Popis: Background Peristomal wound infection is a common complication in patients receiving percutaneous endoscopic gastrostomy (PEG). The main reason for peristomal infection might be the oral microbes coating the gastrostomy tube during implantation. Povidone-iodine solution can be applied for skin and oral decontamination. We designed a randomized controlled trial to test the effectiveness of a Betadine® (povidone-iodine) coated gastrostomy tube to reduce peristomal infection after percutaneous endoscopic gastrostomy. Methods A total of 50 patients were randomized to Betadine and control groups (25 patients in each group) from April 2014 to August 2021 at a tertiary medical center. All patients received the pull method for PEG implantation using a 24-french gastrostomy tube. The primary endpoint was peristomal wound infection rate 2 weeks after the procedure. Results Changes in Neutrophil/Lymphocyte ratio (N/L ratio) and C-Reative protein (Delta CRP) at 24 h after PEG were higher in the control group than in the Betadine group (N/L ratio, 3.1 vs. 1.2, p = 0.047; CRP, 2.68 vs.1.16, p = 0.009). The two groups did not differ in post-PEG fever, peristomal infection, pneumonia, or all-cause infection. Delta CRP could predict peristomal infection and all-cause infection within 2 weeks (AUROC 0.712 vs. 0.748; p = 0.039 vs. 0.008). The best cut-off-point of Delta CRP for the diagnosis of peristomal wound infection was 3 mg/dl. Conclusion The betadine coating gastrostomy tube method could not reduce peristomal infection after percutaneous endoscopic gastrostomy. CRP elevation of less than 3 mg/dl may be used to exclude the potential peristomal wound infection. Trial registration NCT04249570 (https://clinicaltrials.gov/ct2/show/NCT04249570).
