CASTILLO, Ofelia et al. Use of cyanoacrylate in the endoscopic therapy of gastric varices: experience in the National Hospital Edgardo Rebagliati Martins from 2006 to 2010. Rev. gastroenterol. Perú [online]. 2011, vol.31, n.3, pp.208-215. ISSN 1022-5129.

OBJECTIVE: To evaluate the therapeutic success of the injection of N-butyl-2-cyanoacrylate in the treatment of gastric varices. METHODS: Cross-sectional study included 33 patients with gastric varices who only received cyanoacrylate endoscopic therapy between 2006 and 2010. Intravariceally, cyanoacrylate was injected in a 1:1 dilution with lipiodol until the obliteration of varices. The therapeutic situation was: active bleeding, varices with stigmata of recent bleeding and secondary prophylaxis. Treatment success was evaluated according to hemostasis, recurrent bleeding and obliteration. RESULTS: Of the 33 patients, 3 (9.1%) were for active bleeding, 20 (60.6%) with stigmata of recent bleeding and 10 (30.3%) as secondary prophylaxis. Gastric varices were GOV2, 17 (51.5%); IGV1, 14 (42.4%); GOV1, 2 (6.1%). Hemostasis was achieved in 21 (91.3%) and in 2 (66.7%) of 3 patients with active bleeding. Five (15.6%) patients had recurrent bleeding and 2 of them used cyanoacrylate with successful hemostasis. Obliteration was achieved in 25 (75.8%). Four patients died and one for failure of control bleeding. A high severity of Child-Pugh classification was related to treatment endoscopic failure (p=0.034). The main complication was bleeding after the injection of cyanoacrylate. CONCLUSIONS: Our results support the use of cyanoacrylate in the treatment of gastric varices with few major complications.
