“…Complications occurred at a lower rate in this study (5.9%) compared with previous studies with endoscopic SIS placement with LCD stents (7.0%-29.0%) (12,13,16,18,28) or percutaneous conventional opencell and partially covered large cell or covered stents placement (7.7%-33.3%) (11,(20)(21)(22)(23)(24)(25)(26).…”

“…The median stent patency and stent occlusion rate in our study (179 days and 35.6%, respectively) showed comparable outcomes to those reported by the aforementioned studies applying an endoscopic method using LCD stents (105-202 days and 42.0%-63.2%, respectively) (12,13,15,16,18,28), open-weave, crosswired stents (150-253 days and 6.0%-44.1%, respectively) (14,16,17,(29)(30)(31), or a percutaneous method with conventional open-cell and partially covered large cell or covered stents (75-330 days and 17.5%-48.4%, respectively) (11,(20)(21)(22)(23)(24)(25)(26). The differences in the definitions of the stent patency period do have to be taken into account.…”

“…In addition, successful internal drainage (88.2%) was obtained in the majority of patients without major complications. Several previous studies (11,(20)(21)(22)(23)(24)(25)(26) investigated the technical outcomes of percutaneous metallic stent placement in patients with MHBO. Reported technical success and successful internal drainage rates were 93.0%-100.0% and 87.5%-100.0%, respectively.…”

Background To overcome the technical difficulty of bilateral stent-in-stent placement, large cell-type biliary stents have been developed. However, most of the studies using large cell-type stents were conducted with endoscopic method. Purpose To evaluate the efficacy and safety of percutaneous stent placement with a stent-in-stent method using large cell-type stents in patients with malignant hilar biliary obstruction. Material and Methods From December 2015 and October 2018, 51 patients with malignant hilar biliary obstruction were retrospectively studied. All of the patients underwent bilateral (n=46) or unilateral (n=5) stenting in a T, Y, or X configuration with a stent-in-stent method using large cell-type stents. Technical success, complications, successful internal drainage, stent patency, and patient survival were analyzed. Results A total of 118 stents were successfully placed in 51 patients (100.0%). Three patients had minor complications with self-limiting hemobilia. Major complications were not observed in any patient. Successful internal drainage was achieved in 45 patients (88.2%). Clinical follow-up information until death or the end of the study was available for 50 of 51 patients. The median patient survival was 285.5 days (95% confidence interval [CI] 197–374). Stent dysfunction occurred in 16 patients (35.6%) due to tumor ingrowth (n=9) or tumor ingrowth combined with biliary sludge (n=7) among the patients who achieved successful internal drainage. Median stent patency was 179 days (95% CI 104–271). Conclusion Percutaneous stent-in-stent placement with large cell-type stents is technically feasible and safe, and can be an effective technique in patients with malignant hilar biliary obstruction.
