BACKGROUND: Cyanoacrylate injection is highly effective and is regarded as the treatment of choice in bleeding gastric varices in Europe, but intravenous injection of cyanoacrylate is not allowed in the USA and Japan because it may cause embolisms in other organs. Accordingly, we developed a new endoscopic combined treatment of endoscopic management of gastric varices using a detachable snare (EVLs) and simultaneous endoscopic sclerotherapy and O-ring ligation (EISL) (i.e. EVLs + EISL), and we prospectively evaluated its efficacy and safety. METHODS: Gastric varices were ligated with the loop of a detachable snare that opened to a diameter of 4 cm (EVLs). Then the residual varices around the ligated portion were sclerosed by ethanolamine oleate and the injected vessel was ligated using a pneumo-activated EVL device (EISL). The EVLs + EISL was performed in 35 patients: on an emergency basis in eight patients, on an elective basis in six patients and as primary prophylaxis in 21 patients. Liver function was classified as Child-Pugh class A in 12 patients, class B in 12 patients and class C in 11 patients. RESULTS: Endoscopic disappearance of gastric varices was obtained in 97.1% of the patients and they regressed in all patients. Haemostasis was achieved in all eight emergency cases. The 2-year cumulative non-recurrence rate was 85%, the 2-year cumulative non-bleeding rate was 92% and the 2-year cumulative survival was 80%. No patients died of bleeding from gastric varices. There were no serious short-term complications, such as haemorrhage, gastro-oesophageal perforation, ileus, or renal impairment. CONCLUSION: Combined EVLs + EISL appears to be a useful treatment for gastric varices due to its safety and good clinical outcome.
