Introduction: Approximately 20% of cases of colorectal cancer are accompanied by acute colonic obstruction. While emergency colonic surgery is associated with high mortality and morbidity rates, placement of a self-expanding metal stent (SEMS) has been suggested as an alternative method. The SEMS placement can serve as either a definitive treatment in palliative cases or a bridge to surgery. Aim: To summarize the experience of our center in the treatment of malignant colonic obstruction using SEMS placement...

Biodegradable vascular scaffolds (BVS) are novel treatments for obstructive atherosclerotic cardiovascular disease that have been developed to overcome the limitations of traditional metallic drug-eluting stents (DES). The mechanical properties of bioabsorbable polymers used for the production of novel BVS are a key consideration for the clinical translation of this emerging technology. Herein, we describe the engineering of an in situ light-activated vascular scaffold (ILVS) comprised of a biodegradable citric acid-based elastomeric polymer, referred to as methacrylated poly-diol citrate (mPDC), and a diazeniumdiolate chitosan nitric oxide donor (chitoNO)...
