OBJECTIVE: To evaluate the therapeutic success of endoscopic therapy with N-butyl-2-cyanoacrylate and to determine the re- bleeding and mortality rates. MATERIALS AND METHODS: Prospective analytical observational study of 47 cases of patients with gastric varices who were treated with N-butyl-2-cyanoacrylate, using a 1: 1 mixture with lipiodol between 2013 and 2017 in a level III public hospital in Lima - Peru. The therapeutic indication was active hemorrhage, primary or secondary prophylaxis. RESULTS: Of the 47 patients, 5 (10.6%) had active hemorrhage, control was obtained in all cases, 24 (51.1%) had stigmas of recent bleeding during endoscopy. Secondary prophylaxis was performed in 16 (34%) patients and primary prophylaxis in 2 (4.7%). 59.6% required a single session with a total volume of cyanoacrylate (ml / patient) of 1.28 ± 0.44. The endoscopic finding was GOV-2 in 78.7% of the cases, IGV-1 in 12.8% and GOV-1 in 8.5%. Seven patients (14.8%) presented late re- bleeding, with successful new therapy in 6 of them, one dying due to therapy failure. Of the six (12.76%) patients who died in total, 5 (83.3%) were due to other causes. No adverse events related to the therapy were reported. No adverse events were reported. Variceal obturation was observed in 28 (59.5%) patients. CONCLUSIONS: Endoscopic management of gastric varices with cyanoacrylate is a safe and effective treatment, with low recurrence and mortality rates.
