SDBS placement significantly lowers the incidence of acute cholangitis to 6%, compared to 30% in non-stent patients.
In this study of 63 patients undergoing ERCP, complete stone clearance was achieved, with a 17.4% overall cholangitis incidence.
Retrospective analysis included categorized groups for SDBS placement, assessing cholangitis-related factors, and adverse events.
Absence of SDBS was an independent risk factor for cholangitis post-procedure, with an odds ratio of 6.09.
