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 62 years (range: 44-76 years) were treated. Median number of coils used was 2 (range: 1-3), and median volume of CYA was 1.8 mL (1.2-2.4 mL). 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.
报告使用较廉价的线圈进行内镜超声引导下氰基丙烯酸酯（CYA）注射治疗胃静脉曲张的结果，重点介绍多普勒和内镜超声静脉曲张造影（EV）在识别胃静脉曲张治疗中供血血管的作用。
这是一项前瞻性收集数据的观察性描述性研究。纳入胃静脉曲张（GV）患者，采用内镜超声引导下 CYA 和较廉价线圈注射治疗。评估技术成功率、完全和即刻静脉曲张闭塞、再出血、并发症和生存率。
30 例 GV 患者，平均年龄 62 岁（范围：44-76 岁）。使用的线圈中位数为 2 个（范围：1-3 个），使用的 CYA 中位数体积为 1.8 毫升（范围：1.2-2.4 毫升）。技术成功率为 100%。26/30 例患者 EV 技术成功。96.6%的患者完全闭塞静脉曲张，24 例（80%）患者即刻消失。并发症发生率为 6.7%。
在 EV 指导下，使用较廉价的线圈进行胃静脉曲张治疗是一种安全有效的技术，可在靶向供血血管后即刻消失 GV。
