Rubber Band Ligation for Esophageal Varices
Endoscopic variceal band ligation (EVL) is the first-line endoscopic treatment for both acute esophageal variceal bleeding and secondary prophylaxis after a bleeding episode, and it is superior to sclerotherapy in reducing rebleeding, mortality, and complications. 1
Acute Variceal Bleeding Management
Immediate Endoscopic Intervention
Variceal band ligation is the method of first choice for controlling active esophageal variceal bleeding once the patient is hemodynamically stable. 1
If banding is technically difficult due to continued bleeding or the technique is unavailable, endoscopic variceal sclerotherapy should be performed as an alternative. 1
Upper endoscopy should be performed within 12 hours of admission once hemodynamic stability is achieved and the airway is protected. 2
Superiority Over Sclerotherapy
Meta-analysis of seven randomized trials (547 patients) demonstrated that variceal band ligation significantly reduces rebleeding (OR 0.52,95% CI 0.37–0.74), mortality (OR 0.67,95% CI 0.46–0.98), and complications such as esophageal stricture (OR 0.10,95% CI 0.03–0.29) compared to sclerotherapy. 1
EVL is more effective than sclerotherapy in decreasing the risk of rebleeding with fewer complications, and it achieves obliteration of esophageal varices more rapidly. 1
Secondary Prophylaxis (Prevention of Rebleeding)
Optimal Treatment Strategy
The combination of endoscopic variceal ligation plus non-selective beta-blockers (NSBBs) is recommended as the primary treatment for preventing esophageal variceal rebleeding. 1
If combination treatment is difficult to perform, use of NSBBs or EVL alone is recommended. 1
Following control of active variceal bleeding, varices should be eradicated using variceal band ligation as the method of first choice. 1
Banding Technique and Follow-up
Each varix should be banded with a single band at weekly intervals until variceal eradication is achieved. 1
The use of the overtube should be avoided because it is associated with increased complications. 1
Following successful eradication, patients should undergo endoscopy at three months and six-monthly thereafter, with retreatment if varices recur. 1
Primary Prophylaxis (Prevention of First Bleed)
Treatment Selection
Non-selective beta-blockers should be the first treatment option for primary prophylaxis because of less severe side effects compared to band ligation. 3
EVL is an effective alternative when beta-blockers are contraindicated or not tolerated. 3
Meta-analysis shows that both beta-blockers and variceal band ligation reduce mortality compared to no intervention (beta-blockers: HR 0.49,95% CI 0.36 to 0.67; variceal band ligation: HR 0.51,95% CI 0.35 to 0.74). 4
Important Caveat
Variceal band ligation has a higher number of serious adverse events compared to beta-blockers (rate ratio 10.49,95% CrI 2.83 to 60.64), with complications including esophageal ulceration, dysphagia, odynophagia, retrosternal pain, and fever. 5, 4
The incidence of non-serious side effects with banding is much higher in patients with small varices compared to large varices (ulcers: 30.5% vs 8.7%; heartburn: 39.2% vs 17.4%). 5
Rescue Therapy for Treatment Failure
If primary treatment for esophageal variceal rebleeding fails, transjugular intrahepatic portosystemic shunt (TIPS) placement should be considered as rescue therapy. 1
TIPS reduces rebleeding compared to endoscopic treatment (0% vs 29%, P=0.001) but is associated with higher rates of hepatic encephalopathy (35% vs 14%, P=0.035). 1
Liver transplantation should be considered in patients with recurrent variceal rebleeding. 1
Procedural Safety Considerations
In patients with stable cirrhosis and abnormal laboratory tests undergoing prophylactic band ligation, administration of blood products or factor concentrates with the aim of avoiding post-ligation bleeding is not recommended. 1
Patients undergoing band ligation should be monitored for bleeding complications in the same manner as patients without cirrhosis. 1
