Background: Combination treatment of a fully-covered self-expandable metal stent (FCSEMS) and plastic stents (PSs) can minimize the risk of adverse events for benign biliary strictures (BBSs).
Methods: We retrospectively reviewed patients who underwent a FCSEMS placement for BBSs between October 2016 and November 2024. Side-by-side PS ("Rescue PS") was used to prevent segmental cholangitis. Stent-in-stent PS ("Core PS") was employed to avoid biliary kinking.
Results: Among 108 patients, 85 (78.7%) cases necessitated a combination treatment. The etiology of BBS were hepaticojejunostomy anastomotic strictures in 55.3%, post-living donor liver transplantation biliary strictures in 27.1%, post-cholecystectomy strictures in 9.4%, and post-liver resection strictures in 3.5%. Treatment naive cases comprised 36.5%. Technical success was 100%, and rescue and core PSs were used in 91.8% and 30.6%, respectively. The adverse event rate was 10.0%. Two patients experienced liver abscesses due to migration of rescue PS. Stent-free was achieved in 85.9% after 95 days.
Conclusions: A combination of FCSEMS and PSs was feasible for the biliary drainage of BBSs.
