Endoscopic Variceal Ligation vs Carvedilol for the Prevention of First Esophageal Variceal Bleeding in Patients With HCC

EVL will be performed and repeated every 3 to 4 weeks until the EVs are eradicated. Following this, patients will undergo regular upper gastrointestinal endoscopic surveillance, initially every three months for a total of two sessions, then every six months for a total of two sessions, and subsequently annually. If EVs are found to recur during surveillance, additional EVL will be performed every 3 to 4 weeks until the varices are again eradicated endoscopically.

The initial dosage of carvedilol is set at 6.25 mg daily. In the absence of hypotension (systolic blood pressure \< 90 mmHg), bradycardia (resting heart rate \< 55 beats per minute), or other adverse effects, hospitalized patients may have their dosage increased to 12.5 mg daily after 3 days, while outpatient patients may increase their dosage to 12.5 mg daily after 7 days. This dosage represents the target dose for the trial.
