Preoperative Inflammatory Markers as Predictors of Post-ERCP Pancreatitis: A Retrospective Cohort Study

Elevated preoperative NLR and CRP levels, together with pancreatic duct cannulation, were independently associated with an increased risk of post-ERCP pancreatitis. Although these inflammatory markers demonstrated statistically significant associations, their predictive strength was modest. Therefore, NLR and CRP should be interpreted as supportive parameters rather than standalone predictors and may contribute to pre-procedural risk stratification when integrated with established clinical and procedural risk factors. Further prospective, multicenter studies are warranted to validate these findings and clarify their role in clinical practice.
