We have reported a 16.0 mm long new type of instrument with the inner diameter of inner cylinder of 10.3 mm for endoscopic variceal ligation which could shoot 3 elastic O bands continuously in short period of time without removing the endoscope. The suction volume of new instrument is larger than that of the Stiegmann's ligator. We performed endoscopic variceal ligation (EVL) in 17 cases of the esophageal varix and 8 cases of the solitary gastric varix. EVL was performed as prophylaxis as all the cases. The esophageal varices were eliminated in all the cases after ulcer formation. The procedure was performed one time in 15 cases and two times in the remaining 2 cases. Three patients died one to hepatic failure during the follow-up period between 4 and 16 months. Six and twelve months cumulative recurrence rates were 30% and 48% respectively. On the other hand all the gastric varices disappeared after one sitting of the treatment. There was one variceal recurrence during the follow-up period. Computed tomography and/or arterioportography performed before had showed patent gastro-renal shunt in five cases. No change in the shunt was observed after the treatment. No serious complications due to EVL was encountered in all the cases. Therefore, it is thought that this method can be used for the treatment of not only esophageal varices but also gastric varices.
