A Risk Factor for Wound Infection after Percutaneous Endoscopic Gastrostomy: Decreased Performance Status / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) has been widely used for long term enteral nutrition. The most common complication is peristomal wound infection. The aim of this study is to investigate the risk factors for peristomal wound infection after PEG. METHODS: We reviewed the records of 55 patients who had undergone PEG placement at Kangnam St. Mary's hospital via the Pull-string technique. We analyzed the underlying disease, the performance status and the nutritional state of the patients to determine the risk factors for wound infection. RESULTS: Peristomal wound infection after PEG occurred in 20 (36.4%) of the 55 patients. Methicillin resistant Staphylococcus aureus (MRSA) was the most common isolated microorganism. On univariate analysis, the underlying CNS disease, non-malignant disease and a decreased performance status (ECOG 3, 4) were correlated with wound infection. On multivariate analysis, a decreased performance status was an independent risk factor for wound infection after PEG (p=0.007, OR=6.011, CI 1.64~22.09). CONCLUSIONS: A decreased performance status was an independent risk factor for peristomal wound infection after PEG.
