esophagitis, ESCC
ESOPHAGITIS
Pretreatment PEG is a safe and effective approach for long‐term enteral nutrition in unresectable locally advanced ESCC patients treated with CCRT. The PEG group had better nutritional status, less incidence of severe esophagitis, and higher response to CCRT than the NTF and ONS groups. Compare with NTF and ONS groups, pretreatment of PEG can be cost‐effective because of significant clinical benefits.
