Title: The number of wire placement in the pancreatic duct and metal biliary stent as risk factors for post-endoscopic retrograde cholangiopancreatography pancreatitis. Author: Shin SH, So H, Cho S, Kim N, Baik GH, Lee SK, Park DH. Journal: J Gastroenterol Hepatol; 2020 Jul; 35(7):1201-1207. PubMed ID: 31830336. Abstract: BACKGROUND AND AIM: Many post-ERCP pancreatitis (PEP) risk factors, including pancreatic duct cannulation, have been identified; however, whether the number of repeated and unintentional wire placements (WPs) in the pancreatic duct during wire-guided cannulation affects PEP risk is unknown. We aimed to identify the effects of repeated WP in the pancreatic duct and other potential risk factors on PEP incidence. METHODS: We retrospectively analyzed 877 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP). We examined potential patient-related and procedure-related risk factors, and PEP incidence by univariable and multivariable logistic regression analyses. RESULTS: Thirty-four patients (3.9%) had PEP. Univariable analysis revealed younger age, malignant common bile duct or ampulla of Vater stricture, two or more episodes of WPs in the pancreatic duct, and metal biliary stent as risk factors for PEP. Following multivariable analysis, two or more episodes of WPs in the pancreatic duct and metal biliary stent remained in the final model. PEP did not increase significantly in case of a one episode of WP (4.0%) compared with no episode of WP in the pancreatic duct (2.7%). However, patients with two episodes of WPs had 8.0% incidence and three or more episodes of WPs had 14.3%. CONCLUSIONS: A WP in the pancreatic duct and a metal biliary stent were associated with increased PEP incidence in patients undergoing ERCP. As for the pancreatic duct wire cannulation, two or more WPs considerably increased PEP incidence. This suggests that preventive measures or alternative procedures might be considered in patients with such cases during and after ERCP.[Abstract] [Full Text] [Related] [New Search]
