We studied the changes in gastroesophageal reflux on occasions with or withoutnasogastric tube in 6 patients feeding via nasogastric tube and after perCutaneous endo-scopic gastrostomy(PEG)placement, using a radioisotopic method. The gastroesophagealreflux indices measured immediately after extraction of nasogastric tube were lover thanthe values under nasogastric tube placement in 3, patients. In 4 patients, the gastroeso-phageal reflux indices after PEG placement were lower than those before PEG placement, and the post-PEG values gore almost similar to those measurod immediately after extrac-tion of nasogastric tube. These results suggest that PEA may improve gastroesophagealreflux induced by nasogastric tube, but may not improve the native gastroesophagealreflug which was not caused by nasogastric tubes. The gastroesophageal reflux indicesmeasured immediately after extraction of nasogastric tube may predict the values afterPEG, and the method may contribute to the decision of indication for PEG.
