Fully covered self-expandable metallic stents in benign biliary strictures: a multicenter study on efficacy and safety

Abstract

Despite the noteworthy migration rate, FCSEMSs should be considered effective for refractory benign biliary strictures. Further studies are needed to assess their role as a first approach in the management of BBS.

ENDOSCOPIC TREATMENT OF POST-LIVER TRANSPLANTATION ANASTOMOTIC BILIARY STRICTURE: systematic review andmeta-analysis

“…We found two retrospective comparative studies comparing plastic and metallic stents (6,15) . Tarantino et al (15) compared the outcomes of patients with failure of the multiple plastic stenting strategy sent to metallic stenting (salvage therapy group) with patients sent directly to metallic stenting as a first line treatment (first line treatment group).…”

“…Tarantino et al (15) compared the outcomes of patients with failure of the multiple plastic stenting strategy sent to metallic stenting (salvage therapy group) with patients sent directly to metallic stenting as a first line treatment (first line treatment group). The authors showed that the sustained clinical success rate was higher in the salvage therapy group when compared to the first line therapy group.…”

“…One study compared the results of fully covered selfexpandable metallic stents used as salvage therapy after failure of the treatment with plastic stents versus the use of SEMS as the 1st line therapy of ABS post-OLT (15) . The clinical success, the recurrence, the failure and migration rates were no different between the two groups.…”

“…Considering specifically ABS there are some treatment options including balloon dilation, the placement of multiple plastic stents (MPS) and the placement of self-expandable metal stents (6,9,10,15,18) . These modalities can be employed individually or in association.…”

Effectiveness of covered metallic stents of benign biliary stricture resolution

“…Compared with plastic stents, cSEMS showed a high rate of stricture resolution and fewer endoscopic procedures. Therefore, cSEMS was widely used and accepted for the treatment of benign biliary stricture (7,10). However, the endoscopic placement of stents to relieve biliary stricture should take into account the causes of biliary stricture, stricture resolution rate, stricture recurrence rate, stent migration, which may cause complications.…”
