Percutaneous endoscopic gastrostomy (PEG) has become a widely used method for nutritional support, particularly in patients with advanced head and neck carcinomas. Since the method is easy and widely established it is necessary to assess possible complications, even rare ones. In this paper we report on two patients with vaccination metastasis following PEG insertion. Both patients had advanced squamous cell carcinoma of the head and neck or the upper esophagus. In three patients previous bougienage was performed, because of considerable stenosis of the pharynx and/or esophagus. Fast-growing metastases were found at the site of PEG insertion, with and without involvement of the gastric wall. In neither case was abdominal wall metastasis the cause of death. There is a small but definite risk of tumor seeding into the abdominal wall after PEG insertion for obstructive malignant tumors. The clinical impact of this finding, however, is still undefined and needs further investigation.
经皮内镜下胃造口术（PEG）已成为一种广泛应用于营养支持的方法，尤其是在晚期头颈癌患者中。由于该方法操作简便且广泛应用，因此有必要评估可能出现的并发症，即使是罕见的并发症。在本文中，我们报告了两例PEG置入术后发生接种转移的患者。两名患者均患有晚期头颈或上段食管癌鳞状细胞癌。三名患者因咽和/或食管严重狭窄，此前进行了探条扩张术。在PEG置入部位发现了快速生长的转移灶，胃壁有无受累情况。两例患者均非因腹壁转移而死亡。对于梗阻性恶性肿瘤患者，PEG置入术后存在肿瘤种植至腹壁的小但明确的风险。然而，这一发现的临床影响仍不明确，需要进一步研究。
