“…The refluxed material together with bacterial adhesion was believed to be the primary cause of plastic stent occlusion. [14][15][16] In 2007, Dua et al 14 reported a modified plastic biliary stent with an antireflux function. In their study, a 4-cm long windsock-shaped valve was attached to the distal end of the stent in the duodenum.…”

“…However, one possible issue with this practice is that in providing a barrier to reflux, one could also introduce a physical barrier to the desired drainage properties. A randomized controlled trial comparing 10 Fr biliary PS with or without antireflux valves in 48 patients demonstrated (although underpowered) that antireflux valves increased biliary plastic stent patency from 101 to 145 days [71]. This principle has been extended to SEMS (independently of their covering), and these are referred to as antireflux metal stents (ARMS).…”

Endoscopic insertion of a self-expanding metal stent (SEMS) through a malignant common bile duct stricture is the first line of palliation for malignant jaundice. Patency of these stents remains a major concern. SEMS dysfunction can result from tumor ingrowth, overgrowth and/or clogging. Initial SEMS modifications involved covering the central part of the stent in order to reduce ingrowth and ultimately increase patency. Fully covered stents became available shortly after reports of their use in human patients. The potential removability and radial strength of SEMS have led to evaluation of their use in new indications including benign biliary strictures, post sphincterotomy bleeding and perforation. Other aspects of development include the addition of features such as anti-reflux valves, drug elution and spontaneous biodegradability. These aspects and their clinical implications are reviewed and discussed.

“…Despite being a plastic stent, it was found to have approximately 1.5 times longer stent patency period, but follow-up studies have not been performed yet 21. For the same purpose, studies on SEMS with antireflux valve have been conducted (Figs.…”

Biliary stents are widely used not only for palliative treatment of malignant biliary obstruction but also for benign biliary diseases. Each plastic stent or self-expandable metal stent (SEMS) has its own advantages, and a proper stent should be selected carefully for individual condition. To compensate and overcome several drawbacks of SEMS, functional self-expandable metal stent (FSEMS) has been developed with much progress so far. This article looks into the outcomes and defects of each stent type for benign biliary stricture and describes newly introduced FSEMSs according to their functional categories.
