“…In terms of type of colonic stents, 3 meta-analyses have compared U-SEMS and C-SEMS, noting similar technical and clinical success, but U-SEMSs were associated with fewer overall AEs, including less tumor overgrowth, lower migration rates, longer patency, and fewer re-insertions, although at the cost of higher risk of tumor ingrowth [ 121 , 122 , 123 ]. The main complications included perforation, stent failure, stent migration, and stent re-obstruction [ 124 ]. Migration should be treated with stent replacement or SIS technique in the palliative setting, and early surgery in the bridge-to-surgery patients [ 125 ].…”
