title: [Stents in the digestive tract: state of the art].
abstract: Stents are devices currently used for palliative and definitive treatment in cases of malignant obstructions of the digestive tract and nowadays can be used in benign cases like stenosis, fistulas or perforations. The progress made in the design and delivery systems of these prostheses have been of extraordinary benefit, which consequently are now considered as a minimally invasive treatment. The evolution of these prostheses allows patients not only a palliative treatment but also a possibility of curative option, due to antimitotic drug release (Idionine 125). In addition, the use of biodegradable materials in them, enable the reduction of the rate of complication, related with the number of procedures.
