Relationship between esophageal lesions observed by endoscopy and nasogastric intubation: a study of 185 cases of percutaneous endoscopic gastrostomy

Percutaneous endoscopic gastrostomy (PEG) is a method widely used for long-term enteral nutrition in dysphagia. Mostly, it is preceded by nasogastric intubation (NI) for short-term enteral nutrition; endoscopic findings associated with NI are encountered during PEG. The purpose of this study was to discuss such findings and to delineate a relationship between these findings, especially esophageal lesions and the duration of NI. This study involved 185 individuals who had undergone PEG at Kyung Hee Medical Center from January 1999 to May 2002. The medical records were examined retrospectively. The dysfunction of the CNS comprised 98.4% of the causes of dysphagia. The duration of NI was 15.2 weeks on average, with median value of 8.7 weeks, indicating that PEG was performed relatively soon. Endoscopic findings revealed esophagitis in 63 cases, esophageal ulcers in 27 and active bleedings in another 10. The incidence of esophageal lesions was shown to be higher in subjects with duration of NI under 12 weeks than in those with duration over 12 weeks (p=0.032). PEG was carried out in many cases during the early stages of dysphagia, and NI-associated esophageal lesions appeared to be more prevalent within 12 weeks of NI duration. These results may be of help in deciding the timing of PEG.
