To evaluate the effectiveness and safety of percutaneous radiologic gastrostomy (PRG) under ultrasonographic (US) and fluoroscopic guidance using a simplified gastropexy technique.
One hundred and fifty-four (154) patients (mean age 73, range 22-93 years) were referred for PRG. Indication for PRG was neurologic disease, head/neck cancer, and other disease in 73%, 15%, and 12%, respectively. Initially, the stomach was filled with 300-500 cm3 of tap water via a nasogastric tube. The fluid-filled stomach was punctured under US guidance. A guidewire and a single T-fastener were introduced. Under fluoroscopic guidance, the tract was dilated over the guidewire until a 16F dilator with a peel-away sheath could be introduced. During dilatation, the external suture string to the T-fastener was held tight to fixate the gastric wall. A 14F balloon-retained gastrostomy tube was introduced and inflated. The T-fastener was then released, and the gastrostomy tube was retracted gently to affix the gastric wall to the abdominal wall (tube gastropexy). Technical success was assured by aspiration of gastric fluid and fluoroscopically by injection of a water-soluble contrast medium.
The primary technical success rate was 98%. At 30-day follow-up, 3.2% had major complications and 14% minor complications. Three patients (1.9%) died of complications related to the procedure. Thirteen cases (8%) of simple tube displacement without other complications occurred.
PRG guided by US and fluoroscopy is a relatively safe technique with a high success rate, provided the stomach can be properly distended with fluid. However, tube gastropexy alone does not seem to protect against early dislodgement.
评估在超声(US)和荧光镜引导下使用简化胃固定技术进行经皮放射学胃造口术(PRG)的有效性和安全性。
154例患者(平均年龄73岁,范围22 - 93岁)接受PRG治疗。PRG的适应证分别为神经系统疾病、头颈部癌和其他疾病,各占73%、15%和12%。最初,通过鼻胃管向胃内注入300 - 500 cm³的自来水。在超声引导下穿刺充满液体的胃。引入导丝和单个T形紧固件。在荧光镜引导下,沿导丝扩张通道,直至可引入带有可剥离鞘的16F扩张器。扩张过程中,将T形紧固件的外部缝合线拉紧以固定胃壁。引入14F球囊保留胃造口管并充气。然后松开T形紧固件,轻轻回撤胃造口管以将胃壁固定于腹壁(管胃固定术)。通过抽吸胃液和荧光镜下注射水溶性造影剂确保技术成功。
主要技术成功率为98%。在30天随访时,3.2%发生严重并发症,14%发生轻微并发症。3例患者(1.9%)死于与手术相关的并发症。发生13例(8%)单纯导管移位且无其他并发症。
在超声和荧光镜引导下的PRG是一种相对安全且成功率高的技术,前提是胃能够用液体适当扩张。然而,单纯的管胃固定术似乎不能防止早期移位。
