Severe hyperplastic tissue stenosis of a novel biodegradable esophageal stent and subsequent successful management with high-pressure balloon dilation

Biodegradable polydioxanone stents: a new option for therapy-resistant anastomotic strictures of the colon

“…Mucosal hyperplasia resulting in re-obstruction after oesophageal BD stenting has been described [20,21], both cases responded well to a single balloon dilatation and resolved completely after stent dissolution. Both reports are fairly critical of BD stents on the basis of the mucosal reaction; however the treatment resulted in long-term patency of strictures that had failed to respond to conventional therapy.…”

Manejo endoscópico de las estenosis luminales en la enfermedad inflamatoria intestinal

“…La implantación intestinal de las prótesis biodegradables es técnicamente posible y relativamente simple; sin embargo existen algunos aspectos mejorables, como la reacción mucosa hiperplásica y la tasa de migración. En 2 trabajos se ha descrito una reacción mucosa hiperplásica después de la inserción de estas prótesis en esófago en el 3% de los pacientes 56,57 .…”

Drug-eluting/biodegradable stents

“…Case series have described initial experience with the SX-ELLA-BD stent for treatment of a variety of esophageal strictures, including caustic, 10-12 peptic, 10,13-14 malignant, [13][14][15] anastomotic, 10,15-16 and radiation-induced strictures 10 as well as achalasia. 13 Clinical responses and outcomes were varied.…”

“…13 Clinical responses and outcomes were varied. In the largest cohort of patients with refractory benign esophageal strictures, 21 patients who had required an average of 2.2 endoscopic dilations per month underwent insertion of 25-mm SC-ELLA-BD stents.…”
