Percutaneous endoscopic gastrostomy (PEG) has become a mainstay in providing enteral access for patients with obstructive oropharyngeal and esophageal tumors. PEG tube placement is considered safe, and complications are infrequent. One complication, although rare, that is being increasingly reported is the metastasis of cancer at PEG stomata. Herein, a case of metastasis of an esophageal cancer at a PEG stoma is described. Although it has been previously suggested that cancer metastasis is due to direct seeding of the stoma, an analysis of the literature suggests that this phenomenon is related to the hematogenous or lymphatic spread of cancer cells to a susceptible site.
经皮内镜下胃造口术（PEG）已成为为患有阻塞性口咽和食管肿瘤的患者提供肠内通路的主要手段。PEG管置入被认为是安全的，并发症并不常见。一种并发症，尽管罕见，但报告越来越多，即癌症在PEG造口处转移。本文描述了一例食管癌在PEG造口处转移的病例。尽管此前有人认为癌症转移是由于造口的直接播种，但文献分析表明，这种现象与癌细胞通过血行或淋巴扩散到易感部位有关。
