Abstract

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) has been widely performed for patients who require prolonged tube feeding support. A retrospective study was conducted to evaluate the complications of PEG and determine the predictors of wound infection.
METHODS
Medical records of 144 cases of PEG that was per- formed between January 1996 and June 2000 were reviewed to examine the types and frequency of complication, difference in wound infection rates according to age, sex, and underlying diseases. We also analyzed the effects of antibiotics prophylaxis on wound infection and the result of culture from wound infection site.
RESULTS
In 28 of 144 PEG cases (19.4%), several complications developed after procedure. Wound infection was the most common complication and occurred in 22 of 144 cases (15.3%) and Pseudomonas aeruginosa was the most common pathogenic microorganism. Other complications included bleeding from gastrostomy site, stomal leaks, and gastroesophageal reflux. There was no statistical difference in wound infection rates according to underlying diseases and antibiotics prophylaxis. However, wound infection developed more frequently in diabetes patients (P < 0.05). Old age and underlying diabetes were predictors for developing wound infection after PEG in multiple logistic regression analysis.
CONCLUSIONS
Old age and DM can be predictors of wound infection associated with PEG.
