Abstract
The present disclosure is directed to an injectable composition in form of fluid gel and the use thereof to assist the tissues resection during endoscopic procedures in which it is injected in the tissue of interest to form a cushion for tissue separation. Aspects of the composition can include a gelling agent, a modifier, a salt and water. The composition can be prepared by mixing the gelling agent, modifier, at least one salt and water via continuous stirring to obtain fluid gel solutions, wherein modifier enables the said fluid gel composition to be injected into the submucosal layer of gastrointestinal tissues through endoscopic injection catheter and needle with significantly reduced injection pressure and generate a high and durable cushion for long-lasting tissue raise-up in the submucosal layer, for the application of injection assisted resection procedures.
