title: Risk factors for complications and mortality of percutaneous endoscopic gastrostomy: a multicenter, retrospective study.
abstract: BACKGROUND
  Percutaneous endoscopic gastrostomy (PEG) is performed to provide nutrition to patients with swallowing difficulties. A multicenter study was conducted to evaluate the predictors of complications and mortality after PEG placement.
  
  
  METHODS
  This study retrospectively analyzed patients who underwent initial PEG placement between January 2004 and December 2011 at seven tertiary hospitals in the Republic of Korea.
  
  
  RESULTS
  All 1,625 patients underwent PEG placement by the pull-string method. The median age of the patients was 66 years, and 1,108 of the patients were men. The median follow-up period was 254 days. The common indications were stroke (31.6%) and malignancy (18.9%). The complication rate was 13.2%. The prophylactic use of antibiotics (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.38-0.88; p = 0.010) reduced the PEG-related infection rate, but the actual usage rate was 81.1%. The use of anticoagulants (OR, 7.26; 95% CI, 2.23-23.68; p = 0.001) and the presence of diabetes mellitus (OR, 4.02; 95% CI, 1.49-10.87; p = 0.006) increased the risk of bleeding, but antiplatelet therapy did not. The procedural, 30-day, and overall mortality rates were 0.2, 2.4 and 14.0%, respectively. Serum albumin levels lower than 31.5 g/L (OR, 8.55; 95% CI, 3.11-23.45; p < 0.001) and C-reactive protein levels higher than 21.5 mg/L (OR, 3.01; 95% CI, 1.27-7.16; p = 0.012) increased the risk of 30-day mortality, and the patients who had both risk factors had a significantly shorter median survival time than those who did not (1,740 vs 3,181 days) (p < 0.001, log-rank).
  
  
  CONCLUSIONS
  The findings showed PEG to be a safe and feasible procedure, but the patient's nutritional and inflammatory status should be considered in predicting the outcomes of PEG placement.
