This research aims to assess the effectiveness and safety of various biliary cannulation techniques post-unintentional pancreatic duct access.
Conducted a retrospective analysis on 228 consecutive patients undergoing ERCP.
Divided patients into four groups based on cannulation methods.
Compared success rates of biliary cannulation and incidence of post-ERCP pancreatitis among groups.
Analyzed characteristics and outcomes statistically.
Biliary cannulation success rates varied from 88.60% to 97.10% across groups.
Post-ERCP pancreatitis incidence ranged from 0% to 27.50%, indicating significant variation.
Severe pancreatitis was notably higher in the TPS group compared to others.
High migration rate of pancreatic duct stents, particularly with trimmed wings.
