Percutaneous endoscopic gastrostomy tubes are frequently colonized with fungal and bacterial organisms. This has not been previously reported. In our sample of 10 patients, nine percutaneous endoscopic gastrostomy tubes were colonized with fungi. This occurred as early as 1 week after placement. Candida tropicalis was isolated in five patients. It is hypothesized that a variety of fungi use components of the gastrostomy tube polymer, such as polymer additives, which contribute to the structural deterioration of the tube.
经皮内镜下胃造口管常被真菌和细菌定植。此前尚未有过相关报道。在我们的10例患者样本中，9根经皮内镜下胃造口管被真菌定植。这种情况最早在置管后1周就出现了。5例患者分离出热带念珠菌。据推测，多种真菌利用胃造口管聚合物的成分，如聚合物添加剂，这会导致管子的结构恶化。
