To report the results of endoscopic ultrasound-guided injection of coils with cyanoacrylate (CYA) using a less-expensive coil with an emphasis on the roles of Doppler and endosonographic varicealography (EV) in identifying the feeder vessel in gastric varix treatment. An observational, descriptive study with prospectively collected data. Patients with gastric varices (GV) were included and were treated by endoscopic ultrasound-guided injection of CYA and a less-expensive coil. Technical success, complete and immediate variceal obliteration, rebleeding, complication and survival rates were evaluated. Thirty patients with GV with a mean age of 62years (range: 44-76years) were treated. Median number of coils used was 2 (range: 1-3), and median volume of CYA was 1.8mL (1.2-2.4mL). Technical success rate was 100%. EV technical success was observed in 26/30 patients. Complete variceal obliteration was observed in 96.6% of patients, and immediate disappearance of the varix was observed in 24 (80%) patients. The complication rate was 6.7%. Endoscopic-ultrasound guidance for gastric varix treatment with the addition of EV and the use of a less-expensive coil is a safe and effective technique that results in the immediate disappearance of GV after targeting the feeding vessel.
