Schematic image of the application of thermoresponsive hydrogels as a submucosal cushion for endoscopic submucosal dissection (ESD): (a,b) injection of thermoresponsive hydrogels into the submucosal layer for mucosal elevation, (c,d) circumferential resection by cutting open via an insulation-tripped (IT) knife, and (e,f) suction of the gel under the mucosa and resection of lesion en bloc. Reprinted from [54] Acta Biomaterialia, 10, Lin Yu et al., Poly(lactic acid-co-glycolic acid)–poly(ethylene glycol)–poly(lactic acid-co-glycolic acid) thermogel as a novel submucosal cushion for endoscopic submucosal dissection, 1251–1258, Copyright (2013), with permission from Elsevier.
