Enteral stents can be defined as stents which are deployed in the stomach, colon and the small bowel. Enteral stents are designed to treat malignant luminal obstruction of the gastrointestinal tract. Although their use is for palliation of malignant obstruction, they can also be used within the colon as a pre-operative modality. Enteral stents maintain the lumen of hollow organs, vessels, and ducts. For colonic stents, preoperative stenting allows a one-stage operation and avoidance of colostomy. In patients undergoing palliation of obstruction, self-expandable metal stents (SEMS) allow avoidance of surgery. Newer stent designs for both upper and lower gastrointestinal use are needed which are covered while still allowing delivery through the endoscope channel, and are associated with low migration rates.
Enteral Stents Market: Drivers and Restraints
Expanding use of stents in non-malignant applications, and the need for effective therapies that reduce the risk of complications, rising use of fully-covered, removable metal stents in gastrointestinal applications, technological innovations in stent technology with regards to stent design and delivery systems, movement towards the increasing use of minimally-invasive techniques augmented by rising patient demand and awareness are some of the drivers leading to the growth of enteral stents market. Although the current stent technologies provide mechanical support to the organ in which they are used, both short- and long-term complications still occur, resulting in poor clinical outcomes and endangering patient safety. Based on the shortcomings of the current stents, a newer generation of devices boasting innovative structures, durable metal alloys, biodegradable stent platforms, and bioactive coatings is in development. However unmet needs remain a challenge also adverse effects related to the products are likely to hinder the growth of the enteral stents market.
