...The safety of the procedure in association with reasonable clinical success in a group of patients that is very difficult to manage makes temporary stent placement an appealing option ... the temporary placements of biodegradable stents were associated with clinical success in 1/3 of our patients...

...21 patients were enrolled in the study ... the biodegradable stent showed a favourable risk / benefit ratio, achieving complete relief of dysphagia in nearly 50% of RBES patients without the occurrence of major complications. The use of this stent may be a valuable alternative to repeat endoscopic dilation...

On the page 396 you can find the description of degradable stents. This article does not mention clinical efficiency and safety of the BD stent. However there are already numerous publications giving this evidence.
...Biodegradable stents have the potential to allow treatment of benign disease without the need for additional procedures to remove them. One such stent is the SX-ELLA (ELLA-CS, Hradec Králové, Czech Republic), designed for the treatment of benign strictures and of achalasia refractory to other therapies...

Pages 159-162 show general information about biodegradable stents. Later in the text a successful pediatric case is described. The pediatric biodegradable stent is a subject of ongoing research and further development.
...A 10 year-old healthy boy with normal psychomotor development ingested several full swallows of a drain cleaner by accident... A control endoscopy after 2 weeks showed a developing stenosis at the mid-esophagus about 2cm long... About 12 weeks after insertion, the stent had degraded about 50%. At that time, the esophageal mucosa had healed... Gastric pull-up or colonic interposition was avoided. The child now has normal eating habits...

On the pages 61 and 62 there are characteristics of different types of self-expanding plastic stents. BD Stent is mentioned as the only commercially available biodegradable stent. More detailed description is on the pages 83 and 84.
...In 2008, a biodegradable (BD) SX-ELLA stent was introduced. The stent is manufactured from woven polydioxanone monofilament, which degrades by random hydrolysis accelerated by a low ambient pH. Stent integrity and radial force are maintained for 6-8 weeks following deployment and its disintegration usually occurs by 11-12 weeks post deployment. The degradation products are not harmful; the stent material is partly absorbed and partly travels through the gastrointestinal tract...
