At present, there is no consensus on whether gastrojejunostomy tubes should be routinely changed and if so, on what timescale.
We describe our 5-year experience following the 2018 introduction of an interventional radiology lead service of four to six monthly elective changes. We focused on the impact this had on the number and length of hospital admissions, and radiation dose.
Retrospective review of gastrojejunostomy tube exchanges performed from 2011-2022 in a single centre.
Over 11 years, 89 gastrojejunostomy tube exchanges were performed in ten patients. Following the introduction of the interventional radiology-led elective service in 2018, 50 gastrojejunostomy tube exchanges were done electively vs 25 done as emergencies. On average, gastrojejunostomy tubes were replaced every 5.6 months (elective 6.4 months, emergency 3.3 months). The median was 4 months. The most cited reasons for an emergency replacement were a malfunctioning tube or displaced tube. General anaesthetic was required for 61 exchanges. Admission time was shorter for elective exchanges (1.2 days vs 3.1 days). There was no significant difference in the average dose area product for elective vs emergency procedures.
Our results suggest that an optimal time for gastrojejunostomy tube replacement is 4 months. Elective replacement of gastrojejunostomy tubes results in a reduced number and length of admissions.
目前，对于是否应定期更换胃空肠造口管，如果需要更换，更换的时间间隔是多久，尚无共识。
我们描述了自2018年引入介入放射学主导的服务，每四至六个月进行一次选择性更换胃空肠造口管后的五年经验。我们重点关注这对住院次数、住院时长以及辐射剂量的影响。
对2011年至2022年在单一中心进行的胃空肠造口管更换进行回顾性分析。
在11年中，对10名患者进行了89次胃空肠造口管更换。2018年引入介入放射学主导的选择性服务后，进行了50次选择性胃空肠造口管更换，25次为急诊更换。胃空肠造口管平均每5.6个月更换一次（选择性更换为6.4个月，急诊更换为3.3个月）。中位数为4个月。急诊更换最常见的原因是造口管故障或移位。61次更换需要全身麻醉。选择性更换的住院时间较短（1.2天对3.1天）。选择性手术与急诊手术的平均剂量面积乘积无显著差异。
我们的结果表明，胃空肠造口管更换的最佳时间为4个月。选择性更换胃空肠造口管可减少住院次数和住院时长。
