We aimed to evaluate the safety and efficacy of fluoroscopically placed jejunal extension tubes (J-arm) in patients with existing gastrostomy tubes.
We conducted a retrospective review of 391 J-arm placements performed in 174 patients. Indications for jejunal nutrition were aspiration risk (35%), pancreatitis (17%), gastroparesis (13%), gastric outlet obstruction (12%), and other (23%). Technical success, complications, malfunctions, and patency were assessed. Percutaneous gastrostomy (PEG) tube location, J-arm course, and fluoroscopy time were correlated with success/failure. Failure was defined as inability to exit the stomach. Procedure-related complications were defined as adverse events related to tube placement occurring within seven days. Tube malfunctions and aspiration events were recorded and assessed.
Technical success was achieved in 91.9% (95% CI, 86.7%-95.2%) of new tubes versus 94.2% (95% CI, 86.7%-95.2%) of replacements (P = 0.373). Periprocedural complications occurred in three patients (0.8%). Malfunctions occurred in 197 patients (50%). Median tube patency was 103 days (95% CI, 71-134 days). No association was found between successful J-arm placement and gastric PEG tube position (P = 0.677), indication for jejunal nutrition (P = 0.349), J-arm trajectory in the stomach and incidence of malfunction (P = 0.365), risk of tube migration and PEG tube position (P = 0.173), or J-arm length (P = 0.987). A fluoroscopy time of 21.3 min was identified as a threshold for failure. Malfunctions occurred more often in tubes replaced after 90 days than in tubes replaced before 90 days (P < 0.001). A total of 42 aspiration events occurred (OR 6.4, P < 0.001, compared with nonmalfunctioning tubes).
Fluoroscopy-guided J-arm placement is safe for patients requiring jejunal nutrition. Tubes indwelling for longer than 90 days have higher rates of malfunction and aspiration.
我们旨在评估在已有胃造瘘管的患者中,透视引导下放置空肠延长管(J臂)的安全性和有效性。
我们对174例患者进行的391次J臂放置进行了回顾性研究。空肠营养的适应证包括误吸风险(35%)、胰腺炎(17%)、胃轻瘫(13%)、胃出口梗阻(12%)和其他(23%)。评估技术成功率、并发症、故障及通畅情况。经皮胃造瘘(PEG)管位置、J臂走行及透视时间与成功/失败相关。失败定义为无法穿出胃。与操作相关的并发症定义为置管后7天内发生的与置管相关的不良事件。记录并评估管道故障及误吸事件。
新置管的技术成功率为91.9%(95%CI,86.7%-95.2%),置换管的技术成功率为94.2%(95%CI,86.7%-95.2%)(P = 0.373)。围手术期并发症发生在3例患者中(0.8%)。197例患者(50%)出现故障。管道通畅的中位时间为103天(95%CI,71 - 134天)。J臂放置成功与胃PEG管位置(P = 0.677)、空肠营养适应证(P = 0.349)、J臂在胃内的走行与故障发生率(P = 0.365)、管道移位风险与PEG管位置(P = 0.173)或J臂长度(P = 0.987)之间均未发现关联。确定透视时间21.3分钟为失败阈值。90天后置换的管道比90天前置换的管道故障发生率更高(P < 0.001)。共发生42次误吸事件(与无故障管道相比,OR 6.4,P < 0.001)。
透视引导下放置J臂对需要空肠营养的患者是安全的。留置超过90天的管道故障和误吸发生率更高。
