Endoscopic Treatment of Esophageal Varices: Endoscopic Variceal Ligation Using a Multi-Band Ligator
Endoscopic variceal ligation (EVL), a safe and effective treatment for esophageal varices, has undergone rapid progress since its invention. One of the greatest advantages of EVL over endoscopic injection sclerotherapy (EIS) is its versatile adaptability, particularly for high-risk populations such as elderly patients. Originally, the “Stiegmann-Goff Ligator Kit” (Bard Co., USA) used for the EVL procedure was equipped with a wire to remove the ligature bands from the endoscope. In Japan, the modified pneumo-activated EVL device (Sumitomo Bakelite Co. Ltd.) was invented and came into common use. These single-band ligators require an over-tube to ligate esophageal varices. However, we now use a multi-band ligator without an over-tube to perform ligations in rapid succession. This chapter contains an outline description of the multi-band ligator comparing with the single-band ligator.
