patients in whom complete eradication of esophageal varices was obtained were compared with those of patients in whom the eradication of varices was incomplete. RESULTS: The frequency of the recurrence/deterioration rate of varices and rebleeding in the complete eradication group was significantly lower than that in the incomplete eradication group (10.7% vs. 100%, 0% vs. 58.3%, respectively, p < 0.01). Accumulated 5-year survival rate of the complete eradication group was significantly higher than that of the incomplete eradication group (68.2% vs. 43.2%, p < 0.05). CONCLUSIONS: Complete eradication of esophageal varices by endoscopic injection sclerotherapy is effective both in preventing variceal re-bleeding and in improving the survival of cirrhotic patients with esophageal varices.     

Comparison of endoscopic variceal sclerotherapy with sequential endoscopic band ligation plus low-dose sclerotherapy for secondary prophylaxis of variceal hemorrhage: a prospective randomized study.

BACKGROUND: Endoscopic variceal sclerotherapy and band ligation both have certain limitations such as, respectively, esophageal complications and early recurrence of varices. METHODS: From February 1994 to March 1996, all consecutive patients with portal hypertension due to either cirrhosis or noncirrhotic portal fibrosis and a history of variceal bleeding were included in a prospective study and randomly assigned to receive either endoscopic variceal sclerotherapy alone or endoscopic variceal band ligation plus low-dose endoscopic variceal sclerotherapy. RESULTS: Of 69 patients, 34 were randomly assigned to receive endoscopic variceal sclerotherapy alone; 35 received endoscopic variceal band ligation plus endoscopic variceal sclerotherapy. Complete variceal eradication rates (85% vs. 80%) and the number of endoscopic sessions required for eradication (6.61 +/- 2.94 vs. 7.85 +/- 3.31) were similar in the endoscopic variceal sclerotherapy and endoscopic variceal band ligation plus endoscopic variceal sclerotherapy groups, respectively. The mean volume of sclerosant required in the combined group (54.94 +/- 33.74 mL) was significantly less than that in the endoscopic variceal sclerotherapy group (81.91 +/- 34.80 mL). The complication and recurrent bleeding rates were significantly higher in the endoscopic variceal sclerotherapy group than those in the combined group (20% and 16% vs. 3% and 3%, respectively). CONCLUSIONS: Both endoscopic variceal sclerotherapy and endoscopic variceal band ligation plus endoscopic variceal sclerotherapy were comparable in eradicating varices but the combined technique was associated with significantly lower complication and recurrent bleeding rates.     

Endoscopic ligation compared with sclerotherapy for bleeding esophageal varices in children with extrahepatic portal venous obstruction

Endoscopic sclerotherapy is an effective treatment for bleeding esophageal varices, but it is associated with significant complications. Endoscopic ligation, a new form of endoscopic treatment for bleeding varices, has been shown to be superior to sclerotherapy in adult patients with cirrhosis. To determine the efficacy and safety of endoscopic sclerotherapy and ligation, the 2 methods were compared in a randomized control trial in 49 children with extrahepatic portal venous obstruction who had proven bleeding from esophageal varices. Twenty-four patients were treated with sclerotherapy and 25 with band ligation. No significant differences were found between the sclerotherapy and ligation groups in arresting active index bleeding (100% each) and achieving variceal eradication (91.7% vs. 96%, P =.61). Band ligation eradicated varices in fewer endoscopic sessions than did sclerotherapy (3.9 +/- 1.1 vs. 6.1 +/- 1.7, respectively, P <.0001). The rebleeding rate was significantly higher in the sclerotherapy group (25% vs. 4%, P =.049), as was the rate of major complications (25% vs. 4%, P =.049). After eradication, esophageal variceal recurrence was not significantly different in patients treated by ligation than by sclerotherapy (17.4% vs. 10%, P =.67). In conclusion, variceal band ligation in children is a safe and effective technique that achieves variceal eradication more quickly, with a lower rebleeding rate and fewer complications compared with sclerotherapy.     

Endoscopic ligation vs. sclerotherapy in adults with extrahepatic portal venous obstruction: a prospective randomized study

BACKGROUND: Endoscopic sclerotherapy is a well-established treatment for bleeding esophageal varices, although it has a substantial complication rate. A prospective randomized trial was conducted to determine whether endoscopic variceal ligation is safer and more effective than sclerotherapy in adults with bleeding esophageal varices because of extrahepatic portal venous obstruction. METHODS: Thirty-six patients underwent sclerotherapy and 37 had band ligation. RESULTS: Ligation and sclerotherapy were equally effective for achieving variceal eradication (94.6% vs. 91.7%, respectively; p=0.67). However, ligation achieved eradication with fewer endoscopic sessions (3.7 [1.2] vs. 7.7 [3.3]; p <0.0001) and within a shorter time interval (50.1 [17.7] days vs. 99 [54.8] days; p <0.0001). In the ligation group, recurrent bleeding was less frequent (2.7% vs. 19.4%; p=0.028; however, Bonferroni correction for multiple testing removes this significance) and the rate of major complications was lower (2.7% vs. 22.2%; p=0.014). Total cost per patient was significantly higher in the sclerotherapy vs. the ligation group ($216.6 [71.8] vs. $182.6 [63.4]; p=0.035). During the follow-up period after variceal eradication, no significant differences were found between the sclerotherapy and the ligation groups with respect to recurrent bleeding (3% vs. 2.9%; p=1.0), esophageal variceal recurrence (9.1% vs. 11.4%; p=1.0), and formation of new gastric varices (9.1% vs. 14.3%; p=0.51). CONCLUSIONS: Variceal band ligation is superior to sclerotherapy, because it is less costly and achieves variceal eradication more quickly, with lower relative frequencies of recurrent variceal bleeding and complications.

Adjuvant sclerotherapy after ligation for the treatment of esophageal varices: a prospective, randomized long-term study

BACKGROUND: To assess the efficacy of adjuvant sclerotherapy after banding for the treatment of esophageal varices, a randomized trial was carried out of endoscopic variceal ligation (EVL) alone with sequential sclerotherapy versus sequential ligation-sclerotherapy (SLS) after banding with respect to variceal eradication, associated complications, and recurrence of varices. METHODS: One hundred patients qualified for this study. Fourteen patients were not included for the following reasons: 6 chose not to participate, 4 had fundal varices, and 4 had some form of cancer. Of the remaining 86 patients in the study, 42 underwent EVL alone and the other 44 SLS. Variceal ligation was begun in the region of the gastroesophageal junction, with subsequent ligatures applied cephalad 3 to 5 cm; ligation was repeated every 2 weeks until variceal obliteration. For SLS, ligation was also begun in the region of the gastroesophageal junction and repeated until varices were reduced to F1 size. Subsequently, these patients underwent sclerotherapy with between 6 and 8 mL of sodium tetradecyl sulfate (free hand technique). RESULTS: No significant differences were found between EVL alone and SLS with regard to variceal eradication, development of associated complications, and recurrent bleeding during a follow-up of 2 years. The probability of variceal recurrence requiring further treatment after 1 year was 14% for the SLS group and 26% for EVL group patients. Another year later, the probability of variceal recurrence was 24% and 45%, respectively, for the SLS and EVL groups. CONCLUSIONS: Because a significantly lower rate of variceal recurrence was found for SLS patients, sequential sclerotherapy followed by ligation to eradicate those varices too small to easily band may be a better procedure.     

Detachable endoloop vs. elastic band ligation for bleeding esophageal varices

BACKGROUND: Variceal bleeding is a serious complication with a mortality rate that ranges from 20% to 50%. Patients who have variceal hemorrhage usually are treated by endoscopic injection sclerotherapy or elastic band ligation to eradicate the varices. Endoloop ligation is a newly developed technique for achieving hemostasis and variceal eradication. This study compared endoloop ligation with elastic band ligation in patients with acute esophageal variceal bleeding. METHODS: Fifty patients with acute esophageal variceal bleeding were recruited: 25 were treated by elastic band ligation and 25 by endoloop ligation. RESULTS: Although the number of patients in whom bleeding recurred during a follow-up period of 6 months was smaller in the endoloop group (12%) vs. the band group (28%), this difference was not statistically significant. Furthermore, no statistically significant difference was found between the two groups with respect to the number of patients in whom variceal eradication was achieved, the number of treatment sessions required for variceal eradication, or the frequency of variceal recurrence. The total cost for variceal obliteration by endoloop ligation was 342 dollars per patient, whereas, the total cost of variceal eradication by elastic band ligation was 356 dollars per patient. The endoloop had certain technical advantages over band application: a better field of vision, tighter application, good results with junctional varices, and a lack of strain exerted by the device on the endoscope. CONCLUSIONS: Endoloop ligation is a promising new technique for management of patients with bleeding esophageal varices.     

Endoscopic management for bleeding esophageal varices: sclerotherapy versus sclerotherapy plus band ligation versus band ligation alone. One year experience at a main hospital in Saudi Arabia.

BACKGROUND/AIMS: This study was done retrospectively to compare the outcome of sclerotherapy alone, band ligation alone and band ligation alternating with sclerotherapy in treatment of esophageal varices. METHODOLOGY: During 1 year 30 patients were admitted with variceal bleeding. They received either injection sclerotherapy (8 patients) or band ligation (11 patients), and 11 patients had a combination of both either during first bleed or during follow-up therapy, which is more than 2 sessions in each group. RESULTS: The success rate for stopping first bleeding was 100% in the band ligation and sclerotherapy alone group. The rebleeding rate was 27% in the combination group, 9% in the band ligation group, and none had rebleeding in the sclerotherapy group during follow-up. Eradication of varices was observed in 33% of patients after a second set of sclerotherapy and band ligation. CONCLUSIONS: Our study showed no significant difference between sclerotherapy versus band ligation in stopping initial bleeding or eradication of varices during the follow-up period, but there was a difference in re-bleeding rates among the three groups.     

Argon plasma coagulation prevents variceal recurrence after band ligation of esophageal varices: preliminary results of a prospective randomized trial

BACKGROUND: Endoscopic variceal ligation is an established procedure for eradication of esophageal varices. However, varices frequently recur after endoscopic variceal ligation. Argon plasma coagulation has been used as supplemental treatment for eradication of varices and for prevention of variceal recurrence in small uncontrolled series. The aim of this study was to determine whether argon plasma coagulation is effective in reducing variceal recurrence after endoscopic variceal ligation. METHODS: Thirty patients with cirrhosis, a history of acute esophageal variceal bleeding, and eradication of varices by endoscopic variceal ligation were randomized to argon plasma coagulation (16 patients) or observation (14 patients). The 2 groups were similar with respect to all background variables including age, Child-Pugh score, presence of gastric varices, and degree of portal hypertensive gastropathy. In the argon plasma coagulation group, the entire esophageal mucosa 4 to 5 cm proximal to the esophagogastric junction was thermocoagulated circumferentially with argon plasma coagulation in 1 to 3 sessions performed at weekly intervals. Endoscopy was performed every 3 months to check for recurrence of varices in both groups. RESULTS: During the course of the study, no serious complication was noted. After argon plasma coagulation, transient fever occurred in 13 patients and 8 complained of dysphagia or retrosternal pain/discomfort. Mean follow-up for all patients was 16 months (range 9-28 months). No recurrence of varices or variceal hemorrhage was observed in the argon plasma coagulation group, whereas varices recurred in 42.8% (6/14) of the patients in the control group (p < 0.04) and bleeding recurred in 7.2% (1/14). CONCLUSIONS: Argon plasma coagulation of the distal esophageal mucosa after eradication of esophageal varices by endoscopic variceal ligation is safe and effective for reducing the rate of variceal recurrence.     

Randomized trial of ligation versus combined ligation and sclerotherapy for bleeding esophageal varices.

BACKGROUND: Endoscopic band ligation combined with sclerotherapy has been postulated to be superior to ligation alone for the treatment of esophageal variceal bleeding. METHODS: A randomized trial of ligation versus combined ligation and sclerotherapy was designed to determine whether combined therapy results in faster eradication of varices compared to ligation alone. Sixty patients were randomized to undergo band ligation or ligation combined with injection of 1 to 2 mL of polidocanol (1%) into each variceal column immediately proximal to the previously placed bands. Therapy was repeated at 1- or 2-week intervals until variceal eradication was achieved. Follow-up endoscopy was performed at 3 months and then at 6-month intervals. RESULTS: The demographic and clinical characteristics of the 31 patients who underwent ligation were similar to those of the 29 who received combined treatment. Sixty percent of the patients had cirrhosis due to viral hepatitis. No significant differences were found between the combined and ligation alone groups in arresting active bleeding [9 of 9 (100%) vs. 6 of 7 (86%)], units of blood transfusion (3 +/- 0.8 vs. 2 +/- 0.6), number of sessions required to eradicate varices (3.8 +/- 0.5 vs. 3.6 +/- 0.4), treatment failure [2 (17%) vs. 4 (14%)], esophageal varix recurrence [6 (21.%) vs. 2 (6%)], gastric varices formation [4 (14%) vs. 1 (3%)], stricture [1 (3%) vs. 0 (0%)], recurrent bleeding [5 (17%) vs. 7 (23%)], other complications [10 (34%) vs. 9 (29%)], or death [3 (10%) vs. 7 (23%)] during a follow-up period of up to 36 months. CONCLUSIONS: Combined ligation and sclerotherapy does not reduce the number of endoscopic treatment sessions required for variceal eradication and offers no benefit over ligation alone. Because of the lack of benefit, the added procedure time, and the cost, we do not advocate combination therapy, and ligation alone remains the best endoscopic treatment.     

Endoscopic variceal ligation is superior to combined ligation and sclerotherapy for esophageal varices: A multicenter prospective randomized trial

Patients who have bled from varices remain at risk for rebleeding. There is interest in methods that would enable rapid eradication of varices. The present trial was designed to study whether combining ligation with sclerotherapy will allow quicker eradication of varices than either modality alone. Patients with bleeding esophageal varices were randomized into ligation or combination therapy groups. Patients in the ligation group were treated with endoscopic rubber band ligation alone. In combination group patients, each variceal column was ligated distally and 1 mL of ethanolamine was injected proximal to each ligated site. Subsequent treatment sessions were at 7- to 14-day intervals until varices were eradicated. The clinical and endoscopic characteristics of 25 patients in the ligation group were similar to those of 22 patients in the combination group. Follow-up was up to 30 months. Active bleeding was controlled in 100% of patients in the ligation group and 75% of those in combination group (P = NS). It took 3.3 +/- .4 (range, 1-7) sessions to eradicate varices with ligation and 4.1 +/- .6 (1-7) with combination therapy (P = NS). Survival (four deaths in ligation group, 8 in combination group), rebleeding rate (25% vs. 36%), and varix recurrence (16% vs. 23%) also were similar. There were more complications with combination therapy, including deep ulcers (65% vs. 20%; P < .05); dysphagia (30% vs. 0%; P < .05), with three strictures requiring dilation; and pain (30% vs. 10%; P = NS). Our results show that sclerotherapy combined with ligation offers no benefit over ligation alone. The higher complication rate with combination therapy does not warrant this approach.(Hepatology 1997 Jan;25(1):71-4)     

Do we need endoscopic sclerotherapy of oesophageal varices or the last turn off the light

For the primary prophylaxis of variceal bleeding endoscopic band ligation has been shown to be as effective as non-selective beta-blockers (carvedilol), but variceal injection sclerotherapy is not generaly recommended in this setting because of higher rate of complications and lower effect in reducing either bleeding or mortality. Endoscopic management of acutely bleeding gastroesophageal varices includes injection sclerotherapy, rubber band ligation, and variceal obturation with tissue adhesives. Variceal injection sclerotherapy remains a quick, simple and cheap technique for the control of active bleeding from esophageal varices, but is associated with more rebleeding than variceal band ligation, which is now preferred also for lower rate of complications. Endoscopic sclerotherapy has increasingly been replaced by ligation also in secondary prophylaxis of variceal bleeding. The studies showed that band ligation can eradicate varices in fewer sessions, re-bleeding and complications were fewer in comparison with variceal injection sclerotherapy. Because of the reduced efficacy, severe complications, and the high mortality associated with using conventional sclerosants in acute bleeding gastric varices, the technique of injecting tissue adhesives has been studied, described and used despite numerous complications. Endoscopic injection sclerotherapy of esophageal varices remains usable as an oldest method in arresting of this hemorrhage only in rare cases when the band ligation is not available.     

Endoscopic band ligation plus argon plasma coagulation versus scleroligation for eradication of esophageal varices

Background and Aim: The aim of this study was to evaluate endoscopic band ligation plus argon plasma coagulation versus scleroligation. Methods: Patients were randomized to: Group I, 50 patients subjected to endoscopic injection sclerotherapy; Group II, 50 patients subjected to variceal band ligation; Group III, 50 patients subjected to combined endoscopic sclerotherapy and band ligation; and Group IV, 50 patients subjected to endoscopic band ligation plus argon plasma coagulation. Results: A comparison of the number of therapeutic sessions showed that group III underwent significantly fewer sessions. As regards post‐treatment complications, Group I showed a high incidence of transient pyrexia, transient dysphagia and/or retrosternal pain and ulceration, while in group II a higher incidence of rebleeding was demonstrated, as well as a higher incidence of esophageal varix recurrence after eradication during the follow‐up period. A higher mortality incidence was detected in groups I and II. The follow‐up incidence did not significantly differ between the different study groups. Conclusion: Scleroligation allows very rapid eradication of varices, has a low recurrence rate, avoids the disadvantage of high recurrence of band ligation alone, and does not require special skills over sclerotherapy or band ligation. Also, band ligation plus argon plasma coagulation allows for very rapid eradication of varices, and a low recurrence rate, with no obvious recorded complications, but it has the disadvantage of being the most expensive technique and requires special equipment that is only available in a few endoscopic centers.

Combined ligation and sclerotherapy versus ligation alone for secondary prophylaxis of esophageal variceal bleeding: a meta-analysis

OBJECTIVES: Variceal ligation has been shown to be superior to sclerotherapy in prevention of rebleeding and improving survival in patients with cirrhosis. However, 25% of patients will rebleed before completion of treatment. A number of trials have compared the combination of ligation and sclerotherapy to ligation alone in achieving rapid and complete eradication of esophageal varices, with conflicting results. METHODS: Two reviewers independently identified seven randomized, controlled trials that compared endoscopic variceal ligation with the combination of sclerotherapy and ligation for the treatment of esophageal varices. Studies were identified by searching MEDLINE, reviewing references from retrieved articles, and scanning abstracts from conference proceedings. For each outcome, odds ratios (ORs) were calculated using fixed-effects and random-effects models. The Mantel-Haenszel test for statistical heterogeneity was used to assess the validity of combining results from individual studies. RESULTS: No significant difference was seen in cessation of actively bleeding varices (OR = 1.01, 95% CI = 0.43-2.36), variceal rebleeding (OR = 1.12, CI = 0.69-1.81), and mortality (OR = 1.1, CI = 0.70-1.74) in patients with variceal ligation versus patients receiving the combination treatment of ligation and sclerotherapy. Treatment sessions required to achieve complete variceal eradication were similar in the two treatment arms. A significantly higher incidence of esophageal stricture was seen in combination therapy (p < 0.001). CONCLUSIONS: The combination of ligation and sclerotherapy offers no advantage over ligation alone in prevention of rebleeding and in reduction of mortality. It is also associated with a higher complication rate of esophageal stricture.     

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.     

Comparison of characteristics of recurrent esophageal varices after endoscopic ligation versus endoscopic ligation plus sclerotherapy

BACKGROUND/AIMS: The characteristics of recurrent esophageal varices after endoscopic variceal ligation (EVL) plus endoscopic injection sclerotherapy (EIS) versus EVL alone, including the number of additional treatments and patterns of recurrence have been compared. METHODOLOGY: Thirty-four patients with cirrhosis and esophageal varices were treated by EVL alone (EVL group), and 46 patients were treated by EVL followed by extravariceal injection sclerotherapy (EVL+extraEIS group). RESULTS: Fewer treatment sessions were needed (p<0.005), and more O-rings were required (p<0.0001) in the EVL group than in the EVL+extraEIS group. The 1- and 3-year cumulative recurrence rates were higher in the EVL group (81.3% and 93.8%) than in the EVL+extraEIS group (62.8% and 91.5%) (p<0.05). Endoscopic examination at first recurrence showed varices of a more severe form (p<0.001), but less frequently having the red color sign (p<0.0001), and intramucosal venous dilatation (p<0.0001) in the EVL group than in the EVL+extraEIS group. The number of rehospitalizations for additional treatment was lower (p<0.0001) and more patients could be managed with only endoscopic treatment for recurrent varices in the EVL group than in the EVL+extraEIS group (p<0.05). CONCLUSIONS: Even if the overall rate of variceal recurrence was higher, fewer treatment sessions were needed, and the number of rehospitalizations for these additional treatments was lower in the EVL group than in the EVL+extraEIS group. Multiple sessions of EVL are an effective strategy for the treatment of esophageal varices.     

Evaluation of the effects of combined endoscopic variceal ligation and splenectomy with pericardial devascularization on esophageal varices

INTRODUCTION In patients with portal hypertension, collaterals should be established to reduce the high portal pressure, and the hemodynamic indicators of such collaterals have been used for the evaluation of therapeutic effects. According to the location…     

A new technique of combined endoscopic sclerotherapy and ligation for variceal bleeding

AIM: To develop a technique of combined endoscopic sclerotherapy and ligation (ESL) in which both techniques of endoscopic sclerotherapy (ES) and endoscopic variceal ligation (EVL) can be optimally used. METHODS: ESL was performed in 10 patients (age 46.4+/-7.9; 9 males, 1 female) with cirrhosis of liver using sclerotherapy needle and Speedband, Superview multiple band ligater (Boston Scientific, Microvasive, Watertown, MA). A single band was placed 5-10 cm proximal to the gastro-esophageal junction over each varix from proximal to distal margin, followed by intravariceal injection of 1.5 % ethoxysclerol (4 ml each) 2 to 3 cm proximal to the gastroesophageal junction on the ligated varices distal to deployed band. EVL was then performed at the injection site. Similarly other varices were also injected and ligated from distal to proximally. In the subsequent sessions, ES alone was performed to sclerose small varices at the gastroesophageal junction. RESULTS: ESL was successfully performed in all patients. A median of 3 (ESL 1, ES 2) sessions (ranged 1-4) were required to eradicate the varices in 9 (90 %) of 10 patients. Recurrence of varices without bleed was seen in 1 patient during a mean follow-up of 10.3 months (ranged 6-15). Two patients died of liver failure. None died of variceal bleeding. None of the patients had procedure related complications. CONCLUSION: ESL may be useful in the fast eradication of esophageal varices. However, randomised controlled trials are required to find out its relative efficacy and impact on variceal recurrence in comparison to ES or EVL.
