Percutaneous endoscopic gastrostomy in children: influence on gastroesophageal reflux.

OBJECTIVE Few data exist in the literature about the relationship between percutaneous endoscopic gastrostomy (PEG) and gastroesophageal reflux (GER) in children, and the data that do exist are contradictory. The aim of the present study was to evaluate the effect of PEG on GER. METHODS Twenty children underwent PEG for enteral nutrition. They were 55 +/- 55 months old and weighed 13 +/- 10 kg. A pH study was performed before and after PEG without treatment when GER status was unknown (n = 10) or under treatment (n = 10) if previous GER was demonstrated. In these cases, the pH study was performed under the same treatment before and after PEG. RESULTS Six pH studies had abnormal results before PEG. After PEG, the GER of these 6 children significantly improved after the treatment was intensified (n = 50 or spontaneously normalized (n = 1). Results of 13 pH studies that were previously normal remained normal. Only one child with a normal reflux index before PEG had GER after it. For the 20 children, the mean reflux index did not change significantly after PEG (5.5% vs 5.6%). CONCLUSION Contrary to surgical gastrostomy, PEG does not worsen GER. Therefore, GER is not a contraindication to PEG.
