Endoscopic injection sclerotherapy (EIS), in which a sclerosing agent is infused into esophageal varices, is advantageous in obstructing a blood‐supplying route; however, accurate intravascular infusion is technically difficult. To achieve accurate continuous intravascular infusion that does not depend on respiration or vomiting reflex, we developed an indwelling needle for esophageal varices. This indwelling needle facilitated intravascular puncture, as demonstrated for conventional puncture needles, and stabilized infusion of a sclerosing agent. Furthermore, EIS with ligation (EISL) prevented hemorrhage after the needle was removed. EISL with an indwelling needle may improve the treatment results.
