We evaluated the usefulness of newly modified FCSEMS (M\u2010FCSEMS) having 12\u00a0mm in diameter and anti\u2010migration feature to minimize stent migration compared with the conventional FCSEMS (C\u2010FCSEMS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Total 102 patients were enrolled between January 2015 and September 2017 in this prospective comparative study; 50 were allocated to the M\u2010FCSEMS group and 52 to the C\u2010FCSEMS group.

Endoscopic stent placement was technically successful in all patients. Stent migration occurred in 8.0% (4\/50) of the patients in the M\u2010FCSEMS group and 23.1% (12\/52) of those in the C\u2010FCSEMS group (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.036). The other adverse events, including stent\u2010related pancreatitis and cholecystitis did not significantly differ between the two groups (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.415). Stent occlusion occurred in 23.9% (11\/46) of the patients in the M\u2010FCSEMS group and 37.5% (15\/40) in the C\u2010FCSEMS group (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.171).
