Background: Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiological gastrostomy (PRG) are commonly utilized to establish access to enteral nutrition. However, data comparing the outcomes of PEG vs. PRG are conflicting. Therefore, we aimed to conduct an updated systemic review and meta-analysis comparing PRG and PEG outcomes.

Methods: Medline, Embase, and Cochrane library databases were searched until February 24, 2023. Primary outcomes included 30-day mortality, tube leakage, tube dislodgement, perforation, and peritonitis. Secondary outcomes included bleeding, infectious complications, and aspiration pneumonia. All analyses were conducted using Comprehensive Meta-Analysis Software.

Results: The initial search revealed 872 studies. Of these, 43 of these studies met our inclusion criteria and were included in the final meta-analysis. Of 471,208 total patients, 194,399 received PRG and 276,809 received PEG. PRG was associated with higher odds of 30-day mortality when compared to PEG (odds ratio (OR): 1.205, 95% confidence interval (CI): 1.015 - 1.430, I2 = 55%). In addition, tube leakage and tube dislodgement were higher in the PRG group than in PEG (OR: 2.231, 95% CI: 1.184 - 4.2 and OR: 2.602, 95% CI: 1.911 - 3.541, respectively). Perforation, peritonitis, bleeding, and infectious complications were higher with PRG than PEG.

Conclusion: PEG is associated with lower 30-day mortality, tube leakage, and tube dislodgement rates than PRG.
