However, migration is a significant problem, which requires prevention. The novel multi\u2010hole fully CSEMS (MHSEMS), which features multiple small holes on the covered membrane, is expected to prevent migration. This study aimed to evaluate the efficacy and safety of MHSEMS for MDBO.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This multicenter retrospective cohort study included 111 patients with MDBO who underwent MHSEMS placement between September 2022 and August 2023.

RBO included stent migration in 1.9%, stent occlusion in 11.7% (including ingrowth in 5.7%, biliary debris in 2.9%, hemobilia in 1.9%, and food impaction in 1.0%), and nonocclusion cholangitis (requiring biliary drainage) in 5.7%. Non\u2010RBO AEs included post\u2010endoscopic retrograde cholangiopancreatography pancreatitis in 11.7%, cholecystitis in 2.7%, and nonocclusion cholangitis in 2.7%.
