There was good agreement in the severity of GERD before
PEG between reviewers (k Z 0.643; 95% confidence interval, 0294e0.992). The k value was 0.694 (95 % confidence
interval 0.547e0.841) for the severity of GERD after
PEG. Agreement of the Hill’s classification of gastroesophageal
valve had a k value of 0.6 (95% confidence interval,
0.193e1.0).shows the demographic characteristics of 47
patients receiving PEG. Before PEG, 21 (44.7%) of 47 NGTfeeding
patients had EE. The mean follow-up time was
45.7 months (range, 6e147 months). Erosive esophagitis
occurred in nine (19.1%) patients after PEG. The discontinuation
time of PPI before post-PEG evaluation of GERD
condition ranged from 2 weeks to 2 months. Table 2 lists
changes in the occurrence and severity of EE before and
after PEG. The occurrence rate (p < 0.01) and severity
(p < 0.05) of EE significantly improved after PEG, compared
to before PEG. Table 3 describes the risk factors for the
presence of EE after PEG. Only Hill’s classification of the
gastroesophageal valve was associated with the occurrence
of EE after the PEG operation (p < 0.01
