Background:To date,there is controversy regarding unilateral versus bilateral stent placement in patients with malignant hilar biliary strictures(MHBSs).The aim of this study was to compare the clinical outcomes and complications of unilateral and bilateral(stent-in-stent method)stent placements for these ***:We conducted a multicenter retrospective analysis of patients with inoperable MHBS who underwent endoscopic self-expandable metal stent(SEMS)placement from January 2009 to December *** groups classified according to the stent procedure method were compared for demographic,procedural,and postprocedure *** analysis for patency loss and overall survival was also ***:A total of 236 subjects were included.A superior technical success rate was found in the unilateral stent group(98.8%vs.82.5%,P<0.001),whereas the clinical success rate was higher in the bilateral group(85.7%vs.70.5%,P=0.028).There was no significant difference with respect to complications or patency loss,and the bilateral group had better overall survival(P<0.01).In the Cox proportional hazard model,MHBSs from lymph node compression were associated with a higher risk of death(HR=9.803,P=0.003).In contrast,bilateral SEMS insertion showed reduced postprocedural mortality(HR=0.316,P=0.001).Conclusions:Y-type stent-in-stent bilateral SEMSs are technically difficult but demonstrated more favorable overall survival for palliative bile drainage of inoperable MHBS patients compared to unilateral insertions.

In recent years,self-expandable metal stents(SEMSs)have been employed to treat benign gastrointestinal strictures secondary to several conditions:Acute diverticulitis,radiation colitis,inflammatory bowel disease(IBD),and postanastomotic leakages and *** applications include endometriosis and fistulas of the lower gastrointestinal *** it may be technically feasible to proceed to stenting in the aforementioned benign diseases of the lower gastrointestinal tract,the outcome has been reported to be *** fact,in some settings(such as complicated diverticulitis and postsurgical anastomotic strictures),stenting seems to have a limited evidence-based benefit as a bridge to surgery,while in other settings(such as endometriosis,IBD,radiation colitis,etc.),even society guidelines are not able to guide the endoscopist through decisional algorithms for SEMS *** aim of this narrative paper is to review the scientific evidence regarding the use of SEMSs in nonmalignant diseases of the lower gastrointestinal tract,both in adult and pediatric settings.
