Chronological changes of mucosal elevation after submucosal injection of various solutions (N/S; normal saline, 10DW; 10% glucose solution, SA; 1% sodium alginate solution, SH; 0.5% sodium hyaluronate solution). Both sodium hyaluronate and sodium alginate maintain a higher mucosal elevation between 5-30 minutes when compared to other solutions (p<0.05). There is no significant difference in the height of mucosal elevation between sodium hyaluronate and sodium alginate injection.
