OBJECTIVES: Precut sphincterotomy is often performed when bile duct cannulation is difficult; however, the former has a higher risk of complications than conventional methods. Early precut reduces the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). This study aimed to determine the appropriate timing for precut sphincterotomy to minimize the incidence of PEP.
METHODS: This retrospective study analyzed 320 patients who underwent precut sphincterotomy during their first endoscopic retrograde cholangiopancreatography at a single center. The optimal precut timing was identified using receiver operating characteristic analysis. Patients were divided into an optimized precut group (≤12 min, n = 198) and a delayed group (>12 min, n = 122). The incidence and risk factors of PEP were evaluated using multivariate analyses.
RESULTS: Receiver operating characteristic analysis identified 12.5 min as the optimal cutoff for transitioning to precut sphincterotomy (area under the curve, 0.613; sensitivity, 61.5%; specificity, 63.9%). The incidence of PEP was significantly lower in the optimized precut group than in the delayed precut group (5.1% vs. 13.1%, p = 0.02). Multivariate analysis identified delayed precut timing (odds ratio [OR], 3.134; p = 0.04) and the absence of endoscopic pancreatic stenting (OR, 0.284; p = 0.01) as independent risk factors for PEP.
CONCLUSION: Precut sphincterotomy within 12.5 min of a cannulation attempt reduces the risk of PEP while maintaining procedural safety. Additionally, endoscopic pancreatic stenting can reduce PEP, even in precut scenarios.
