The effect of percutaneous endoscopic gastrostomy on aspiration pneumonia of patients with dysphagia

Abstract

Objective To explore the preventive effect of percutaneous endoscopic gastrostomy (PEG) on aspiration pneumonia in patients with dysphagia. Methods The clinical data of 43 patients undertaking PEG was retrospectively collected and the incidence of aspiration pneumonia, microbiological examination of sputum and antibiotics use before and after PEG in all the patients were compared. Results After PEG, the incidence of aspiration pneumonia decreased significantly from 90.7% to 53.5% according to clinical diagnosis, from 70.4% to 18.5% according to the chest imaging. The use of β-lactamase inhibitor compound decreased significantly, but the detection rate of pseudomonas aeruginosa increased significantly compared with that before PEG. Conclusion PEG can decrease the incidence of aspiration and antibiotics use, and may increase the chances of pseudomonas aeruginosa colonization in the lower respiratory tract.
