BACKGROUND/PURPOSE: Despite frequent use of percutaneous endoscopic gastrostomy ( @entity970 ) for enteral feeding, the relationship between it and @entity354 ( @entity354 ) remains an incompletely answered question. We conducted this study to compare the @entity354 between the same @entity1 fed with a nasogastric (NG) tube and later with a @entity970 tube. METHODS: We enrolled 15 @entity1 who had received NG tube feeding for > 6 months and were about to receive @entity970 tube insertion. We used Ponsky's pull method with 24 Fr feeding tubes. They received two @entity354 scans, one just before @entity970 tube insertion and another 1 week after insertion. We drew regions of interest of radioactivity in the esophagus and stomach manually. The ratios of radioactivity of the region of interest in the esophagus over the stomach ( @entity354 ratio) were calculated to evaluate the severity of @entity354 and compared. RESULTS: The @entity354 ratios of these @entity1 were all small and <3% except one that was 4.7% in one @entity1 before @entity970 tube insertion. There was a small but substantial decrease (65% risk reduction) in @entity354 ratio after @entity970 tube insertion. After arcsine transformation, the difference in the transformed data between @entity1 fed with an NG tube and after @entity970 tube insertion was significant (t= 2.46, p = 0.028), and was lower after @entity970 tube insertion. CONCLUSION: Our study demonstrates by scintigraphy a small but significant reduction of @entity354 after shifting from NG to @entity970 tube feeding.
