BACKGROUND: Emergency endoscopic injection sclerotherapy (EIS) has been applied to the initial treatment of gastric variceal bleeding and various methods have been attempted. METHODS: Emergency EIS was performed on 38 patients with gastric variceal bleeding using either the ethanolamine oleate (EO) method or n-butyl-2-cyanoacrylate (Histoacryl) method and the outcome was compared. RESULTS: Complete haemostasis was defined as continuous haemostasis lasting for 14 days or more. Complete haemostasis was achieved in 52.4% of patients in the EO method versus 100% of those treated with the Histoacryl method, a significant difference, suggesting that the Histoacryl method was superior for achieving haemostasis in an emergency. The cumulative non-bleeding rate was also significantly higher in patients treated with Histoacryl, indicating the durability of haemostasis. There were no serious complications in patients who received either method of sclerotherapy. Post-EIS surgery was required in 42.8% of patients treated with EO, while no surgery was required in those treated with Histoacryl, supporting the greater haemostatic effect of Histoacryl. Although there was no significant difference in the cumulative survival rates of patients treated by these two methods, death from haemorrhage was avoided by using Histoacryl. CONCLUSIONS: Based on these results, the Histoacryl method is thought to be the initial treatment of choice for gastric variceal bleeding, because it achieved superior haemostasis compared with EO and death by haemorrhage was avoided.
