Esophageal Variceal Ligation (EVL)

This procedure is often performed under sedation or anesthesia, with a ligation device and flexible endoscope selected when necessary. Varicose veins are usually assessed under direct endoscopic vision, and after positioning, they are ligated point by point with ligation rings to collapse and fibrose the veins, reducing the risk of bleeding. Suction and irrigation are used during the procedure, and vital signs are continuously monitored. Postoperatively, attention is paid to hematemesis, melena, chest tightness, and swallowing discomfort, and follow-up endoscopy is arranged in conjunction with the assessment to gradually remove residual varices. The above is general health information, not medical advice; the specific plan is subject to specialist evaluation and hospital protocol.
