Percutaneous gastrostomy, utilizing a dedicated catheterization kit, with a combination of ultrasonographic (US) and fluoroscopic guidance, was carried out in 27 patients. The main indication for gastrostomy was the need for nutritional support in malignant esophageal stricture. After distending the stomach with water via a nasogastric tube, the gastric antrum was punctured under US guidance and a guide wire was inserted, followed by fluoroscopically guided tract dilatation and insertion of a 2.5-mm Cope-loop catheter. In all patients but one (96%) the procedure was successfully completed in one or 2 attempts. Two complications occurred: one case of a small subcutaneous abscess near the puncture site, and one late incident of dislodgement of a catheter without string-loop fixation, which had been inserted at a catheter exchange after 6 weeks. Percutaneous gastrostomy guided by US and fluoroscopy is a safe and efficacious alternative to endoscopic and surgical gastrostomy.
27例患者采用专用导管套件，在超声（US）和荧光透视引导下进行了经皮胃造口术。胃造口术的主要指征是恶性食管狭窄需要营养支持。经鼻胃管向胃内注水使胃扩张后，在超声引导下穿刺胃窦并插入导丝，随后在荧光透视引导下扩张通道并插入一根2.5毫米的Cope环导管。除1例患者外（96%），所有患者均在1次或2次尝试中成功完成手术。发生了2例并发症：1例穿刺部位附近出现小的皮下脓肿，1例在6周后更换导管时插入的未带线环固定的导管出现晚期移位。超声和荧光透视引导下的经皮胃造口术是内镜和外科胃造口术的一种安全有效的替代方法。
