Transpancreatic biliary sphincterotomy (TPBS) is considered more effective than needle\u2010knife precutting owing to its wire\u2010guided technique, which may be suitable for nonexpert endoscopists; however, comparisons between nonexpert and expert endoscopists performing TPBS are not well documented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive patients who underwent TPBS between January 2010 and April 2024 were evaluated. Rates of successful biliary duct cannulation, time to TPBS and bile duct cannulation, and adverse events were compared between both groups. Logistic regression analysis was conducted to identify factors associated with successful bile duct cannulation using TBPS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study included 140 patients (77 and 63 in the nonexpert and expert groups, respectively).
