Prospective evaluation of malignant cell seeding after percutaneous endoscopic gastrostomy in patients with oropharyngeal/esophageal cancers

Abstract

This study showed that malignant cells were present in 22.5 % of patients immediately after pull-through PEG placement; local metastases were verified at follow-up in 9.4 %, all of which were from esophageal squamous cell carcinoma. This risk is particularly high in the older age group and in patients with higher tumor stages. Therefore, pull-through PEG placement should be avoided in these patients and direct access PEG favored instead.
