Abstract

Abstract: Aims: We evaluated the feasibility, efficacy and safety of a novel technique of balloon-occluded retrograde transvenous obliteration (BRTO) assisted endoscopic Histoacryl (N-buthyl-2-cyanoacrylate) injection. Material and methods: A total with 11 patients were enrolled and analyzed in this single center, open-label, prospective study. Patients with high-risk gastric varices (defined as fundal varices, large GV (>5 mm), presence of a red spot, and Child-Pugh score C) and concurrent gastrorenal shunt underwent endoscopic Histoacryl injection while the gastrorenal shunt was temporarily occluded with an occlusion balloon. Feasibility, hemostatic effect, intra- and postoperative complications, and varices recurrence were evaluated. Results: All procedures were successfully done per protocol. Except for one patient who underwent rescue Histoacryl injection due to residual varices, single therapy was sufficient to eliminate gastric varices in ten patients. Intra-operative hemorrhage occurred in one case and was stopped after additional Histoacryl injection. One patient was confirmed to have treatment-related fungemia. No death or major complications occurred, including ectopic embolism, worsening of hepatic and renal function, etc. No recurrence of the varices was found during a median follow-up time (mean ± SD) of 228 ± 153 days. Conclusions: BRTO assisted endoscopic Histoacryl injection is effective and safe for patients with high-risk gastric varices and concurrent gastrorenal shunt.
