Background and study aims: Percutaneous endoscopic gastrostomy (PEG) is a procedure that provides long term enteral nutrition. To investigate the predictors of PEG-related complications and 30-day mortality rates and evaluate the indicators for deciding whether to recommend elective PEG insertions, we sought to determine the complications and early mortality rates of patients who underwent PEG.

Patients and methods: We performed a retrospective analysis of consecutive adult patients who had undergone PEG for the first time between October 2016 and January 2019. The predictors of complications and 30-day mortality were analyzed with receiver operating characteristic (ROC) and logistic regression analysis.

Results: This study included 309 patients. Patients were excluded from the study if they were < 18 years of age or there were missing data about them. Out of 253 patients, 33 (13%) had complications and 32 (12.6%) died within one month after PEG insertion. A higher C-reactive protein (CRP) to albumin ratio was the only independent factor predicting the complications (odds ratio (OR) : 3.17 ; 95% CI : 1.26-8.00 ; p = 0.014). The independent predictive factors for 30-day mortality after PEG placement included higher urea levels and higher CRP to albumin ratios (OR : 3.78 ; 95% CI : 1.41-10.17 ; p = 0.008) (OR : 6.67 ; 95% CI : 1.87- 23.75 ; p = 0.003). The only predictor for both complications and 30-day mortality was the CRP to albumin ratio.

Conclusions: When appropriate, the PEG procedure can provide a safe and effective method for enteral feeding. The CRP to albumin ratio can be used to predict complications and early mortality after PEG insertion. Because PEG is elective, higher CRP to albumin ratios can be helpful in deciding to select patients for the procedure.
