We report trial of IOG between 5 years from April，2000 to March，2005 in 56 beds of our long term care ward and compare IOG with PEG (Percutaneous Endoscopic Gastrostomy)．We do not perform continuous nasogastric tube feeding (CNG) at our hospital in principle．In our hospital among these 5 years IOG was used to feed 43 dysphagic patients and PEG was used to 33 dysphagic patients as tube feeding．Seven (16.3％) of 43 patients who received IOG were able to eat orally three times a day and two patients were able to eat orally two times a day and three patients were able to eat once a day using IOG together．Only two patients (6.1％) who received PEG were able to eat orally three times a day and only one patient were able to eat two times a day and only one patient were able to eat once a day．The ratio to be able to eat orally is significantly higher in patients who received IOG than patients who received PEG．The ratio of MRSA positive in sputum is 39.5％ in IOG group and 51.5％ in the PEG group．It is slightly high in PEG，but there is not significant difference．Among these 5 years，17 patients (39.5％) died in the IOG group and 22 patients (66.7％) died in the PEG group．Mortality of the PEG group is significantly higher than that of IOG group．6 patients died by aspiration pneumonia in the IOG group，however，13 patients died by aspiration pneumonia in the PEG group．The mortality caused by pneumonia is significantly higher in the PEG group (39.4％) than in the IOG group (14.0％)．If we exclude pneumonia as the cause of death，mortality becomes approximately same in both group．IOG is a safe and useful method in comparison with PEG．PEG is placed easily now．IOG is the tube feeding that we should try once by all means before PEG．
